Phase I environmental site investigations are routinely conducted to support pre-development property transactions, developed property transfers, and site closures. Lending institutions, realty corporations, landholders, and private individuals must consider environmental contamination as a potential risk when considering properties for acquisition. Purchase of a contaminated property can result in assumption of significant cost for cleanup. To address this issue, purchasers of real estate consider an environmental assessment as a routine component of an acquisition.

McAlister GeoScience maintains very low overhead and straightforward contracting terms to accelerate turnaround times and reduce contracting headaches all at extremely competitive pricing.

Phase II environmental site investigations are performed to delineate horizontal and vertical extent of volatile organics, metals, petroleum hydrocarbons, and other chemicals of concern should a Phase I ESA find the potential for contamination. McAlister GeoScience has effectively managed field activities, coordinated with analytical laboratories, evaluated data, and prepared reports associated with ongoing groundwater monitoring programs in addition to more basic studies of shallow contaminated soils.

Technically sound and legally defensible solutions performed in a teaming fashion to meet regulatory requirements, schedule, and budget. If a property comes up dirty, McAlister GeoScience is there alongside you to ensure the problem is remediated. We have relationships with teams ready to assist you every step of the way from drilling, laboratory work, system installation & operation to regulatory compliance. At McAlister GeoScience we work for you and want to assist in turning a dirty problem into a clean solution.

For many properties, a full Phase I Assessment is overkill or otherwise not necessary.  A Technical Memorandum can be developed in an expedited time-frame at minimal cost to summarize the numerous information sources available.

Surveys and abatement performed by licensed experts in a teaming fashion.  All services provided on a turn-key basis with one point of contact for ease of management.

Planning a development? McAlister GeoScience provides geotechnical investigations necessary prior to the development of buildings, highways, dams and other structures. These include soil/rock, fault and bedrock properties that lie on the surface and within the subsurface. McAlister GeoScience is there to support the multiple phases of development from preliminary design through completion of the structure. As your consultant, we are there to make professional judgments and advise developers with necessary information regarding structural safety of the development as it relates to the soil conditions and economic feasibility of the project.

Property Condition Assessments (PCAs), also known as Property Condition Reports (PCRs), are due diligence reports prepared to inform clients about the condition of a property that they may be purchasing, leasing, financing, or maintaining. A PCA report consists of insight into the building’s structure, roofing systems, mechanical systems, electrical systems, plumbing, interior elements, etc. The report includes immediate costs of elements in need of repair and estimated costs for elements to be repaired or replaced at a later time.

Vapor intrusion poses a threat to indoor air quality when volatile organic chemicals, or VOCs, present in the property’s subsurface soil or groundwater seep into the building.

If a property is potentially impacted by vapor intrusion, several phases of investigation and remediation may be required.  During the initial due diligence phase of most commercial real estate transactions, a Phase I ESA, is performed to identify potential environmental impacts at the property, including indoor air quality. If a potential risk is identified such as a leaking underground fuel tank at or near the property, the recommendation is made to perform a Phase II ESA.

Each site is different and requires different engineering controls to mitigate subsurface vapors, such as a site using more modern concrete slab-on-grade construction techniques. It is imperative to hire a qualified environmental professional that can implement different methods depending on the building.

Another useful step is to collect subsurface soil gas and indoor air samples. However, this becomes challenging because fresh paint or carpet in the building can lead to false positives in the samples. If there are VOCs in the breathing zone of the building from subsurface contamination, we can implement building engineering controls, such as a venting system similar to what you would see to mitigate radon gas.
