In March 2016, the U.S. Geological Survey drilled a borehole, MA-FSW-750-0100, through the unconsolidated sediments and 1.5 m into the bedrock in East Falmouth, Massachusetts, to improve understanding of the glacial history and hydrologic properties of the Cape Cod aquifer. Prior to drilling, candidate sites were investigated using surface geophysical methods. Passive seismic horizontal-to-vertical spectral ratio (HVSR) methods were used to estimate the depth of the unconsolidated deposits over bedrock. Transient electromagnetic (TEM) surveys were conducted to characterize the lithology and salinity of formation water in the subsurface, which was used to plan the borehole completion. The specific conductance of...
