Ground Water Withdrawal Analysis and Permitting

 

Keeping Your Project in the Pipeline

Whether you are a municipal water supplier or a business developer beginning construction on a new project, water resource permitting can present a significant hurdle. GeoInsight engineers and hydrogeologists work with municipalities, water suppliers, and businesses throughout the northeast to tackle these complex permitting projects, delivering the favorable outcome your project needs to move forward.

Our Regulatory Ties Are Your Advantage

We have worked hard to develop a reputation for unbiased and technically rigorous hydrogeologic and engineering studies that consistently pass the scrutiny of local development boards, public utilities commissions, and state and federal environmental regulators. You will benefit from our strong reputation with state regulators, which allows us to work through your “hot button” items, preventing unexpected permitting holdups. 

 

GeoInsight’s Ground Water Withdrawal and Permitting Services Include:

GeoInsight uses the latest geologic mapping and geophysical techniques including fracture trace analyses, seismic evaluation, and electrical resistivity to help you find the water you need. Our years of experience with the expected performance of ground water aquifers in our region help our clients evaluate potential well sites and withdrawal system configurations.

Our engineers and hydrogeologists have worked on designing wells in a wide variety of geologic environments including large capacity/large diameter gravel pack wells, deep wells in fractured bedrock, and specialty wells such as caisson wells for stream bed recharge applications. Our range of experience is highly beneficial to devising creative solutions to meet water supply needs.

Your supply needs to be protected from threats and setbacks from sensitive features. GeoInsight uses geographic information system (GIS) technology to quickly prepare illustrations that identify buffers for streams, wetlands, wastewater systems, potential contaminant sources and other pertinent features the could constrain the development of a wellfield.

We construct comprehensive withdrawal testing plans, collecting data to evaluate potential interactions with nearby water supplies or water resources. Plans commonly include extensive water-level monitoring to track changes induced by withdrawal testing. GeoInsight hydrogeologists interpret and present pump testing data: evaluating sustainable well yields, the possible impacts of withdrawals during drought conditions, and capture zones around a well.

As an expert in the water supply field, GeoInsight is often asked to conduct peer reviews of withdrawal testing plans for concerned water users and stakeholders, verifying that potential adverse impacts are properly evaluated and addressed. GeoInsight staff members have served on legislative committees and routinely conduct training seminars for local water works associations. 

To aid with your permitting efforts, we routinely use various software packages to evaluate pumping captures zones to refine conceptual models including:

  • Analytical ground water flow models
  • Finite difference ground water flow models (MODFLOW)
  • Analytical packages such as AT123D (contaminant flow)
  • Natural Attenuation Software (natural decay of contaminants), and
  • Seasonal Soil Compartment Model (leaching of soil constituents).

 

In many cases, analytical methods are sufficient to completely address your project’s challenges. In more complex, high-stakes projects, we've constructed detailed finite difference models (such as MODFLOW) to account for complex hydrogeologic environments or to address especially sensitive receptor situations.
