ABSTRACT
The California Groundwater Ambient Monitoring and Assessment Program Priority Basin Project (GAMA-PBP) submitted 2,994 samples in 2004-2018 to the USGS National Water Quality Laboratory (NWQL) for analysis of pesticide constituents on NWQL schedules 2003, 2032, or 2033, and 840 samples in 2004-2011 for analysis of pesticide constituents on NWQL schedule 2060. Fram and Stork (2019) describe the GAMA-PBP data quality objectives for pesticide constituents and present a 5-step protocol for review and quality-control censoring of data from these NWQL schedules. This data release presents the original and final values for the 1,056 results censored by Fram and Stork (2019) and the entire final dataset for pesticide constituents on NWQL schedules 2003, 2032, 2033, or 2060 in GAMA-PBP samples collected in 2004-2018.
