Infiltration will occur where local groundwater elevation is higher than the sewer pipe. Gravel bedding materials in sewer pipe trenches act as a French drain. Groundwater flows parallel to the sewer until it reaches the area of damaged pipe. In areas of low groundwater, sewage may exfiltrate into groundwater from a leaking sewer. [6]
The Groundwater Ambient Monitoring and Assessment Program (GAMA) is an all-inclusive monitoring program for groundwater that was implemented in 2000 in California, United States. It was created by the California State Water Resources Control Board as an improvement from groundwater programs that were already in place.
After state regulators determined in 2022 that the Kern groundwater plans were inadequate, the 14 so-called groundwater sustainability agencies in the area began splitting and forming new local ...
Prior to SGMA, groundwater use was under-regulated to a point where many areas of the state faced major depletion, particularly in the San Joaquin Valley and other groundwater basins on the central coast and southern California that have been designated by the State's Department of Water Resources (DWR) as being critically overdrafted.
California officials voted Tuesday to step in to monitor groundwater use in part of the crop-rich San Joaquin Valley in a first-of-its-kind move that comes a decade after local communities were ...
The law has led to the collection of more groundwater data and nearly $1 billion in state funding, and has raised public awareness about how heavy pumping, particularly for agriculture, has ...
A diagram of a traditional French drain. A French drain [1] (also known by other names including trench drain, blind drain, [1] rubble drain, [1] and rock drain [1]) is a trench filled with gravel or rock, or both, with or without a perforated pipe that redirects surface water and groundwater away from an area.
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'
