Sucralose Concentrations in Groundwater in California's Sacramento Valley Shallow Aquifer System
This data release comprises a set of environmental sucralose occurrence data in the Sacramento area. Groundwater samples were collected throughout the Sacramento Valley as part of the California Groundwater Ambient Monitoring and Assessment Program Priority Basin Project study in the Sacramento area. These water samples were analyzed for sucralose by chemical derivatization followed by gas chromat
Delineation of spatial extent, depth, thickness, and potential volume of aquifers used for domestic and public water-supply in the Central Valley, California
Identification of the groundwater resources used for drinking-water supplies is essential for the design of strategies to manage those resources. In this study, the spatial extent, depths, thicknesses, and volumes of groundwater aquifers used for domestic and public drinking-water supply were estimated from locations and well-construction data from 11,725 domestic-supply wells and 2,376 public-sup
Quantification of sucralose in groundwater well drinking water by silylation derivatization and gas chromatography-mass spectrometry
Sucralose is an increasingly popular artificial sweetener and has been found in the environment in groundwater, surface water, and wastewater treatment plant effluent. Its chemical properties make it strongly recalcitrant in the environment and it has been used as a conservative tracer of human wastewater in recent years. Most current methods of sucralose analysis use high performance liquid chrom
Critical aquifer overdraft accelerates degradation of groundwater quality in California’s Central Valley during drought
Drought-induced pumpage has precipitated dramatic groundwater-level declines in California’s Central Valley over the past 30 years, but the impacts of aquifer overdraft on water quality are poorly understood. This study coupled over 160,000 measurements of nitrate from ∼6,000 public-supply wells with a 30-year reconstruction of groundwater levels throughout the Central Valley to evaluate dynamic r
