The Colorado Water Watch monitoring stations are equipped with real-time water quality sensors and are situated in close proximity to oil and gas operations. They are designed to continuously look for any changes in baseline groundwater quality using surrogate indicators. The real time data is automatically collected and wirelessly transferred to the Colorado Water Watch database once every hour. The monitoring data is then analyzed using advanced anomaly detection algorithms that can examine historical patterns and detect any changes in the water quality. The analyzed data is published on the Colorado Water Watch website for public access. In cases where an anomaly in the water quality data appears, Colorado Water Watch further analyzes it and then, in “near-real time” reports it on the website, with an explanation about the anomaly.
