Specifications include, but are not limited to: • Site surveys (may include physical features, geological features, geophysical surveys, soil gas surveys); • Site plan and location map preparation (including GPS location of the spill location [latitude/longitude, 5-meter accuracy]), surface and subsurface features, groundwater level contours, compound-specific contaminant isoconcentration contours, spill location specific geologic maps); • Identification of actual and potentially hazardous waste sources; • Installation of monitoring wells, piezometers, test pits or other exploratory techniques for evaluation of the spill site (including direct-push technology); • Collection and analysis of soil, soil vapor, sediment, water and air samples to determine type, degree, and extent of contamination. The contractor shall indicate their ability to perform low flow sampling; • Determination of spill location specific geologic and hydrogeologic characteristics (including collection of core samples, soil characterization tests, vapor pump tests, aquifer pump tests, slug tests, geophysical surveys, fracture trace analysis); • Determination of receptors impacted or threatened by contamination (including collection of air, soil and water samples from receptor locations); • Determination of exposure to released contaminants (including indoor air vapor surveys, packer tests);
