® 4� 1
stated that if the answer was not discussed regarding Mr Denton it would be

Commissioner Roude stated that this item being discussed later in the nunutes
would place in on the public record
Mr Monahan stated that in reference to Mr Polaris's question, Mr Wegner was
more involved in that negotiation and he would be discussing that in Executive -
Session later in the evening. Mr Monahan continued by saying that he was
involved with some discussion with the City of Wilsonville.concerning possible
participation of this group in a water treatment facility but they have not met
recently regarding this matter More recently discussion has been held on water
rights collectively that the various Cities.and Distncts in this area have been
pursing on the Willamette River Mr Wegner will be discussing these matters in

this information? Mr Monahan stated that the discussions that have been held
have been for a potential contract and this information is privileged and discussions
have been held in Executive Session and are not available to the public at this time
4 Approval Meeting Minutes- January 8, 1997
Commissioner Hunt questioned on page six of the above noted nunutes, that the
top line be changed to reflect entities versus Cities Mr Hunt also stated that on
that same page the minutes referred to a ten man steering committee and
questioned whether,those members were from the technical subcommittee Mr
Wegner clarified that there is a'technical subcomtruttee which consists of twenty-
six members, and from that committee ten people were selected to make up the
Steering Committee Commissioner Hunt moved to approve the minutes with the
above corrections which was seconded by Commissioner Carroll and passed
unanimously
5 Request for Facility Use- Bill Monahan
Mr Monahan began by sharing some background information on the facility use
matter and displayed some floorplans Mr Monahan continued stated that
approximately one year ago the City was conducting studies on the long range
space needs were, at which time he came to the Board and requested some
potential use of the Water facility for City offices This building is currently owned
by the three Cities and the District (Tigard percentage is 78%) This facility was
used for the Interfaith Outreach Group,for a severe weather shelter for two'years
Use was also requested from the Board to erecta mono pole with the Board's
approval This Board has expressed that if the facility space is needed in the
future, with appropriate notice and discussion this could be ok Mr Monahan
stated that the City has investigated many alternatives in regards to space needs

including acquisition or expansion. Mr Monahan stated that since the City is
working with Washington County to take over some of the duties (Planning,
Building and Engineering) for the unincorporated area of Washington County that
are in the Bull Mountain Area and the Walnut island. It was initially thought that
this would require two to three additional staff people based on the estimates of
the volume.of work, andnow we are finding that this will require ten new
employees. Mr Monahan continued by discussing the various City facilities and
the departments that they house as follows City Hall with Adnunistration, some
Finance, Police, Community Development and Engineering,'Water Facility the
remainder of the Finance department for utility billing and water services, SCADA
system and some other water personnel in the rear of the building and the Water
crew out in the bay as well as Fleet Services and the Public Works Facility on Ash
Avenue -On,the corner of Ash Avenue and Burnham there is a small building
(1,800sq ft)`wluch currently houses the Interfaith Outreach Services This
building will betaken,back by the City when IOS vacates those premises The City
also has the Niche which includes Human Resource facility, Network Services,
Risk Manager and Purchasing staff. Mr Monahan continued by stating that this
has been a difficult process to determine which employees and divisions can be
moved and still service the public efficiently We are now looking at this facility
since there is extra space available Mr Monahan displayed a drawing of the
Water facility and its current inhabitants Mr Monahan stated that the City would
propose to move a few people to the Water facility from City Hall in the first step
of a yet to be determined long/short range plan At this time, it is known that we
need'to move additional people into City Hall related to the new service (Building
Inspectors, Plans Examiner, Engineering Technicians, Current Planner and
r Secretarial support) and move some people out (Senior Planner, 2 Associate
Planner; Map/Graphic person) to make room for them. This plan will move 4
employees out of City Hall and 10 new employees in Mr Monahan stated that the
City Council.has not taken final action on-this plan. Another plan is to move
another 2 people from.City hall for a total of six and move in 10, which•is-not a
favorable plan This plan would move Rich Sattler and the Scada System over to
the Public Works facility
When the.IOS's new facility is constructed they will vacate the building on the
corner of Burnham and Ash and a decision will be made who could best occupy
that facility
Commissioner Kloster questioned the purchase of a modular facility at City Hall?
Mr. Monahan stated that we currently have a modular facility at City Hall.for the
past nine years which houses 12 employees We have looked at the option of
bringing in another triple wide facility with 2,600 square feet and move the
Engineering Department into that new facility and free up the existing space This
would cost approximately $9000 which we would hope to recover from
Washington County since the arrangement is for them to make the City whole
® The problem with this option is the time element since a custom,made unit will

