Aboveground and Underground Storage Tank Investigation and Remediation

GGI has performed all segments of the investigation and remedial activities specified under the regulations overseen by the both the Petroleum Storage Tank Bureau (PSTB) and the Ground Water Quality Bureau (GWQB) of the New Mexico Environment Department, for sites with tanks used for the storage of petroleum products and other hazardous products.

Examples of Previous Projects:

» Santa Fe County Maintenance Yard at Galisteo Road: GGI conducted a multi-stage Minimum Site Assessment (MSA) that consisted of drilling of soil borings in the area of two underground storage tank systems. GGI was able establish a vertical separation of over 170 feet between any shallow contamination remaining in the soil and the first occurrence of shallow ground water. GGI also conducted remediation of a diesel release at the yard from an aboveground storage tank. This effort included the excavation of the hydrocarbon-contaminated soils, sampling of soils for waste disposal and closure, and confirmation soil borings following the excavation of soils. The GWQB issued a determination of No Further Action to the County following the remedial effort completed by GGI.

» Former New Mexigas Station: This site is located in Santa Fe, NM. GGI was retained by Berridge Distributing, Inc. to determine the horizontal and vertical extent of hydrocarbon contamination in alluvial and bedrock aquifers. GGI supervised the completion of more than 15 soil borings and groundwater monitoring wells. GGI also designed and installed a combination soil venting/sparging system to remediate dissolved phase hydrocarbons in soil and groundwater beneath the site, and performed quarterly monitoring.

» Indian Hills Site Investigation:This site is east of Albuquerque near Zuzax along US Interstate 40 in an area of very complex geology and hydrology. GGI developed a program to conduct geologic mapping, sample domestic wells and drill monitoring wells to determine cause and extent of groundwater contamination in three separate aquifers and two localized perched zones within 240 feet of ground surface. GGI was responsible for geologic mapping and fracture analysis, compilation of geohydrologic cross sections, installation and sampling of 24 monitoring wells, lithologic description of continuously cored samples and completion of well nests, identification of likely contaminant sources and pathways, and pilot scale remediation testing.

» Houston Lumber: This site is located on Cerrillos Road in Santa Fe. GGI conducted a soil contamination investigation in 1989. The site was closed by the PSTB, but was reopened in 1999. GGI conducted a MSA that consisted of drilling three monitoring wells, soil and ground water sampling for hydrocarbons, and extensive monitoring of soil vapor during construction of a new building at this site. GGI also continued to conduct quarterly monitoring of groundwater in the three on-site monitoring wells and 8 wells located across the street from the site.

» Jiffy Lube: This site is located at Cerrillos and St. Michael’s Drive in Santa Fe. GGI performed a MSA at this site that included several soil borings and completion of a 135 ft deep monitoring well using a hollow-stem auger drill rig. Compliance monitoring was conducted by GGI and the site closed by the PSTB.

GGI has the ability to offer the client assistance from the initial discovery of a release to the final issuance of the No Further Action letter by NMED.
