| Notes: Methods are from Test Methods for Evaluating Solid Waste Physical/Chemical Methods, EPA publications SW-846. NA = not analyzed or not applicable ND = not determined GWP = Groundwater protection standard for industrial use. Concentration in industrial soil assumed protective of groundwater considering cross-media contamination of groundwater from contaminated soil. SAI = Soil/Air Ingestion standard for industrial use. Maximum concentration in industrial soil. mg/kg = milligram per kilogram ug/kg = microgram per kilogram 1 - All other SW8260 VOC analysis constituents are at non-detect levels. 2 - Composite sample 3 - Remediate/removal of waste materials to background levels, per 30 TAC 335 subchapter S. Background values are preliminary. | ||||||||||||||||||
