Alternative Title

Site Assessment and Remediation of an Oil-Producing Property

Session Start Date

6-1-1988

Abstract

An assessment of a 6.78-acre parcel of oil-producing land with one active, seven idle, and two abandoned oil wells was performed. Following the collection and review of site data, an evaluation was made of the toxic properties of on-site soils for the presence of hazardous substances. Soil samples were collected by advancing boreholes at eight locations. These locations were selected on the bas is of the results of an aerial photographs review, a geophysical survey, and statistical sampling design techniques. An analytical program was conducted to test for chemicals that would likely be present from the oil field operations. It was concluded that the on-site soils are not hazardous. However, soils contaminated with petroleum hydrocarbons were identified. A soil gas survey was performed to evaluate the presence of methane and other hazardous gases. Based on the results of the survey, recommendations for reducing the adverse effects of such gases were developed, which were incorporated into the design of the building foundations. A soil remediation plan was developed and approved by the regulatory agencies. The contaminated soils were excavated, blended with clean soils, and recompacted under areas to be paved. The existing oil wells were abandoned, and the previously abandoned wells were re-abandoned in accordance with the applicable standards.
