Mobile water treatment eliminates iron level issues
This client operates a groundwater treatment facility at a Super Fund site where groundwater is pumped to a VOC stripper for the removal of TCE which is then re-injected into the aquifer. High iron levels in the groundwater caused fouling of pumps, pipes and well casings. This fouling threatened the reliability of the process in terms of flow.

Municipal drinking water treatment
Municipalities are often faced with VOC contamination of their source wells. Chemicals like Vinyl Chloride and Trichloroethylene can leach into aquifers used as source water for municipal wells. When this occurs, in many cases the most cost-effective solution is to treat the water to remove the VOCs using air stripping, which has been established as a Best Available Control Technology BACT for this application.
