Conceptual Site Models (CSMs)
Conceptual Site Models (CSMs) are a systematic planning tool used to identify potential sources of contamination associated with a site, possible biological entities that are susceptible to contaminant exposure, and the contaminant migration routes by which these entities could potentially be exposed. Supported by scientific and technical decisions, CSMs identify source-pathway-receptor relationships to identify data gaps in the characterization process by conceptualizing unknown environmental site issues and/or anticipating unexpected scenarios that may arise in the future. AGES uses data collected during field investigations to develop a CSM that is specific to each client's unique situation. A properly developed CSM can help reduce long-term costs by predicting unforeseen problems and providing foresight to plan accordingly during decision-making processes.
Visualization and Modeling
To help our clients anticipate unforeseen environmental project issues, AGES offers several three-dimensional modeling services, which have included lithological models, site-specific groundwater flow models, hydrogeological models, fate and transport models and unsaturated soil models for both private and public clients. We have a wide variety of mathematical and modeling tools at our disposal, which include: Leapfrog Hydro, GMS, MODFLOW, MODPATH, MT3DMS, RT3D, FEMWATER and PEST as well as simpler, less labor-intensive Domenico-based analytical models. The model must be matched to the problem and the available dataset, large or small.
Risk Assessment and Risk Management
Environmental Risk Assessments are performed to minimize adverse effects to humans and the environment and generally follow site assessments and remedial investigations. This is due to the fact that a successful Risk Assessment requires a thorough understanding of the site hydrogeology, contaminant chemistry, environmental fate and transport mechanisms, migration routes and exposure pathways. AGES brings a multi-disciplinary approach to our Risk Assessment/Risk Management practice through integration of our hydrogeology, chemistry, biology, modeling, vapor intrusion and statistical service areas. Our risk assessment team assists our clients in developing remedial strategies, minimizing remediation costs and implementing a risk management approach that permits impacted material to remain in-place; but provides protection for human health and the environment through exposure pathway elimination. AGES has successfully conducted risk assessments under the CERCLA, RCRA, Ohio Voluntary Action Program (VAP), Pennsylvania Land Recycling Program (Act 2), West Virginia Voluntary Remediation Program (VRP), Indiana VRP and other state programs.
Cost models are an effective tool to develop budgets for larger projects and allows clients to make sound business decisions. Based on structure, knowledge and current technology, cost models closely examines engineering requirements and competitive business pricing. AGES has over 20 years of experience in the cost modeling arena and have helped Fortune 500 clients make successful organizational decisions.
Homeowner Analytical Results Evaluation
Due to scientific language, symbols, and acronyms, analytical lab results are difficult to interpret and the presentation of the results varies from laboratory to laboratory. This is why AGES offers a homeowner analytical results evaluation service. AGES will have a qualified hydrogeological professional review the analytical results provided to landowners by natural gas drilling companies or other third-party sampling professionals. Hiring AGES to review sampling results allows for independent measure and documentation of trends and impacts, as well as assistance in ensuring that proper sample handling, preservation and shipment protocols were followed by the sampler. Afterwards the evaluation, AGES can assist with management of the sampled water source.
