GREENSBORO, N.C. -- — The City of Greensboro has updated its water treatment facility to better deal with a couple chemicals.
The City says it tested a new water treatment process to help deal with two chemicals that showed elevated levels a few months ago. Those are PFOS, and PFOA.
The new system is essentially a failsafe in case those chemical levels ever rise again.
The chemicals are constantly monitored, and if they ever go above the recommended standards again, a new powder-based system will be deployed for 5 days.
After five days, they levels will be checked again, and the city says the levels should return to normal.
