Collection consists of paper and electronic files of data from individual wells and springs that have been tested for water quality as part of an ongoing statewide assessment of ground-water quality. Data from the collection is documented in publications and annual administrative reports. Results of groundwater samples collected by the Maryland Geological Survey that were analyzed by the USGS National Water Quality lab have been entered into the USGS National Water Information System (NWIS). Some laboratory results of groundwater sample analyses from state or private labs exist only in paper and spreadsheet format at the Maryland Geological Survey and have not been fully inventoried or catalogeed.

Unpublished reports, usually associated with a specific project involving Maryland Geological Survey (MGS) staff. Generally, these are file reports or open-file reports that meet the terms of a grant or contract but are not otherwise distributed or included in the MGS List of Publications. They are commonly, but not necessarily, associated with a particular collection(s). Reports, both paper and digital, need to be collected in a central location, organized, catalogued, and archived. Eventually, they should all be digitized/scanned and be made available electronically.
