      • Local Street Directories
      • Historic Topographic Maps
      • Property Tax Records
      • Building Permits
      • Zoning/Land Use Records
    • Regulatory Agency Listings
    • Geology and Hydrology Conditions
      • Reviewed by licensed Geologist and Hydrologist
    • Property and Area Reconnaissance
      • Conducted by experienced site investigators
    • Interviews of current, surrounding and former occupants/owners
    • Other Unique requirements as needed by our clients
      • Building Materials

  • Phase II Environmental Site Assessment

    Phase II Environmental Site Assessment

    A Phase II Environmental Site Assessment will be recommended if the results from the Phase I ESA or existing knowledge of chemical release indicate hazardous materials are likely found in the subsurface of the investigated property.

    Prior to undertaking any Phase II ESAs, Remediation Sciences meets with our clients to make sure we understand the specific needs that our client�s have for requiring a Phase II ESA. We design our solutions to make sure our client�s needs are met while providing detailed reports that will be upheld under the most detailed review.

    A typical Phase II ESA will include the collection of soil, soil gas, and/or groundwater samples from the property. A geophysical survey may also be conducted to verify the location of any unknown subsurface structures (such as underground storage tanks) that can be a source of hazardous materials. All of Remediation Sciences Phase II activities are overseen by a licensed professional, with all soil/water/soil gas analysis completed by a State Certified Laboratory.

    Remediation Sciences has extensive experience in site assessment, soil gas intrusion evaluation and innovative investigation methods. This extensive experience enables Remediation Sciences to give expert analysis and detailed reports that give our clients a clear picture of the precise hazards that are present on their property.

  • Remedial Feasibility Study and Remediation

    Remedial Feasibility Study and Remediation

    In most projects the soil and/or groundwater remediation method is selected, based on Remediation Sciences� extensive experience. However, for large projects, remediation feasibility studies are conducted following the United States Environmental Protection Agency (EPA) �Guidance for Conducting Remedial Investigations or a Feasibility Studies under CERCLA.� A remedial action plan is prepared based on the feasibility study and laboratory based or site based pilot testing.

    For Remediation projects, Remediation Sciences develops plans and specifications to meet our clients� specific needs. Our professionals manage construction activities and perform full program oversight. Remediation methods include in situ remediation (including bio remediation), soil vapor extraction, physical containment (including groundwater hydraulic control), and sub slab venting/depressurization. Remediation Sciences is also experienced in utilizing soil heating to remediate hydrocarbons from impacted soils.

  • Risk Assessment

    Risk Assessment

    Remediation Sciences provides risk assessment services to appropriately solve our clients� unique and specific challenges. For most sites, generic risk levels are used to solve the problems. In large and complicated projects, a full human health risk assessment (HHRA) is conducted by a toxicologist. A site specific conceptual model is prepared for the site showing all of the chemical release mechanisms, exposure pathways, and potential receptors. Our toxicologists use the most current models of the HHRA. If remediation is required, the site remedial action plans are prepared based on HHRA, streamlining the process and providing the most cost effective solution for our clients.
