LAKE/RESERVOIR MANAGEMENT

Investigations

Our staff performs investigations to evaluate the health of the water column specifically with respect to:

Management

Lake and reservoir management is a specialty of American Geotechnical. Our hydrologist, hydrogeologist, and civil/geotechnical engineers are highly experience in the identification and mitigation of potentially hazardous lake perimeter, lake bottom, or circulation conditions unique to man-made water bodies.

 

Lake Condition Assessments

  • Continued water loss from ponds
  • Erosion at bridge footings/abutments
  • Seepage and erosion along utility trenches
  • Seepage of pond water into storm drains
  • Slope Erosion
  • Groundwater seepage
  • Structural movement
  • Sub-drain failure

WATER CONTROL STRUCTURES

Environmental Site Characterization Investigations

We perform detailed site characterization investigations for definition of on0site and off-site soil and groundwater contamination plumes.

Site Investigations Include:

  • Developing detailed work plans
  • Advancing soil borings/direct push borings
  • Installing soil vapor probes
  • Soil gas surveys
  • Installing ground water monitoring wells
  • Groundwater pump testing
  • Attenuation Monitoring services
  • Fate and transport assessments
  • Sensitive Receptor studies
  • Remedial Action Plans necessary to support site closure or site remediation services
  • Remediation System Design and Management
  • Post-Closure Monitoring

Environmental Projects Include:

  • Aquifer Characterization
  • Construction Documents and Permits
  • Groundwater Quality
  • Contaminant Migration Assessment
  • Fate and Transport Modeling
  • Remediation System Design
  • Well Head Protection
  • Litigation Support
 

Subsequent ground water characterization studies are performed when required to further determine soil and hydraulic characteristics of aquifer materials, definition of on-site and off-site soil, ground water contamination plumes, including remedial feasibility studies.

 
 

ENVIRONMENTAL MANAGEMENT

ENVIRONMENTAL MANAGEMENT SERVICES

Federal, state and local laws make current and prior property owners potentially liable for the entire cost of cleaning up a contaminated site. With new laws in effect in many municipalities, financial institutions, facilities managers and real estate managers are instituting procedures and guidelines to assess the status of a property with regard to environmental laws before a property ownership transaction. American Geotechnical offers a wide range of environmental management services, including those listed below.

PRELIMINARY (PHASE I) ENVIRONMENTAL SITE ASSESSMENTS

Phase I Site Assessments are performed in conformance with ASTM Standard Practice for Environmental Site Assessments: Phase I ESA Process (ASTM E1527) and Standard Guide for Environmental Site Assessments: Phase II ESA Process (ASTM E1903).

Regulatory agency documents are reviewed for historical and on-going operational practices, existence of leaking surface or underground storage tanks, visual indications of possible mishandling of toxic substances (e.g., spills or accidents, cleanup operations, etc.), previous testing by others, and punitive actions by various regulatory agencies.

Phase I Assessments

  • Existing site conditions
  • Current land use
  • Local/state/federal regulatory agency records for the site
  • Historic property reviews (aerial photographs, historic maps, etc.)
  • Surrounding property surveys
  • Personal tenant/owner interviews
  • Performing a site reconnaissance
  • Lien Assessment
