Monte Rio Beach Remains Closed, Bacterial Testing Results Still Elevated

Santa Rosa, CA  –  July 7, 2017  –  Follow-up testing of samples taken from Monte Rio Beach continue to show elevated levels of coliform bacteria. The beach remains closed and signs advising the public to avoid swimming, wading or water contact remain posted in accordance with state guidelines.

DHS analyzed samples collected on Thursday, July 6th and received results today. Test results for total coliform was 10,462 organisms per 100 ml and E. coli results was 110 organisms per 100 ml. State guidelines and DHS protocol specify that any level above 10,000 organisms per 100 ml for total coliform or 235 organism per 100 ml for E. coli require posting of signage. 

Coliforms are bacteria that live in the intestinal tracts of warm-blooded animals, including humans, and therefore indicate possible contamination of water by fecal waste. At significant levels this bacteria could indicate that other disease-causing agents are present. Additionally, some coliform bacteria are pathogens and at certain levels can sicken swimmers and others who use the river. 

In addition to not swimming at the Monte Rio beach until further notice, DHS recommends the following healthy water habits:

  • Do not drink river water. Do not cook or wash dishes with river water.
  • Wash yourself and your family, including any pets, with clean water after river play.
  • Bring fresh water for your dog and do not let them drink river water.
  • If you have concerns regarding your family or pet's health, contact your healthcare provider or veterinarian.
