Contaminated Groundwater: Analytical, QAQC, Detection Limits
By Richard Sloan, Chickadee Remediation Company
Groundwater has been contaminated at many locations due to spills and leaks of chemicals and other contaminants. Unfortunately metals, chlorinated solvents, gasoline components, pesticides, etc. are frequently detected in groundwater. In many cases it is necessary to define the nature and extent of the groundwater plumes and to take remedial response action to reduce the public health and environmental risks to acceptable levels.
The site assessment and remedial response process is driven by sampling and analysis of the affected media (typically air, soil, sediments, and water). From the initial "discovery" to the final site "closure" analytical controls the entire process.
This paper uses recent actual site examples to discuss the sampling analytical and QAQC issues involved in each step of the site assessment and remedial response process.
The process steps are:
