Water Quality
Water Quality Standards

The United States Environmental Protection Agency (EPA) and State Water Resources Control Board-Division of Drinking Water are responsible for setting water quality standards and regulations. Providing the highest quality of water to our customers is essential.

District staff routinely sample for water quality and compliance with these standards and regulations. The District has always met these standards.


Consumer Confidence Reports

We are pleased to provide you with access to current and previous years' Consumer Confidence Reports. We want to keep you informed about the quality of your drinking water, detected contaminants, and possible health risks. We believe these regulations are very important, and we make every effort to present this detailed information in a simplified manner.


 
Water Analysis Schedule

2015 Water Analysis Schedule


Entrained Air

If your tap water seems cloudy, hazy, or has a slightly “milky” appearance, you are probably experiencing a condition known as “entrained air.” This condition is harmless and is almost always caused by air in the water. One of the many properties of water is its ability to dissolve gases – including air. Sometimes the air comes back out of the water in the form of many tiny bubbles, giving the water a “milky” appearance.

If your tap water is “milky” and you want to confirm whether or not you are experiencing entrained air, rinse out a clear glass twice and then fill it with cold tap water. After a few moments, the water should begin to clear from the bottom of the glass to the top as the bubbles rise to the surface. This is a completely natural occurrence and is harmless.

If your water does not clear after 5 minutes, please call our office and we will be happy to assist you.


Flushing

Flushing is required by the State Water Resources Control Board – Division of Drinking Water, and improves water quality by running water at high speeds to remove sediment that builds up at the bottom of the water main over time. Here are a few reasons why flushing is beneficial:

  • Reduces damage from corrosion and eliminates bacteria growth by pushing water through pipelines at high speed
  • Removes sediment and mineral deposits that can affect water taste and odor
  • Ensures that hydrants and valves will work properly to better respond during emergencies 

Visit our Flushing Program page for more information.
