Water Quality

Lake Forest Park Water District staff & commissioners are committed to meeting the most stringent and most recent regulatory standards. At the same time we recognize most of our customer's long standing appreciation and desire for naturally pure, chemical free water, and we will do our best to meet this expectation. The District's customers are fortunate to have their own protected artesian & deep well sources which continues to produce high quality water, and has shown no signs of deterioration over several decades of use.

In-House Water analysis

Our water is even more closely monitored for harmful bacteria now that we have in-house bacteriological testing. We are using industry standard membrane filtration methods to determine if our water has become contaminated by coliform bacteria which are normally found only in the gut of warm blooded animals. This is the standard test that the Department of Health (DOH) requires of all water districts to ensure water safety. Specifically, based on our size, the DOH requires our district to obtain the results from 3 samples per month, which we will continue to have analyzed at a certified lab.

Our in-house sampling is for closer monitoring and engineering purposes and allows timely analysis (results in under 24 hours) while giving us savings in fuel expenses and lab fees. We are excited about this development and are sure that as our customers you will appreciate our committment to providing clean and naturally pure water!

Below are test results as required for compliance with State & Federal water quality assurance programs.

Consumer Confidence Reports (CCR)

This report provides information on the quality of your drinking water over the past year. We send this update to our customers each year. If you have any questions or comments please call Lake Forest Park Water District at (206) 365-3211.

The U.S. Environmental Protection Agency (EPA) requires water suppliers to put annual drinking water quality reports into the hands of their customers. These consumer confidence reports, which EPA developed in consultation with water suppliers, environmental groups, and the states, will enable Americans to make practical, knowledgeable decisions about their health and their environment.
