Service Description: This map displays pesticide concentration data for three priority pesticides: permethrin, bifenthrin, and fipronil (and three of fipronil’s toxic degradates). These pesticides were listed as the top three priorities for urban areas, according to the Department of Pesticide Regulation’s (DPR) surface water prioritization model, which accounts for prevalence, toxicity, and reported use. The markers on the map are colored red or yellow if a pesticide at that monitoring station has at some point exceeded a USEPA Aquatic Life Benchmark. These benchmarks indicate the concentration above which a pesticide is expected to cause toxic effects in aquatic organisms. Markers are red if the exceedance occurred in an urban area, and yellow if it occurred outside of an urban area. The map uses monitoring data from 2009-2015 from DPR’s Surface Water Database, which includes data from a wide variety of environmental monitoring studies, including data pulled from the Water Boards’ California Environmental Data Exchange Network (CEDEN).
