The site was constructed as a service station on former agricultural land in early 1997. Four USTs were installed. In May 1997, a 500-gallon unleaded gasoline discrepancy was found in the fuel inventory system. Free product was identified in leak detection well MW-3 located along the southwest corner of the UST area. Approximately 60 gallons of gasoline was recovered from the secondary container lid, filtered and returned to the UST. LUST release number 4698.01 was assigned in May 1997.     

Approximately 160 gallons of gasoline were removed by pumping out free product from MW-3 in 1997. Site characterization activities started and continued through 2008 and included the installation of soil borings and eight monitoring wells. A Soil Vapor Extraction/Air Sparge (SVE/AS) system operated between June and October 1998. Under the Corrective Action Plan, Passive Biodegradation was the remedial choice after the SVE/AS system was removed in 2002. A ninth monitoring well was installed in 2016 to complete site characterization. A site specific risk assessment and detailed file/information search were also completed at the site.  Methyl Tertiary Butyl Ether (MTBE) concentrations in groundwater in MW-4 and MW-6 remain above regulatory standards.  

Based upon the results of  remedial activities and site-specific information, the above-referenced LUST site is eligible for alternative LUST closure under Arizona Revised Statutes (ARS) §49-1005(E).  Arizona Administrative Code (AAC) R18-12-263.04 allows case closure of a LUST site with groundwater contamination above the Arizona Aquifer Water Quality Standards (AWQS) or Tier 1 Standards.
