SECTION 1 • INTRODUCTION

1.01 Background

This data summary report presents results of the 1991 Thompson Island Pool

Total Suspended Solids Study (TIPTSSS) conducted by O'Brien & Gere Engineers,

Inc. This work was prompted by the PCB Reassessment Remedial Investigation and

Feasibility Study (RRI/FS) being performed on the upper Hudson River by the U.S.

Environmental Protection Agency (USEPA). The work being performed by USEPA

in conjunction with the Hudson River RRI/FS is described in their Phase 1 Report

(USEPA, 1991) and the Final Phase 2 Work Plan and Sampling Plan (USEPA,

1992). The TIPTSSS consisted of water column sampling and analysis for total

suspended solids (TSS). This study was performed in accordance with the Quality

Assurance Project Plan (QAPP; O'Brien & Gere, 1993) prepared for this project and

included the installation and operation of automatic samplers at selected locations

within the Thompson Island Pool.

1.02 Program Objectives

The objective of the TIPTSSS was to provide data to assist in the evaluation

of the origin and fate of suspended solids within the Thompson Island Pool. To meet

these objectives, TSS and hydrological data were collected from the upper Hudson

River under several hydraulic loading conditions. Elevated flow rates may induce

scouring of the river bed, leading to resuspension of sediments. The TIPTSSS was

therefore conducted during two potentially high flow periods. These periods included

April - May, and September - November, 1991.

SECTION 2 - METHODS

2.01 Sampling Locations

In order to evaluate the origin and fate of suspended solids within the

Thompson Island Pool, samples were collected from one upstream and one

downstream location in the Thompson Island Pool in April and May 1991. These

locations included the northern tip of Rogers Island in Ft. Edward (upstream end of

the Thompson Island Pool), and the western wing wall of the Thompson Island Dam

(downstream end of Thompson Island Pool). During September, October, and

November of 1991, samples were collected at three locations in the Thompson Island

Pool, including the northern tip of Rogers Island, the western wing wall of the

Thompson Island Dam, and a third location on the east shore of the river

approximately one mile upstream of the Thompson Island Dam (McDonald

property). This location was upstream of the Moses Kill, a major tributary to the

Thompson Island Pool, and downstream of Snook Kill. This location was sampled

in order to evaluate the contribution of Moses Kill on suspended solids in the

Thompson Island Pool. A sample collection schedule is presented on Table 1.

Sampling locations are illustrated on Figure 1.

2.02 Sample Collection Procedures

Samples were collected at each site with a battery operated Manning

automatic sampler. The samplers were secured at each location in locked, insulated

shelters. The sampler intake tubing was suspended at mid-depth (approximate due

to water level fluctuations) in the water column inside a protective PVC pipe casing.

O'Biien & Gere Engineers, Inc. 2 May 26, 1993

320662

Each sampler was programmed to collect a discrete sample every six hours. The

automatic samplers were serviced three times per week during April and May, and

twice per week during September, October, and November. The automatic sampler

operational sequence was as follows:

• initial set-up by O'Brien & Gere personnel (ampler programmed to

collect 1 sample every 6 hours for maximum of 6 days),

• sampling cycle begins (sampler purge cycle - compressed air forced

back through sampler intake tubing to remove residual water),

• sample collection cycle (sample drawn through intake tubing under

vacuum to central dispensing vessel),

• sampler purge cycle (compressed air forced back through sampler

intake tubing to remove residual water),

• sample dispensing (water flows by gravity from central dispensing

vessel to 1 of 24 internal containment vessels),

• cycle ends (internal dispensing arm advances to next internal contain-

ment vessel),

• sampler serviced by O'Brien & Gere personnel every 2-4 days, and

• samples transferred to containers for transport to laboratory (sampler

program re,aet).

Occasionally, the water level fell below the automatic sampler intake tubing. The

automatic samplers were unable to collect samples until the sampler intake tubing

was re-submerged. Sub-freezing conditions experienced in November, 1991 alsoX—-V

disrupted automatic sampler operation.


320663

When the automatic samplers were serviced, the samples were placed in

appropriate containers, chilled to 4°C, and transported to the analytical laboratory

for TSS analysis. Each sample was assigned a unique sample designation, identifying

sample location, date, and time. Chain of custody procedures and container

specifications presented in the QAPP (O'Brien & Gere, 1993) were followed. Field

logs are illustrated in Appendix B.

2.03 Quality Assurance/Quality Control Sample Collection

Quality assurance/quality control (QA/QC) samples were collected on a

routine basis during the TIPTSSS in accordance with the QAPP (O'Brien & Gere,

1993). These samples included the collection of equipment blank samples and blind

duplicate samples at a frequency of five percent (one blank and one blind duplicate

for every twenty samples). Equipment blank samples were prepared in the field by

rinsing an automatic sampler container with distilled water and collecting the rinsate

in a TSS sample container. Blind duplicate samples were prepared by dividing a

discrete aliquot into two samples. One of these samples was identified as described

in Section 2.02 and submitted to the laboratory. The blind duplicate sample was

submitted to the laboratory without indication to the laboratory of where or when

the sample was collected. The results of the QA/QC analyses are included in

Appendix A and are summarized as follows:

Less than detectable concentrations averaged as one-half detection limit.

Blind duplicate results presented as relative percent difference between paired

samples.

Blank sample concentrations ranged from less than detectable to 10 mg/L.

Variability between blind duplicate concentrations and paired sample concentrations

ranged from 0 to 170 relative percent difference, with the mean relative percent

difference at 61. These results are not unusual for total suspended solids analyses;

suspended solids are not typically evenly distributed throughout the water column.

Based on these results, it is concluded that the data generated in this study is

acceptable for qualitative and quantitative purposes.

SECTION 3 - DATA PRODUCTION AND REPORTING

3.01 OBG Laboratories. Inc.

OBG Laboratories, Inc. was responsible for performing TSS analysis on

approximately 1,319 water samples. These samples were analyzed for total

suspended solids in accordance with USEPA method 160.1 (USEPA, 1983). Upon

completion of the analyses, OBG Laboratories generated a series of data reports

entitled Laboratory Report, General Electric Company, Thompson Island Pool Total

Suspended Solids Program, Hudson River, N.Y. These data reports were prepared

consistent with New York State Department of Environmental Conservation

Analytical Services Protocol (NYSDEC ASP) Category B reporting requirements.

These data reports are presented as Appendix A, The organization of Appendix A

SECTION 4 - SAMPLING AND ANALYSIS RESULTS

4.01 Sampling and Analysis Results

The TIPTSSS involved the collection and analysis of water column samples

from three locations within the Thompson Island Pool region of the upper Hudson

River. The analysis of these samples provided data for TSS concentrations in the

water column of the upper Hudson River at specific locations. These data are

summarized on Table 2. Original laboratory data, including supporting documenta-

tion have been assembled into Appendix A according to the organization presented

in the Table of Contents of this report.
