Summary

Reported atrazine, carbaryl, chlorpyrifos, and fipronil concentrations for selected U.S. Geological Survey pesticide sampling sites were downloaded from the U.S. Geological Survey National Water Information System (NWIS) and modified for input into the SEAWAVE-QEX model. Modifications included identification of appropriate censoring limits to use for samples in which the pesticides were not detected, rounding reported concentrations to a consistent level of precision, and adjusting reported concentrations to correct for temporal trends in laboratory recovery rates.

Purpose

The original (non-modified) pesticide concentration data were reported by the U. S. Geological Survey, National Water Quality Assessment (NAWQA) Project, for a variety of NAWQA objectives. Modifications to the original pesticide concentration data were required to make them appropriate for input to the SEAWAVE-QEX model, which can be used to simulate daily pesticide concentrations and estimate concentration extremes, such as the annual maximum concentration.
