Cover Sheet & Data Summary

Completed Cover Sheet

Completed Data Summary For Technical Reports

Site Background & History

Site ID, ownership, operations and use.

Color copy of a map showing site location.

Description of current/historical, known/potential, contamination sources.

Description of all known discharges.

List and brief summary of all governmental records reviewed.

Historical map and aerial photo review summary.

Site Plan

A title, legend and true north arrow

Drawn to scale with a graphic scale bar

Source/creator of the plan

Location, elevation and datum of a permanent recoverable bench mark.

Surface topography using spot elevations, contours or noted changes in slope

Complete site property boundaries

Site Features

Public and environmental receptors

Site & Regional Hydrogeology

Description of stratigraphy, lithology, hydrology & contaminant flow

Geologic cross-sections

Potentiometric surface map w/ gw flow direction

Data Presentation

Groundwater and soil summary tables

Conceptual Model: Groundwater Contamination

Description of dissolved phase groundwater plume transport mechanisms, migration pathways and degradation pathways

Description of known or suspected sources of the contaminants detected in the groundwater (i.e., soil contamination, free product, waste storage areas, AST/UST systems, unreported discharges, etc.)

Groundwater contaminant concentration contours on the site plan and geologic cross-section(s) depicting lateral and vertical extent of representative contaminants exceeding standards.

Discussion of contaminants that are considered outliers or have no identified source. Provide data to substantiate off-site source claims.

Estimate of the mass of contaminated groundwater exceeding cleanup standards

Potential receptor map identifying and locating receptors within 1,000’ and list of water supply wells

Conceptual Model: Soil Contamination

Soil contaminant concentration contours on the site plan and geologic cross-section(s) depicting the lateral and vertical extent of representative contaminants exceeding cleanup standards

The estimated mass/volume of contaminated soil exceeding cleanup standards (not required if a source area is not present).

Conceptual Model: Indoor Vapor Intrusion

Identify, describe and explain potential pathways for indoor vapor intrusion, identify any exceedences, soil vapor monitoring or indoor air screening results (PID/FID meter readings), and provide recommendations for additional vapor intrusion study.

If pathway is complete and vapor intrusion is identified, provide indoor air monitoring results with comparison to standards and proposed abatement measures.

Remedial Alternatives & Recommendations

The Geotechnical Report must include either a, b, c or d and, if AGQS is exceeded, a GMZ depiction.

a. Closure recommended: Describe how site conditions meet closure requirements.

b. Recommendations for additional investigations and/or initial response actions: This shall include the steps necessary to finalize the groundwater management zone boundary and delineate source areas. Show all proposed explorations and sampling locations on a site plan.

c. Provide a preliminary screening of remedial alternatives: Including a description of the recommended remedial action and steps necessary to implement the recommended remedial action.

d. Interim response actions or presumptive remedy.

e. Preliminary GMZ boundary depiction.

Appendices

Colored photos of key features.

Description of field procedures for installing wells and sampling including sample preservation.

Field screening data.

Boring logs with PID results and monitoring well construction details.

Analytical data including chain of custody and holding times.

Detailed calculations.

Geotechnical Report Checklist Template

Created by: SafetyCulture Staff | Industry: General | Downloads: 7

Geotechnical checklists help ensure that all requirements and information needed for a site investigation report are completed. This site investigation checklist also helps improve the quality of geotechnical reports and avoid repeat site investigations. This geotechnical report checklist uses Done/In progress/Not Applicable response set and allows notes to be entered if needed. iAuditor templates can be edited to fit your site investigation report needs.

Signup for a free iAuditor account to download and edit this checklist. It will be added to your free account and you will be able to conduct inspections from your mobile device.