take approximately 120 days The Board discussed the time frame on the IOS
occupancy of the building on Burnham/Ash. IOS may vacate the prenuses.as
soon as the end of July but this option has a lot of details to be worked out first.
Another option that has been considered is a rental/lease agreement on the U_mfied
Sewerage Agency facility on Durham Road and'Hall Boulevard.
Comnussioner.Froude questioned whether Mr Monahan would attend a Tigard
Water District Board meeting-to discuss this matter since she did not feel she was
in a position to make this decision and he agreed. It was discussed that a special
meeting may be called to hear this matter
Commissioner Carroll questioned how the proportionate amounts of the building
ownership works? Mr Monahan stated that when the withdrawal from,the Water
District occurred they moved a lot of employees from the facility to Public,Works
since all employees became a City employee Finance was moved in since they
were blended with the utility billing employees The City has been sensitive to not
overuse the facility with City employees Mr Monahan stated that we have always
attempted to maintain that the people that are performing water functions remain
in facilities that are better.than the facilities that existed before the building of the
Water facility Commissioner Carroll questioned who controls the Water facility?
Mr Monahan stated that the facility is controlled by the City of Tigard as-it-does
-all-the,day to day operations Mr .Monahan stated that-the.agreement of the four
parties delegated all the responsibility for providing water service,to the area and •
to-manage all facilities, but due'to political and customer-, services concerns, the
City had,attempted to defer decisions onto the IWB The Water facility was built
by the Tigard Water District with water funds The governmental'bodies of the
three entities had no say in the operation of the Water District since it was.a stand
alone separate government entity (Special Service District) Commissioner Hunt
stated that the division of assets was completed at the time of merger and.divided
accordingly with the combination of meters and patrons The formulas.and the
division of assets were agreed upon by each.entity Mr Monahan continued.by
stating that his goal was to get some direction from the IWB members on when a
temporary move is made by the City would the,Board agree upon option a)
moving four FTE's or option b).moving six FTE's Mr Monahan stated that he
would,go to.the Tigard Water District as well as any of the other entities if needed
Commissioner Froude questioned the time frame of needing a decision? Mr
Monahan stated that the issue.of the Urban Services will be discussed at the March
25 City Council meeting with hiring of some of personnel by April 15
Commissioner Hunt stated that his view was.that we are spending,tax payers
money to buy additional facilities to,accommodate space needs when ithese
facilities are not being fully utilized. Commissioner Carroll agreed with Mr Hunt
and Commissioner Froude stated that she was not at liberty to make this decision
for the Tigard Water District. Mr Monahan stated that he feels that the
perception is•that the Water facility belongs to the City Commissioner Carroll

