Geo-Logic’s extensive hydrogeologic experience includes design, construction, sampling, and evaluation of hundreds of water quality monitoring systems and over a thousand monitoring points.  Our familiarity with Federal and State water quality regulations is regularly updated through both regulatory agency interaction and continuing education.  All standard of practice sampling protocols and chain-of-custody procedures are implemented by a staff of highly-qualified environmental sampling specialists who have extensive experience in a variety of sampling projects.  In evaluating monitoring data, Geo-Logic utilizes statistical software developed in-house to generate objective conclusions with regard to known or suspected impacts.  We take pride in our comprehensive and easy to read report format that allows both the layman and the technician to understand and interpret the results.

Site Characterization

Environmental characterization is often complex and requires a thorough understanding of investigative techniques, analytical methods, hydrogeologic principles and mitigation alternatives.  Geo-Logic takes great pride in its history in environmental engineering; a history full of innovation and problem-solving.  Our innovative and proactive approach is typified by the in-house development of a statistical software package that permits a comprehensive evaluation of analytical data, as well as our use of practical mathematic models to simulate geologic structure, groundwater flow and contaminant fate and transport.  This information is used to select a mitigation alternative that best reflects the risks associated with known conditions and results in cost-effective and environmentally protective solutions.

Geo-Logic provides a complete range of environmental services from full characterization of surface water, vadose zone and groundwater to siting and design of long term monitoring systems.  Work has included extensive evaluations of vadose zone and groundwater systems in complex environments (including multiple aquifer systems), definition of the vertical and horizontal extent of environmental impacts, assessment of dilution/attenuation relationships, and development of databases that permit selection of the most appropriate remedial response.  These projects have typically involved monitoring well design and installation; groundwater, vadose zone and surface water monitoring, sampling and analyses; aquifer testing; geophysical analyses; numerical modeling; treatment plant design, and pilot and full scale treatment system construction and operation.

Mitigation and Remediation

Geo-Logic, in association with our affiliate Bryan A. Stirrat & Associates, has designed, installed and operated site-specific mitigation systems including air sparging, vapor extraction, groundwater extraction and treatment, slurry wall cutoffs, and low permeability barriers.  We have also successfully obtained regulatory approval for no action/continued monitoring programs at sites where the risks associated with the known release are not significant.  Geo-Logic’s mitigation recommendations are presented only after site specific interpretation of governing regulations and development of a thorough understanding of local geologic and hydrogeologic conditions, actual impacts and associated risks, and available mitigation technologies.
