DISCUSSION OF WATER SUPPLY PLAN
Mr. Wegner stated that he would like to bring everyone up to date on the
discussion of the Water Supply Plan. On September 27th. the Tigard
City Council adopted the Murray Smith Plan as the long term water supply
plan for the Tigard water service area. It is currently being printed
and the final copies will be distributed within the next two weeks. He
stated that they have begun working on formulating the working plans as
to how to approach this. On the second page of the memo it states that
we are in the process of developing a newsletter with the hopes of
changing this every other month to accommodate the billing cycle. This
Will hopefully begin with the November billing cycle and will discuss
water activities. We have also begun negotiating withMurray Smith for
a second contract that would provide us with engineering and consulting
services as we proceed through the negotiations with Lake Oswego and
Tualatin Valley for the interim period of time. Meetings have been held
with the Director from Tualatin Valley Water District and Mike Miller
has meet with the Chief Engineer to discuss the possibility of providing
water for an interim period of time.
Hopefully the second week of November, we will be invited to a meeting
With Tualatin Valley to discuss "the. Willamette River. They have had an
engineering study done on the Willamette and will be sharing it with
interested communities. -
John Schwartz discussed briefly the past summer, the Wilsonville. area
being out of water. Mr. Wegner stated that they did initiate some water
restrictions during the summer. Mr. Schwartz stated that it was his
understanding tlfat'-their reservoirs were so low they were not -even--.abld -
to maintain fire flows. It was stated that Wilsonville does have some
water rights on the. Willamette and they are one of the interested
parties in a regional facility in that 'area. Some of the inter=ested
parties to this facility are..: Tualatin Valley, Tigard, Tualatin,
Wilsonville, and Sherwood.
J Mr. Schwartz stated the importance of talking with Lake Oswego but= at
-the same time -should be working:-,with other communities also. Mr. Wegner
stated that he would be attending a meeting on November 25th at
_---------- Corvallis on. the'--Willamette and-the. Water. Quality -Study that__Was ..dine.
Mr. Schwartz also .questioned whether there would be a time table. put
together that would outline when negotiations and other issues will take
place. Mr. Wegner stated that he would be Putting together a work plan
and timetable that he will be distributing within the next couple of
weeks.
Bill Scheiderich questioned whether Mr. Wegner or someone else on the
Board could summarize the intent of the Water District _Board and the
City Council as to interim .purchases of large volumes of water from
IWB BOARD MEETING - OCTOBER 12, 1994 PAGE 2
Portland. Mr. Wegner stated that if another source is available such as
TVWD, for the large volume, we would like to check on those
possibilities.
Mr. Scheiderich stated that the City of Beaverton is beginning
negotiations with Portland for an emergency water supply given that if
the water main on Murray Road is ever severed they would be dependent
upon reservoirs alone. For the interim there has been direction given
to negotiate with Portland for emergency or backup water supply. There
has been some discussion on obtaining that water from the Bradley Corner
connection. There is a 1973 Agreement whereby, Tigard Water District
and Metzger Water District both get 3.65 mgd in that line with Beaverton
having the right to construct a parallel line from Five Corners. There
has also been some discussion with Beaverton connecting further from
Bradley Corners to a connection with the Beaverton system and the Tigard
Water District at approximately where Hwy 217 goes under Hall Boulevard.
Chair Manning questioned whether Jack Polans had received_ a copy of the
Water Supply .Plan Update. Mr. Polans stated that he had not received a
Copy. Chair Manning questioned whether a copy of this could be provided
to Mr. Polans. Mr. Wegner stated that at this time there is a copy
available in the 'Library and we have no additional copies. Chair
Manning stated that she would like to request a copy of behalf of Mr.
Polans and if there 'was a cost issue, the City of Durham would pay for
that. Mr. Wegner stated that "there is also a copy available in each of
the respective City Admi-nistrator's offices.
Mr. Wegner stated that he had provided the Board with two months of
Water Reports (August and- September)•:- --Discussed the issue of Water
Quality which has been in the media lately. An article on taste and
odor was in the Tigard times and also the television media has been
running information, on cryptosporidium. He has also included in the
packets some information on the taste .and odor problem from Gary
Deadmond at. the Water Treatment Plant. Mr. Wegner stated that these
articles have also been provided for the Cityscape and also to the City
of Durham and King City =or their newsletters.