questioned whether the City had done a space needs analysis. Mr Monahan stated
that the City had in the past determined the square footage utilized by each division
which showed that more space is being utilized by the Water Division in office
space at other City facilities than the City is utilizing in this facility
Representatives from King City and Durham stated that they did not see any
objection to the space utilization. Mr Monahan stated that'he will schedule to
meet with the Tigard Water District and will proceed if the group agrees
6. Consortium Update- Paul Hunt
Commissioner Hunt stated that the Consortium is relatively new group which is an
extension of the technical group which Mr Wegner has participated on-for the past
three years 'The Consortium'group is made up of twenty-six entities in the tri-
county area that are conducting�a long range study of water needs. The technical
group can-bring recommendations to the Consortium for decision. The technical
group had their first meeting one.month ago and elected Bob Mitchell from
Tualatin Valley Water District as Chairperson, a vice chair was not elected at that
meeting but will elect that position at the.next meeting. Commissioner Hunt stated
that the group is represented by all different size agencies and each has one equal
r vote Based upon Portland Water Bureau size and1nowledgewill be taking the
lead role

with elected officials from throughout the region. The next board meeting will be

7 Menlor Reservoir Update- Ed Wegner
Mr Wegner stated that in the packet distributed tonight was information regarding
the Menlor site Mr Wegner stated that we are continuing to negotiate,for
purchase of property easement and waiting to hear from the property owner's
attorneys The document that was sent by MSA have been forwarded to the City
attorney for the bidding process Two mayor situations have developed that will
alter the cost of the Menlor Reservoir site One study was required to determine
where the rock was and this test revealed shallow depth rock and there is also a
concern-by Unified Sewerage Agency regarding the discharge of chlorinated water,
which will require extra design measures to prevent this from happening.
The increase in this project will be between 25-46% higher, with a.total estimated
project cost-of 3 6 million. The funds are available and we are staying within the
15% contingency amount Commissioner Carroll questioned whether the City was
® acquiring an permanent access easement Mr Wegner stated that this would be a
yfir•'1SU��S

yP
permanent access easement to the reservoir site and the City may need to purchase
more property than originally intended to satisfy the property owner
Commissioner.Carroll also questioned even though the solid rock will increase
excavation cost, will it help reduce construction cost? 'Mr Wegner stated that this
will not be a significant offset. Mr Wegner also stated that the information packet
included a quarterly report from Murray, Snuth and Associates
8. ADA Facility Compliance- Memo
At the January meeting Loreen Mills was in attendance to discuss the need to
upgrade and complete a study to ensure that we were in ADA compliance with the
Water facility The reservoir sites were assessed one year ago The Tigard Water
District did have questions regarding the payment for this study which
Commissioner Froude said has since been resolved and the Tigard Water District
agreed to pay the $2,600 for the study The Water District will pay for the study
and compliance measures needed, versus billing according to percentages of
ownership Mr Wegner continued by saying that the City would authorize a
contract with a consultant to complete.the study and payment will be made from
Water District funds Staff will take the recommendation from the study and
determine budget appropriately for completion

DATE May 1, 1997
SUBJECT Willamette River Raw Water Monitoring Program 1994-1996
I recently attended a presentation by Montgomery Watson on the final results of the Willamette River
Raw Water Morutoring Program conducted by Tualatin Valley Water District Attached are copies of
the Executive and Technical Summaries , A complete, detailed report is available in the Public Works
Director's office
• This program included regularly scheduled sampling for common drinking water quality parameters
As the Willamette continues to be considered as a possible regional drinking water source, the goal was
to more fully understand the treatment requirements of a future treatment facility
This will continue to be an on-going effort. Other agencies and utilities concerned with the Willamette
water quality will.need to continue to build on these findings
The Executive Summary states the study "did not reveal any water quality constituents of concern for
modern treatment methods, even during the extreme rainfall conditions of 1995/96 The Willamette
River appears to be a good source for development of high quality drinking water Further raw water
quality monitoring will strengthen these conclusions and add to the ability to efficiently and effectively
design a treatment process for this supply "

