MONITORING REQUIREMENTS NOT MET FOR USFS Lost Claim, USFS 

Sweetwater, USFS Cherry Valley Campground, Groveland Ranger Station

Our water system failed to monitor as required for drinking water standards during the past year and, therefore, was in violation of the regulations.  Even though this failure was not an emergency, as our customers, you have a right to know what you should do, what happened, and what we did to correct this situation.

We are required to monitor your drinking water for total coliform bacteria on a regular basis. Results of regular monitoring are an indicator of whether or not your drinking water meets health standards. Water systems send their drinking water samples to a laboratory for regulatory testing. In April and May 2025 we were unaware that the laboratory’s accreditation for bacteria testing expired on March 31, 2025. 

Bacteriological water samples were collected and analyzed by the laboratory after its accreditation had expired and therefore, the State Water Resources Control Board, Division of Drinking Water did not accept the results for regulatory compliance in April and May 2025. 

What should I do? 

x    There is nothing you need to do at this time. x    If you have health issues concerning the consumption of this water, you may wish to consult your doctor. 

What happened? What is being done? 

We are using an ELAP accredited lab to collect and/or analyze samples used for bacteriological monitoring compliance. 

For more information, please contact Nicole Thompson, Civil Engineer, Nicole.Thompson@usda.gov 

Please share this information with all the other people who drink this water, especially those who may not have received this notice directly.