Mr. Wegner stated that in the last six months the City has annexed
- - fifty-six (56') acres- of land-and-the Ordinance :fora withdrawal. from the
Tigard Water District will begin.. Mr. Wegner's memo also addressed °the
water conservation coalition in this area of which Randy Volk is a
member of. They have put together a school program that, has distributed
to all the area schools for the teachers use. Northwest Natural Gas
program of shower conservation kits has distributed 3; 222 conservation
kits in the Tigard Service Area upon requests. This is about 1/4 of the
customer base for the service area.
All three cities have approved the Resolution adopting the Division of
Assets Report and next week the Tigard Water District will have it on
their agenda for approval. After approval by the TWD, we will have a
final copy prepared and distributed to all the parties.
IWB BOARD MEETING - OCTOBER 12, 1994 PAGE 3
Maintenance Services has moved the Vehicle Maintenance operation to the
Water Building facility which were built and designed for vehicle
maintenance. Tigard Water District had in the past contracted out all
of the vehicle maintenance and we are currently doing that in house
which will reflect a savings.
Chair Manning discussed the mandatory notice for the lead and copper
program, and questioned whether there have been many requests for
sampling?
Mike Miller stated that we have had a few requests, but not many. Mr.
Wegner stated that there has been a lot of calls regarding the taste and
odor problem.
Mr. Wegner stated that this is the first month for combined billing on
a regular cycle. A lot of residents in the Tigard Service Area received
utility billings in excess of $100 for a two month period, which
included water, sewer, and storm water charges. Mr. Wegner stated that
the Finance Department is considering changing the billings to say City
of Tigard Utility Bill versus City of Tigard Water Department.
John Schwartz questioned what the average increase on sewer bills were
since we have gone to the water consumption formula? Is this rate
linked to water charge increases or sewer charges? Mr. Wegner stated he
'would check and find out the figures from USA.
NEXT AGENDA ITEMS

MEMORANDUM
CITY OF TIGARD, OREGON
TO: Intergovernmental Water Board Members
FROM: Liz Newton, Community Involvement Coordinator
DATE: April 15 , 1994
SUBJECT: DRAFT Bylaws
Attached is a revised copy of the DRAFT IWB Bylaws. The section on
Voting and Motions has been clarified to reflect that a majority
vote of the Board is necessary to pass motions.
I have ordered five copies of the pamphlet on Conflict of Interest
from the Oregon Government Standards and Practices Commission. An
appropriate reference to that document will be included in the
bylaws. In addition, a reference regarding Parliamentary Authority
will be added after the City Recorder makes a recommendation.
As I pointed out at your meeting on April 13 , the Board may want to
consider their obligation to appoint a Chair-Elect in the event of
a mid-term resignation. The last paragraph on page one of the
DRAFT Bylaws require the Board to fill that vacancy at the next
available meeting. The Board may want more flexibility if there is
only two or three months left of the term.
If after discussion, the Board agrees to other modifications,
additions, or, deletions, the changes will be made and presented to
the Board prior to adoption. If no additional revisions are
necessary, staff will present the final version for adoption.

years.
H. Portland Regional Water Supply Plan-Phase 2 (May 1993-Nov. 1995)
A recent guest column in the Oregonian began with a seemingly simple question:
"Which would you rather drink: water from the Willamette River or from the pristine
Bull Run Watershed?" It is the kind of question that 27 Portland area water providers are
asking. The Portland metropolitan region is facing some tremendous growth pressures,
and future water supplies are part of the fabric of how and where this region will grow.
Historically, about half of the residents of the Oregon metropolitan area have been able to
drink Bull Run water, which comes from one of the most protected watersheds in the
country, thanks to a century of careful development and protection. This water source
has developed a mystique and is of very high quality, free of the risks that face many
other municipal water supplies for cities of similar size. The residents of the other half of
the Portland region are served by a variety of other water sources; from the Clackamas, to
Trask/Tualatin, to individual smaller surface and groundwater sources. All of the supply
systems that are currently available will not be enough to meet the needs for the next 50
years, during which time the Oregon side of the metropolitan area is expected to grow by
some 800,000 new residents.
