Residents living in the neighborhood along Flamilton Avenue, North
Forsythe Street, Ross Court and Glendale Drive in Franklin may see work
crews collecting samples along streets over the next few months. The
U.S. Environmental Protection Agency is overseeing contractors collecting
samples as part of a contamination investigation (see Study Area map, last
page). This area is south of the former Franklin Power Products/Amphenol
Corp. site at 980 Hurricane Road in Franklin. Amphenol, under EPA
oversight, is completing a vapor intrusion investigation to determine if
volatile organic chemicals, or VOCS, including TCE and PCE, are impacting
homes. EPA thanks you for your cooperation and apologizes for any
inconvenience during this investigation.
Soil gas, sewer gas, and groundwater sampling
During September and October, workers sampled soil on city-owned right-
of-way (along streets) and in sewer manholes to collect soil gas and sewer
gas samples. The work was completed by AmphenoFs contractor, IWM,
consistent with requirements of the EPA Corrective Action program. Later
this month, crews will be sampling groundwater in the same area using
drilling equipment. Groundwater is an environmental term for underground
sources of fresh water.
The sampling is part of an investigation to see whether historic releases of
solvents into a stonn sewer and the ground at the former Amphenol site may

be impacting residents in nearby homes. Releases of
solvents at the site occurred prior to 1983. However,
soil and groundwater contamination may still be
present in the area, including near sewers. IWM has
been sampling indoor air in some homes near the
former facility to see if VOCs have penetrated inside
buildings. Follow-up activities may include sampling
beneath and inside more homes based on the soil, sewer
and groundwater sample results.
The VOCs that make up solvents can turn into gas and
move upward from soil and groundwater into homes
through openings such as cracks in foundations. VOC
gas may also move into homes when sanitary sewer
pipes have fissures or breaks and there is nearby-
contaminated soil or groundwater emitting VOC gas.
This problem is called vapor intrusion.
Background
In 1996, EPA evaluated vapor intrusion in the
neighborhood south of Amphenol. Based on the science
at the time, EPA determined that exposure to the levels
of VOCs present did not harm human health. EPA has
since established new vapor intrusion guidance and
updated health-based screening values for some VOCs,
and therefore must collect new data to compare against
these updated values.
Where VOCs are present above levels of concern,
home-specific mitigation techniques will be completed.
Potential actions may include installing vapor removal
systems under homes, lining sewers, sealing openings
at utility connections, sealing basement walls and
floors.
In September, Amphenol began sampling soil gas,
sewer gas, ambient air, and indoor air at eight priority
homes near the facility. Access to eight additional
homes has been requested. Based on the results of all
sampling, additional priority homes will be sampled.
Home sampling is contingent upon access agreements
with homeowners and residents. EPA encourages your
cooperation with these efforts.
