We will be having our meeting on the 28th of September but will be taking no action on this matter. Sincerely, l 1 aatifer John Hat rger ,Chairman Tigard Water District For Immediate Release September 18, 1998 Contact: Liz Newton City of Tigard 503-639-4171 TIGARD, Oregon - City officials Friday renewed their commitment to an ongoing, comprehensive review of Tigard's future water supply options following the release of a limited-scope public opinion survey by the City of Wilsonville about its future water supply options. For months, Tigard officials have been meeting with area citizens to describe the community's long-term water needs, how it is being addressed, what the likely options are, and when a decision will be made. "We want our citizens to know all of the facts so they can express a thoughtful opinion on their future water supply. It is not fair to ask for people's opinion when you present them with very limited information, and then create the expectation that you will make a decision based on those findings. We've established a higher standard in Tigard," said Ed Wegner, Public Works Director. "We know that Tigard water users want high quality, safe and reliable water at a reasonable price that they can afford. To meet these standards, the Tigard City Council will make a comprehensive evaluation of two likely supply options. One, is an expected proposal from the City of Portland for service from its South Shore Wellfield-Bull Run, and a second is a proposal to build a state of the art water treatment plant on the Willamette River," Wegner said. The Tigard City Council is expected to receive both proposals in December, study them through a public involvement process and make a final supply decision by April. Currently without its own long-term water supply, Tigard purchases surplus water from the City of Portland thorugh a contract that will expire in 2007. "While our need is immediate, we are not making any hasty decisions based on incomplete information. We have established a rigorous process to evaluate the options, a program to listen to our citizens' opinions and make a decision. We believe this process has the very strong support of Tigard area water users because they recognize it is the responsible way to solve a complex issue,"Wegner said. Wegner said his response to the Wilsonville public opinion survey was based on his reaction to news reports, as he had not seen the actual survey. "Because this is a complex issue there is bound to be some confusion. Tigard has been criticized by some for favoring the Willamette option over a future supply from Portland. We had so much more information about the Willamette option than we had from ' ` - Portland at the time. Portland officials are now really hustling to give us the-level of cost, quality and reliability information that our City Council needs," Wegner said. J (A 4 s .,.

We have been in contact with Mark Knudson at Portland Water and they too have been receiving more calls than normal. Portland indicates that this is due to the fact that they have been taking water from a lower level (water column) in reservoir 1 in the Bull Run. Portland also indicates that this is a very "common phenomenon" for this time of year. That drawing water from these lower levels is necessary due to the ongoing drawdown of the reservoir. The color that we are seeing is typically a "yellowish" or weak tea, and is the result of naturally occurring dissolved organic matter that are more concentrated at the lower levels of the reservoir. The color, while an aesthetic concern, does not present any health concerns. We and Portland contiue to be well within standards for turbidity and bacteriological quality. Unfortunately, since Portland does not have a filtration plant, there is little that they can do about the problem. Portland continues to monitor the water quality at all of the levels of the reservoir and make adjustments as needed to get the best water quality available. This color should not be confused with the "leaf tea" color that is associated with the leaf drop in the Fall. This will occur later this Fall and is due rain, more than just the recent showers, leaching organics from fallen leaves. It looks like it will be a long Fall, at least for water quality from the Bull Run. Mike Mike MIller -- 1 -- Mon, 28 Sep 1998 17:57:45 Sep 22 G:\94\0310.410\A-MGD-YEAR.dwg • . !
