Hydrogeology and Remediation Services- Brochure

Hydrogeology and Remediation ServicesCost-Effective Groundwater and Subsurface SolutionsCornerstone’s Hydrogeology group specializes in providing groundwater and other subsurface related services that re-sult in cost-effective solutions. Our experience includes both operating and inactive landfills, industrial facilities, aban-doned hazardous waste sites, and commercial facilities. We have the capabilities to address every phase of the project, from initial site characterization through post-remediation compliance monitoring. Cornerstone provides a full spectrum of services tailored to accommodate the size and complexity of any site. Our ser-vices have addressed a wide range of contaminants, includ-ing volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), manufactured gas plant (MGP) wastes and metals, as well as both dense and light non-aqueous phase liquids (DNAPLs and LNAPL).What Sets Cornerstone Apart?• Integrating hydrogeology and engineering - We under-stand that site characterization and its relationship to engineering design is key to success.• Creative, customized approaches - Our experts are skilled at developing focused investigations that target key data necessary to achieve project objectives and/or site use goals.• Groundwater flow and transport modeling expertise - We are skilled in the art and science of using numerical mod-eling to simulate the dynamic processes of groundwater flow and contaminant transport.• Data management and visualization expertise - Corner-stone uses innovative visualization techniques to display model results and data to support project objectives.• Nationwide presence - Offering both regional perspective and knowledge of the local geology gained by working with local drilling contractors.Building lifetime relationships with our clients and employeesHydrogeology Services ProvidedSite Investigations• Cornerstone conducts thorough yet focused site inves-tigations to attain economically sensible cleanup strate-gies to improve efficiency and reduce costs. Examples of techniques used to improve efficiency and reduce costs include Simulprobe samplers for simultaneous collection of soil and groundwater samples with real-time ground-water analyses; water FLUTe systems in bedrock well installations to provide cost-effective multi-depth sam-pling ports in a single open borehole; and development of a real-time data management system in combination with GIS to quickly compare soil data to cleanup criteria.Groundwater modeling• Our nationally recognized hydrogeologists and engineers each have more than 30 years of groundwater modeling experience, ranging from simple, analytical based pro-grams to fully three-dimensional numerical codes sup-ported by graphics-based pre- and post-processors.Water supply services• Cornerstone’s water supply capabilities cover the entire process, from the initial hydrogeologic investigation to the design and testing of production wells, to the permit-ting of both supply wells and treatment systems.Data management/GIS• Closely aligned with Cornerstone’s data collection capabil-ities is the ability to compile, store and display these data in an efficient way. Using databases like Microsoft Access and GIS applications such as Arcview, data are easily man-aged in a variety of innovative ways to support project objectives.Data visualization• Cornerstone’s visualization capabilities include anima-tions with and without voice-overs, web-based interfaces, three-dimensional displays, and GIS. Data can be depicted as contours, with or without color-shading, or iso-surfaces. Model results can be displayed in plan view, cross-section, or in three dimensions.Support services• In addition to the technical services described above, Cornerstone has extensive experience in agency negotia-tions, public participation, and litigation support.Recent Cornerstone ExperienceCornerstone prides itself on establishing close and produc-tive relationships with its clients. A few recent examples of our hydrogeologic assignments include: Confidential Client (NJ) – Conducted investigations to define the extent of a groundwater plume of hexavalent chromium, including drilling, bedrock well installation, aquifer test-ing, sediment sampling and tidal studies. Also conducted groundwater modeling as part of groundwater containment remedy design.Wickham Water District (NY) – Identified and delineated a prolific shallow water-bearing aquifer within this primarily residential water district in southern NY. Installed, tested, and permitted a 250 gallon per minute potable water supply well to supplement the existing old and failing bedrock wells.Des Moines TCE Superfund Site (IA) – Conducted aquifer testing to define the complex relationship between ground-water and surface water along the banks of the Raccoon River and succeeded in reducing the EPA planned remedy to a manageable groundwater containment system.Nascolite Site PRP Group (NJ) – Conducted groundwater investigations and groundwater modeling for the design of a groundwater containment remedy that includes ground- water pumping, on-site treatment and re-injection into the aquifer.For more information contact:Willian Soukup, P.G. - (845) 695-0253 email info@cornerstoneeg.com or visit www.cornerstoneeg.com 05/14
