Before Starting - Preparation and Guidelines for Accurate Sampling
From a sink that you use often, run cold water until you feel a change in the temperature. It can take up to five minutes and will get noticeably cooler. This ensures that you are testing water from the main line and not the water in your house.
Collect samples in clean glass bottles. If your bottle is scratched or damaged, please contact us so we can send out a new one. Scratches may cause inaccurate results. To avoid scratching the bottle, please use the Kimwipes provided. Using a papertowel or other cloth to clean or dry the bottle can scratch it.
Air Bubbles - After filling up the sample bottle, put the cap on tightly. If there appear to be bubbles (pockets of air) in the sample bottle, turn the sample bottle upside down and then back upright and the air bubbles should be gone.
Recording and Reporting Procedures
If the test is out of the optimal range, run the water for an additional five minutes and retest.
If the test is still out of range, please report your findings immediately by calling Customer Service at (866) 357-8783.
Record the results on the Daily Customer Chlorination Report Form.
Email your report to PUDCustomerService@ThurstonPUD.org by the 5th of the following month.
