Environmental Services
Our Site Investigation Services:
Koehler Engineering is equipped with the tools, personal skills, and regulatory experience to conduct site investigations and contaminant hydrogeology. Our field investigations and reviews include the following activities:
-
Analysis and assessment of subsurface conditions by geotechnical drilling, geophysical surveys, or other subsurface sampling methods.
-
Evaluation and determination of direction and rate of groundwater flow.
-
Modeling of contaminant and transport.
-
Assessment of contaminant impact on groundwater supplies.
-
Evaluation and assessment of human exposure and risk assessment relating to contaminated soil and groundwater.
-
Development and assessment of groundwater remediation system design, operation and effectiveness.
Our Underground Storage Tank Closure Service:
Our services include managing the removal and remediation process as part of a comprehensive environmental closure approach by qualified registered professional engineers and geologists. Koehler Engineering is well-versed in State regulatory requirements, including regulations for the handling and disposing of USTs and associated waste materials. In the State of Missouri, we have completed closure projects in compliance with the Missouri Risk Based Closure Assessment (MRBCA) guidelines, as well as worked with the Petroleum Storage Tank Insurance Fund to ensure our work is performed properly and efficiently. Our focus is both to minimize environmental impacts from leakage of petroleum products into the soil and groundwater, and to control cost to our clients.
Our Phase 1 Environmental Site Assessment Service:
Phase 1 Environmental Site Assessment (ESA) reports are prepared by our registered professional engineers and geologist for real estate and business transactions such as: land purchases, building purchases, leases, business purchases, new residential developments, and bank loans. Our Phase 1 ESA reports adhere to American Society for Testing and Materials (ASTM) Standards and to the Environmental Protection Agency all Appropriate Inquiries Rule, codified into the federal regulations by EPA(40 CFR Part 312). This type of Phase 1 Environmental report is commonly required by lenders and is highly recommended prior to purchasing commercial or industrial real estate.
Our Phase 2 Environmental Site Assessment Service:
Phase 2 Environmental Site Assessment (ESA) reports are sometimes required when a Recognized Environmental Condition (REC) is found during the Phase 1 Environmental Assessment Process. Phase 2 ESA s consist of collecting soil and groundwater samples to screen for the presence of contamination. This sampling is conducted by drill rig, hydraulic push, hand auger, or backhoe, depending on site specific conditions. Phase 2 ESA s can also include sampling of groundwater and surface water. This testing is recommended when there is a potential for the existence of an environmental liability that can affect the value of a property.
Our Workplace Exposure Monitoring Service:
Koehler Engineering is currently working with industrial clients on workplace exposure monitoring for chemical and physical hazards. Our ABIH board-certified Industrial Hygienist (CIH) has extensive background in the environmental fields. We offer rapid response and real-time monitoring or, if laboratory analysis is required, we can typically provide 24 to 48 hour turn-around on samples.
Our Mold Inspection and IAQ Evaluations:
Independent Evaluation by a Certified Industrial Hygienist.
Our Certified Industrial Hygienist provides mold testing on a fast turn-around time frame. Our mold inspection and IAQ evaluations include:
-
Air quality testing for mold spores, particulates, allergens, and other contaminants in commercial and residential buildings
-
Evaluation of building for moisture accumulation that leads to mold growth
Our evaluation reports include both the results of the building evaluation and protocol for mold remediation.