Where will the water come from to serve this future population? Answering that question
is the central task of the metropolitan areas' regional water supply planning effort, which
is jointly funded and now in its third year. It's a comprehensive and complex process in
which our options are being examined so that the hard choices facing us can ultimately be
made. Our basic options are fairly clear:
• Conservation- As with any precious resource, conservation offers us a way to ease the
crunch. The drought of 1992 was a wake-up call that prompted the Bull Run water
system users and others to reduce their per capita water consumption by about 10%. We
can achieve much more than this, and a major focus of the planning work is identification
of ways to implement various levels of conservation. The regional supply plan is also
looking at possibilities for re-using water. Major water users such as the Port of Portland
are looking at using non-potable water in dual systems for its industrial needs. Because
of their expense, dual systems may only be practical for larger irrigation uses such as
parks and open space settings, industrial and institutional users.
• A third dam in the Bull Run to increase its holding capacity- The watershed's
incredible productivity and the natural quality of its water make this an attractive
alternative. Any future construction, however, will have a daunting series of
environmental hoops to pass through. No one's crystal ball is clear enough to show the
outcome of those future dealings,but it would be foolishness to stake the entire region's
water future on the assumption that a third dam will be built as our sole future source.
• The Willamette River - the Willamette, Oregon's major river system, is augmented in
the summer with flows from eleven existing Corps of Engineer's dams. Other
communities in upstream areas make use of the this source now. The primary concerns
about this source have to do with its water quality, the need to retain adequate instream
flows to protect other uses for the river, and the cost of using this new source.
• The Columbia River - this is the nation's second largest river system and it has flows
larger than any other river in the west. It has not been tapped directly for municipal
supplies as far downstream as the Portland region,but preliminary pilot test results show
that it does have some potential. The concerns about this source are similar to those for
the Willamette, particularly in light of the fragile health of Columbia basin salmon runs
and the potential for water quality problems with such a large upstream drainage area.
•The Trask River-The Joint Water Commission which serves part of Washington
County is proposing the four-fold enlargement of the Barney reservoir. The existing
reservoir is located high in the head waters of a fork of the Trask River. This project
already serves part of the Washington County area and is currently in the environmental
impact assessment and permitting stage.
• Aquifer Storage and Recovery (ASR) - ASR is a technique which takes surface water
flows from any of the existing or future water supply sources, injects it into the ground
through wells and then pumps it back out during the periods of need, which could be
summer's dry months or in an emergency. This technology, while new to this region,is
being used in many parts of the southern and southwestern United States. Several aspects
are now being studied, including impacts on winter surface water flows, aquifer
protection, chemical mixing of the waters, and the amount of water which such storage
might yield.
The region's water providers will continue to study the key issues before completing a
preliminary regional water supply plan which is scheduled to be issued in 1995. In the
meantime the region's water providers and decision makers are encouraging the public to
take advantage of the public involvement opportunities built into the regional water
supply planning process. We need to hear public opinions on how we should meet our
future water supply needs. Based on the results of recent surveys, interviews, and public
forums held so far we know that our region contains very diverse interests.
We have heard clear messages about the central importance of conservation as we
proceed into the future. We must also carefully weigh the costs and public health risks
associated with the needs for water treatment of the various sources. We must weigh the
environmental tradeoffs which might be required to meet these future needs. We must
assess the overall costs for new supplies and the equity issues involved with who has to
pay.
The questions are multiple and complex, without easy answers. Yet choices will need to
be made throughout the metropolitan area. We anticipate that no one option will meet the
needs of the entire region. The public deserves to know what the choices are.
