Hydrogeologic and Groundwater Services
Expert Solutions for Water Supply and Groundwater-flow Projects
ECS provides a broad range of hydrogeologic and groundwater services and has the technical capabilities to apply sound strategies to complex groundwater-related projects. We have demonstrated experience working for industrial, commercial and municipal clients on projects located throughout the US in a variety of hydrogeologic environments.
Why ECS for hydrogeologic and groundwater services
Our team of hydrogeologists aid clients faced with challenging water supply and groundwater flow projects. We pride ourselves in our ability to provide a high level of technical ability and service on projects related to high-yield supply wells, well design, well testing, groundwater impact evaluations, groundwater modeling, advanced geospatial analysis and much more as part of our comprehensive hydrogeologic services.
Noteworthy hydrogeologic and groundwater projects include:
- Groundwater resources evaluation, Stafford County, VA
- Municipal well design, installation and testing, Urbanna, VA
- Groundwater modeling assessment for a municipal stream reconfiguration project, Charleston, SC
- Hydrogeologic evaluation and groundwater modeling assessment of the River Point Construction dewatering site, Washington, DC
Well siting, design, permitting, installation and testing
ECS has 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 tests (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 an important 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 region’s groundwater resources is the first step toward proper management to mitigate future water scarcity or quality problems. ECS has performed groundwater resource evaluations that have been used by municipalities to gain a better understanding of their groundwater resources. These 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 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.
Seasonal high water table determinations
ECS soil scientists provide seasonal high water table (SHWT) determinations to establish the peak elevation of subsurface groundwater fluctuations in a given area. Soil-based evidence is utilized to identify and interpret SHWT indicators within the soil profile. SHWT determinations also provide important information pertaining to the suitability of the soil type for project use, based on specific properties and characteristics of the soil and identify potentially restrictive qualities that could impact water movement through the soil profile. The SHWT determination findings are commonly provided to engineers for designing stormwater control measures (SCM).
