Boundaries and Grid Cells of the North American, South American, and Cosumnes Study Areas for the Sacramento Metropolitan Shallow Aquifer Study Unit
The U.S. Geological Survey collected groundwater samples from 49 wells used for domestic and small system drinking water supplies in Amador, Placer, Sutter, and Sacramento counties, California in 2017. The sites were sampled for the Sacramento Metropolitan (SacMetro) Shallow Aquifer Study Unit 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 for domestic and small system drinking water supplies. Domestic and small-system wells are commonly screened at shallower depths than public-supply wells. The SacMetro study unit consisted of three “study areas” corresponding to three California Department of Water Resources groundwater subbasins: the North American and South American subbasins of the Sacramento Valley groundwater basin, and the Cosumnes subbasin of the San Joaquin Valley groundwater basin (California Department of Water Resources, 2016). Each subbasin was considered a unique "study area". The three study areas collectively define the extent of the SacMetro study unit. Wells in the SacMetro study unit were in alluvial aquifers composed of sediments derived from the Sierra Nevada Mountains east of the study unit. This dataset identifies the boundaries and grid cells for the three study areas of the SacMetro Shallow Aquifer Study Unit.
