2018 - Status And Understanding Of Groundwater Quality In The Monterey-Salinas Shallow Aquifer Study Unit, 2012-13 - California Gama Priority Basin Project

Miscellaneous Monterey and San Luis Obispo County Documents and Reports

The study was designed to provide a statistically robust assessment of untreated-groundwater quality in the shallow aquifer systems. The assessment was based on water-quality samples collected by the U.S. Geological Survey from 100 groundwater sites and 70 household tap sites, along with ancillary data such as land use and well-construction information. The shallow aquifer systems were defined by the depth interval of wells associated with domestic supply. The Monterey-Salinas Shallow Aquifer study unit consisted of four study areas—Santa Cruz (210 km2), Pajaro Valley (360 km2), Salinas Valley (2,000 km2), and Highlands (5,250 km2).

The first primary component of this study—the …

2002 - North Monterey County Comprehensive Water Resources Management Plan

Monterey County Water Resources Agency Water Reports

North Monterey County experiences severe water supply and quality problems including falling water levels, seawater intrusion, and nitrate contamination. The region is in a significant state of overdraft where current demands greatly exceed the annual level of recharge. Without increased supplies, dramatic changes need to occur to the North County land use pattern to reduce demand. The Comprehensive Water Resources Management Plan combines water conservation, water supply, water quality, and land use actions into comprehensive policy alternatives. It is clear, however, that capital facilities are necessary if the problem is to be solved.

The study area overlies a portion of …

2018 - Groundwater Management In California, Michael Hanemann

Related Research and Documents

In 2014, the California legislature for the first time took some steps to create a framework for regulating groundwater pumping in over-drafted basins by adopting the Sustainable Groundwater Management Act (SGMA), representing California's first statewide groundwater management planning program. SGMA called for local agencies to develop groundwater sustainability plans within the next five to seven years and then achieve sustainable levels of groundwater extraction by approximately 2040 to 2045. California's prior efforts to regulate groundwater extraction is discussed, as well as groundwater depletion.

2003 - Salinas Valley Sediment Sources

Related Research and Documents

The Salinas River is listed by the Environmental Protection Agency (EPA) under the Clean Water Act’s ‘303d list’ as being impaired due to ‘sedimentation/siltation.' A plan for management of the total maximum daily load of sediment is thus mandated. This plan was to include an assessment of sediment sources in the Salinas Watershed. The study provided the technical basis for this source analysis, to be used by the Central Coast Regional Water Quality Control Board (CCRWQB) in the development of the Salinas Sediment TMDL.
