Iredell County, NC
The Langtree Peninsula Groundwater Monitoring and Research Station (LPGMRS) is located off Langtree Rd, on the Lake Campus of Davidson College, in Iredell County, North Carolina (Figure 1). The LPGMRS is located within the Charlotte lithotectonic terrane and metaigneous intermediate-composition hydrogeologic unit. Quartz diorite is the predominant rock type at the site. The site was selected to evaluate the effects of intrusive rock types with intermediate rock composition on groundwater quality, thickness and composition of the regolith, thickness and characteristics of the transition zone, characteristics of bedrock fractures, and to study the interaction of groundwater with Lake Norman, which borders the site to the north.
The LPGMRS consists of six monitoring well clusters and eleven piezometers. Each well cluster consists of two or three wells, Well cluster 2 has real-time water level and water quality monitoring devices, which are maintained by the U.S. Geological Survey. Seven continuous soil and bedrock cores were collected from the site. The wells and piezometers are positioned following a generalized flow path from recharge to discharge area. The elevation at the LPS ranges from approximately 762 to 813 feet in altitude. Surface runoff from the site drains to the north into Lake Norman – North Carolina’s largest freshwater reservoir – located on the Catawba River.
