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.

R 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 The City of Tualatin A Pi F. ounl nnuriuniI v in 1) r Tualatin Valley Water District Valley View Water District West Slope Water District 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. Table I. Tap Sampling for the Joint Monitoring Plan, May 1999.

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. Table 2.

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). • 3 • Figure 1.

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. 10 Appendix 1.

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. 1120 SW 51h Avenue, 5th Roor, Porr(an c. 0;4'7 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 Teachers Resource Center and presented,two classroom presentations at the Sixth Annual.Clean Water Festival which takes place each:March. • Youth Education Conservation Kits —.The Youth Education workgroup offered each member.agency the opportunity to receive,a water audit kit to use'for localyouth education efforts. • Where's Rosie?"- The water conservation puppet show "Where Rosie?" that was developed by the Coalition a number of.years ago will,now be shown on Metro area cable access.channels. Training • Training (United Pipe, Clackamas Community College, George Austin) — Coalition training provides member agencies with the opportunities to gain more technical information on irrigation issues and organizational skills such as project management: • 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.

Attachment A 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. City of Tigard -' i 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.
