 Site Lo ca tion:

The Hemphill Road TCE site consists of a No rthwe st (NW) p arcel and a South ea st (S E) par ce l along Hemphill Roa d

n ea r the int er s ec tion of Forbes Road in South Gastonia, No r th C ar olina, a nd an a ss ociated ground water conta min ation

plume.

 Site Hi

st or y:

Du ring the 1950s, the si te owner re ported ly used the SE p arcel to re cyc le sev eral thousand ch emi ca l d rums. The owne r

re po rted ly dumped d rum re sidues onto the grou nd

, th en rinsed, burn ed and fla tt en ed the d rums for sa le as scrap metal.

The NW parcel was purch ased in 1973 and the SE p arcel in 1988 and was op erated as Gastonia In du st rial Tru ck.

 Site Contamination/Contaminants:

Trichloro e th ene (TCE)-conta min ated ground water was discov ered in 1988 in a p r iv a te d rinking water we ll n ea r the

site. Follow-up investigation in 1989 re v ea led TCE conta min ation in an adj ace nt residence to the no r th on Hemphi ll

Ro ad, as we ll as in the Gastonia Industrial Tru ck ’ s fac ili ty production we ll. In 1999 TCE was found in the n ear b y Kensington Estates co mmunity we ll. Sou rc e investigations on both the NW and SE p rop er ti es rev ea led only trac e

lev els of TCE in soils on the SE parcel, indi ca ting th at a si gnifi ca nt sou rc e of TCE may no longer remain in the soils.

 Potential Im

p ac ts on Surrounding Community/Environment:

Pr iv a te d rinking water we lls on Hemphill Ro ad and the Kensington Estates community d rinking water we lls ar e

conta min ated with TCE and ar e lo ca ted as fa r as 1⁄4 mi le to the we st of the SE p arcel on Hemphill Ro ad. Anoth e r

conta min ated community we ll, We sl ey Acre s, is lo ca ted be tw ee n 1⁄4 and 1⁄2 mile to the south. The und er lying geol og y

of the area is fr ac tu red b ed ro ck and conta min ation is likely migrating via bed ro ck fr ac tu re s.

 R es pon se Activities (t

o date):

Following the disco very of conta min ation, the Kensington Estates we ll was tak en o ff line and ho ok ed up to the Am y Acres community we ll. At the time of shutdown, the Kensington Estates we ll s er v ed 100 p eople. The own er s of the

two p r iv ate re siden ce s pl ace d f ilt er s on th e ir

wells, but the filt er s weren ’ t mainta in ed and one was d et er min ed to be not

wo rking in 2012. One additional we ll was found conta min ated. In May 2012, the EPA installed whole house filter

systems on the three private drinking water wells.
