Book Status and Understanding of Groundwater Quality in the South Coast Range Coastal Study Unit 2008

Download or read book Status and Understanding of Groundwater Quality in the South Coast Range Coastal Study Unit 2008 written by Carmen A. Burton and published by CreateSpace. This book was released on 2014-08-01 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater quality in the approximately 653-square-mile (1,691-square-kilometer) South Coast Interior Basins (SCI) study unit was investigated as part of the Priority Basin Project of the Groundwater Ambient Monitoring and Assessment (GAMA) Program. The South Coast Interior Basins study unit contains eight priority groundwater basins grouped into three study areas, Livermore, Gilroy, and Cuyama, in the Southern Coast Ranges hydrogeologic province. The GAMA Priority Basin Project is being conducted by the California State Water Resources Control Board in collaboration with the U.S. Geological Survey (USGS) and the Lawrence Livermore National Laboratory. The GAMA South Coast Interior Basins study was designed to provide a spatially unbiased assessment of untreated (raw) groundwater quality within the primary aquifer system, as well as a statistically consistent basis for comparing water quality between basins. The assessment was based on water-quality and ancillary data collected by the USGS from 50 wells in 2008 and on water-quality data from the California Department of Public Health (CDPH) database. The primary aquifer system was defined by the depth intervals of the wells listed in the CDPH database for the SCI study unit. The quality of groundwater in the primary aquifer system may be different from that in the shallower or deeper water-bearing zones; shallow groundwater may be more vulnerable to surficial contamination. The first component of this study, the status of the current quality of the groundwater resource, was assessed by using data from samples analyzed for volatile organic compounds (VOCs), pesticides, and naturally occurring inorganic constituents, such as trace elements and minor ions. This status assessment is intended to characterize the quality of groundwater resources within the primary aquifer system of the SCI study unit, not the treated drinking water delivered to consumers by water purveyors. Relative-concentrations (sample concentration divided by the health- or aesthetic-based benchmark concentration) were used for evaluating groundwater quality for those constituents that have Federal or California regulatory or non-regulatory benchmarks for drinking-water quality. A relative-concentration greater than 1.0 indicates a concentration greater than a benchmark, and a relative-concentration less than or equal to 1.0 indicates a concentration equal to or less than a benchmark. Relative-concentrations of organic constituents and special-interest constituents were classified as "high" (relative-concentration greater than 1.0), "moderate" (relative-concentration greater than 0.1 and less than or equal to 1.0), or "low" (relative-concentration less than or equal to 0.1). Relative-concentrations of inorganic constituents were classified as "high" (relative-concentration greater than 1.0), "moderate" (relative-concentration greater than 0.5 and less than or equal to 1.0), or "low" (relative-concentration less than or equal to 0.5).

Book Status and Understanding of Groundwater Quality in the Monterey Bay and Salinas Valley Basins 2005

Download or read book Status and Understanding of Groundwater Quality in the Monterey Bay and Salinas Valley Basins 2005 written by Justin T. Kulongoski and published by CreateSpace. This book was released on 2014-07-10 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Monterey-Salinas study unit is nearly 1,000 square miles and consists of the Santa Cruz Purisima Formation Highlands, Felton Area, Scotts Valley, Soquel Valley, West Santa Cruz Terrace, Salinas Valley, Pajaro Valley, and Carmel Valley groundwater basins (California Department of Water Resources, 2003; Kulongski and Belitz, 2011). These basins were grouped into four study areas based primarily on geography. Groundwater basins in the north were grouped into the Santa Cruz study area, and those to the south were grouped into the Monterey Bay, the Salinas Valley, and the Paso Robles study areas (Kulongoski and others, 2007).

Book Status and Understanding of Groundwater Quality in the Madera Chowchilla Study Unit 2008

Download or read book Status and Understanding of Groundwater Quality in the Madera Chowchilla Study Unit 2008 written by Jennifer L. Shelton and published by CreateSpace. This book was released on 2013 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater quality in the approximately 860-square-mile Madera and Chowchilla Subbasins (Madera-Chowchilla study unit) of the San Joaquin Valley Basin was investigated as part of the Priority Basin Project of the Groundwater Ambient Monitoring and Assessment (GAMA) Program. The study unit is located in California's Central Valley region in parts of Madera, Merced, and Fresno Counties. The GAMA Priority Basin Project is being conducted by the California State Water Resources Control Board in collaboration with the U.S. Geological Survey (USGS) and the Lawrence Livermore National Laboratory. The Project was designed to provide statistically robust assessments of untreated groundwater quality within the primary aquifer systems in California. The primary aquifer system within each study unit is defined by the depth of the perforated or open intervals of the wells listed in the California Department of Public Health (CDPH) database of wells used for municipal and community drinking-water supply. The quality of groundwater in shallower or deeper water-bearing zones may differ from that in the primary aquifer system; shallower groundwater may be more vulnerable to contamination from the surface.
