Environmental Services
Due diligence and environmental assessments for property purchases, sales, development, and permitting.
Environmental Due Diligence
GeoTek's environmental staff run due diligence for the purchase, sale, lease, development, and upkeep of property. Assessments cover sites across much of the United States.
Phase I ESA
GeoTek conducts Phase I Environmental Site Assessments (ESAs) in general accordance with ASTM E1527. Clients and lenders can add scope beyond that standard. A Phase I ESA generally includes:

Phase II ESA
A Phase II ESA investigation involves the assessment of a potentially contaminated site, which may include the collection of soil, water (surface/groundwater), or air samples. The contaminant(s) of concern vary greatly, so the scope of work for a Phase II will vary on a case-by-case basis. GeoTek will perform an initial Phase II ESA to identify the presence or absence of contaminants, which may represent a potential impact to soil and/or groundwater. If necessary, a more detailed site assessment will be conducted to characterize the extent of impacted soil or groundwater.
Site Remediation
If soil and/or groundwater have been impacted on your property, requiring remedial activities, GeoTek can design and implement necessary site remediation programs to address these impacts. The design phase will include consultation with the local environmental regulatory agency and obtaining their consent and agreement for remediation activities.

National Environmental Policy Act
GeoTek can perform National Environmental Policy Act (NEPA) Assessments if required by Federal or State regulatory agencies, such as the EPA, Bureau of Land Management (BLM), Federal Communications Commission (FCC), Housing and Urban Development (HUD), and more. The NEPA assessment includes a 10-point study, including research and field investigation into:
- Wilderness Areas
- Wildlife Areas
- Threatened or Endangered Species
- Critical Habitats
- Historic Districts, Buildings, Sites, Structures, or Objects Records Review
- Native American Religious Sites
- Flood Plains Records Review
- Impact on Surface Features
- Zoning & Lighting
- Radio Frequency Radiation
Depending on the findings of the initial assessment, a more detailed Environmental Assessment (EA) may be necessary for any or all of the items investigated.
Hazardous Materials
Facilities that use or store any type of hazardous material must report that information to the local Department of Environmental Health as a Hazardous Materials Questionnaire. The client needs the approved questionnaire to get building permits. GeoTek can complete and submit it.
