北卡罗莱那州的监管机构ordered the chemical company Chemours, spun off by DuPont in 2015, to take additional steps to prevent pollution from PFAS chemicals from entering the Cape Fear River—including construction of a 1.5-mile subsurface barrier wall and groundwater extraction system.
根据8月13日与北卡罗来纳州的环境质量和环保主义者达成的协议，生产Teflon和Freon等化学物质的公司必须在四个确定的“渗漏”中将毒素的水平降低99％，该水平超过一半以上污染的地下水到达河流。
In 2018, Chemours said it would spend more than $100 million at its Fayetteville, N.C., plant to control air and wastewater emissions from PFAS chemicals, known as per- and poly-fluoroalkyl substances, and also referred to as "forever chemicals" because they do not break down easily in the environment.
PFASs were discovered in 2017 in the Cape Fear River, the source of drinking water for Wilmington, N.C., and two counties. DuPont informed state officials of testing that indicated the chemicals had seeped into groundwater under the plant soon after production began in 2002.
Results of studies by seven state universities released last month showed high PFAS levels in the river, according to anAug. 3 reportin the Port City Daily newspaper.
该协议是2019年同意令的附录，该命令终止了该公司Fayetteville工厂的废水排放，并要求将空气排放量减少99.99％。
Chemours must have an interim measure to filter at least 80% of PFAS chemicals from the first seep completed by April 2021.
The permanent mitigation, the subsurface barrier and extraction system to get to 99% removal in groundwater, must be completed by March 2023. The company also must install filters in contaminated streams flowing into the river to remove at least 99% of PFAS pollution.
A capture-and-treat system must be installed to remove 99% of PFASs from onsite storm water that is adding residual pollution to the river.
该协议包含缺少建筑截止日期的处罚，包括150,000美元因未完成障碍墙，然后每周20,000美元，直到完成为止。
50万美元的罚款将是由于未能在初次示威中达到障碍墙的95％装载目标而导致的罚款，而未能罚款100,000美元，因为他们未能满足其余四个示威活动中的任何一个。
根据2019年的同意法令，Chemours制定了一项计划，以证明可以在两年内实现的工厂减少PFA的最大减少。
The new agreement will be filed with the Bladen Country Superior Court after a 30-day comment period.
北卡罗来纳州检察长乔什·斯坦（Josh Stein）于8月10日开始调查该州PFAS污染的程度和原因，包括受影响的水体和释放来源。
PFAS chemicals are used as additives in nonstick coatings and in fire suppression foams, among other things.
