Earth Science

The detection of organic contaminants such as Light Non-Aqueous Phase Liquids (LNAPL) and Dense Non-Aqueous Phase Liquids (DNAPL) in the sub-surface has been the subject of considerable interest among earth-scientists in recent years.

NAPL contamination may differentiate into at least four distinct forms, each of which has unique chemical and geophysical characteristics. There is a free product which is mobile or free to migrate under gravitational pull. Secondly, the residual phase is that portion which is left behind after the free product has migrated. Thirdly, volatile NAPLs may have developed a vapor phase plume in the space above the free product and the residual product. Finally, small amounts of hydrocarbon may enter the aquifer as a dissolved phase.

Our main product platform is the ECOPROBE, now in its fifth generation, delivers a new level of flexibility, convenience, and quality to in-situ detection and analysis of VOC`s and other contaminant indicators. Its cost-effective, definitive soil contaminant surveys provide an unprecedented breadth of high precision data results from the combined use of PID and IR detectors complemented by temperature, pressure and other custom data. A new dimension in the detection and monitoring of toxic spills, impoundment leakage and contaminant plumes is provided by the simultaneous measurement of total soil gas/vapor concentration together with four-channel selective analyses for methane, carbon dioxide, oxygen, and petroleum hydrocarbons.

RS DYNAMICS can also offer individual customized solutions for the ECOPROBE range based on your particular research needs. Please feel free to contact us at