III. Issues as they relate to the Willamette
The Portland population currently obtains about 65-70% of its water supply from out-of-
basin diversions (Trask& Sandy basins). The future may not allow that same level of
out-of-basin diversion. The Phase 2 process is evaluating both increased out-of-basin
diversions from these same sources as well as developing sources on the Columbia River
mainstem and on the Willamette River as well as the Clackamas River(tributary to the
Willamette). The title of this presentation is very aptly named,the Willamette Basin
clearly presents a very real challenge to all users of the system,both instream and out of
stream.. The bind that water providers find themselves in, even if they are able to pull
together a regional look at their water supply needs, is how these needs fit in with the
other demands on the system. Two key areas of uncertainty include:
1) Not knowing the instream needs for the Willamette mainstem and its tributaries for
such uses as fisheries, water quality,recreation,and navigation. There are 24 instream
flows which were established for the Willamette and tributaries by the State in the
1960's and early 1970's many of which contain a "natural flow" component and a
storage component to them. These were to be converted to instream water rights
(ISWR) as a part of the adoption of the statute which established ISWR in 1987
legislative session. Most of the MPSF around the state have been converted except for
these in the Willamette system. They present a special challenge in terms of the
complexities of priority dates and the two different components and the contractual
issues revolving around the 11 Corps storage reservoirs. The conversion of these
minimum streamflows is, however,limited to the natural flow and storage components
of their original adoption which will limit their ability to protect the natural flow part
of Willamette flows. On the lower mainstem Willamette in low flow months the
minimum streamflows anticipated about 1/4 natural flow and 3/4's storage component
but the actual flow components in an average year appear to be about 1/2 for each type
of flow, leaving a "technical" water availability excess in natural flow. This means
that the converted streamflows will not be able to protect all of the natural flow found
in the Willamette during low flow months. Therefore the larger issue is just what is
needed instream to protect fisheries and other species of concern, recreation, habitat,
and to assimilate pollutants that flow into the system. The flow targets of the
minimum streamflows would seem to have validity in the system in that DEQ has
based their permits for discharges based on these amounts and in the low flow period
of 1992 when the targets were not met for the lower river there were fish mortalities
observed. Knowledge of this benchmark is important and it has presented a real
problem not knowing what is required to meet these various needs, particularly in light
of the second major issue.
2)The Willamette flow pattern is heavily influenced by the release of storage from eleven
Corps of Engineers reservoirs, primarily on the eastern, or Cascade foothills side of the
valley. These releases augment summer flows considerably and have enabled a flow
target of about 6,000 cfs set for the river at Albany and Salem to be maintained, in
spite of increasing diversions from the river and its tributaries. T lie conversion of the
MPSF has been wrapped up in this storage and natural flow issue. However, the Corps
has conducted the first part of a study to look at how this system might be augmented
and they and the State are engaged in developing a scope of work and budget for doing
a "feasibility" study for reauthorization of the Willamette projects. The price of
purchase of Corps storage is substantially higher for M&I purposes than for irrigation,
however, it is not even clear that M&I contracting can take place in face of the current
authorization for the projects and due to two existing storage permits held by the
Bureau of Reclamation for all of the currently available storage water for irrigation
purposes. The operation of the Corps reservoirs may be able to insure that needed
instream flows are present and allow some further use of the river for out of stream
uses. A study of the operation of the Corps storage projects in the Willamette system
to meet changing multiple purposes is needed.
The water providers of the rapidly growing Willamette Valley must do infrastructure
planning not only because in some cases it is required under the State Goals and
Guidelines/Comprehensive Planning requirements but because it is a responsible thing
for water providers to do. In the circumstances noted above for the Willamette it is very
difficult to do an adequate alternatives analysis for meeting future water needs with the
number of unknowns evident. This may drive some decision makers to use short term
fixes which could result in a wasting of resources to develop less desirable sources.
Water providers in the Portland area are attempting to look at the issue of future water
needs in a larger institutional framework which in part gets past the fractionalized aspect
of so many providers,but Valley-wide there are a number of different water providers.
Bringing us all together is being done to some extent with the reservation application
process. Some increased coordination of water providers with wastewater providers has
occurred in parts of the Willamette Basin, but more needs to be done to merge the issues
of M&I water cycle. This cooperation in and of itself is an improvement over the past
processes,but in order for the providers to be able to properly evaluate the relationship of
the various demand management measures with the various water sources represented by
the surface and groundwater in the Willamette valley, the issues mentioned above should
be either resolved, or better understood. The "ripeness" of these issues is ready for
regional resolution, but the role of the state and federal governments are important and
necessary if more effective water management decisions are to be possible.
Water providers do not want to be put in the surrogate role of becoming decision makers
about growth. In the Portland study we are working with Metro in their 2040 process to
offer alternatives to meeting the growth needs represented by the growth form decisions
of Metro and the other local governments. Water providers should be able to give land
use and growth management efforts some information about the water supply impacts of
growth and its form. However, not enough is known about water use in relation to
different types of development patterns here in the NW, this should be added to the
research agenda. In addition, water providers should be presenting to their publics and
decision makers real alternatives in the areas of demand management, to compare with
new or expanded sources of supply, the future potential costs of added treatment needed
to meet increasing water quality standards, the potential for water reuse,choices about the
reliability of a water system to meet all demands under various weather scenarios,
regionalization to maximize the use of existing water rights and supplies and the risks
implicit with selecting certain alternative ways of meeting future demand.
