Renton has been recognized as a Groundwater Guardian Community by the National Groundwater Foundation for the last four years. Water Quality and Maintenance Teams. The City Water Quality and Water Maintenance staff regularly monitors the quality of our water supply. Field and laboratory analyses include tests for bacteria, as well as chemical, physical, and radiological indicators. We test for over 120 compounds to make sure our drinking water is safe.
Most people give little thought to the water that comes out of their tap.
Our drinking water comes from wells and springs. As our water travels through the ground to the wells, it can dissolve naturally occurring minerals as well as substances from human activity. Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. Some people may be more vulnerable to contaminants in drinking water than the general population.
