This is a public health concern as groundwater is often the primary water source in the region. [1] Near-term solutions to reduce pollution and overuse are often costly and hard to implement in a timely manner. [5]
California has had a long history of complex water rights dealing with the ownership and management of surface water. Groundwater has stayed under the regulation radar, which led to the overdraft of vital basins and the subsidence of land taking place throughout the Central Valley. The SGMA gives responsibility to both state authority and local ...
California passed its landmark groundwater law in 2014. The goals of sustainable management remain a long way off. Despite California groundwater law, aquifers keep dropping in a 'race to the bottom'
The law was based on the idea that groundwater could best be managed at the local level, and it called for newly formed local agencies to gradually adopt measures to address chronic declines in ...
To meet the lofty goals of California’s 2014 Sustainable Groundwater Management Act, the authors estimated that users statewide will need to reduce groundwater pumping by about 19.2 percent by ...
Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
Estimates suggest up to 900,000 acres of farmland in the San Joaquin Valley alone might need to be fallowed to reduce the drawdown of groundwater and balance supply and demand.
In California, groundwater accounts for around 41% of the state's total water supply, [1] although this number varies between wet and dry years. During years of greater than average rainfall, less groundwater is used to allow for reserves to be available during dry years. Up to 60% of all water can be sourced from groundwater during dry years.
