Skilled as an effective communicator, Mr. Cummins brings an understanding of state and federal environmental regulations and preferred problem-solving approaches. Remediation approaches implemented by Mr. Cummins include: soil removals, air/gas sparging networks, groundwater treatment systems, bioremediation procedures, insitu chemical oxidation (ISCO) and soil vapor extraction/dual phase extraction systems. He continues to monitor state-of-the-art remedial technologies as they evolve within the environmental community.


In the 30 years he has been in the environmental field, Mr. Cummins has managed a wide range of projects involving management of commercial UST Systems, supervision of commercial UST replacement, implementation of dewatering & treatment systems, subsurface contamination assessment, hydrocarbon recovery, water treatment system design and installation, and aquifer restoration. His experience includes the supervision of drilling and monitoring well installation, aquifer monitoring and contaminant transport modeling, hydrogeological assessments, compilation and interpretation of all geological data, and the design and implementation of innovative, customized remedial systems which often include multiple technologies working symbiotically to expedite site clean-up and closure.


Mr. Cummins has extensive knowledge of several geotechnical techniques including Standard Penetration Tests, ASTM 1586 and Shelby Tube sampling; has supervised conducting of rock cores for structural engineering design of underground and above ground structures; has supervised installation of structural caissons and sheet piling; is familiar with interpreting Electro-Magnetic Surveys, Ground Penetrating Radar and subsurface conductance surveys for the location of USTs, lagoons and subsurface burial sites. Mr. Cummins was also involved in the set-up and break-down of seismic wave collection devices used in oil exploration.


Mr. Cummins guides the development of new standard operating procedures and upgrades to existing programs as technologies and regulatory requirements evolve. He maintains company-wide quality assurance/quality control (QA/QC) measures on geoscience services. This is done in part through his staff in conducting project design and reports, and technical review on all documents submitted to the company's clients. In directing the company's active site audit system and technical projects tracking system, he ensures QA/QC standards for project management, field sampling, and remediation system operations.