There appears to be a dual challenge to moving through the thorny problems presented by
wise water management in the complex Willamette system. From a municipal providers
perspective these dual challenges are:
1) The state needs to play a leadership role to establish the basin wide coordination
necessary to address the issues of instream flow needs and the operation of the
federal reservoir projects. Movement has occurred on these issues, but the
commitment of all the state agencies in a coordinated fashion is needed as well as
the resources to complete a more comprehensive look at instream flow targets and
reservoir operations. Some exciting work in basin modeling is available from
other parts of the country, including the Seattle/Tacoma area, and federal agency
coordination through EPA on basinwide issues seems to be moving forward.
With the potential for ESA listings and increased Clean Water Act violations
present coordination and resources from the federal level should be sought and
supported by the State.
2) A comprehensive look at Willamette basin wide issues should be supported by the
water and wastewater providers in as active a fashion as possible. In the
meantime, the municipalities and water districts need to think in new ways about
demand management, system reliability, and alternative sources of supply. New
planning techniques can be applied in deciding how to meet future water needs. It
is important to look at water needs beyond traditional single unit jurisdictional
boundaries and to evaluate the resource in relation to the other demands being
placed on that resource, particularly during any time frame before the Willamette
Basin issues mentioned above are resolved.
3) Efforts to address overall watershed management should be encouraged at the sub-
basin level in the Willamette. All affected stakeholders should be involved in
such a way that cross jurisdictional boundaries are not an impediment to problem
resolution. The nexus of land use planning and watershed health should be
improved over time as a part of these efforts which may offer the greatest
possibilities for reaching sustainable communities in the Willamette Basin.

MEMORANDUM
CITY OF TIGARD, OREGON
TO: Intergovernmental Water Board
Tigard Water District
FROM: Ed Wegner, Director of Maintenance Services
DATE: October 10, 1994
SUBJECT: Various Water Issues
1. WATER QUALITY
a. Taste and Odor. Attached are memos regarding the Lake
Oswego Water Supply. Many calls have been received from
our customers questioning the quality of our water. As
the memo explains, we are experiencing a temporary
situation which will occur to some degree annually.
b. Crptosporidium. Recent national news programs are making
the public aware of a relatively new problem that effects
water systems. The attached memo from the Chief Water
Plant Operator for Lake Oswego is provided to you so that
you are aware of the issue. The plant is not presently
testing for crptosporidium, but is taking prevention
steps to keep the problem out of our treated water.
2. ANNEXATIONS
The City is preparing and ordinance for the withdrawal of
approximately sixty acres from the Tigard Water District.
These parcels have been before the Boundary Commission
and approved. Those parcels are the same as we indicated
last month.
3. WATER CONSERVATION
a. The Columbia-Willamette Water Conservation Coalition (we
are a participating agency) is attempting to create a
working relationship with schools throughout the region.
The programs are broken down according to grade level and
are funded through our own budgets at no cost to the
schools.
b. Northwest Gas Company Water Conservation Program, at last
count, 2,694 water conservation kits have been
distributed to customers within our service area as of
September 2nd.
,,. 4. WATER SUPPLY PLAN - Various activities are starting as we
begin this project.
a. Staff is developing a newsletter that will be a stuffer
in the bills being updated monthly to cover the billing
cycle.
b. MSA is preparing contracts to assist the City of Tigard
in further developing the Water Supply Plan.
C. Initial talks with Tualatin Valley Water District,
regarding an interim water supply plan have begun.
d. The City Administrator is preparing for his initial
meeting with the City Administrator for City of Lake
Oswego on a water partnership.

InterOffice Memo
To: Randy Volk
From: Richard C. Sattler
Date: September 26, 1994
Subject: Water Quality Complaints
As you are well aware of I have been spending a majority of my time answering
questions about the quality of the water. I would venture to guess that the duration has
been over the last month and a half. The amount of calls have ranged form 50-75 calls
per day regarding this issue. Of these 50-75 calls per day, 1-12 require my attention.
I have listed a few of the descriptive terms used: sewer water; is this Tualatin River water
we are drinking; aquarium water; water with earthy smell; horrible water; etc..
