THEORETICAL BACKGROUND AND PROJECT RATIONALE There can be eight different well types at a location. They include, monitoring, irrigation, injection, boring, dewatering, recovery, extraction, and potable water. At NJARNG facilities, most of the wells encountered were monitoring wells used to monitor the groundwater for certain contaminants. The wells were checked for any defects and they were inspected using a multi-gas monitor. For each well, GPS coordinates were acquired and permit numbers were used to label each assessed well. Well integrity and condition were also assessed, and then samples were taken for volatile organic compounds (VOCs), lower explosive limit (LEL), hydrogen sulfide (H2S), carbon monoxide (CO), and oxygen (O2) concentrations analyses.
Interns successfully completed field surveys for a statewide well inventory project started in FY2019. Intern Nick Gamarro finalized a 381 page report summarizing our survey results, in which records for nearly 300 monitoring wells, potable water wells, and extraction wells at 29 different NJARNG facilities were investigated. Survey results were compiled into a formal report, including methods, well locations, well photos, well location maps, well conditions, and a list of wells recommended for decommissioning. All well locations were entered into the appropriate feature class in the environmental geodatabase.
