Phase II Environmental Investigations

phase-II-environmental-investigationsAmerican Geosciences, Inc. is highly skilled at completing Phase II environmental 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 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 environmental 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 environmental investigations that American Geosciences, Inc. 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 associated with a property a university was interested in purchasing.

  • 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.

President Corporate Safety and Environmental
I take many of AGI’s attributes for granted.  I’ve had the distinct pleasure of working with AGI for over 25 years and many of the AGI staff I dealt with back then remain a part of the team today.  That cohesive history and continuity is lacking in today’s M&A driven climate.  What’s more AGI have the extraordinarily unique ability to “speak the language of the listener.”  Whether discussing a complex geotechnical aspect with a regulatory official, another consulting firm, or an environmental insurance representative, or a business executive weighing expense and liability decisions, AGI has the uncanny ability to pivot and communicate the same issue in terms better understood by the receivers.  More importantly, when listeners provide feedback, AGI listens, and understands their vocational language.  For these reasons, this boutique powerhouse has partnered with us from a 400M company to a Fortune 300 global enterprise.  Through it all, we’ve not lost sight of the people that enabled such growth which is why AGI remains our consultant of choice.”
