To Whom it May Concern:
.In conformance.with the requirements of OAR 333-061-0040, the results-of our Lead and Copper
Rule compliance monitoring for the first peripd of'1999 are attached. These results are presented
as a technical memorandum.
Monitoring was conducted.as described in our joint monitoring proposal submitted May 14, 1997
and approved by Oregon Health Division in their letter of June 23, 1997. As described in the
. plan, all water systems using Bull Run water as their sole or major source of supply are
considered as a single,large system for compliance with Lead and Copper Rule monitoring
requirements.
.In summary the monitoring included collection of 126 samples from Tier I homes distributed
throughout_the participating systems' service areas. Samples were collected between May 12
and June 6, 1999. As detailed in.the attached report,the 90th percentile values for the Joint.Plan
data are.as follows:
Lead 0.020 mg/L
Copper 0.64 mg/L
Also, presented are results from the distribution system water quality parameters. In summary,
the system pH ranged from 7.1 to 8.3. Distribution system results are slightly higher and more
consistent than in the previous distribution monitoring periods.
In June of 1998 OHD set entry point water quality parameters for the Bull Run system.
Although these data are reported monthly in a separate report, it should be noted that excellent
treatment control has been maintained and control has improved since the beginning of corrosion
treatment.
Nonetheless the home results for lead continued to exceeded the action level for the second time
after implementation of corrosion control treatment
An F. aua ! Oni) oriuniiv Z ni1) l c
Portland previously presented an action plan in response to the previous exceedence. This plan is
updated and reported on below.
1. Public Education will again be conducted according to OAR 333-061-0036. By July 30,
Portland will notify the media and specific members of the community as detailed in this section
of thexule. Portland will do media notification for the joint monitoring participants. When the
Public Education is accomplished, a report will be made to OHD.
2. Public information and education continue to be conducted through the XLC Program.
3. Additional research was completed at the Tier.One homes. A copy of the technical report is
included.
4. Portland.has reviewed the system corrosion chemistry and has gradually increased the pH
target at the entry point at the Lusted Hill Treatment Plant.
Please contact me at 823-7127 if you have any questions or concerns regarding this information.
Sincerely,
Steve Schenk, P.E.

TECHNICAL MEMORANDUM
DATE: July 9, 1.999
TO: Steve Schenk, P.E '� f
FROM: Kathy Casson and Khanh_Co
SUBJECT: - Lead and Copper Monitoring Results
Objectives
Thi's technical memorandum summarizes the monitoring required by the'Lead and Copper Rule.
Results for the May 1.999 lead and copper tap sampling and distribution water quality parameters
are presented.' Source water-°results for April 1999 are included.
Corrosion Control'Treatment
From January 1 through,-May 27, 1999, the sodium hydroxide dose rate was adjusted asneeded
to achieve a target PH of 7.55 to 7.65 pH units at the outlet of the Lusted facility. As of May 28,
1999 the°pH target was changed to 7.75 to 7'.85.The sodium hydroxide dose,ranged from
approximately 2 to 4---mg/L.
Monitoring Plan
The monitoring during the first six-month period of 1999:was conducted according:to the
proposed joint monitoring plan submitted May 14, 1997,and approved by Oregon Health
Division in their letter of June 23, 1997._ As described in the plan, all water systems using Bull
Run water as their sole or major source of supply would tie considered as a single large system of
complying with Lead and Copper Rule monitoring requirements, The following systems
submitted the Joint Monitoring Plan:
Burlington Water District
The City-of Gresham
City of Tigard
Lorna Water Company
Powell Valley Road Water District '
Pleasant Horne Water District
The City of Portland
Raleigh Water District
Rockwood PUD

Tap Monitoring for Lead and Copper
Table 1 (below) summarizes the sampling required by the Joint Monitoring Plan and the actual
total number of home tap samples collected in the second six-month period of 1999. Extra
samples were collected to provide a contingency in the event individual homeowners withdraw
from the program over time.

