Groundwater Quality Monitoring Project

Groundwater discharge to an irrigation pond

Groundwater discharge to an irrigation pond.

Gaining understanding of the potential groundwater quality trends could significantly influence future environmental policies and management strategies related to its use. Previous studies indicate increasing trends of dissolved solids concentrations in groundwater from areas of the NCLAS and the South Coast aquifer. Aquifer overdraft can cause the thinning of the freshwater lens and consequently saline-water encroachment and degradation of groundwater quality.
