Notes:

  1. The laboratory PQL ranged from 0.005 mg/kg to 10 mg/kg. The PQL of 0.005 mg/kg was the most consistently reported (7 of 12 total samples).

  2. Background values from Evaluation of Background Metals Concentrations in Soil Types at Camp Stanley Storage Activity. The site is located on soils of the Tarrant Association, gently undulating (TaB).

  3. Industrial risk reduction standards for groundwater protection and soil-air ingestion.

  4. Analysis performed by Chemron Incorporated.

Concentration exceeding RRS1 background levels are in bold type.

Concentrations exceeding RRS2 standards are highlighted.

Data Qualifier

U  The analyte was analyzed for, but not detected. The associated numerical valued is at or below the MDL.

F  The analyte was positively identified but the associated numerical value is below the RL.

M  A matrix effect was present.

E  The sample was diluted; dilution factor is presented in the raw data.
