AER completed Phase I, II, and III Environmental Assessments on the former Hale Mill located in Norwich, CT.

AER removed 3,800 gallons of non-hazardous waste, 6,000 pounds of non-hazardous sludges and decommissioned former industrial operation equipment pits.

The site will soon become a new resort/hotel/conference facility.




AER specializes in the environmental investigation and remediation of obsolete properties preparation for redevelopment. Working closely with the Connecticut Department of Environmental Protection and the New York Department of Environmental Conservation, AER assists in the "recycling" of valuable land resources. Our decisive action enables us to complete the task at hand in the most expedient manner possible.

With over 22 years of experience in all types of environmental investigation and remediation, AER's staff is well prepared to handle every environmental condition.

It is AER’s objective to design each remedial program to achieve the highest standard of effectiveness as well as being the most cost-efficient.

Due to years of experience in site evaluation and remediation, AER’s staff of qualified professional geologists, professional engineers, Licensed Environmental Professionals and Licensed Site Professionals have developed a keen understanding of industrial processes and property function. This type of detailed understanding allows AER to complete tasks more quickly and with greater precision.

AER has performed numerous site clean-ups that have taken environmentally-impaired properties and turned them into valuable assets. The remedial actions chosen are generally selected based upon the final site use, the current regulatory status and a cost comparison of available remedial alternatives.

Regulatory criteria are risk-based and developed regulatory to provide acceptable soil, groundwater and soil gas quality. These levels are generally accepted in most remedial scenarios, and in most cases, can be achieved cost-effectively.

Regulations can be modified, if appropriate, based upon specific site needs or contaminant characteristics. Alternative clean-criteria can be petitioned. The alternative criteria must also be risk-based and protective of human health and the environment.

AER's experience and project success has shown that Alternative Criteria are generally reserved for "special cases." Most properties can be effectively remediated using typical clean-up techniques (soil excavation and off-site disposal, soil venting, air sparging.) If Alternative Criteria provide the only means for site clean-up, AER evaluates an achievable alternative criteria using the most recent US EPA Risk Assessment Guidance for Superfund and local guidance.

AER personnel have been performing environmental studies in Connecticut and New York for the past 22 years; we have developed a very strong relationship with CTDEP and NYSDEC personnel. These strong relationships allow discussion rather than argument, and help a difficult project get completed more expediently. The discussions are supported by AER's thorough understanding of environmental laws and regulations.

AER personnel have extensive experience working with many prestigious law firms in the interpretation and application of environmental laws and regulations on the Federal, State and local level. Our thorough understanding of the regulations guides the environmental study or remediation and directly impacts project costs.
