Real-Time River Monitoring - City of IndianapolisProject Overview
The White River, subject to accidental spills, combined sewer overflows, and pollution from industrial sites, requires constant monitoring to protect public health. There have been several reported fish kills on the River in recent years, and something needed to be done to maximize the effectiveness of its monitoring efforts.
The City needed to create a system where they could quickly retrieve water quality data from various points around the city and analyze it for possible signs of contamination. Therefore, the City of Indianapolis implemented a NexSens real-time data collection network that provides City officials with up-to-the-hour water quality data from multiple sites along the river.
System Description
YSI 6600 multi-parameter sondes are used to monitor temperature, conductivity, dissolved oxygen, pH, ORP, and turbidity. Data from all sites is transmitted to a centralized computer via cellular modems on NexSens 3100-iSIC data loggers.
iChart software stores the data in a secure database and automatically posts real-time data to a local network drive where it is easily viewed by city personnel. The software automatically generates custom reports at set intervals, which simplifies data management and review. For immediate spill detection, alarms are set-up to send emails or page someone when parameters are out of their acceptable ranges.
With NexSens continuous, real-time data, the City is able to quickly respond to water quality impairments and identify contamination sources, as well as improve data quality, while saving time and money. | NexSens 1001 | iChart software | NexSens WQData-6 | Annual data hosting package for up to 6 field sites, additional site expansion available | NexSens 3100-iSIC | iSIC data logger with cellular modem telemetry | NexSens AVSS241608 | Stainless steel enclosure, 24" x 16" x 8" | NexSens A56 | Unistrut mounting kit | NexSens A38-P | Ground kit, pipe attachment | NexSens A22 | Solar power kit, 20-watt | NexSens A49 | High gain antenna, cellular frequency, tri-mode, 2 dBd | NexSens A36 | RF cable, micro-loss, 6' | YSI 6600-00 | YSI 6600 V2-2 Sonde with temperature/conductivity sensor | YSI 6565 | pH/ORP sensor | YSI 6562 | Dissolved oxygen sensor, polarographic, rapid-pulse | YSI 6136 | Turbidity sensor with self-cleaning wiper | YSI 6091 | Field cable, 25 ft. | NexSens MB-300 | Monitoring buoy, 30" dia. polymer-coated foam hull, 300 lb. buoyancy | Carmanah 501-A15 | LED Beacon with solar power, 15 flashes per minute (064), amber | NexSens 3100-iSIC | iSIC data logger with cellular modem telemetry | NexSens A20 | Solar power kit, 5-watt.
