Environmental Assessment and Remediation
Remediation Services, Phase I and Phase II
The definition of remediation is action to reduce, isolate, or remove contamination with the goal of preventing exposure to people or the environment. Troy Risk's engineers use the latest technologies for environmental remediation design. Our experience ranges from clean up of petroleum contaminants, such as leaking underground storage tanks (LUST), to industrial solvents including Tetrachloroethylene (PCE) and other chlorinated volatile organic compounds (CVOCs).
Some of our strategic remedial solutions include:
- Vacuum Extraction Systems (including soil vapor extraction and dual phase extraction)
- Free Product Recovery
- Reductive Dechlorination
- Risk Management
- 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 in an efficient and cost-effective manner.
Phase I Environmental Site Assessments
A Phase I Assessment Report identifies environmental conditions concerning the property land and buildings.

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 levels 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 groundwater monitoring wells.
The Phase II report can be relied on to resolve environmental conditon questions.
