Ground-Water and Surface-Water Quality Data for the West Branch Canal Creek Area, Aberdeen Proving Ground, Maryland, November 1999–May 2001

By Tracey A. Spencer, Daniel J. Phelan, Lisa D. Olsen, and Michelle M. Lorah

 

Abstract

This report presents ground-water and surfacewater quality data from samples collected by the U.S. Geological Survey from November 1999 through May 2001 at West Branch Canal Creek, Aberdeen Proving Ground, Maryland. The report also provides a description of the sampling and analytical methods that were used to collect and analyze the samples, and includes an evaluation of the quality-assurance data.

 

The ground-water sampling network included two 4-inch wells, two 2-inch wells, sixteen 1-inch piezometers, one hundred thirteen 0.75-inch piezometers, two 0.25-inch flexible-tubing piezometers, twenty-seven 0.25-inch piezometers, and forty-two multi-level monitoring system depths at six sites. Ground-water profiler samples were collected from nine sites at 34 depths. In addition, passive-diffusion-bag samplers were deployed at four sites, and porous-membrane sampling devices were installed in the upper sediment at five sites. Surface-water samples were collected from 20 sites.

 

Samples were collected from wells and 0.75-inch piezometers for measurement of field parameters and reduction-oxidation constituents, and analysis of inorganic and organic constituents, during three sampling events in March–April and June–August 2000, and May 2001. Surface-water samples were collected from November 1999 through September 2000 during five sampling events for analysis of organic constituents. Ground-water profiler samples were collected in April–May 2000, and analyzed for field measurements, reduction-oxidation constituents, and inorganic constituents and organic constituents. Passive-diffusion-bag samplers were installed in September 2000, and samples were analyzed for organic constituents. Multi-level monitoring system samples were collected and analyzed for field measurements and reduction-oxidation constituents, inorganic constituents, and organic constituents in March–April and June–August 2000. Field measurements and organic constituents were collected from 0.25-inch piezometers during three sampling rounds in March–April and June–August 2000, and May 2001. Porous-membrane sampling devices were installed at depths of up to 3 feet and sampled for organic compounds and reduction-oxidation constituents in March and June 2000, and May 2001. Field measurements, reduction-oxidation constituents, inorganic and organic ground-water samples were collected and analyzed from 1-inch piezometers in May 2001."
