How is MWC Addressing PFOA?

 In 2019, in anticipation that an MCL might be established, we

began evaluating and designing treatment options to mitigate PFOA

in groundwater.

 The Plant will use Granular Activated Carbon filtration, which has

proved effective against PFOA and PFOS and, once completed, will

support our compliance with the new standard.

 We are making an initial estimated investment of approximately

$47 million in upgrading treatment which is expected to be placed

into service by mid-2023.

 We have filed a lawsuit in the U.S. District Court for the District of

New Jersey against 3M Corporation to recoup wellfield remediation

costs.

 We are not the cause of PFOA but now have to remove what 3M

has put into our groundwater.
