Real-Time Monitoring Of Water And DNAPL Levels Using Level TROLL® 500 Instruments

A dense non-aqueous phase liquid, or DNAPL, is a substance that is denser than water and only slightly soluble. Because of these properties, DNAPLs introduced into the environment generally sink below the water table and may migrate down through an aquifer. This can pose risks to the environment and human health and may necessitate remediation.

Site remediation is a complex process that often requires a custom approach, and depending upon site characteristics, different treatment techniques will be appropriate. During the various phases of remediation such as site characterization, clean-up, and long-term monitoring, it is important to evaluate the DNAPL layer in a water column.
