Environmental Assessment & Remediation Service

Some of our strategic remedial solutions include:

• Vacuum Extraction Systems (including soil vapor extraction and dual phase extraction)
• Free Product Recovery
• Reductive Dechlorination
• Chemical Oxidation
• Excavation, Transportation and Disposal of Contaminated Soils
• Air Sparging, Stripping (Pump and Treat) and Bioventing Systems

Based on the chemicals of concern, land use and site geology, Troy Risk utilizes the remedial technology which best suits each site. With the skills and experiences of our geologists, hydrogeologists and environmental engineers, we clean up contamination.

The purpose of a Phase II investigation is to determine whether the property is actually impacted at levels that exceed regulatory action levels. In Indiana, these are established by the Indiana Department of Environmental Management (IDEM). When appropriate, IDEM`s RISC program has established default residential and industrial levels of environmental impact in soil and groundwater – beneath which the impact poses negligible health risk to users of the property.

Troy Risk specializes in Phase II Subsurface Investigations of soil and groundwater. We have the field investigation and analytical technologies which test for chemicals on-site and collect samples for analyses by an environmental laboratory.

Troy Risk collects and assesses Phase II samples by a variety of methods such as:

• Geoprobe direct push soil and groundwater sampling equipment
• Mobile laboratory
• Surface grab sample
• Shallow hand auger sample
• Backhoe sampling
• Soil gas sampling
• Groundwater monitoring through the installation of temporary and permanent groundwater monitoring wells.

Troy Risk’s Environmental Professionals perform Phase I Environmental Site Assessments (ESA) using ASTM Standard Practices to identify potential or existing environmental contamination liabilities. The Phase I ESA typically addresses both the underlying land as well as physical improvements to the property. The Phase I site inspection includes examination of potential soil contamination, groundwater quality and surface water quality through a site inspection and review of the property’s history. The examination of a site includes:

• Inspecting the property.
• Identifying past use of the property during time of ownership.
• Definition of any hazardous waste or petroleum storage.
• Review of waste-handling procedures.
• Interviews with past property owners, employees or neighbors.
• Review of regulatory databases that list contaminated sites and historical sources.
• Review of adjacent properties to evaluate potential sources of off-site contamination.
• Review of aerial photographs of the site.

The Phase I ESA is generally considered necessary in the due diligence process. Troy Risk performs Phase I Environmental Site Assessments to meet the following standard practices accepted by State regulatory agencies, the U.S. EPA and U.S. banks:

• U.S. EPA Final Rule for All Appropriate Inquiry
• ASTM E1527 -05 Standard Guide for Phase I Studies

Troy Risk`s assessors meet the ASTM E1527 -05 definition of Environmental Professional. The ASTM defines an Environmental Professional as someone with:

1. A current Professional Engineer’s or Professional Geologist’s license, or registration from a state or U.S. territory with 3 years equivalent full-time experience.
2. A Baccalaureate or higher degree from an accredited institution of higher education in a discipline of engineering or science and 5 years equivalent full-time experience.
3. The equivalent of 10 years full-time experience.

If recognized environmental conditions exist, a Phase II Environmental Site Assessment may be conducted, which is a more detailed investigation involving chemical analysis for hazardous substances and/or petroleum hydrocarbons.
