NassCass field and project personnel are trained in the proper procedures for sample collection using numerous techniques including the following:
Soil sampling using hollow stem auger (split spoon), hand auguring/soil core, composite sampling, surface wipe sampling, etc.
Groundwater sampling from piezometers, remediation systems, groundwater monitoring wells and recovery wells,
open-hole samples, direct-push, etc.
Surface water sampling from streams, lakes, sewer lines, etc.
Our capabilities also include sampling of a wide variety of other matrices/substances, for example, those that may be identified in a Phase I ESA, such as tiles, roofing materials, unknown solid and liquid waste products, etc.
After collection, all samples are packaged following protocols defined by SW-846 Methods and delivered to certified labs under strict chain-of-custody, to be analyzed for contaminants of concern. NassCass personnel have collected and submitted numerous samples for a wide range of analyses, including the following types of contaminants:
