U.S. Geological Survey Circular 1291
Appendix 3. Water-quality benchmarks for pesticide compounds analyzed in NAWQA samples
Appendix 3D. References—Appendix 3
IMPORTANT NOTE: The benchmark values in Appendix 3 are the specific values used to analyze pesticide data in this circular. They were up-to-date when this circular was published (March 2006), but they do not represent the current benchmark values for the pesticides listed. For current benchmark values, readers should consult the original sources for each type of benchmark (see http://water.usgs.gov/nawqa/pnsp/source/).
