Monitoring of Contaminants and Consideration of Risk

Abstract

Groundwater monitoring is a critical component of activities performed at a site where the groundwater may have been adversely impacted by chemicals (i.e. contaminated). The specific purposes of groundwater monitoring will vary depending on the stage of impact identification. The elements of monitoring include:

• • initial site characterization using available information;

• • refining the site characterization through the installation of boreholes and wells, and sample collection and analysis;

• • designing a corrective action; and

• • implementing and monitonng a corrective action.
