KEMRON held a master service agreement with a Class I railroad for more than 10 years completing more than 200 projects. KEMRON completed a wide range of environmental services to include site investigations, engineering studies and remediation programs at railyards; removal of USTs from active and inactive railyards; emergency response to derailment/spill sites; preacqusition and divestiture audits; corrective actions; and large remediation in support of redevelopment. Representative experience includes:
Nationwide Tank Program. Under contract to the client, KEMRON removed over 300 USTs at various rail facilities throughout the eastern United States. Project activities included initial notification, site assessment, tank removal, free product recovery, soil remediation, soil and groundwater investigations and continuing investigative and remedial services necessary to achieve clean closure of each tank pit according to state guidelines.
Port Covington. KEMRON conducted a $7.5 million turnkey investigation and remediation of Port Covington site in Baltimore, MD, a 189-acre former railyard and port facility, for Brownfield redevelopment into a marina, hotel, office park and a newspaper’s printing plant/office complex. KEMRON conducted a preliminary assessment/site investigation to determine the extent and type of contamination. KEMRON developed remedial goals to address levels of arsenic, cadmium, lead, petroleum hydrocarbons and volatile organics found on site. KEMRON conducted a remedial investigation and feasibility study.Following selection of remedial options, KEMRON then implemented a large remediation program including: removal of surface refuse piles, emptying of septic tanks, removal of 200 drums of unknown contents, removal of contaminated soil from maintenance buildings and decommissioning/closure of 30 fuel storage tanks. KEMRON completed long term remedial actions using bioremediation of over 50,000 yards of contaminated soil and stabilization/fixation of 20,000 yards of lead contaminated soil.
Barr Yard. KEMRON conducted a comprehensive soil and groundwater investigation at the locomotive fueling facility located at a rail yard in Chicago, IL. Petroleum contamination was identified throughout the fueling area and was encroaching onto other areas of the rail yard. KEMRON developed a product recovery and soil remediation program integrated it into the engineering plans for upgrading the fueling area. The design/build solution developed and implemented consisted of the installation of a series of recovery trenches, installation of five lift stations, installation of 480 feet of horizontal wells and removal and disposal of contaminated soils.
Ellicottville, NY. KEMRON conducted a surgical removal of zinc ore from a train derailment incident. Box cars containing zinc ore derailed spilling the ore along several hundred feet of track bed in Ellicottville, NY. After the majority of the spilled material was removed, KEMRON performed a site investigation of the residual metals, contaminated track bed, and adjacent farmland. Cadmium, a secondary component of the ore, was of concern to the regulators. The KEMRON team conducted a risk evaluation of the cadmium contamination in three distinct environments – limited access railroad trackage, resort development property, and agricultural land. The remedial action plan included three remedial approaches; each tailored to the particular risk and concern of each environment contaminated.
Eckington Railyard. KEMRON conducted a comprehensive environmental and hydrogeologic evaluation of a former rail yard and three nearby parcels in Washington DC to determine if contamination existed from prior usage which would preclude redevelopment of these parcels for commercial use. A site history records search was performed and historical aerial photographs were reviewed. Remedial clean-up levels were negotiated with the District of Columbia Environmental Agency. KEMRON also surveyed onsite buildings for Asbestos.

KEMRON has been providing environmental services to Hartsfield Jackson Atlanta International Airport to include compliance audits, remediation, investigation, pilot studies, tank removals, excavation, air monitoring and groundwater monitoring. KEMRON is a primary subcontractor on an Environmental Contract for this airport and has completed a variety of projects covering Environmental Sampling, Regulatory Evaluation and Management, Field Surveys, Remediation, and Preparation of Environmental Reports
Examples of work completed under this contract include:
Remediation Field Testing. KEMRON conducted remediation field testing including: conducting soil vapor extraction (SVE) tests, conducting high-vacuum, multi-phase extraction tests and reporting of results. The field testing included collection of pre-test groundwater and free product levels from eight groundwater monitoring wells and one product extraction well. The specific data objectives included the soil-air permeability and potential effectiveness of high-vacuum, multi-phase extraction for product recovery.
The high-vacuum, multi-phase extraction test was conducted to assess the potential effectiveness of this technology for future free product removal. The test was conducted on the existing product recovery well, which has been observed as containing a product thickness of 10 feet. Data collected during the test included vacuum measurements for groundwater monitoring wells and groundwater/free product level data from all wells following the test. Air flow and total hydrocarbon measurements were recorded along with estimates of product and groundwater recovery.
