Hydrogeologic and Groundwater Services

ECS provides a range of hydrogeologic services and has demonstrated experience working for industrial, commercial, and municipal clients on projects located throughout the United States in a variety of hydrogeologic environments. ECS provides municipal drinking water source and feasibility testing, including large-scale hydraulic testing intended to demonstrate whether the well or well field can support the current and long-term growth needs of the community.

Our hydrogeologists can provide assistance to clients faced with challenging water resource or groundwater flow projects.  We pride ourselves in our ability to provide a high level of technical ability and service on a variety of projects related to high-yield supply wells, well testing, groundwater impact evaluations, construction dewatering, groundwater modeling, advanced geospatial analysis, etc.

ECS is happy to support your hydrogeologic project needs. Please contact us or email us at hydrogeologic@ecslimited.com and let us know how we can help.

Well Siting, Permitting, Installation, and Testing

Completed for industrial, municipal, commercial, and community residential clients requiring a high-yield supply well.  Typically involves a literature review, fracture trace analysis, geophysical electrical resistivity surveying, well siting, well installation, well testing, and water quality sampling

Pumping Testing, Slug Testing, and Data Analysis

Testing that is commonly used to assess aquifer properties and other aquifer conditions for the purpose of estimating long-term well yields or groundwater impacts resulting from the application of a system stress.

Groundwater Quantity and Quality Suitability Studies

These studies are often completed as a preliminary feasibility assessment to evaluate a region or site’s water resource potential.  Findings can be used to guide future well siting activities. 

Numerical Groundwater Modeling

Groundwater modeling is a useful tool that can provide insight into impacts associated with a planned stress to a groundwater system.  ECS has completed numerous numerical groundwater models for a variety of applications, including for construction dewatering projects, mining-related groundwater and surface water impact assessments, mine pit reclamation pit filling evaluations, supply well impact assessments for industrial, municipal, and community residential wells, shallow groundwater drain design projects, and groundwater mounding assessments.

Dewatering Evaluations

Evaluating dewatering system designs and pumping rates through the completion of a numerical groundwater model is an integral part of the planning process at urban construction, mine, and industrial sites requiring the implementation of dewatering activities.

Mounding Studies

Completed to estimate groundwater mounding associated with planned stormwater retention structures or septic systems.

Seepage Assessments

ECS has completed a variety of seepage assessments to assess the source and cause of seepage-related problems associated with retaining walls, subsurface building levels, and subgrade stormwater distribution systems.

Municipal Groundwater Resource Evaluations

Groundwater is becoming an increasingly important resource that must be managed properly to prevent future water scarcity or quality problems.  Understanding a municipality’s groundwater resources is the first step toward properly managing this important resource.  ECS has experience completing municipal groundwater resource evaluations that have been incorporated into County Comprehensive Management Plans to help residents and municipal officials alike make informed water supply decisions. 

Groundwater Impact Studies

Groundwater impact studies are an important planning tool that can provide a business or regulatory agency with the ability to assess impacts to the groundwater system, surface waterbodies, and/or proximal supply wells prior to initiating a proposed stress to the system.  

Coastal Plain Supply Well Feasibility Assessments

Groundwater is a crucial resource in the coastal plain regions of the United States, where large numbers of residents, municipalities, and businesses depend on this resource as the primary source of water.  ECS can help navigate the complexity of coastal plain aquifer systems and supply well permitting through the completion of Supply Well Feasibility Assessments.  These assessments provide clients with information pertaining to aquifer targets, anticipated drilling depths and well yields, water quality, permitting requirements, drilling costs, and other important considerations when planning a coastal plain supply well.   

Groundwater-Surface Water Interaction Studies

These studies allow for the evaluation of how a planned change to the groundwater system, such as a supply well or mine, may impact proximal surface waterbodies.

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.  

Capture Zone Analysis

Completing a capture zone analysis for a supply well or spring allows the source owner to better understand and mitigate potential contaminant sources that could impact their water supply.
