Pharmaceutical Data from the California Groundwater Ambient Monitoring and Assessment Priority Basin Project (GAMA-PBP) Domestic Well Groundwater Quality Studies, 2014 - 2021
The U.S. Geological Survey collected groundwater samples from 537 domestic wells for pharmaceutical compounds between 2014 and 2021 from 9 different study units. These wells were sampled as part of the California State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project’s assessment of the quality of groundwater resources used...
