First Flush Water Quality Results 2016

Water quality results are in for 2016 stormwater runoff in the Midcoast and HMB.  Stormwater runoff carries pollutants that have built up across the landscape into creeks, storm drains, and the ocean. First Flush is a program of the Monterey Bay National Marine Sanctuary that monitors runoff from the first significant storm of the season which flushes accumulated pollutants from sources such as brake dust, car emissions, animal waste, detergents, pesticides and fertilizers, and many chemicals found around homes and businesses.  San Mateo County Resource Conservation District, with local partners and volunteers, conducts the program in coastal San Mateo County.
