Environmental Engineering Services | Environmental Site Assessment

Environmental Engineering Services

Environmental Engineering Services is a critical part of any prospective property owner or buyer prior to the purchase of vacant land, commercial property to a heavy industrial property. It is to allow you, the real estate purchaser, to make an educated business decision by providing you with the information of the past and present activities that took place on and around that piece of property. The Environmental Site Assessment is to determine the possibility of contamination on the property and its impact.

Many times a Phase I and/or Phase II Environmental Site Assessment are conducted as part of property transfers. The Illinois Responsible Property Transfer Manufacturing PlantAct of 1988 – IRPTA, requires written disclosure of   pre-existing environmental conditions for commercial and real estate transactions in the State of Illinois.
United Analytical Services have been performing environmental consulting services since 1988 on properties ranging from vacant land, multi-housing, commercial properties and industrial properties. We have conducted hundreds of site assessments including historical study, sample readings and a final report. All projects are conducted in a timely manner in accordance with the American Society of Testing Materials – ASTM site assessment standards – E-1527-2005.

Our in-house talent of qualified professionals consists of experienced engineers and environmental scientists all with years of experience working on Phase I, Phase II environmental site assessments, environmental compliance audits by applying their extensive knowledge of Federal, State and local regulations.


Phase I of the Environmental Site Assessment
The environmental site assessment, Phase I is for the use of real estate purchasers needing to understand the history of a particular commercial, industrial or multi-Tank Removal Projectfamily property. We begin the process with an overall visual inspection in order to identify potential environmental issues such as soil stains, illegal disposal practices, underground storage tanks, above ground storage tanks, wetlands, building materials that contain asbestos, lead based paint, drinking water, radon and PCBs in electrical equipment. We will also inspect the surrounding properties to identify potential off-site sources of environmental contaminants.

The next step is to query property owners, managers and key facility personnel as well as review historical documentation including aerial photographs, deeds, records of use of the site and surrounding areas, regulatory compliance documentation for the site and surrounding areas, historic city directories, business directories, local geology, hydrology and water usage.
The final report documents our findings and summarizes the environmental conditions. We’ll also discuss any further testing necessary to address potential concerns.


Phase II Environmental Site Assessment
A Phase II subsurface investigation involves specific testing based on the results of the Phase I Environmental Site Assessment. Its purpose is to confirm or deny the presence of hazardous materials on the property or from the surrounding areas. Phase II may involve the collection of soil and/or groundwater samples, asbestos inspection and testing and lead based paint inspection and testing to name a few. Once samples are collected and tested, all disturbances to the property will be replaced.

When the on-site investigation is complete, and the laboratory results have produced the findings, a report is prepared detailing the results. The report will include sample locations, laboratory analysis and conclusions as well as recommendations for any additional work, if necessary.

InspectionIf additional work is needed for the removal of any identified hazards, United Analytical Services will generate a design document for the proper containment and removal. If the removal is related to soil or groundwater contamination, the United Analytical Services’ engineers can submit the appropriate documentation to the Illinois Environmental Protection Agency – IEPA for the purpose of reimbursement under Title XVI Rules and Regulations, or obtain a ‘No Further Action’ letter from the IEPA for the site under Title XVII Rules and Regulations.
