GTA performed inspection and testing of 128 relief wells located on the land side of the flood control levee system along the Susquehanna River. The relief wells are positioned at the toe of the levee and are designed to relieve hydrostatic pressure in the levees during flood conditions. The majority of the wells are located in open grass areas, with some located on gravel roads and parking areas near maintenance buildings and other facilities. GTA provided visual wellhead inspections and conducted hydraulic testing at 128 well locations across the project area. GTA compiled and analyzed all data, and reported wellhead condition observations, pump testing data, turbidity measurements, and estimated 24-hour specific capacity for each well meeting the criteria for specific capacity calculation.