Reasons for the increase of calls regarding water quality:
1). increase of water temperature of the Clackamas River
2). increase of growth on the river(algae)
3). rains of the labor day weekend stirred up the water in the river
We are not alone, the City of Lake Oswego has also noticed an increase of customers
complaining about water quality. Due to the increase of calls,Lake Oswego has added
carbon to their treatment of the water. Carbon is known for absorbing/removing
the taste and odor of the water. I have been told that this process is time consuming,
messy and costly. I would also like to note that this a yearly event,with this year being
particularly bad.
When I receive a call concerning the water quality I volunteer to take a bacteriological
sample from their location(usually inside the house from a kitchen or bathroom faucet).
My theory is that by having a piece of paper, (the bacteriological report from the
laboratory) I am able to give the customer documentation of the water quality. The
results are usually given via telephone, unless the customer requests a copy of the
bacteriological report.

Subject" Taste and Odor Problem
rve been hearing abautt the taste gad odor gmblems with Clackanm River water for about a
month now. All of the water providers(SF VM.C1ackariias WI),Lance Oswego)appear to be
having significant T&O problems and the customer complaints seem to be increasing as the
problem continum rve bad a few drinks of water from various Places in ttae service community
and there is definitely a noticeable earthy/musty taste and odor to the water-
We've had quite a bit of experience with T&O problem of this kind thoughout the country.
�.%Q types of probjews usually occur when the water is warm and are dually,but not always,
associated with algae blooms in reservoirs. Bruce H,enrenway said there is quite a large algae
bloom in North Fork Reservoir right now. I've heard that the Clackamas River systems have
e*'�Pcna)cod mild T&O Problems hko this in previours 8uln em and early falls,but never to this
I vmwd suspect drat fire 1oa&loot.dry summer has the biggest impact on spurring the
bloom.
GA(musty odct's are usually caused by the presence of very small concentrations(int the parts
per bdliQu range)of mathylisoborneai 0d1B)and/or geosmin. These organic compounds are
formers as by-products of the-metabolism of algae and actinoruycetes. It is believed that lite
compounds are created when the algae die. These compounds are very difficult to remove from
drinking water via normal treaty wt processes. Sometimes,the addition,of chlonw will increase
the intensity of the eartIvImusty odors. I would recoannend that some samples are taken to
verify die pmseave of MM/geosmin.
We have conducted many pilot and full-scale tests on the removal of these types of tastes and
odors. in summary.T&O control can be ac emplished via oxidation or adsorption. The only
oxidant which has demonstrated a pnrvert ability to destroy the compounds is ozone. Neither
chlorine,permanganate nor Peroxide are sting etzougb to oxidize MIB and geosmin. This is
why i doubt whether KMInC4 will resolve your problem,but it is easy enottgk to try it and see
for yourself. As we discussed,I would suggest you add it at the intake to jncrease the contact
tim and to minimize the potential for"pink water" if you overfeed it_
Activated carbon can adverb 3ifWgeo&min. Powdered activated carbon(PAC)has baea
successfully used in some WTPs,but the required doses are usually quite high(greater than. 15
mg/L PAC !!). Many operators are reluctant to use such high doses for fear that the PAC will
carry over from the Wdjmevtatlon basins and break through the filters. You can evaluate the
r0bets of PAC dose in jar tests,but you'll have to be careful how you conduct your"sniff test".

rw plants without ozone system,granular activated carbon(GAQ has been the most sucessful
method of mmviag MWgeosmim However.in order to provide the ncccss$ry WOW time.the
anthracite in the taw is typically replaced with GAG. Many W TPs have added a GAC cap to
their fitters and d9s has been able to sigWfic antly reducc T&O complaints. The CMC's useful
adsorpfion life can be 5 years or more depending on the background TOC and frequency of T&O
episodes. The one problem with this method is that it must be used all the time at a significant
fust4lme cost,but the T&O problem isn't present throughout the year. The cost to replace your
anthracite with GAC would be approximately$150,0M. For comparison purposes,the
construction cost of a new ozone system would be aNwximately$1,000,000.
The City of Corvallis has been experietwing various kinds of tastes and odors from their
Willamette River source for many years including earthy/musty odors during the summer. They
are currently evaluating methods for reliably controlling T&O at the WTP. I believe they are
seriously considering replacing the anthracite with GAC. perhaps you should call Dan Scottie
and discussson the situation further with him.
