IMPAIRED SEGMENT (IR CATEGORY 5)


Introduction

This is the most recent water quality assessment information for this waterbody segment. The assessment is based on water quality data that meet the quality assurance requirements of DEC’s Division of Water. An outline of the process used to assess the quality of New York State waters is described in the DEC’s Consolidated Assessment and Listing Methodology (CALM). The CALM describes the assessment and listing process to improve the consistency of assessment and listing decisions.

WATERBODY INFORMATION

Assessment of Best Use

Background

New York State waterbodies are classified to reflect their best use(s) and the assessment of a waterbody is based on the ability of waters to support them. This section lists whether this waterbody segment supports its best use(s). View DEC’s CALM for more information about the terms used below.

Best Use Use Assessment Use Assessment Confirmation Pollutant(s) Integrated Reporting Category 303(d) Year
Fishing Impaired Confirmed Fecal Coliform; PCBs and Other Toxics IR55 1998; 2002
Secondary Contact Recreation Unassessed — No Data IR3 N/A for Assessment Category
Primary Contact Recreation Unassessed — No Data IR3 N/A for Assessment Category
Source of Water Supply N/A for Waterbody Class — — — —
Shellfishing Impaired Confirmed Fecal Coliform; PCBs and Other Toxics IR55 1998; 2002
EPA Appended Listing N/A for Waterbody Class — — — —

5 In addition to the contaminants for which there are specific Health Advisories for the consumption of fish, other contaminants have also been identified as contributing to the fish consumption impairment. These substances may include mercury, dioxins/furans, PAHs, pesticides and other heavy metals.

Water Quality Monitoring Data Used

Background

Water quality monitoring data are collected by DEC’s Division of Water and community partners. While data are evaluated to assess whether best use(s) are supported, they may not be reflected in the final assessment of best use(s) presented above. The process for conducting assessments of best use(s) is explained in DEC’s CALM.

This section lists the data sources for the pollutants listed in the Assessment of Best Use table.
