Sources of Beachwater Pollution

Most beach closings and advisories are issued because beachwater monitoring has detected bacteria that indicate the presence of pathogens -- microscopic organisms from human and animal wastes that pose a threat to human health. The key known contributors of these contaminants are stormwater runoff, untreated or partially treated discharges from sewage treatment systems, discharges from sanitary sewers and septic systems, and wildlife.
