Abstract

This document provides a comparison of ASTM E-1599-94 Standard for a petroleum release and the procedures performed on a site assessment project in North Las Vegas. The major elements of a site assessment are thoroughly discussed in this document. They elements consist of the Initial Site Assessment, On-Site Delineation, Off-Site Delineation, Sampling/Analysis, and Site Assessment Methodologies.

The data was obtained through extensive research, utilizing reference documents,on-site experience, and the knowledge of Keith Stewart of Stewart Environmental.

After reviewing and comparing the data of my research, the procedures applied to the North Las Vegas Site (NLVS) were quite similar to the ASTM El599-94 standard, with only a few minor differences.

Conclusions and recommendations are discussed in this document. For example, the groundwater sample results from the NLVS returned non-detect. Therefore, no remedial action was required by the lead agency, Nevada Division of Environmental Protection (NDEP). I recommend that the elevations of the monitoring wells continue to be monitored monthly and samples should be extracted and sent to the laboratory to be analyzed quarterly for an additional year. Given the high concentrations of total petroleum hydrocarbons in the soil before excavation, I would also recommend a risk assessment be performed., to evaluate the future risk of potential contamination of the groundwater.
