Brackish Groundwater

Brackish groundwater is common in Southern California and is predominate within the San Diego Formation (see below).  Brackish groundwater makes up a portion of the total amount of water stored in aquifers.  Brackish groundwater is defined by the amount of total dissolved solids (TDS) the water contains.  Technically brackish groundwater contains 1,000 to 10,000 milligrams per liter (mg/L) of TDS.  In comparison fresh water contains under 1,000 mg/L of TDS and seawater contains over 35,000 mg/L of TDS.

Desalination technology is required to treat brackish groundwater through reverse osmosis.  We can provide groundwater water tests to measure TDS.  In addition provide treatment solutions.