• EXECUTIVE SUMMARY
The Willamette River Raw Water Monitoring Program (WRRWMP) has characterized
Water quality in the Willamette River over a two-year,period, from April 1994 to July 1996
'Samples were collected at Wilsonville, Oregon and analyzed for the-physical, chemical, and
biological' parameters which are of interest for water treatment and public health This
sampling program adds 'to the record of water quality and pilot treatment data collected
during.a five-month filtration pilot study conducted for the Tualatin Valley Water District,
completed in March 1994 In addition to supplementing the database of water quality
information on the River, the WRRWMP data supports the basic processes recommended
for treatment of Willamette River water
The Willamette River Pilot Treatment Study (Montgomery Watson, 1994) recommended
pre-oxidation with ozone, followed by conventional filtration using a, granular activated
carbon-sand dual media. This treatment train provides multiple .barriers to; sediment and
bacteria, as well as to tastes and odors and organic chemicals should they be present in the
untreated supply It was fortunate that the two-year monitoring program included above-
average precipitation, in both years of sampling In particular, rainfall during the 1995-
1996 .penod was 50 percent above historical average rainfall amounts This presented an
opportunity to observe "worst-case" water quality conditions on the River, and to Judge the
ability of the recommended. treatment processes to handle these conditions Based on
observed River conditions, the recommended processes can be expected to produce a high-
quality drinking water, equal to or better than other sources in the region
Relative to other source waters in the U S , the Willamette River is a soft, low turbidity
• water with a low organic content All of these conditions are desirable for the production
of high-quality drinking water Observed water quality.conditions during the monitoring
period were comparable to other Willamette Basin. source waters, including the North
Santiam River (City of Salem) the Clackamas River (Clackamas Water District) and the
Tualatin River (Joint Water Conunission) In general water quality was stable during the
summer dry season average summer turbidity was low at 2 4 NTU Mayor parameters
particularly turbidity, TOC, and UV2S4 absorbance varied with river flow during the late
October to June rainy season
No water quality contairunants were observed at levels, which pose concerns about the
ability of the recommended 'treatment process to meet or exceed current and anticipated
drinking water standards Overall raw water bacteriological quality was good Out of a
total of 26 monthly samples, only two samples reported confirmed Giardia cysts at 1 6 and
13 cysts per 100 L No confirmed Cryptosporidium cysts were detected in.any sample
Samples were anayzed for a total of 160 regulated and unregulated synthetic organic
chemicals during the two-year monitoring period Only 6 compounds were detected out of
the 160 analyzed Of regulated compounds the herbicide atrazine and di-(2-
ethylhexyl)phthalate (DEHP) were detected at levels well below the State and federal
maximum contaminant levels Samples taken during the "first ,flush' storm of the raim
season did not yield significantly higher contaminant concentrations than those taken during
other storm events Although the detected chemicals were observed to be present at levels
well below treated water drinking standards the recommended treatment processes of
ozone and granular activated carbon filtration have been shown to be effective for the
removal of these chemicals from water
•
Willamette Ritter Raw Water Monitoring Program 1994 1990 page i
Final Report
An "earthy" odor was consistently detected in Willamette River water at levels that may be
noticeable to consumers Tastes and odors are routinely observed at the City of Corvallis, •
an upstream municipal water supply which also uses the mainstem of the Willamette River
"Earthy" odors are a common occurrence in surface water supplies around the world, and
are. usually due the presence of algae and their metabolites Oxidation with. ozone and
granular activated carbon adsorption are also effective barriers to these compounds
In summary, the WRRWMP did not reveal any water quality constituents of concern for
modern treatment methods, even during the extreme rainfall conditions of 1995-1996 The
Willamette River appears to be good source for development of high-quality drinking
water Further raw water quality monitoring will strengthen these conclusions and add to
the ability to efficiently and effectively design a treatment process for this supply

