016-Assessing Environmental Contamination I
4 $90.00
Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.
Course Description:
This course is intended for engineers, geologist, scientists, and technicians who supervise and conduct environmental field investigations intended to detect, delineate, and remediate contaminated volumes of soil and groundwater. It will be useful to those who are new to such work, but those who are experienced in environmental science should also find the information useful, simply because of the ongoing technical advances in this field.
Dynamic sampling is an investigative strategy that offers the ability to screen contaminant levels in soil and groundwater semi-quantitatively, while still in the field. This strategy virtually eliminates surprises that can occur from the traditional delay in receiving laboratory results. If contaminants are discovered in an area thought to be free of problems, the work plan can be revised dynamically, at the moment.
The membrane interface probe (MIP) is a powerful high-resolution screening tool capable of providing both volatile organic contaminant and soil conductivity data in real time. The MIP provides a real-time vertical log of volatile organic contamination and conductivity with depth. An MIP, used as part of a dynamic sampling strategy, can result in contamination assessments and remediations with significant cost savings, increased time efficiency, and superior outcomes.