U'nforMnately,there sloes trot appear to W a"quick fix`for this type of problem. It may be
difficult to rmlve the T&O problem this year and it will resolve itself eventually when the
weather cools orf and the Was come. However,you may want to consider the options for
resolving the problem should they rye-occur in future years.
Please call me if you have any questions or comments. Thank you.

RE: CRYPTOSPORIDIUM
♦X46164644466664444446444464664444446644444444446
WHAT IS CRYPTOSPORIDIUM?
Cryptosporidium (crypto, meaning hidden and spore, meaning seed or germ)
is a parasitic protozoon that survives well in cold water and forms a cyst
(known as oocyst) in adverse conditions. It is similar to giardia (beaver
fever), microsporidium, and cyclospora. These organisms can commonly be
found in lakes and rivers.
WHY IS IT DIFFICULT TO KEEP OUT OF WATER SUPPLIES?
The cryptosporidium cyst is very resistant to disinfection by chlorine. It has
reportedly resisted chlorine several times stronger than the normal dosage
used in water treatment plants for several hours.
WHAT IS ITS HISTORY AND HOW SERIOUS IS IT?
Cryptosporidium was first identified by a veterinary scientist in 1974 as the
organism causing gastroenteritis in a Tennessee farm girl named Regina
Gibbs. Later outbreaks of cryptosporidiosis include San Antonio (1984, 2000
ill), Carrollton Ga. (1987, 13,000 ill), Jackson County, Ore. (1992, 15,000 ill)
and Milwaukee, Wis. (1993, 370,000 ill). In the last mentioned outbreak
several people died. People most susceptible include those infected with
AIDS and cancer patients undergoing chemotherapy. Symptoms include
diarrhea and vomiting lasting for up to a month in healthy individuals.
Some women sufferers have developed antibodies that attack their own blood
platelets causing serious bleeding disorders. Obviously cryptosporidiosis is a
more serious disease than the better known giardiasis.
HOW CAN THE PUBLIC BE PROTECTED?
The cysts can be removed by good filtration. The outbreaks in
Carrollton, Ga. and Milwaukee, Wis. are of interest to us because both were
caused by filtration plants that allowed the cysts to pass through the
filters into the distribution system. Given that the cysts are very resistant
to disinfection by chlorine, good filtration is the primary protection against
disease outbreaks of this type. In the Carrollton, Ga. plant, for example, the
combined filter effluent met all federal turbidity standards,but because
monitoring of individual filters is not required it was not discovered that one
filter was not operating efficiently. That filter allowed enough
cryptosporidium cysts through to contaminate the finished water without
violating the federal turbidity standard.
LAKE OSWEGO FILTRATION PLANT PREVENTION STRATEGY
What is done at the Lake Oswego filtration plant to keep cryptosporidium
and other protozoa cysts out of the treated water?
• Each filter is fitted with its own turbidimeter. Each filters effluent
turbidity is prominently displayed on the filter backwash control board
and recorded in the computer. High turbidities produce an alarm. A
record of each filter's performance for the past day, week, or month can be
printed from the computer for examination.
• Plant "target" for turbidity is less than 0.1 NTU as opposed to 0.5 NTU
required by federal standards.
• "Filter to waste" operation is required when filters are not producing at
least_ 0.3 turbidity. This can happen during the short 'conditioning' period
just after a backwashed filter is returned to service.
• A Streaming Current Monitor controls coagulant dosage to optimize floc
size for filtration.
WHAT ELSE CAN BE DONE?
A particle counter will be purchased to monitor particle numbers and sizes in
filter effluents. Particular attention will be paid to inhibiting passage of
particles the size of protozoa cysts through the filters.
DOES LAKE OSWEGO TEST FOR CRYPTOSPORIDIUM?
Not at present. We have contacted Nielson Research in Medford about
testing for giardia and cryptosporidium. We will be required by law to test
every other month for eighteen months beginning October 1995. Each test
requires filtration of 1000 to 1800 gallons of water, mailing the filter to
Medford and a fee of$389.00. The required tests will be mainly for EPA
research purposes. Because protozoa cysts are so widely interspersed in
raw and much more so in finished water a negative test does not necessarily
prove that no organisms exist. The best protection is to maintain good
filtration techniques.
CONCLUSION
No water treatment facility can guarantee that a water borne disease
outbreak will not occur. What it can do is do the best job possible by keeping
abreast of current technology, maintaining operator training at a high level,
and keeping equipment operating at peak efficiency. The staff at the Lake
Oswego Water Drinking Water Plant is dedicated to doing just that.

