Olentangy River Water Quality
Recently, the Ohio State University's Wilma H. Schiermeier Olentangy River Wetland Research Park (ORWRP) contacted NexSens Technology to install a water quality monitoring station with radio telemetry in the Olentangy River. As the confluence of the Allegheny and Monongahela rivers creates the Ohio River, it was imperative that a system be developed with the capability to detect and track any possible contamination in either of the two rivers. Population sizes have been declining in many species of bats and NexSens micro-T temperature sensors are being used to generate a thermal map of a habitat area. Two water quality monitoring stations were deployed: one where Old Woman Creek enters the preserve and another near the mouth of the estuary. At various locations throughout the wetlands, NexSens radio telemetry, YSI 600 LS multi-parameter sondes with temperature, conductivity, and water level sensors, and RM Young tipping bucket rain gauges were installed. Every 60 minutes, NexSens Technology radio telemetry transmits soil, weather, and solar radiation data from numerous, remote sites to a base station computer at a centralized laboratory. The YSI 6-series multi-parameter sondes with temperature, conductivity, pH, dissolved oxygen and turbidity were selected for water quality monitoring. YSI 6600 multi-parameter sondes are used to monitor temperature, conductivity, dissolved oxygen, pH, ORP, and turbidity. The YSI 6-series multi-parameter sondes were chosen for water quality monitoring. The system consists of a buoy containing multiple sensors that monitor real-time conditions in the Ohio River. Conductivity, dissolved oxygen, pH and turbidity sensors were selected for water quality monitoring. NexSens configured a data logging and radio telemetry system to continuously monitor Hudson River water quality and water level as well as local weather conditions. The ARBOR restoration site includes one bridge mounted and four well installed, YSI multi-parameter sondes along a one-mile stretch of the White River and the Western edge of the IUPUI Campus. Fondriest Environmental was contacted to configure and help setup a notification system that met the requirements of the consulting firm's specs. The effluent alert notification system is comprised of a NexSens 3100-iSIC cellular data logger at the effluent site. The release of overly warm surface water, or oxygen-depleted bottom water, at selective withdrawal dams could devastate downstream fish populations. Near the upstream reservoir of the power plant, two YSI 6600EDS sondes are deployed at different depths to monitor water quality before flowing through the hydroelectric plant into a river. Columbus Public Utilities officials asked Fondriest Environmental to supply and install real-time data telemetry systems to monitor water quality in along drinking water reservoirs.
