Gaston County, NC
The Pasour Mountain groundwater monitoring and research station (PMGMRS) is underlain by layered metasedimentary and metavolcanic rocks of Blacksburg Formation in the Kings Mountain geologic belt. The PMGMRS is located on the Resource Recovery Farm of the City of Gastonia, near Bessemer City in Gaston County, North Carolina (Figure 1). The 700-acre farm lies in the Long Creek watershed of the S. Fork Catawba River and is actively managed for land application of wastewater and biosolids (Figure 2). The elevation at the site is about 900 ft. The site was chosen to study groundwater quality in the Kings Mountain area –an area located near a major tectonic boundary separating the Piedmont and Carolina zones, and noted for several shear zones and mineral deposits.
At the PMGMRS, there are 5 monitoring wells clusters, each consisting of a (upper) regolith well and a transition zone (lower regolith) well. Additionally, there are 4 (upper) regolith wells at different topographic locations at the site. The main objectives of this study are to: (1) characterize the groundwater quality in massive or foliated crystalline rocks mantled by a thick regolith and (2) evaluate the impact of wastewater and biosolid applications on the groundwater quality.