Work Accomplished:
Durham
• Water Division personnel extended two 3/4-inch water services behind a
proposed new sidewalk. Water staff also responded to a few requests to
check for water leaks at the customers service due to high consumption.
• Water Division personnel installed a two inch water service and meter for
Durham Park.
King City
*41W • Water Division personnel replaced three 5/8" x 3/4" water meters that
were damaged or stuck. Also, Water staff responded to a few requests
to check routine pressure problems and determine if water leaks were on
the customer's side of meter, on our side of the meter or whether a water
leak actually exists.
Unincorporated Area
• Water Division personnel repaired two water services that were damaged
or needed to be relocated to the proper location. Also, Water staff
replaced'two 5/8" x 3/4" water meters that where malfunctioning and
adjusted the water pressure at a few individual homes throughout the
service area.
• Water Division personnel installed nine 3/4-inch water services for
Chardonnay Estates, a single family residential development located at the
terminus of SW Chardonnay Avenue, south of SW Bull Mountain Road.
• Water Division personnel installed 8 -3/4" water services and one water
sampling station for Crest Ridge, a single family residential development
located at the north end of SW Chardonnay Avenue just south of SW Bull
Mountain Road.
• Water Division personnel continued with adjusting valve boxes along SW
Bull Mountain Road for the Bull Mountain Road Bike and Pedestrian Path
improvement project.
City of Tigard
• Water Division personnel installed 25 - 3/4" water services and one water
sampling station for Rose Meadows, a single family residential
development, located between SW Fern Street and SW Walnut Street.
• Water Division personnel repaired the 24-inch water transmission main on
SW Tiedeman Street,just north of SW Walnut Street. A leak developed
from the failure of a stainless steel band that was installed to seal a leak
when a boring machine for cable TV struck the water main ten years
earlier.
• Water Division personnel installed 29 - 3/4" water services and one water
sample station for Renaissance Summit. This development is located at
SW 109th Avenue and SW Naeve Road.
• Water Division personnel installed 34 - 3/4" water services and one water
sample station for MorningStar Phase 1 and 2. This development is
located south of the terminus of SW 132nd Avenue, south of the
Benchview subdivision.
,, • Water Division personnel replaced a fire hydrant that was damaged on SW
Morning Hill Drive and SW 135th Avenue.
• Water Division personnel replaced ten 3/4-inch pressure regulators, eleven
5/8" x 3/4" water meters that were damaged or malfunctioning. Also,
Water staff repaired five 3/4-inch water services that were damaged.
• Water Division personnel replaced and upgraded the existing air release
valves located on SW 121st Avenue and SW Rose Vista Drive.

Status Report:
MSA (Murray Smith and Associates) to released the first draft of the Water Supply
Update study in mid August.
Phase II of the SCADA (Supervisory Control and Data Acquisition) system is 80%
complete. Phase II included the purchase of a new software program, "Wonderware
InTouch", that provides an graphical interface between the raw data that is collected
and the operator. The Wonderware InTouch program will not replace the existing
SCADA program, but provides an enhancement to the data gathering and
manipulation capabilities of the SCADA program. The most important feature of the
Wonderware InTouch program is its ability to provide real time and historical
trending, which we did not have with the original purchase of the SCADA system.
• Training of Water personnel on the usage of the Wonderware InTouch software was
completed mid August by factory personnel.
• RTU's (Remote Transmitting Units) were installed, but a couple of the RTU's had
malfunctioning computer boards that had to be sent to the manufacturer to be
reprogrammed or replaced. Completion of Phase II of the SCADA system is expected
to occur in September or early October.
Complaint Summary:
During the last week of August,we have started to receive a few complaints regarding
taste and odor problems with the Lake Oswego supply. This is earlier than usual, but
due to the low river conditions and warmer river temperature, algae growth has
developed. The Lake Oswego Treatment plant has started to use activated charcoal in
the treatment process to control the taste and odor problem.
Operational Changes:
John Acker was named Property Manager for the new Property Division that includes
grounds, streets and building maintenance.
At the end of August, Fleet Maintenance began to move its operations into the Water
Building. One of the reasons for this move is so that Fleet Maintenance can utilize
the two bays of the shop/mechanic area at the north end of the building which are
more modern than the existing shops at Maintenance Services.
