These specifications provide details for conducting a soil boring and geophysical logging for the installation of three (3) 4-inch diameter monitoring wells for the purpose of confirming stratigraphy and water quality sampling and analysis to further evaluate the potential hydraulic connection to contaminated sites in the area surrounding East Windsor Municipal Utilities Authority (EWMUA) proposed water treatment site. The well sites are approximately 2,500 feet north of the intersection of Old Trenton Rd and Millstone Rd. in East Windsor, NJ as shown on the attached Figure 1. The overall scope includes conducting a test boring followed by geophysical borehole logging; then after data interpretation, drilling and installation of three (3) 4-inch diameter PVC monitoring wells along with development, short-term yield/water level testing and collection of water quality samples. The three monitoring wells will be installed as a "cluster", one well in the Upper PRM, one well in the Middle PRM (Farrington Sand) and one well in the Middle PRM (Potomac). The well cluster will be located near the southeast corner of the EWMUA property, as shown on Figure 1.
