The Snyder field study area (the site) consists of salt-impacted soils and springs located southeast of the town of Coahoma, Howard County, Texas (Figure 1). The impacted area is located within the Snyder Oil Field on Susie B. Snyder and O.D. and M. H. O'Daniel leases. At least four separate groundwater seeps are discharging saltwater to the ground surface, resulting in two separate barren areas. The discharge area has been ditched to contain the flow, which is routed to a former stock tank. This tank drains to an unnamed tributary, which joins Beals Creek approximately 2 miles downstream. Although surface flow in the tributary is ephemeral, there is concern that the site may be impacting Beals Creek and, subsequently, surface-water ponds downstream.

The oil field has been developed in the study area primarily since 1953. A "no-pit" order for Snyder field was issued in July 1959 (memorandum dated March 10, 1992; Appendix I, from Charles Ross to Felix Dailey) by the Railroad Commission of Texas (RRC). Currently, produced water is reinjected at a series of injection wells throughout the oil field to maintain oil production. The RRC has used state funds to investigate the source of the saltwater at the site. A number of producing oil wells and injection wells were tested for casing integrity by the RRC in 1997. A number of wells in the area were plugged by operators before and during 1995.
