GW/ SW RELATIONAL ASSESSMENT (SRA)
Base flow
Baseflow that supports aquatic life.
Uses surface water criteria and reference values to evaluate ground water that interacts with surface water.
The SRA is based on the percent of samples that exceed a threshold related to the environmental conditions necessary to support aquatic life.
The SRA is used to assess samples obtained from spring vents, boils, seeps, runs and other surface water bodies associated with springs.
Other integrated information such as topography, hydrology, stratigraphy, percent baseflow, and microlanduse are also considered.
GROUND WATER RESOURCE INDEX (GRI)
Potable water
Highest designated use of ground water.
Uses ground water standards for contaminant groups such as BIOLOGICAL, NUTRIENTS, ORGANICS, INORGANICS AND SALTWATER INTRUSION.
The GRI is based on the percent of wells that exceed a ground water standard and is calculated with and without aquifer stratification.
The GRI is used to assess spring samples obtained from conduits, monitor wells and drinking water wells located in the springshed. Important areas are identified that may need further investigation.
