Facilities for hydrogeologic studies are shared by Earth Sciences and the Center for Applied Earth Science and Engineering Research (CAESER). Surface-water equipment includes three stream gaging meters and a doppler remote discharge system. Groundwater equipment includes three varieties of submersible pumps, ranging in capacity from low-discharge sampling to high discharge purging. Water sampling apparatus, include bailers and a discrete interval sampler. Water-quality measurements are available using a YSI 6600, DO-pH-ORP-Cl-NO3-NH4 probe system with both flow-through and submersible options.