All samples were collected from Tier I homes sampled in 1992. All Portland Water Bureau
homes sampled in November except three were resampled this time. Two homes from"the
Portland Water.Bureau Tier One pool(were added. Tualatin Valley Water-District(TVWD) .
replaced a home who declined to participate in November 1998. Powell Valley Road Water
District(PVRWD) replaced.a home who.declined to.participate this,time. Both replacement
homes were selected randomly from tier one homes sampled in 1992. The.PVRWD replacement.
home differed from the home it replacedin being served by 1:00%o Bull Run'Water rather than a
blend of Bull Run and Wells 3 and:4. Finally Portland Water Bureau discovered that a home that
had been in its sampling pool was really servedby Powell Valley.Road.'Water District., This
home(22) is still being sampled but is attributed to PVRWD. Otherwise, participating utilities
sampled the same homes in May 1999 as were-sampled in November 1998.
All home tap samples were collected between May .12 and June 6, 1999. 'Directions provided.to
customers:specified first draw one-liter.samples drawn from.the cold water kitchen tap, unless
there was an inline filter on the kitchen tap that could not be bypassed. Complete instructions are •
shown in Appendix 1. All but seven samples were collected from the kitchen tap. Six were
2
collected from.bath taps. One sample collected by a Rockwood resident did not have the sample
location checked and the residents have not been able to be contacted.
Analyses were performed by the Portland Water Bureau,Water Quality Laboratory. The 90th
percentile lead and copper values were determined asdescribed in 40 CFR 141.80.
Water Quality Parameters.in Distribution System
Tap samples were collected at twenty-eight sites throughout the area served by Bull Run water as
shown in the Table 2 below.

These sites were sampled twice during the first six months of 1999. Samples were collected
during-the week of February 842 and the Week of May 17 -21. All samples were analyzed.for
pH in the field Wing-pH meters equipped with electrodes suitable for water of.low ionic strength.
Although not.required, we continued to measure alkalinity to better understand:its effect on pH
stability in the,system. Alkalinity samples were analyzed by the Portland Water Bureau,Water
Quality Laboratory• .
Results
Tap Monitoring for Lead and Copper
The lead and copper results from tap sampling.at the 126 tier I homes sampled in May 1999
according the Joint Monitoring Plan are shown graphically in Figures 1 and 2. The lead and
copper raw results are shown in Table 3a and 3b and briefly summarized below. Addresses for.
the 126 homes are shown in Appendix 2.
The lead 90'hpercentile results exceeded the action level for this round of monitoring. The
copper 90`'' percentile results are below the action level for-this round of monitoring. The lead
901h percentile-result was 0.020 mg/L (action level=0.015 mg/L); the'copper 90'percentile result
obtained from interpolating between rank was 0.64 mg/L (action,level=1.3 mg/L).

Conclusions .
Based on the data submitted, the following conclusions are offered:
• For the five consecutive six month monitoring periods following the installation of corrosion
treatment the 90'percentile copper was below the copper action level.
• In May 1999,the 90`x'percentile value for lead of 20 µg/L exceeded the lead action level.
• Although the copper level after treatment has been very stable, lead levels have increased
from 12 to 20-µg/L in the two and a half years since corrosion treatment was implemented
• pH adjustment of the Bull Run Supply is effective in maintaining a pH of approximately 7.0
to 8.0 in the service.area.

Columbia-Willamette Water Conservation Coalition
1998 — 1999 Annual Report
The Columbia-Willamette Water Conservation Coalition has completed its sixth year
working together to further the role of efficient water use through out-the region with the
primary goal of providing consistent conservation messages. There are currently 18"'
member agencies in,the Coalition representing cities in Multnomah, Clackamas,
Washington, and'Yamhill counties. Our newest members are the City of Forest Grove,
and West Slope Water District. Metro decided_not to be a:,member this year due.to
funding issues.
The benefits'of workirig'together continue in our ability to leverage limited programmatic
resources,.in suppprting information networking and coordination between agencies, and
in our ability to develop.regionally based conservation programs and projects�which
support peak season use.reductions.
I would like to provide,you with a brief.summary of the Coalition accomplishments this
past year.
Community Events and Outreach
• Roar Faire at the Zoo The Coalition sponsored a low water•use planting project
for kids and adults at this event last summer.-
0
ummer:9 Yard Garden.&-Patio Show/Home & Garden Show —The Coalition continued to
staff informational booths at these shows to provide information on water
conservation and water wise landscaping.
• Landscape Workshops — The Coalition sponsored and co-sponsored 13 water wise
landscaping workshops on design and maintenance of low water use landscapes with
Drake's 7 Dees, Dennis"7 Dees, and Max and.Hi.ldy's
• Water Wise Plant.Labeling Pilot Project— The Coalition has been working with
local nurseries to develop.a water wise plant labeling program to help customers
identify low water use plants. This project is on-going,
a Summer'Multi-Media Campaign - The Coalition's summer campaign includes TV,
radio and print advertising. TV and radio ads included short, general tips about,wise
water use outdoors. Print.ads used during the summer of 1998 and spring of 1999
included articles with specific information on a variety of irrigation subjects.

