.. ~.,/"' A Phase I i nvestigation of the abandoned disposal site at Singer
,; Furniture Plant No. 3 was conducted in October, 1982. Four monitoring
·;· wells were installed dur1ng this investigation to determine the f quality of groundwater underlying the disposal site area and to obtain
hydrogeologic information. Analysis of groundwater from Well N-1,
located immediately adjacent to the disposal site, revealed the
presence of three organic compounds. Several metals were also
detected at N-1 in concentrations above the primary drinking water
standards. Analysis of groundwater from the other three Phase I wells
did not detect priority pollutant organics or metals of significance.
A Phas~ II investigation was performed in August, 1983, to evaluate
the possibility that the compounds detected at N-1 have mi grated into
the alluvial floodplain of Lower Creek. Three additional monitoring
wells were installed during the Phase II investigation. These wells
were installed at greater distances from the disposal site to
determine 1f a contaminant plume exists and the rate and direction of
groundwater f1ow. Analysis of groundwater from these we11s did not
reveal that materia1 is migrating from the area of Well N-1.
Additional groundwater samples were taken from the well network on
June 20, 1984, and analyzed for priority pollutants. All wells were
sampled with the exception of the background Well {S-1). The results
of all groundwater analyses performed at the site are contained in
this report. In addition, recommendations are included for a
continuing analytical program.

likely the result of laboratory contamination. This conclusion is
more valid considering that this compound has not been detected more
than once at any we11 location indicating random laboratory erro.r.
Table 2 contains all analyses to date for metals and conventional
~arameters. Except for the inital analysis at Well N-1, no met~ls
have been detected in the well network at significant concentrations.
In the most recent sampling and analysis round (June 20, 1984},
... Chromium was detected in E-1 and NE-1 at a concentration of 30 ug/1.
\Chromium was also detected in W-2 in the second sampling round (August
8, 1983 ) at a concentration of 40 ug/1. The concentration of Chromium
was non-detectable at these three we1ls during the other sampling and analysis rounds.

D. CONCLUSIONS
1. A groundwater sample collected in October, 1982. indicated the
presence of three organic compounds and several meta1s a~ Well
N-1.
2. Well N-1 is located within 50 feet of the base of the disposal
Site.
3. A groundwater sample collected from Well N-1 in June , 1984, did
not contain the organics and metals detected 20 months earlier.
4. The analyses performed on groundwater from N-1 indicates that any
source of contamination in this area must be minor because it is
not consistently observed.
5. Wells W-2, N-2 , and NE-1 were positioned specifically to determine
if a plume of contamination has migrated from the area of N-1
toward Lower Creek.
6. No contamination of any significance has been indicated at Wells
W-2, N-2, and NE-1 in two separate sampling and analysis rounds.
7. The data indicates that the groundwater in the alluvial floodplain
of Lower Creek is not being affected by.leachate from the
abandoned disposal site. ·

E. RECOMMENDATION~
Recommendations for a continuing monitoring program are made below:
1. Perform semiannual analysis at Well N-1 for metal, volatile, base
neutral, and acid fractions of the priority pol l utants.
2. Perform semiannual analysis at Wells S-1, W-18, E-1, NE-1, W-2,
and N-2 for metal and volatile fractions of the priority
pollutants.
Modifications to the above analytical program shoulc1 be considered if
organics or metals are detected at Well N-1. Should contaminants be
detected at N-1, Well N-2 and possibly other wells may have to be
included for a more comprehensive analysis to monitor a potential
contaminant plume.