4/rkl
TECHNICAL SUMMARY
The Willamette River Raw Water Monitoring Program (WRRWMP) was designed to
charactenze water quality in the Willamette River via weekly, monthly, senu-annual, and
storm sampling of physical, chemical, and biological parameters The chief purpose of the
program was to provide a basis for understanding the treatment requirements of a future
dnnking water treatment facility The WRRWMP was a two year effort, the data presented
in this report spans a 26-month period from April 19, 1994 to June 30, 1996 The river is
sampled'at River Mile 41, in Wilsonville, Oregon
Measurable precipitation was regularly recorded at two NOAA Cooperative Weather
stations, each within 17 river miles of the Wilsonville sampling site from Apnl 1, 1994 to
June 30, 1996 The rainy season typically lasted from late October to June and comprised
95% of the total precipitation for the year; the dry season was June to October The two
years of the Willamette River Raw Water Monitoring Program (WRRWMP) experienced
above-average rainfall for the region Average precipitation for the region is approximately
43 inches per year Dunng the first year of the WRRWMP, about 48 inches of
precipitation fell, greater than 10% above average, during the second year, precipitation
increased to over 65 inches annually, an amount 50% above historical levels River gage
height near the Wilsonville sampling site and estimated river flow based upon this gage
height were stable in`the dry season and vaned widely during the rainy season Estimated
river flow for the period of the sampling program typically ranged from 9,000 cubic feet
per second (cfs) to '154,000 cfs (5 800 million gallons per day (MGD) to 100,000 MGD)
but spiked to approximately 357,000 cfs (232,000 MGD) during the flooding in February
1996
Several water quality parameters varied seasonally with precipitation and 'river flow
Turbidity UV254 absorbance, alkalinity and total and dissolved organic carbon
(TOC/DOC) were, relatively stable in the dry season and exhibited a wide range of values,
during the rainy season Turbidity', UV254 absorbance, and, TOC/DOC were moderately
correlated between each other and river flow:; lower values were recorded in the dry-season
and peak values were recorded in the rainy season Alkalinity appeared'to vary inversely
with river flow Weekly dry season turbidity averaged 2 4 NTU and varied from 1 6 to
5 6 NTU, average measured weekly-turbidity during the rainy season was 14 4 NTU and
the peak recorded turbidity was 193 NTU Weekly UV254 absorbance ranged from 0 050
cm-1 -to 0 237 cm-1 Typically, 90% of the weekly TOC was dissolved, weekly TOC
averaged 2 1 mg/L and ranged from 1 6 mg/L to 3 75 mg/L
Temperature and pH vaned on broad seasonal cycles, these water quality pararneters were
less affected by day-to-day changes in precipitation and river storage Temperature for the
period of the sampling program averaged 13-9°C and ranged from 5 0°C to 23 4°C For
the same period, pH averaged 7 3 and ranged from 7 0 to 7 6
Histoncal averages, measured at Newberg by the Oregon Department of Environmental
Quality (ODEQ), for turbidity, UV254 absorbance, alkalinity TOC/DOC pH and
temperature were consistent with the values recorded during the WRRWMP
Calcium and total hardness varied together from week to week Total hardness ranged
from 20 to 32 mg of CaCO3/L and averaged 24 6 mg of CaCOVL for the monitoring
Period Monthly ammonia-nitrogen vaned predominantly between 0 028 mg/L and 0 060
• mg/L and averaged 0 050 mg/L

