Hydrogeological Investigations

HRP provides a full range of Site Characterization, Aquifer Testing, and Bedrock Investigation services. We develop tailored investigation strategies to achieve technical and business-driven objectives. Our investigations:

• Maximize the use of existing data, wherever possible
• Rely on cost-effective screening level data, where appropriate
• Apply new technologies where cost savings, accelerated schedules, or other benefits can be achieved
• Make use of electronic data management and interpretive tools to improve project efficiency

Site Characterization
Some of the tools and technologies that HRP's environmental engineering consultants use to determine the extent and significance of environmental impacts include:

• Active and passive soil gas surveys
• Sensitive receptor surveys
• Low-flow groundwater sampling
• Passive Diffusion Bag sampling
• Geoprobe, hollow-stem auger drilling, sonic drilling and test pit sampling
• Micro-well, conventional monitor well, and nested well installations
• Geophysical surveys
• NAPL evaluations
• Geochemical evaluations and bioassay screening

Aquifer Testing
Our hydrogeologists perform a wide range of slug tests and pump tests in order to support:

• Development of groundwater containment strategies
• Water resource evaluations
• Groundwater modeling studies
• Design of de-watering systems
• Assessment of potential groundwater remediation technologies

We design these services to help you reduce or manage onsite liabilities, shorten remedial time frames, control offsite impacts, and/or develop existing water resources.

Bedrock Investigation
HRP's consulting engineers apply innovative technologies to address the challenges related to contaminant investigations in bedrock. Some of the technologies and services include:

• Rock coring, air rotary, mud rotary, sonic drilling
• Borehole Geophysics
• Fracture trace/Lineament analysis
• Bedrock outcrop studies
• Packer testing
• Tracer studies
• Matrix diffusion analysis
