Environmental Sampling Of Private Wells to Begin

North Platte, Nebraska

INTRODUCTION

The U.S. Environmental Protection
Agency (EPA) Region 7 will be in the
North Platte community sampling private
drinking wells the week of June 21,
2004. This sampling is part of a
removal assessment that will look for
volatile organic compounds (VOCs).

Prior to beginning the sampling
effort, EPA will send letters to
homeowners requesting access to their
property for sampling. EPA is working
closely with the state of Nebraska and
the City of North Platte to conduct this
effort.

SUPERFUND PROGRAM

Congress established the Superfund
program in 1980 in response to growing
concerns over human health and
environmental risks posed by hazardous
waste sites. Superfund locates,
investigates and cleans up hazardous
waste sites.

Officials from EPA's Superfund
Program and EPA contractors will be
performing the activities the week of
June 21.

SITE BACKGROUND

A Nebraska Department of Health
public water supply sampling program
(1988) initially detected volatile organic
compound (VOC) contamination in

some of the seventeen municipal wells that
serve the City of North Platte. Since then,
several VOCs have been identified in
ground water samples collected during
subsequent site investigations.

The VOCs present at the site include
tetrachloroethene (PCE), trichloroethene
(TCE), 1,1,2-trichloroethane (TCA),
styrene, and toluene. PCE is the only
VOC to have been detected above its EPA
Safe Drinking Water Act maximum
contaminant level.

In March 2002, EPA completed an
Expanded Site Inspection to provide more
conclusive information regarding the
source properties of ground water
contamination and to continue to evaluate
the threats to human health and the
environment associated with this site.

As part of this investigation, EPA
collected soil gas, soil, and ground water
samples from these 18 potential source
properties, and collected drinking water
samples from 14 of the 17 North Platte
municipal wells.

The investigation results confirmed the
detection of PCE in soil at one location,
and that the ground water had been
impacted by VOC contamination beneath
the site. However, the 14 municipal wells
that were sampled did not indicate any
VOC contamination in them above the
EPA Safe Drinking Water Act maximum
contaminant level.

CURRENT INVESTIGATIONS

EPA plans to focus the current
sampling efforts on private wells, as
opposed to the municipal wells that have
been sampled in the past. This
sampling is intended to find out whether
or not the contamination found in the
municipal wells previously has also
occurred in private wells.