Final Report
The bactenological quality of the water was good 84 of 89 samples (94%) for total
coliform bacteria were below the SWTR criteria of 100 colonies/100mL for unfiltered water
supplies All five exceedances occurred during precipitation events in the rainy season
Fecal coliform bacteria concentrations consistently exceeded the SWTR criteria of 20
colonies/100mL during the rainy season This limit was exceeded in from 10% to 30% of
the samples taken during the dry seasons
Additionally, bacteriological measures of water quality vaned slightly with river flow
Total coliform bacteria, fecal coliform .bacteria and heterotrophic plate count bacteria
exhibited a general trend for higher results during the rainy season Total coliform bacteria
and fecal coliform bacteria counts from Wilsonville were significantly lower than monthly
historical average,counts from Newberg collected and analyzed by ODEQ This difference
is most likely due to differences in the analytical methods used.
Weekly Flavor Profile Analysis of. Willamette River water yielded "earthy" as the
predominant odor "Earthy' was detected at an average intensity of 3, considered to be an
intensity that most people would notice The presence and intensity of the "earthy" odor
did not appear to vary seasonally "Fishy" and "woody" were also detected, though at a
lower intensity The "fishy odor was detected in the summer and is probably associated
with algal blooms occurring upstream. These results support the use of ozone and GAC
for taste and odor control
Monthly sampling for the protozoan cyst-stage of Giardin and Cryptosportdium was
performed Presumptive counts for Giardia ranged from less than 1 to 4.4 cysts/1001-
Confirmed Giardia cysts were reported in April 1995 at a concentration of 1 6 cysts/1001-
and in March 1996 at a concentration of 13 cysts/1001- Presumptive counts for
Cryptosporidium ranged from less than 1 to 44 oocysts/1001- No confirmed
Cryptosportdium oocysts,were.found in any of the 26 monthly samples Concentrations of0
Gtardta and Cryptosporidium cysts and oocysts in Willamette River water sampled at
Wilsonville are slightly lower and less variable than concentrations in samples taken
upstream in the Willamette Basin Over the time periods sampled, concentrations appear to
be higher than those found in Bull Run water, and no greater than those found in Cedar
River water; both protected Northwest watersheds
Storm event sampling was well-timed to catch the peak of river flow The four sampled
storm events adequately represented first-flush and mayor storm events for the 1994-95 and
1995-96 rainy season The high water in February of 1996 was not sampled due to
flooding of the intake pump Four semi-annual samples adequately represented low-flows
in the Willamette River at Wilsonville in the 1994 and 1995 dry seasons, as well as typical
high flows during December 1995
In storm and semi-annual sampling, 6 organic compounds were detected out of _160
regulated and unregulated compounds analyzed. Atrazine, di(2-ethylhexyl)phthalate
(DEHP), benzo(b)fluoranthene, benzo(k)fluoranthene, chrysene, and phenanthrene were
detected in the Willamette River at.levels slightly above their detection lirruts The herbicide
atrazine was detected in the three of eight samples which corresponded to the highest
sampled 'flows on the Willamette Atrazine and DEHP are compounds regulated by the
State of Oregon 'The concentration of atrazine detected was well below the MCL of 3
µg/1- DEHP was .detected in both storm samples at .levels considerably lower than the
MCL of 6 4g/L DEHP is commonly used in the manufacture of plastics
Overall, concentrations of the few detected organic compounds and metals were not
significantly greater during the first storm sample of the year compared to other samplmLr •
times This trend held for weekly-sampled flow-sensitive parameters such as turbidii%

Final Report
• UV254 absorbance, and coliform bactena concentrations as well only TOC appeared to be
at a maximum peak during the first storm of the rainy seasons sampled The occurrence of
notable concentrations of aluminum, atrazine and other sediment-associated compounds is
most likely due to sediment disturbance in the river bed This disturbance is associated
with storm event river flows-and was indicated by increased turbidity

