How do you remove TCE from drinking water?

Treatment options are available to remove trichloroethylene from well water. The most commonly used option is granular activated carbon filtration. 1 Options include central treatment (at the well or at entry to home) or a point-of-use device (kitchen sink filter).

Do water filters remove TCE?

A properly designed water filtration system will remove TCE. However, not all water filters remove this solvent. WECO water filters use the Best Available Technology (BAT) to remove TCE from your water supply.

How do you clean up trichloroethylene?

TCE usually is remediated through pump and treat, using either air stripping or granular activated carbon, but there are many innovative cleanup methods—physical, chemical, thermal, and biological—that have been applied successfully to remove TCE from soil and ground water or to convert it into nonhazardous compounds.Mar 7, 2022

What can I use instead of trichloroethylene?

The principal alternatives to TCE in hot vapour degreasing are methylene chloride (MEC) and perchloroethylene (PERC), with PERC being considered a ‘drop-in’ alternative to TCE in many cleaning applications by equipment manufacturers consulted for this review.

Is trichloroethylene banned in US?

In June 2018, EPA abandoned the proposed bans altogether and decided to fold those high-risk uses into a new risk evaluation of TCE—a move that is delaying action for years with no assurance those dangerous uses will be banned in the end.
