Well siting, design, permitting, installation and testing
Staff at ECS have completed numerous supply well projects in Coastal Plain, crystalline-rock and karst environments. Our approach is based on site location and project-specific details and can include a literature review, fracture trace analysis, geophysical electrical resistivity surveying, well siting, well design, well installation, well testing and water quality sampling.
Aquifer testing
ECS is adept at completing aquifer testing to characterize aquifer conditions and evaluate well performance. Our skilled staff are experienced performing pumping tests and slug testing (solid slug and pneumatic) in a variety of geologic settings and hydrogeologic conditions. Findings from aquifer testing can be used to characterize aquifer conditions that can impact long-term well performance and to estimate a well’s long-term sustainable pumping yield.
Numerical groundwater modeling
Groundwater modeling is a useful tool that can provide insight into impacts associated with a planned stress to a groundwater system. Numerical groundwater models can be applied to a variety of applications, including construction-dewatering projects; mining-related groundwater and surface water impact assessments; mine reclamation pit-filling evaluations; supply well impact assessments for industrial, municipal and community residential wells; shallow groundwater drain-design projects; stream-reconfiguration evaluations and groundwater mounding assessments.
Supply well feasibility assessments
Understanding the hydrogeologic environment, well yield potential, contaminant risks and permitting requirements is a critical preliminary step toward achieving a successful and cost-effective well installation project. Findings from these evaluations provide the client with information that can be used during the planning phase of a project to identify an aquifer target, create a preliminary well design and generate budgetary costs for well installation and testing.
Municipal groundwater resource evaluations
Understanding a municipality’s groundwater resources is the first step toward proper management to prevent future water scarcity or quality problems. Our clients’ municipal groundwater resource evaluations have been incorporated into county comprehensive management plans to help municipal officials make informed water supply decisions.
Construction dewatering evaluations
Urban construction dewatering projects often require the management of contaminated shallow groundwater, which can significantly increase project costs. ECS quantitatively evaluates aquifer characteristics in comparison to dewatering system designs to estimate dewatering pumping rates. Findings from these evaluations can be used to estimate construction dewatering rates and aid in the design of an on-site water treatment system.
Groundwater mounding studies and seepage assessments
Our experts are skilled at completing groundwater mounding evaluations to estimate mounding associated with planned stormwater-retention structures or septic systems. We are qualified to assess systems ranging in complexity and apply a suitable modeling approach to meet project needs. ECS also offers seepage assessments to determine the source and cause of seepage-related problems associated with retaining walls, subsurface building levels and subgrade stormwater distribution systems.
Groundwater monitoring
ECS has numerous ongoing long-term groundwater monitoring projects that involve collecting groundwater level and water quality data using a variety of monitoring and sampling techniques. ECS is adept at designing monitoring and sampling plans using state-of-the-art instruments to provide defensible data that meets project-specific objectives.
