of Chromium Soil Sampling (August
2006 - June 2011)
presented here represents results
survey of surface soil from
Hudson County, NJ. The soils
were analyzed for the presence
of hexavalent chromium. The
objective of this project is
to identify potential areas
of chromium contamination in
Hudson County that have not
been located in past investigations.
A total of 266 surface soil
samples were analyzed for hexavalent
have been selected due to their proximity to known chromium contamination
sites and input from DEP site remediation staff and the public. Priority
was given to proximity to the most highly contaminated sites. Most
samples were obtained roadside or in public parks.
chromium was detected in 19
of the 266 samples. They range
from 2 to 356 ppm with an average
of 31ppm. The analytical detection
limit was approximately 2-3
ppm. The method of analysis
was USEPA 3060A and 7196A.
on all samples with hexavalent
chromium concentrations greater
than 2 ppm were provided to
the Site Remediation Program
for appropriate action.
