LNAPL Site Management Light Non-aqueous Phase Liquid (LNAPL) contaminated sites can be very challenging to assess, remediate, and ultimately close out due to both technical and regulatory issues. Therefore, it is essential to develop a strategic action plan early in the process to establish goals, specify a remedy, and chart a clear course to achieve…
Flint and Lead: The Water-Public Health Connection This On-Demand webinar discusses the current state of science related to the health risks posed by lead and the value of engaging the water systems sector. Reports of elevated blood lead levels in children in Flint, Michigan, placed a national spotlight on the role of drinking water in lead…
Addressing Lead Exposure in our Communities This On-Demand webinar provides information about lead exposure, focuses on community solutions to lead exposure, and provides tools for preventing lead exposure in the home. It is based in part on the Flint Water crisis and provides strategies to prevent a similar event from occurring by highlighting strategies such…
Disposal of Confined Dredged Material This course was developed to provide guidance on designing and managing dredged materials from the bottom of streams, rivers, lakes, and coastal waters. Confined disposal sites are engineered structures designed to provide required storage volume and to meet required effluent solid standards. The guidelines provided in this course can be…
DNAPL Transport and Fate in the Subsurface Dense non-aqueous phase liquids (DNAPLs) such as creosote, coal tar, chlorinated solvents and polychlorinated biphenyl oils represent a particular class of soil and groundwater contaminant that exist as a separate liquid phase in the presence of water. DNAPLs come to rest in the subsurface as disconnected blobs and…
