Landfill Monitoring:

GCI offers a variety of professional services to monitor and investigate the environmental impact associated with operating solid waste landfills. GCI can provide services to assess the environmental impact from a landfill, ranging from routine monitoring to extensive hydrogeologic investigations.

The professional staff at GCI has been involved in numerous environmental monitoring programs at solid waste facilities over the past 20 years. Projects have typically involved the design and implementation of monitoring programs in accordance with regulatory requirements, and have included collection of groundwater, surface water, leachate, domestic well, air and NPDES samples, with data reporting and analysis. Statistical analysis of water quality data is also available. We can provide data to you in either electronic or hardcopy form.

Our knowledge of State and Federal regulatory requirements for environmental monitoring at solid waste landfills can guide you through your regulatory problems.

GCI has extensive experience in the preparation of technical reports to evaluate environmental impact from municipal solid waste landfills in accordance with the state-approved environmental monitoring programs. In addition to summarizing the data, these reports evaluate historical data trends using time-series analysis, and use groundwater contour maps depict groundwater flow conditions.

GCI can conduct soil gas investigations to evaluate the nature and extent of landfill gas migration at solid waste landfills. GCI also has experience with a range of drilling methods including hollow stem auger, air rotary, mud rotary, direct push, or rock coring.

GCI can carry out aquifer testing to evaluate the hydraulic properties of a site. Our experience allows the selection of appropriate test methods for site conditions.

A GCI project manager is assigned to each project and is responsible for client communication, oversight of the field staff and field procedures, QA/QC procedures, selection and oversight of subcontractors, evaluation of data and reviewing any documents or reports.

Our quality control plan assures that collected data collected is valid and representative of actual conditions, and that the technical procedures used are in accordance with accepted practices and legally defensible. Our QA/QC plan covers field and laboratory procedures. The plan may include the collection of field blanks, trip blanks or blind duplicate samples. However, because this sampling adds to the cost of a project, the project manager can assist in balancing the need for quality control with the need to complete a project on budget.

All GCI field personnel have completed an OSHA 40-hr safety and health training course and attend annual safety and health refresher courses. GCI owns and maintains a range of environmental monitoring instruments, including explosimeters, oxygen meters and photoionization detectors, plus personal protective equipment.
