In an attempt to better determine whether the detection of a pesticide in drinking water (or its source waters) indicates a potential human health risk, the Agency has tabulated benchmarks for acute (one-day) exposures for the most sensitive populations (including children) and also chronic (lifetime) exposures for the general population. These non-cancer HHBP values have been calculated by the US EPA for 352 currently registered pesticides that may be found in surface or ground water sources of drinking water. They are based on acute and chronic oral reference doses (RfDs) previously determined during the EPA’s pesticide registration process (a link to each source document is provided on the website). The Agency intends to add human health benchmarks for pesticides in drinking water based on cancer effects to this table in the future.
