Examples of Impacted groundwater in a sentence

  • Impacted groundwater is located between six and 24 feet below the ground surface at both parcels.

  • Impacted groundwater in this area is collected by the north purge well system.

  • Impacted groundwater is present in this area at a shallow depth (approximately 13 ft bgs) and it is possible it would be encountered during activities such as a utility line excavation or repair of the FDR roadway infrastructure.

  • Impacted groundwater exists at the Paint Pit and Sign Shop Vat HWMUs; however, historical groundwater trends have shown that concentrations of COCs at these units have declined, therefore indicating groundwater plume stability.

  • Impacted groundwater from Site 11 flows south and, therefore, has not adversely impacted subparcel SR-W-2.

  • Impacted groundwater flows off-site, discharging to the Mississippi River.

  • Impacted groundwater in the 200-ZP-1 OU is widely dispersed and consists of overlapping groundwater plumes (i.e., all the highest concentrations or the lowest concentrations do not occur at the same location).
