Ambient Groundwater Monitoring
The Oklahoma groundwater monitoring program is funded by a portion of the money authorized for water quality monitoring under the Clean Water Act.
Groundwater Aquifer Maps
This project resulted in mapping of water quality data for the major aquifers in Oklahoma. Maps were generated for Total Dissolved Solids, Sulfates and Nitrates. The data came from an ambient monitoring effort begun by the Oklahoma Department of Environmental Quality two years ago and from historical public water supply well data. There are sets of maps for bedrock and alluvial aquifers. Some aquifers lacked adequate data to support the creation of maps.
