Ground Water - Water Quality Results

Groundwater quality data and related groundwater well information available on the page was queried from the GAMA Groundwater information system (**GAMA GIS**). Data provided represent a collection of groundwater quality results from various federal, state, and local groundwater sources. Results have been filtered to only represent untreated sampling results for the purpose of characterizing ambient conditions.

Data have been standardized across multiple data sets including chemical names and units. Standardization has not been performed for chemical result modifier and others (although we are working currently to standardize most fields). Chemicals that have been standardized are included in the data sets.
