WA410 - Ground-Water Flow in the Vicinity of Dry Docks at the Puget Sound Naval Shipyard, Washington - Completed FY1998
Background - To help evaluate the potential environmental threat of contaminants in ground water at the Puget Sound Naval Shipyard and to help plan remediation work at this facility, the U.S. Navy needs to know what fraction of ground-water discharge from the eastern part of the facility is directly to Puget Sound and what fraction is to dry docks.
Objectives - The objectives of the study are to determine if ground-water discharge from the eastern part of the shipyard is mostly to dry docks rather than directly to Puget Sound, to estimate average rates of fresh and salt water drainage to each of the dry docks, and to determine salinities and concentrations of selected contaminants of inflows to and outflows from the dry docks.
Approach - Ground-water discharge rates to the Sound and to the dry docks will be estimated using one or more numerical ground-water flow models. Salinities and concentrations of selected contaminants will be determined by taking and analyzing samples from wells and from inflow and outflow drains.
