Background:
| The Napa River and its tributaries are listed as impaired by pathogens. The listing was made in response to observations of elevated fecal bacteria in the river. These bacteria indicate the presence of fecal contamination and attendant health risk to recreational users of the river from water-borne pathogens. Potential pathogen sources in the watershed include municipal stormwater, septic systems, sewer line leakage, pet waste, and livestock. The Napa River Pathogen TMDL will examine this water quality problem, identify pollutant sources, and specify actions to create solutions. |
