Summary

Dissolved pesticides were measured in weekly water samples from 482 wadeable streams in five regions of the United States during 2013-2017, as part of the U.S. Geological Survey's (USGS) Regional Stream Quality Assessment (RSQA). One study was conducted each year, starting with the Midwest (2013), followed by the Southeast Piedmont (2014), Pacific Northwest (2015), Northeast (2016), and Central California Coast (2017). Within each region, 77-100 streams were sampled over 6-14 weeks, followed by ecological surveys of fish, invertebrate and fish communities. The first study (Midwest) is an agricultural-gradient study, where the majority of sites were located along a gradient from undeveloped to 100% agricultural land within the watershed, [...]

Purpose

This Data Release contains pesticide concentrations in weekly water samples from five regional studies conducted by the Regional Stream-Quality Assessment (RSQA) Project. The pesticide data in this Data Release represent one component of the RSQA studies, which are multistressor studies conducted by the USGS National Water Quality Assessment Project, National Water Quality Program. The purpose of the data collection was to characterize mixtures of currently used pesticides and their degradates in streams within each of the five regions; to screen these mixtures for potential aquatic toxicity by using a combination of aquatic-life benchmark comparisons and the Pesticide Toxicity Index; and to generate pesticide indicators for use as explanatory variables in ecological models.
