The National Academy of Science/National Research Council (NAS/NRC) gives a suggested no adverse response level (SNARL) for aldicarb in drinking water of 7 ppb (22). The USA Environmental Protection Agency (EPA) has recommended a "Health advisory level of 10 ppb. The California Department of Health Services has adopted EPA s limit as an action level (24). 

The US National Pesticide Survey, which was organized by the US Envirorunental Protection Agency (US-EPA), compiled a list of compounds based on the amoimt used (>7000 tons), water solubility (>30 mg/L), and hydrolysis half-life (>25 weeks) [23,24]. During the National Pesticide Survey (NPS), 1349 drinking water wells were sampled and analyzed for 101 pesticides, 25 pesticide transformation products (TPs) and nitrate, with a total of 127 analytes. The list also included the chromatographic protocol of the EPA employed in the NPS. The Office of Water of US-EPA has established drinking water regulations and health advisory levels for individual pesticides [25].
