Brownfield Investigation (BFI) Work Plan Format

This BFI Work Plan format is inclusive and contains all the sections that may be applicable. Therefore, the sections that are not applicable to a particular site should be indicated as such in the work plan, instead of omitting that section.

1.0 Site Background

Describe site location and current layout and reference the CSM_SS for more information and include CSM_SS in Appendix)

2.0 Purpose of Work Plan

Describe why is this work plan is being prepared.

3.0 Scope of the Investigation

Describe the objectives of the investigation, such as identification of sources of contaminations and the lateral and vertical extent of contamination in different media and fate and transport of the contaminants and receptors.

4.0 Sampling Strategy/Approach

Describe the rational and process for why and how the location and number of samples were determined and how the results will be used for each of the following sections. The sequence of sampling and the contingencies for collecting samples etc., will be discussed(This should have been documented in the CSM-SS and should be reference)

4.1 Soil

4.2 Groundwater

4.3 Sediment and Surface Water

4.4 Soil gas sampling

4.5 Other Survey

5.0 Sample Analytical Methods

5.1 Analytical Methods and analytes selection in different media

Provide a short description why the analytical methods and the analytes were chosen. Reference the sampling and analysis table in CSM_SS.

5.2 Data Quality Objectives (field measurement, fixed lab etc)

5.3 QA/QC samples and analyses

(Describe how many field blank, Trip blank, MS/MSD will be collected and what analyses will be performed)

5.4 Data Validation

6.0 Risk assessment and Remedy evaluation

Describe the risk assessment approach that will be taken and how the data will be collected.

Describe any data collection that will be needed to evaluate the remedy

7.0 BFI Report

Describe any deviation from the standard BFI Report Format for DNREC’s review.

8.0 Project Team and Schedule
