On June 30, 2022, Chemours submitted to NCDEQ and Cape Fear River Watch the Cape Fear River PFAS
Mass Loading Assessment – First Quarter 2022 Report pursuant to Consent Order Addendum
Paragraph 1(b). The report describes sampling activities and mass loading results for the Cape Fear
River and PFAS loading pathways from the first quarter of 2022. This submission was also pursuant toquarterly reporting of mass loading sampling outlined in the Corrective Action Plan (Paragraph 16). In
the second quarter, Chemours conducted quarterly mass loading sampling required by Consent OrderAddendum Paragraph 1.
Consent Order Addendum Paragraph 2
During the second quarter of 2022, Chemours operated and maintained the four flow‐through cells,i.e., the interim remediation systems, at Seeps A‐D. On May 31, 2022, Chemours submitted the Interim

The CO Addendum requires extraction of groundwater from seven existing Black Creek Aquifer
monitoring wells (BCA‐01, BCA‐02, PW‐11, PW‐14, PW‐15R, PIW‐9D, and PIW‐10DR) as an interim
measure while the final remedy is being constructed. As part of the construction of the permanent

2,968 residences receiving bottled water services.

Section 24 Drinking Water Compliance Plan
As discussed above, the off‐site replacement drinking water program continues. The Drinking Water
Compliance Plan is currently under review and some of the protocols are being revised based on
discussions with NCDEQ. The following revised procedures are currently implemented based on
approval by NCDEQ: Point‐of‐Use (POU) Granular Activated Carbon (GAC) filtration systems for commercial
establishments that were eligible for RO systems, pursuant to NCDEQ’s approval letter dated
January 5, 2021.

 The pilot program is now expanding to include additional residences for public water
connections in the study area. Chemours has identified potential additional residences for public
water connections. Chemours is working with counties and water providers to facilitate thepublic water connections where feasibility has been determined. One residence was connected
to public water in February 2022. Nineteen additional homes were connected to public water
through June 30, 2022.
 Since the second quarter of 2020, the GAC OM&M sampling has been revised to include
quarterly sampling in between the lead and lag carbon vessel and one annual raw water sample.

Four Counties Sampling Program
On March 28, 2022, Chemours received a letter containing comments from NCDEQ on the “Framework
to Assess Table 3+ PFAS in New Hanover, Brunswick, Columbus, and Pender Counties” (the“Assessment Framework”), which was initially submitted to NCDEQ on February 1, 2022. Chemours
submitted a response to NCDEQ comments and a revised Assessment Framework to NCDEQ on May
12, 2022. Both documents were prepared by Chemours’s consultant Geosyntec Consultants of NC, PC.
Chemours maintained communications with Brunswick County, Pender County, and New HanoverCounty representatives regarding water infrastructure and public water customers. Chemours
reviewed records received from county representatives in response to December 2021 and January2022 public record requests. Data gathering from the counties was considered complete on May 28,2022, after which Chemours commenced the preparation of a work plan for submittal to NCDEQ byAugust 26, 2022. The work plan will describe a scope of work to sample groundwater and soil, asoutlined in the Assessment Framework.
Interim Sampling and Drinking Water Plan for Four Counties
On May 2, 2022, Chemours received a letter containing comments from NCDEQ on the Interim Plan.
Chemours submitted a response to NCDEQ comments and a revised Interim Plan to NCDEQ on June 1,2022. The first monthly report to NCDEQ summarizing the activities conducted as part of theimplementation of the Interim Plan was submitted on June 15, 2022.
Based on the revised Interim Plan dated June 1, 2022, Representative Sampling activities included
eligible private wells identified through community outreach via letters across the four counties,
proximity to Consent Order Attachment C criteria exceedances, and requests received via the call line
or web form. In addition to the existing call line, a web form was activated by Chemours for residents
to respond to community outreach letters and request sampling of their private wells.
As of June 30, 2022, 5905 addresses have been screened for sampling eligibility, and 1292 met theeligibility criteria. Of these 1292 eligible locations, 504 have been scheduled for sampling and 416 havebeen sampled. Of the 179 samples with analytical results, 148 showed no exceedances of Consent
Order Attachment C criteria. Bottled water has been provided to the 27 residences that qualified. The
four other results that showed exceedances were resamples of wells that were sampled by NCDEQ andthese locations are already connected to a public water source.