Work Related to Regional Water Supply Plan
• Landscape Guidelines —The:Coalition hired Cascadia Consulting to provide
research on landscape guidelines/ordinances both regionally and in other states and
provide potential incentive/regulatory strategies. .In September, an intensive
workshop was conducted with stakeholders to begin the process of discussing
potential landscape guidelines herein the Portland Metro region.
• Measuring and Tracking Conservation Programs — Working with Consortium
Staff and the consultant team of Maddaus Water Management and,the Weber Group,
Coalition staff developed a water conservation baseline survey, which was published
in January 1999. A final report on measuring and tracking of conservation in the
region was finished in April. Coalition staff continues to work with Consortium staff
to implement the demand tracking methodology region-wide and is further working
on actual conservation program evaluation.
Industrial/Commercial/Institutional
Cooling Tower.B.00klet—The Coalition has been working with Portland's$IG
Program to produce a booklet on Cooling Water Efficiency for commercial and •
industrial water users. The Coalition plans to help BIG sponsor cooling tower
workshops through the region in FY 99-00.
Youth Education
• Project.WET Workshop —The Coalition sponsored a Project WET workshop to 30
teachers in the Portland,Metro area, with the.purpose of helping teachers understand
the importance of water issues and by giving them the tools to be able to teach about
water in their classrooms. The workshops focus on water supply and conservation in
the Portland region.
• Clean Water Festival —The Coalition sponsored the stage shows, staffed the

• Conserv '99—Conservation staff from 9 member utilities attended the Consery'99
Conference in Monterey, California earlier this year, and it was evident after hearing
about conservation programs across the nation that, as a region , we already
implement many of the programs that were being discussed through our regional
partnerships.
This year's budget decreased from $193,000 in FY 1998-99 to $184;015 due mainly to .
the difference in Metio's membership cost share. Attached is the Coalitions budget.
allocations for FY 1999-20.00.

Scope of Services
1. Update Rate Model
The City will update the following information and provide it to CH2M HILL:
• Current water meters by meter size and customer class.
• Bi-monthly water sales by customer class and rate block (for single family)for the most recent
year..
• Actual 1997/98, budgeted (or estimated) 1998/99, and budgeted 1999/0.0 (if available) O&M
costs by line item.
• 5-year capital improvement plans for each scenario to be analyzed. The CIP`should include the
.estimated capital expenses,for each year, and the percent of,each project that.is associated with
meeting the demands of new customers.
• Fixed asset-schedule,as of 12/3'1/98, including accumulated depreciation and contributions.
Existing debt service schedule(s)
Cur-rent rate and.SDC schedules
®. Current and projected(under each scenario)water system design capacities -.
O Water fund-summaries (e.g., fund balances,revenues, and expenses for,operating, capital, and
• SDC funds)
CH2M HILL will review,the data,and use it to:update the,rate model. CH2M HILL will,modify the
existing water rate model io.calculate rates on an annual cost of service basis. The updated model
will accurately reflect the.;annual impacts on water`rates of;financing and operating planned capital
improvements. 'The'improved model will have the flexibility to be updatedon an annual basis by
City staff.
2. Conduct Scenario Analysis
CH2M HILL will develop three alternative rate schedules based on the capital improvement
alternatives developed by the City. For each scenario, CH2M HILL will work with the City to
evaluate capital financing alternatives (e.g., debt,current revenues, and SDCs), refine cost
allocations (as necessary), and develop a five-year schedule of rates and SDCs.
3. Prepare Draft,and,Final Reports
CH2M HILL will prepare a draft report that: 1) presents existing rates, 2) describes the assumptions
and projected costs associated with each water supply option analyzed, and 3) summarizes the
impacts on rates of each scenario. Following receipt of comments on the draft, CH2M HILL will
prepare.a final report.

4. Attend Meetings and Presentations-
CH2M HILL will attend one interim meeting with City staff to discuss preliminary results and refine
the analysis. CH2M HILL will also attend two meetings with the City Council, and/or other
interestedparties to discuss the analysis andpresent findings.
5. Refine Model Format and Features
CH2M HILL will restructure the current rate model to improve flexibility,allow for annual rate
analyses, and facilitate scenario analysis. In addition, CH2M HILL will complete macros for
printing tables within each sheet of the model.
