WMA WATER WITHDRAWAL AND NPDES WASTEWATER DISCHARGE SUMMARY


Based on available information there are no WMA regulated withdrawals and NPDES dischargers in this subwatershed.

USE ASSESSMENT


Sampling of Cobb Brook (DO, temperature, pH, TSS, nitrate-nitrogen, total phosphorus, and bacteria) is conducted on a monthly basis by TRWA near General Cobb Street, Taunton (Station COB-013) and near West Water Street, Taunton (Station COB-000). The TRWA reported high phosphorus and fecal coliform levels at their sampling station near General Cobb Street, Taunton (COB-013) in May 2002. The TRWA found that high coliform counts occurred at this station and at Station COB-000 intermittently throughout 2002 (Domingos 2003a). Although a draft Quality Assurance Project Plan (QAPP) was reviewed in 2001, a final QAPP for the TRWA has not been approved and their data are not quality-assured. Therefore, the designated uses for Cobb Brook are not assessed.

RECOMMENDATIONS

Conduct monitoring (biological, habitat and water quality) to evaluate the status of the Aquatic Life Use in Cobb Brook bracketing potential sources of pollution (e.g., development).


Conduct bacteria sampling to evaluate effectiveness of nonpoint source pollution control activities and to assess the status of the Primary and Secondary Contact Recreational uses.
The TRWA should continue to conduct water quality monitoring at its established sampling site on Cobb Brook to meet its sampling objectives. In order for the MassDEP to utilize the TRWA data for water quality assessment reporting purposes, the TRWA should work with MassDEP to meet its Quality Assurance /Quality Control requirements.

Unnamed tributary (Segment MA62-48)

L



ocation: Channel from Taunton Municipal Lighting Plant, Taunton to confluence with Taunton River, Taunton.

Segment Size: 0.002 square miles

Classification: Class SA (Proposed SB)
Based on information from a 1963 U.S. Geological Survey map of the area, this channel was originally a wetland; i.e., no channel or stream was apparently present prior to the Taunton Municipal Lighting Plant (TMLP) facility being built. Thus, the channel was either dug or formed from the force of the discharge. The channel is now considered to be a “tidal creek”.