MEMORANDUM
CITY OF TIGARD, OREGON
TO Ed Wegner
FROM Mike Miller OA
DATE April 29, 1997
SUBJECT Lead and Copper Update
Background
Since 1992, the Tigard Water District (now City of Tigard) conducted initial lead and copper testing
in accordance with US EPA regulations The test samples were taken from the customers tap
inside individual homes built between 1983 and 1985 Although the water in the distribution system
is well below the EPA action levels, the test results from the customers taps inside their homes did
exceed the action level at the 90th percentile The action levels are 0 015 milligrams per liter (mg/1)
for lead and 1 3 mg/I for copper The water in the distribution system is <0 001 mg/I for lead and
<0 01 mg/I for copper
• Since our water supplies are very soft, lead enters the water system of individual homes primarily
as a result of corrosion, or wearing away, of materials containing lead and copper in the household
plumbing These materials include lead-based solder (which was banned by 1986) to join copper
pipe, and brass and chrome plated brass fixtures
When water stands in plumbing systems containing lead for several hours or more, the lead may
dissolve into the homes drinking water This means that the first water drawn from a tap in the
morning, or later in the afternoon after returning from work or school, can contain fairly high levels of
lead
Under federal guidelines, the City of Tigard is required to have a program in place to minimize lead
in the drinking water by July 1, 1999 Under the guidelines our program is to consist of corrosion
control treatment, source water treatment and public education
Current Situation
Prior to this last summer, Tigard was purchasing approximately 88% of its water supply needs from
the City of Lake Oswego Under the Lead and Copper Rule, Lake Oswego is required to have its
treatment facilities in place by January 1, 1998 Basically we were going to wait and work jointly
with Lake Oswego on a corrosion control plan However this all changed when Lake Oswego could
not supply us any water on two separate occasions during the summer of 1996
Due to the water supply situation last summer, we are now purchasing approximately 70% of our
water supply from Bull Run Because we have significantly increased our purchases from Portland,
• Portland has included us in their joint corrosion control plan We greatly benefit from this because
r:
I
j • Portland is willing to modify the treatment of their water so that Tigard is in compliance with the
federal guidelines
In January 1997, the Portland Water Bureau began treating Bull Run water to control corrosion.
The treatment consists of adding 1-2 mg/I of sodium hydroxide as part of the water treatment
process The purpose of the treatment is raise the pH of Bull Run water Prior to treatment pH was
6 8, after adding sodium hydroxide the pH is ranging between 7.2 to 7 3 By raising the pH, Bull
Run water will become less aggressive Meaning that the likelihood of lead and copper leaching
from the home owners plumbing is greatly reduced.
Treating Bull Run water is one of the components of the City of Portland's Lead Hazard Reduction
Program As being a partner in this program with Portland, we will be able to comply with the
federal Lead and Copper Rule, as required by the US EPA.
The goal of Portland's Lead Hazard Reduction Program is to provide better public health protection
from lead exposure, at an equivalent or lower cost, than the extensive corrosion control treatment
that the federal Lead and copper Rule typically would require In addition to the pH adjustment,
Portland has also implemented a lead Hazard Reduction Program. The Portland Water Bureau
developed this program in partnership with the Oregon Health Division, health departments in
Multnomah, Washington and Clackamas counties, and the other water wholesale buyers of
Portland water This effort is part of the Clinton Administration initiative for Reinventing
Environmental Regulation --which allows regulatory flexibility in exchange for greater environmental
benefits
• Over the next few months we will be collecting pH and alkalinity samples from our Lake Oswego
connection on a biweekly schedule The reason for monitoring the pH and alkalinity of the Lake
Oswego supply is that we will still be purchasing a small portion of our total water supply from Lake
Oswego We are monitoring the water to see if it will have an adverse effect upon Portland's pH
enhancement.
We do not have to sample the connection points to our service area from Portland or Tualatin
Valley Water District, because Portland is already monitoring these supplies
During the week of June 2, 1997 we will be conducting the first round of joint lead and copper
monitoring at the customer taps, and the second round of water quality parameter monitoring in the
distribution system (first round water quality parameter monitoring was conducted during the week
of April 14, 1997) Our share of sample sites at the customer taps is proportional to our
consumption of Portland Water We are required to take a minimum of three (3) samples from
randomly selected customers within our service area that were part of the original test group in
1992
By participating in Portland's Lead Hazard Reduction Program we receive economies of scale, the
water samples are collected and analyzed in a consistent manner; and at the same laboratory The
results of which is a high level of quality control and a joint compliance package for the Lead and
Copper Rule
I will provide future updates as the program progresses
