American Geosciences is highly skilled at completing Phase II environmental site investigations to assess potential environmental impacts at a property. We access the magnitude and extent of environmental impacts to soil, groundwater, surface water, sediment, soil gas, and indoor air.
Since 1990, AGI has performed Phase II environmental site investigations at hundreds of properties including: steel mills, chemical plants, manufacturing facilities, dry cleaners, gas stations, shopping malls, etc., within the US, Mexico, and Canada.
Phase II investigations are specifically tailored to your site. And, the scope of work is designed to meet the scrutiny of parties involved including regulators, attorneys, lenders, etc.
Examples of site investigations that American Geosciences professionals have conducted include:
- Migration of solvents into a residential district from a former manufacturing plant, via vapors and groundwater.
- Sludge pit investigation near a city park.
- Former scrap yard issues up-gradient of city water supply wells.
- Gasoline vapors in the basements of numerous residential homes.
- Mercury impacts in soil of a former foundry/tannery as part of a bank foreclosure.
- Solvent impacts to soil and groundwater at a former heat exchanger manufacturer.
- PCB-contamination of concrete in the basement of a high-rise building.
- Tank issues associate with a property a university was interested in purchasing.
AGI’s Phase II environmental site investigation capabilities include:
- Review preliminary site information (prior reports, plant records, personal accounts, historical aerial maps, etc.).
- Research property ownership, document/map property boundaries.
- Evaluate potential off-site sources of concern.
- Develop site-specific investigation plans.
- Determine drilling and sampling locations (surface water, groundwater, soil, etc.).
- Hire subcontractors (surveyors, drillers, excavators, lab, etc.)
- Prepare site-specific health and safety plans.
- Secure bonds.
- Handle the submittal of public notices.
- Secure off-site access (if wells or sampling are needed on neighboring property).
Field Investigation Activities
- Coordinate with and supervise subcontractors.
- Advance soil borings to assess the quality of soil.
- Install monitoring wells to assess groundwater quality.
- Collect samples (one-time collection events or periodic collections over years).
- Pack samples, submit to lab, and instruct analytical tests to be conducted.
- Collect GPS information.
- Maintain site security and integrity of wells.
Post Field Investigation Activities
- Interpret field and sample information.
- Compare sample results to individual state standards.
- Prepare data tables summarizing site specific data to applicable standards.
- Evaluate and determine exposure pathways.
- Prepare risk assessments.
- Document site conditions and the extent of impacts.
- Prepare environmental covenants.
- Work with site restoration contractors.
AGI professionals present the magnitude of any issues, remediation options, and remediation budgets.
