Chromium
Soil Sampling as of 5/2009
The information
presented here represents initial results
from a
screening
survey of surface soil from Hudson County, NJ. The
soils were analyzed for the presence of hexavalent chromium. Various
quality checks remain to be carried out, and additional results will
be reported. The objective of this project is to identify potential
areas of chromium contamination in Hudson County that have not been
located in past investigations. Approximately 250 surface soil samples
will be analyzed for hexavalent chromium. The results will be updated
at this web site periodically.
Sampling
locations 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. Requests
for sampling in this general area may be requested by contacting Robert
Hazen at (609) 292-8294.
Hexavalent
chromium was not detected in approximately 95% of the soils samples.
Only 10 of 225 Hudson County soil samples to date have shown detectable
hexavalent chromium. They range from 2 to 58 ppm. The analytical detection
limit was approximately 2-3 ppm. The method of analysis was USEPA 3060A
and 7196A.
