Groundwater levels in Dead Run watershed, Maryland, USA

This resource contains groundwater level data from 39 wells in Dead Run watershed near Woodlawn, MD, USA. Boreholes (51-mm diameter) were drilled using a Shaw backpack portable drill, with 25.4-mm ID PVC pipes inserted to serve as wells, each screened 0.3048 m at its lower end. Wells are installed in pairs with bottom elevations differing by about 1 to 3 m. Well pairs are installed either in the riparian zone or at the hilltop, relative to the Dead Run channel. Between 4 and 8 wells comprise a transact perpendicular to the stream. Wells are outfitted with vanEssen Micro-Diver pressure transducers. Barometric pressure is measured at one location using a vanEssen Baro-Diver. Groundwater level below land surface is calculated from site-specific information on location of the pressure transducer sensor point below land surface. Pressure transducer data are recorded at 5-minute intervals. Instruments were deployed in 2015 and maintained until failure or end of a project. Manual downloads of water pressure data are done every 5 months; downloads of barometric pressure data are done every 2.5 months. The wells are located in the Piedmont physiographic province, in suburban Baltimore, Maryland, USA in either saprolite or highly weathered fractured bedrock.
