- About CEC
CEC provides a full range of groundwater services, including investigations, hydrogeologic assessment, aquifer testing, quarterly monitoring, modeling, and site remediation. We have conduct groundwater studies to determine the nature and extent of aquifer contamination and to delineate plume boundaries, evaluate remediation alternatives, develop conceptual and numerical models, implement and monitor cleanups, and perform routine monitoring.
CEC provides a full range of groundwater services, including investigations, hydrogeologic assessment, aquifer testing, quarterly monitoring, modeling, and site remediation. We conduct groundwater studies nationwide to determine the nature and extent of aquifer contamination and to delineate plume boundaries.
Such studies generally require the design and installation of a monitoring well network, collection of samples, evaluation of groundwater flow and aquifer properties, and often modeling of groundwater flow and solute transport. We also develop plans and participate in negotiations with regulators to arrive at the most cost-effective solutions for our clients.
Data Acquisition and Analysis
CEC has extensive experience in the installation of monitoring wells and collection of groundwater samples in a variety of geologic settings, regulatory environments, contaminant scenarios, and project types. Our capabilities include the acquisition and statistical analysis of data to fully characterize groundwater conditions. We can perform large-scale pumping tests to predict the long-term yield and effectiveness of groundwater extraction networks, or more limited testing when appropriate to the project.
We use statistical analysis to quantify specific aquifer properties and long-term trends to understand the source, transport, and migration of groundwater contaminants.
Groundwater Resources and Modeling
Our highly trained and experienced hydrogeologists employ groundwater modeling and other investigative and quantitative approaches to address groundwater issues.
For groundwater resources projects, CEC has experience in performing hydrogeologic investigations and exploration, aquifer testing and evaluation, groundwater modeling, well field siting and expansion projects, existing well field evaluation studies, and wellhead protection plans and studies.
CEC has an extensive library of advanced computer models to simulate onsite groundwater conditions and predict movement of groundwater and chemical constituents through the groundwater system. We use combined flow and contaminant-transport models that permit evaluation of well placement, drains, pumping rates, source remediation, slurry walls, and other groundwater controls.
Pumping Well and Network Design
CEC's experience includes the design of groundwater-withdrawal networks, using either drains or pumping wells in both unconsolidated and bedrock aquifers. We design of extraction points based on site geology, well efficiency, anticipated pumping rates, and drawdowns.
