Tri-Cities Airport Using Worms to Solve a Huge Pollution Problem

The Tri-Cities Airport (PSC) has teamed up with BioFiltro to try a new theory to study the effectiveness of worm-powered wastewater treatment on airport de-icing wastewater. During the winter months, de-icing is heavily used and very important for aircraft safety. The de-icing fluids are made of ethylene glycol, propylene glycol, and a few other ingredients known to be potentially dangerous for the environment. In the past, the airport has collected the de-icing wastewater and then transported it to the Pasco Wastewater Treatment Facility to clean it of potentially dangerous elements. Now the treatment facility is having trouble keeping up with the amount of de-icer produced and asked the airport to try and find a different solution to take care of the de-icing wastewater.
