“Test results for drinking water in Plainfield Township being treated with its new granular activated carbon filters have not detected any PFOS and PFOA, according to township officials.

Staff at the water plant, located at 5220 Woodfield Court, installed the three new GAC filters in June and will install the final two when water demand begins to taper off as the weather cools down.

The new system, made possible with a $750,000 state grant, removes per- and polyfluoroalkyl substances, called FAS or PFCs, that were previously found at low levels in township water.

‘Because of the high demand for water in July and August, we could not afford the downtime to replace the final two filters,’ Rick Solle, director of Public Services, said. ‘We had to wait until customer demand goes down, which typically happens at the end of summer when folks stop watering their lawns.’

Installation is expected to begin the first week of October and should take approximately three weeks, according to Solle.

‘Once the final GAC filters are installed, we will have the capacity to filter nine million gallons a day through GAC, which is enough water to take care of regular demand,’ Solle said…

Previous tests from the first quarter of 2018 showed combined levels of PFOA and PFOS at 6.5 parts per trillion, said Donald Petrovich, superintendent at the water treatment plant. That is below the U.S. Environmental Protection Agency’s lifetime health advisory limit of 70 ppt.”
