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. Much of the data is in USGS WATSTORE database; some exists only in paper and spreadsheet format at Maryland Geological Survey.

The collection consists of (a) approximately 50 field notebooks from geologic mapping, including field maps showing outcrop locations corresponding to the field notes and in some cases draft copies of quadrangle geologic maps, (b) approximately 20 notebooks and associated sample location maps from the Chesapeake Bay Earth Science Study (CBESS), and (c) 1 notebook from the Hart-Miller Island Monitoring Study. Some notes are in pencil and may be difficult to read.

The collection consists of Excel files describing each aquifer test, containing raw data, plots, and calculations of hydraulic properties (Coastal Plain only) and list of references associated with the collection. 262 well locations currently have digital aquifer test data (345 well locations have hydraulic properties described in published report). Aquifer (pump) tests, Maryland Coastal Plain. 1.The collection is essential for the evaluation of the sustainability of ground water in the Maryland Coastal Plain, and it is used as criteria to determine the quantity of ground water in a ground water appropriation permit license. 2.The long-term goal is to incorporate pump tests from non-Coastal Plain provinces/Piedmont...

To date, the collection consists of about 4,200 unprocessed, surficial sediment (grab) samples collected by Maryland Geological Survey (MGS) from the bottom of the Maryland Chesapeake Bay and its major subestuaries between 1976-1984, as part of the Chesapeake Bay Earth Science Study (CBESS), a multidisciplinary research effort authorized by Maryland and Virginia through the U.S. Environmental Protection Agency (EPA). MGS collected samples according to two sampling schemes, mid-bay and nearshore, and then processed them to develop a baseline inventory of certain physical and geochemical characteristics of bay bottom sediments, in particular, water content, grain size composition, and carbon and sulfur content. Since...

Unpublished reports, usually associated with a specific project involving Maryland Geological Survey (MGS) staff.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 via the Internet.

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
