RE: Bottled Water and Reverse Osmosis Treatment System Offer Letter for 6461 MARSH RD
Dear Owner/Resident/Tenant:
Since early September 2017, Chemours—in consultation and cooperation with the North Carolina Department of
Environmental Quality (NCDEQ)—has been conducting a residential well sampling program in the vicinity of the Fayetteville
Works facility. Chemours entered into a Consent Order with NCDEQ and Cape Fear River Watch, which was approved by the
Superior Court for Bladen County on February 25, 2019.
Per- and polyfluoroalkyl substance (PFAS) concentrations in the drinking water samples for 6461 MARSH RD are greater than
or equal to 10 ng/L (for one PFAS) or 70 ng/L (for combined PFAS). Per the Consent Order, Chemours will install up to three
reverse osmosis (RO) drinking water treatment systems in your residence to treat drinking water. Bottled drinking water was
delivered with this letter, and Chemours will set your residence up with home delivery of bottled water until RO treatment
systems are installed.
What You Need to Know
This residence qualifies for a bottled water delivery service and the installation of a RO treatment system based on lab
complete sampling results. We will send these results to you once we receive the report from the laboratory. Information
regarding the drinking water program and the RO treatment system are included with this letter.
RO drinking water treatment systems are installed under sinks to effectively remove PFAS from drinking water. Chemours will
pay to have up to 3 systems installed in this residence and will maintain the systems for a minimum of 20 years. You are not
required to have a system installed; you may decline this offer or have less than 3 systems installed.
Chemours will set up a bottled water delivery service for this residence and pay to have up to 15 gallons of water delivered
per week until the system is in operation. Supplemental water is available for pick up at the Fayetteville works facility.
Instructions for the supplemental water program are on the back of this letter.
What You Need to Do
Please call 910.678.1101 to have a treatment system installed in this residence. Leave a message with your name, phone
number, and the address on this letter and a team member will return your call as quickly as possible.
Our Commitment
We are sorry for any inconvenience this has caused. This letter was sent to your attorney if our records indicate an attorney is
representing you in this matter.
Sincerely,

Brian Long, Plant Manager
Chemours – Fayetteville Works

What to Check
The preliminary laboratory results for this residence are presented in the table below. Compare your
preliminary laboratory results to the criteria to determine if your residence is eligible for a filtration
system. Criteria include:
 GT140 which means greater than or equal to 140 ng/L for HFPO Dimer Acid/GenX (140 ng/L is the
same as 0.14 ug/L and 140 ppt)
 GT70 which means greater than or equal to 70 ng/L for combined PFAS (70 ng/L is the same as
0.07 ug/L and 70 ppt)
 GT10 which means greater than or equal to 10 ng/L for one PFAS (10 ng/L is 0.01 ug/L and 10 ppt)

If the laboratory results are greater than or equal to 70 ng/L for combined PFAS or greater than or equal
to 10 ng/L for one PFAS, then you are eligible for reverse osmosis (RO) filtration systems.

If the laboratory results are greater than or equal to 140 ng/L for HFPO Dimer Acid/GenX, then you are
eligible for a granular activated carbon (GAC) filtration system.

The table below provides preliminary laboratory results. Results are presented in nanograms per liter
(ng/L) and micrograms per liter (ug/L) because laboratories report results in different units. Chemours
will send the certified laboratory results report for this residence once received from the laboratory.

Drinking Water Program Overview

Consent Order
Since early September 2017, Chemours—in
consultation and cooperation with the North Carolina
Department of Environmental Quality (NCDEQ)—
has been conducting a residential well sampling
program in the vicinity of the Fayetteville Works
facility.
The Court approved the Consent Order between
Chemours, NCDEQ and the Cape Fear River Watch
on February 25, 2019. Per the Consent Order,
Chemours will reduce air emissions, provide
alternative drinking water to qualifying residents,
conduct additional investigations, and release
investigation results to the public.

Drinking Water Program
Chemours is sampling well
water to determine if per- and
polyfluoroalkyl substances (PFAS)
in the water are equal to or above
the levels agreed to in the
Consent Order. PFAS are man-made chemicals
used in many different critical industry applications.
HFPO-Dimer Acid (GenX) is a type of PFAS. If the
result from the water at your residence is greater
than or equal to any of the levels presented below,
Chemours will replace your drinking water with one
of the three replacement water options explained
to the right.

140 ng/L is the same as 0.14 ug/L and 140 ppt

Replacement Water Options
Chemours is offering three options to remove PFAS
from drinking water:
 Connecting the home to
public water supply (if
NCDEQ determines it is cost
feasible) for wells with GenX
results greater than or equal
to 140 ng/L (140 ng/L is the
same as 0.14 ug/L and 140
ppt)
 Installing and maintaining a granular activated
carbon (GAC) whole-house filtration system
outside the home or reverse osmosis systems
installed at drinking water sources for wells with
GenX results greater than or equal to 140 ng/L
 Installing and maintaining a reverse osmosis
drinking water treatment system on up to 3 taps
for wells with PFAS results greater than or equal
to 10 ng/L (individual) or 70 ng/L (combined)
Chemours will maintain the water filtration systems
for a minimum of 20 years. In addition, we will
provide bottled drinking water to you until your
permanent replacement option is in place. Although
no standards have been established for other PFAS,
Chemours has agreed to provide bottled water for
residences with these very low PFAS levels.

Reverse Osmosis Treatment System Overview

Consent Order
Chemours will pay to install and maintain up to 3
reverse osmosis systems in residences with per- and
polyfluoroalkyl substances (PFAS) results greater than
or equal to 10 ng/L (individual) or 70 ng/L (combined).
Reverse osmosis drinking water
treatment systems remove PFAS
from drinking water. These systems
are installed under kitchen and
bathroom sinks to treat the water
from those locations. Chemours will
maintain the systems for a minimum of 20 years.
Residences with GenX (a type of PFAS) results greater
than or equal to 140 ng/L may choose to have
Chemours install more than 3 reverse osmosis
systems rather than a whole house granular activated
carbon (GAC) system, per the Consent Order.
 10 ng/L is the same as 0.10 ug/L
and 10 ppt;
 70 ng/L is the same as 0.70 ug/L
and 70 ppt;
 140 ng/L is the same as 0.14 ug/L
and 140 ppt.

How the System Works
Reverse osmosis systems
effectively remove PFAS from
drinking water. The treatment
systems are installed under kitchen
and bathroom sinks. As the water passes through the
system a membrane removes PFAS from the water.
Each system will provide up to 50 gallons of filtered
water per day for use as drinking water.

Installation Process
An authorized technician from
Advanced Water Systems Group
(AWS) will install the reverse
osmosis drinking water treatment
system. For your safety, all
technicians will wear AWS-Kinetico badges and
uniforms and drive AWS-Kinetico vans. Installations
only takes a few hours. Please ensure all domestic
animals are secured during the installation process.
To have a system installed, call 910.678.1101. Leave
a message with your name, phone number, and street
address. After speaking to you and receiving your
permission, Chemours will send your information to
AWS and they will call you to schedule an in-home
visit and the installation.
System Maintenance
The systems’ filters and membrane will need to be
replaced occasionally. When your systems are
installed AWS will provide instructions on how to
determine when the system needs maintenance.
They will also provide you a phone number to call
when your filters need replaced.
