*Major groundwater basin (aquifer) is defined as a distinct underground body of water overlain by contiguous land and having substantially the same
geological and hydrological characteristics and from which groundwater wells yield at least fifty (50) gallons per minute on the average basinwide
if from a bedrock aquifer and at least one hundred fifty (150) gallons per minute on the average basinwide if from an alluvium and terrace aquifer,
or as otherwise designated by the Board.
*Minor groundwater basin (aquifer) is defined as a distinct underground body of water overlain by contiguous
land and having substantially the same geological and hydrological characteristics and which is not a major
groundwater basin.
