The Kitsap Public Health District's Water Pollution Identification & Correction (PIC) program protects public health and prevents fecal pollution in Kitsap County surface waters.
Health District staff sample dozens of streams and swimming beaches across the county for fecal bacteria, an indicator of fecal pollution caused by human or animal waste. Fecal pollution can carry viruses and harmful bacteria that make people sick.
We use water sampling results to notify the public of potential health risks, and to find and fix fecal pollution problems. This helps keep our streams, swimming beaches and shellfish beds safe and healthy for the public to enjoy.
