SERVICE - geoscience assessment

Proper Assessment for
Permit Issuance


Conducting a proper geoscience assessment of your site to understand what lies beneath the ground is critical to the timeline and success of your project and is often required for permit issuance. Our investigations are designed with your end goal in mind, to collect the data crucial for your project and ensure compliance with applicable environmental regulations. We can help you navigate today’s increasingly complex regulatory environment to achieve your end goals. 


Our diverse experience across multiple industries and technical disciplines provides unique problem-solving capabilities and resources for your project.


At EARTHRES, we routinely provide the following hydrogeologic services for the successful development of our client’s projects:

── Analysis and Assessments
  • Hydrogeologic Investigations, Mapping, and Assessment
  • Water Supply Permitting and Resource Development
  • Aquifer Assessments
  • Source Water Assessment
  • Contaminant Fate and Transport
  • Groundwater Sampling and Monitoring
  • Wetland Hydrology Evaluation
  • Database Development and Statistical Data Analysis

Before and during the development of a site, you may be required to conduct an environmental investigation and remediation if there are environmental impacts to soil, water, or air.

These impacts could be due to historical use of hazardous materials at the site or nearby sites. From offering services ranging from Phase I Environmental Site Assessments (ESA) to remediation, our talented team at EARTHRES will complete investigation(s) tailored to your plans for the site, and often in a phased manner to control costs. During this process, we will provide and communicate strategic remediation recommendations for the successful development of your project. Whether it is surface water, groundwater, soil, or vapor, we will evaluate the extent of existing or probability of potential IMPACTS using the latest techniques, models, and analytical methods.

In addition, and when required, we partner with you to develop and negotiate work plans for the U.S. EPA and PADEP and then implement those work plans to your satisfaction. Through proper design, planning, and implementation, we can turn your vision into reality.

── Investigation and remediation services include:
  • Phase I and II Environmental Site Assessments (ESA) to ASTM AAI Standards
  • Brownfields Investigations
  • Pennsylvania Act 2 investigation and reporting
  • Site characterization
  • Pilot testing, remedial alternatives analysis, selection, and design
  • Remediation and post-closure monitoring programs
  • Clean fill / regulated fill evaluations
  • Industrial facility decommissioning planning and CQA
  • Litigation support
  • Wetlands and ecological studies
  • UST, AST and bulk storage facility closure investigations and reporting
  • RCRA and CERCLA investigations

At EARTHRES, we turn your vision into reality by utilizing our collective experience in the sciences and engineering. We will advise what additional investigation, mitigation or other remediation services are warranted for the successful development of your project.

Maintaining the integrity of our water supply is challenging to say the least.  A continual intricate balance of surface water, groundwater, climate change, droughts and in many times, strict regulations governing the conservation of this precious resource, can seem in direct competition with corporate initiatives.

EARTHRES hydrogeologists and geologists keep the water supply in mind when designing and this keeps water usage and wastewater to a minimum.  We make certain your manufacturing process will see favorable reductions in operating costs, while still keeping in compliance with federal regulations that protect our natural water resources.

We offer a full range of hydrogeologic and environmental services that can help meet your long-term goals while respecting the water supply.

Our geophysical services experts will help you get a comprehensive look at your site by using techniques especially suited for your site and project needs.  Our team of experts can help you get a first look at subsurface conditions before undertaking costly drilling or digging activities.  Geophysical surveys can be paired with existing site data to reduce costs and optimize project results.  Whether you’re looking for where to drill a new well or identify areas to avoid, or if you need to fully characterize subsurface conditions, EARTHRES will help you get the full picture for your project’s needs. If there are risks discovered, EARTHRES will be there to provide recommendations for remedial alternatives.

Invest in the EARTHRES team for your geophysical needs.

EARTHRES engineers and geoscientists routinely perform surveys to assess near-surface geologic and geotechnical site characteristics. Our team is trained in advanced non-invasive technologies like seismic surveys, electrical resistivity imaging, ground penetrating radar, magnetometer surveys, and 3D imaging techniques. These tools allow us to assess subsurface conditions at your project site and characterize key features like depth to bedrock, depth to water, pinnacled bedrock, sinkholes and other karst features, soil and groundwater contamination, buried waste, water-producing zones, mineral deposits, buried drums, or other anthropogenic artifacts beneath the surface.

From karst and geotechnical investigations to environmental remediation and water supply projects, EARTHRES can assist with your project’s investigation requirements, and help you see it through to completion.
