2.1.1 Narrative
This purpose of this
assessment project is to continue to evaluate metals concentrations in the
sediment along a portion of the West Fork River, which is situated downgradient
from a slag pile believed to have been generated by the long defunct Clarksburg
Zinc Company. This assessment will
determine if, and if so to what extent, this source is negatively impacting the
West Fork River sediment downstream of the slag pile. The project previously included
an evaluation of the background sediment from areas upstream of the assessment
area.
2.1.2 Response Actions to Date
On 08/20/2012 at 1120 hours,
START mobilized to the assessment site upon EPA direction. START first stopped in Pittsburgh, PA, to
acquire a rental Jon boat, trolling motor, and six inch Ponar Dredge. START then headed to the site location
Clarksburg, WV, arriving at approximately 1600 hours. START used the remainder of the afternoon to
scope out potential boat launching locations.
START found a couple areas for boat launching and mooring, including a
private residence located near the downstream boundary. START requested permission for private party
access, and the owners granted permission.
The OSC also mobilized to the site on this day.
On 08/21/2012 at 0800 hours,
START met with the OSC and prepared to begin sampling operations. Following a brief health and safety
discussion, the OSC and START traveled to the boat launch area to launch the
sampling team. At 0950 hours, the boat
was launched, and the sampling team was heading downstream to collect
samples. At 1015, START began collecting
samples at locations adjacent to the slag pile area. START performed written and photographic
documentation of all sample locations.
At 1030 hours, USFWS expert Kathy Patnode arrived on-site at the current
sampling locations near the slag pile.
Kathy indicated that there were not many significant sediment deposits
that she observed. She also indicated
that water quality appeared impaired, but the river has nice potential as it
appears to be a good riparian corridor.
START inquired about the potential need for pore water sampling. Ms. Patnode indicated that she would use a
water quality meter to survey potential locations along the slag pile area of
the river to assess for the need to collect pore water samples. At 1100 hours, START resumed collecting
sediment samples. At 1400 hours,
following a brief lunch, START headed to the furthest downstream location,
about a river mile downstream of the slag pile, in order to minimize sediment
disturbance by collecting samples in an upstream direction. At 1430 hours, START again met with USFWS
expert Kathy Patnode to over the results of her water quality testing for
potential pore water sampling locations. Kathy provided results. Ms. Patnode recommended we collect pore water
samples at five locations, and provided a sketch of the recommended sample
locations. At 1805 hours, START had
completed sampling operations for the day, and returned to the hotel in
Bridgeport, WV. The boat was left moored
at the private residence located near the downstream border of the assessment
area. Throughout this day, START
attempted to use the Ponar Dredge with little success due to rock and/or sand
encountered along the mid-channel area of the river. A GPS location was logged using an EPA
Trimble unit for all samples collected on this day. A total of 11 samples were
collected on this day, including one duplicate sample.
On 8/22/12 at 0800 hours,
START met with the OSC and prepared to begin sampling operations. Following a brief health and safety meeting,
START and the OSC returned to the boat mooring location to begin collecting samples. The OSC arrived with Larry Siranek, representative for WVDEP. Once sampling was underway, the START project
manager, the OSC, and WVDEP Larry Siranek set up a base camp in order to log sampling information into
the Scribe documentation program. Scribe
was also used to produce sample tags and labels on this day. At approximately 1430 hours, Larry Siranek departed the site. At 1730 hours, START had completed sampling
operations for the day, and at 1745 hours returned to the hotel in Bridgeport,
WV. The boat was left moored at the
private residence located near the downstream border of the assessment
area. START conducted written and
photographic documentation of all sample locations. A GPS location was logged using an EPA Trimble
unit for all samples collected on this day.
A total of 15 samples were collected on this day, including two
duplicate samples.
On 8/23/12 at 0800 hours,
START met at the residence where the boat was moored, and prepared to begin
sampling operations. A rinsate blank was
collected as one sample was collected on the previous day using the Ponar
Dredge. Sampling was delayed on this day
due to trolling motor battery issues.
START worked to remedy the battery issues. At 1030 hours, the battery issues were
remedied and the sampling team was departing the downstream residence to resume
sampling where efforts ended the previous day.
At 1045 hours, the START project manager and OSC set up a base camp in
order to log sampling information into the Scribe documentation program. The START project manager kept in contact
with the sampling team in order to obtain sampler and sample time information
for Scribe program data entry. At 1800
hours, START had completed sampling operations for the day, and at 1900 hours
returned to the hotel in Bridgeport, WV.
The boat was left moored at the private residence located near the
downstream border of the assessment area.
START conducted written and photographic documentation of all sample
locations. A GPS location was logged
using an EPA Trimble unit for all samples collected on this day. A total of 25 samples were collected on this
day, including three duplicate samples and one rinsate sample.
On 8/24/12 at 0800 hours,
the OSC and START met at the START hotel in Bridgeport, WV. START began organizing equipment in
preparation to collect a final rinsate sample, perform final decon on the Ponar
Dredge, and make room to pull the Jon boat out of the water. At 1000 hours, START and the OSC met at the
Clarksburg wastewater treatment facility flapper valve outfall as this location
was thought to be the easiest extraction point for the Jon boat. While pulling the boat out of the water, a
wastewater treatment facility representative inquired as to the
boating/sampling activities. The OSC
spoke with the representative and provided a brief explanation of the
assessment. Following Jon boat
extraction, The OSC and START returned to the staging area along North 25th
Street. START collected another rinsate
sample, and began preparing samples for final labeling and packaging. At 1100 hours, the OSC demobilized from the
site. At 1430 hours, all samples were
labeled, bagged, tagged, and packaged for shipment to the CLP laboratory. At 1500 hours, START demobilized from the
site. At 1630 hours, four coolers
containing all samples collected were dropped off at the Federal Express
location in Wheeling, WV for priority overnight shipment to the CLP
laboratory. At 1645 hours, START arrived
back at the Wheeling, WV START office.