Free Product Recovery and Pilot Testing. KEMRON performed free product recovery at Pit # 19 using the KEMVAC system. KEMVAC is a proprietary dual-phase vacuum extraction and thermal oxidation system developed by KEMRON. A JP4 fuel lead occurred in the hydrant fueling system producing free product on groundwater. The leak is located at gate A19, the busiest location at the airport. KEMRON performed a one-day, high vapor, multi-phase extraction pilot test. The objective of pilot test was to determine if this remedial technology is a cost-effective solution for cleanup of this high traffic volume site.
Environmental Compliance Audits. KEMRON provided consulting services to the airport’s Department of Aviation (DOA) to perform a multi-media environmental compliance audit of airport tenants. Three auditing teams, consisting of three individuals with varied compliance backgrounds, performed the environmental compliance audits over a three-month period in 2003. The multi-media environmental compliance audit encompassed the following areas of concern: Chemical Product Importation, Oil Pollution Control and Contingency Planning, Spill Response and Release Reporting, USTs, Wetlands, Hazardous Materials Management, PCBs, Solid and Hazardous Waste Management, and Water Quality.
Each environmental compliance audit was completed by utilizing a three-step process. A pre-audit questionnaire was either picked up by the tenant or mailed to the tenant at least one month prior to scheduling the audit. A site visit and records review was scheduled with the environmental coordinator or manager of each tenant at least one week in advance. A site visit and records review was performed including an exit meeting with the tenant to discuss potential areas of concern identified during the audit.
A summary memorandum was generated to summarize audit findings for each tenant. The summary memorandum was forwarded to the DOA Environmental Projects Manager and the tenant representative. Tank Tightness Testing. KEMRON performed UST tightness testing for four underground storage tanks and associated piping; two (2) 600 gallon USTs located at building 6 fuel island and two 12,000 gallon USTs located at building 4 fuel island at HJAIA.

KEMRON conducted Phase I and Phase II Environmental Due Diligence Audits (EDDA) as part of this engagement for this airport client. The EDDA is required by the FAA for acquisition and disposal of real property at aviation facilities, to minimize the FAA’s environmental liabilities. KEMRON conducted the Phase I EDDA for over 400 acres of property.
The airport lies between residential and heavy industrial communities, and has been in operation for over 70 years. During the course of conducting the EDDA, KEMRON collected information from over 30 regulatory agencies and affected parties. All available historical documentation regarding site environmental issues was researched, reviewed, summarized, and catalogued. KEMRON then completed a comprehensive site reconnaissance, walking all areas encompassed by the EDDA and documenting existing site conditions and any potential environmental concerns. In addition, KEMRON was responsible for completion of all requirements pertaining to wetlands, threatened and endangered species, cultural and historic resources and biotic communities, per NEPA and DOT requirements.
Based upon this comprehensive document review and site reconnaissance, the EDDA revealed over 20 separate potential areas of environmental concern, including former USTs, hazardous waste units, solid waste disposal sites, contaminated soil management issues, and numerous potential releases of hazardous substances.
Subsequent to completion of the Phase I EDDA, KEMRON designed and implemented work plans for site investigation of environmental issues through a Phase II EDDA. KEMRON was responsible for development of the technical approach to assessment, preparing site specific health and safety plans, implementation of the plans, and report preparation.
Work completed during the Phase II EDDA included installation of test pits, field screening and field testing of soil and waste materials, geoprobe investigations and extensive soil sampling and analysis for petroleum products, volatile and semivolatile contaminants. The Phase II EDDA field investigations evaluated all areas of concern identified during the Phase I.
Results of the Phase I and Phase II EDDA were compiled into a comprehensive five volume report of findings which included catalogued reference materials, original CADD mapping, analytical data, and interpretative summaries. All documents were also supplied to the client in electronic format for archival purposes.
KEMRON was contracted to perform environmental sampling of nine surface water outfalls and two instream monitoring locations to evaluate compliance with the Airport’s NPDES permit requirements. KEMRON also performed sewer sampling under the airport’s Comprehensive Sampling and Analysis Program (CSAP). KEMRON personnel responded within 12-24 hours of special requests and on regularly scheduled intervals to perform environmental sampling. The NPDES surface water sampling and analytical results were used to determine compliance with the NPDES permits.
For the airport’s CSAP sampling events, KEMRON personnel participated in identification of sewer manholes and catch basins using existing drawings of the airport sewer system. KEMRON personnel employed the drawings and field reconnaissance notes to determine appropriate sampling points, and conduct sampling within the sewer system.
Field activities are conducted both airside and landside. KEMRON personnel were available to work flexible schedules to accommodate needs for sampling events occurring during both day and night hours. Airside sampling was conducted in close coordination with airport personnel and in compliance with all FAA requirements to ensure that air traffic is not interrupted or impacted by the sampling activities, and that safety is ensured throughout each sampling event.
