USGS Groundwater Information: Branch of Geophysics
|
Research at the Massachusetts Military Reservation, Cape Cod, was conducted in the area known as the "gravel pit." The yellow cables are electrical resistivity cables. Metal pipes indicate location of sampling sites. Boreholes are encased in white PVC casing. |
Denis LeBlanc (USGS, WRD), Steve Gorelick (Stanford University), Kamini Singha (Stanford University), Christopher Uyeda (Stanford University), and Kathy Hess (USGS, WRD) conduct a site visit. |

Kamini Singha (Stanford University) installs a flexible borehole liner. |
Kamini Singha (Stanford University) collects water samples using a multi-level sampler (MLS) to monitor salinity and conductivity values during tracer injection. |
|
Marcel Belaval (OGW, Branch of Geophysics) lowers electrical resistivity cable into borehole. |
Chris Kochiss (OGW, Branch of Geophysics) monitors conductivity of water samples. |
|
Kamini Singha (Stanford University) and Mike Lambert (OGW, Branch of Geophysics), analyze preliminary data in the field. |
Kamini Singha (Stanford University) and Mike Lambert (OGW, Branch of Geophysics) conduct electromagnetic induction borehole logging. |
