In the midst of a struggling economy, severe drought, and limited financial resources, Rusk County Groundwater Conservation District (RCGCD), in Henderson, Texas has managed to overcome these obstacles with great success. Gathering scientific data to preserve and protect the groundwater is the mission statement for RCGCD. In an effort to carry out this mission, RCGCD implemented rule 9.2.5 which requires exploration companies to either plug or have their water well inspected within 180 days of the oil/gas rig leaving the site. During inspection the use of a portable water well camera system, a sub-foot accuracy Trimble Pro XRT GPS unit, and geophysical electric logging equipment help determine the integrity of the well and the groundwater. To overcome the financial burden, the district requires an inspection fee to cover the cost of the district’s time and equipment. Over 400 electric logs (elogs) from inspections and historical wells have been submitted to professional geologists to help decipher the geologic stratigraphy as well as the major sands comprising the majority of the groundwater. Along with the elogs, each quarter RCGCD collects static water level measurements from 100 wells that are no longer in use from exploration companies. Combining this scientific data (elogs and water level measurements) into a Geographic Information System (GIS), a 3D groundwater model has been created for the entire county, which provides valuable information on the geophysics and groundwater. This one rule not only benefits the district’s groundwater monitoring efforts, finances, networking, and the integrity of the groundwater resources, but also the exploration companies’ practices by providing a form of litigation insurance which they gladly support.
