Developing the Scope of Work

The scope of work is developed based on information already known about the site.  This information typically comes from a Phase I Environmental Site Assessment and/or past investigations.  Sample locations, depth, QA/QC, and laboratory analyses are determined. 

There are seven main tasks in developing the Scope of Work:

1.       Review of Past Information

To determine where contamination is likely and also to determine the following:

2.       Site Limitations

Such as site access, depth to bedrock, presence of utilities, and any other impediments that may prevent the work from being completed. 

3.       Contaminant Distributions Analysis

The distribution of potential contaminants, properties, behaviors, and fate and transport characteristics of the contaminants are assessed. 

4.       Sampling

The sampling program should be in compliance with the regulating agency and provide information regarding where contamination is likely and   in what media (soil, groundwater, or air). 

5.       Health & Safety

The health & safety work plan should be in accordance with the applicable federal, state, and/or local requirements.

6.       Chemical Testing

Laboratory methods used should be capable of detecting the contaminants in question at concentrations equal or less to regulatory limits. 

7.       Quality Assurance / Quality Control Procedures

These procedures should be followed in order to assess the quality of the data collected.  Examples include trip blanks, calibration records, duplicate samples, and others.
