Testing Field Techniques for Groundwater/Surface-Water Exchange


In July 2013 USGS hydrologists from the Office of Groundwater, the National Research Program, the Water Science Field Team, and the Massachusetts-Rhode Island Office of the USGS New England Water Science Center tested field techniques for groundwater/surface-water exchange along the Quashnet River on Cape Cod, Massachusetts.

The team installed and collected data from a variety of apparatus, including seepage meters, piezometers, streambed permeameters, minipoint streambed samplers, vertical temperature probes and fiber-optic (longitudinally) distributed temperature sensors, specific-conductance probes, and fluorometers (figs. 1-12). Dye and salt tracer tests were conducted to determine groundwater/surface-water exchange rates and to compare to streamflow measurements made at several gaging sites along the river.

*Field Safety Note: In accordance with the project's Health and Safety Plan (HASP), field personnel were not required to wear personal flotation devices (PFDs) during in-water work. The activities and locations shown in the photos above met the HASP requirements for an exemption from required PFD use.
