HCEI Phase I Completion Report

The HCEI contractor, Geo Strata, has prepared a report documenting the implementation of Phase I.

HCEI Phase I Completion Report

The final data package for Phase I has been received from the laboratory and is posted below, along with a data-usability summary, dated July 15, 2010, containing an analysis of the quality assurance–quality control information in the HCEI final data package.

Updated Final Data Package

Combined Benzene, Toluene, Ethylbenzene, Xylene (BTEX), Total Petroleum Hydrocarbons (TPH), and Naphthalene Passive Soil-Gas Sampling Locations

Preliminary data maps for Phase I displaying values greater than the laboratory’s reporting limit have been prepared. No widespread masses of chemicals of concern were observed via this screening methodology. This data will be used in Phase II after the required quality assurance and quality control have been completed.

Note: The TPH data quantifiable by the laboratory (higher than the reporting limit of 2500 nanograms) appear in the Preliminary PSG Map, Part 2. The TPH levels are for a mixture of aliphatic hydrocarbons and do not include aromatic hydrocarbons such as benzene, toluene, ethylbenzene, and xylene.
