Michigan Part 201 – Sites of environmental contamination.
Contaminants include:
Solvents Chlorinated Solvents, Oils, PCBs, Heavy Metals, Volatile Organic Compounds (VOCs), Semi-Volatile Organic Compounds (SVOCs), Petroleum Hydrocarbons, Herbicides and Pesticides, and
Michigan Part 213 - Leaking Underground Storage Tank Sites
Contaminants include:
Petroleum hydrocarbons, Gasoline, Kerosene, Diesel fuel, Solvents, Oils, and Heavy Metals.
Michigan Part 215 – Underground Storage Tank Sites
Site Assessment for prescreening an underground storage tank site or
Site Assessment for existing underground storage tanks for closure/removal.
Sampling and Field Methodology:
“Low Flow” or minimal drawdown groundwater sampling is used for sampling groundwater at the sites being evaluated.
Soil borings are completed using hollow stem augers and split spoon sampling for soil sampling, temporary well or other groundwater sampling techniques and monitoring well placement and construction.
Soil borings are also completed using direct push technology such as Geoprobe’s® machinery allowing soil and groundwater sampling. Direct push technology can also be used to place small diameter monitoring wells.
Geophysical surveys are completed for tank, pipeline and other metalic item location, and formation or stratum picking. Surface surveys include: resistivity, ground penetrating radar, electromagnetic and gravity. Subsurface surveys include: Natural gamma ray, or resistivity. Neutron, induced gamma ray and porosity surveys may be completed in large diameter boreholes/wells.
