Summary

These datasets are one component of the multistressor studies conducted in Midwest streams in 2013 (MSQA) and in Southeast streams in 2014 (SESQA) by the U.S. Geological Survey National Water Quality Assessment Project. High-frequency small-volume autosamplers were deployed at 7 sites each in MSQA and SESQA that collected daily and weekly composite water samples, which were analyzed for 225 pesticides and pesticide degradates. Five of the MSQA autosampler sites were in agricultural watersheds and two in urban watersheds, whereas all seven SESQA autosampler sites were in urban watersheds. The daily and weekly composite samples were compared with results from traditional discrete water samples collected weekly at the sites. Mixtures [...]

Purpose

The objectives of this study were 1) to compare pesticide occurrence as indicated by daily composite sampling to that indicated by weekly composite and weekly discrete sampling, and 2) to compare potential acute invertebrate toxicity, as evaluated by comparison to established toxicity benchmarks and thresholds, determined from daily composite samples to that determined from weekly composite and discrete samples.
