Appendix F. Impaired Waters

This appendix presents the 2002 Integrated List of Waters for the North Coastal Watersheds. Waters listed in Category 5 constitute the 303(d) List and, as such, are reviewed and approved by the EPA. The remaining four categories are submitted in fulfillment of the requirements under § 305(b), essentially replacing the old 305(b) Report format.

Integrated list categories 1-3 include those waters that are either unimpaired or unassessed with respect to their support of designated uses. Often insufficient data and information exist to assess all designated uses of any particular waterbody or segment. Furthermore, no Massachusetts waters are listed in Category 1 because a statewide health advisory pertaining to the consumption of fish precludes any waters from being in full support of the fish consumption use. Waters listed in Category 2 were found to support the uses for which they were assessed, but other uses were unassessed. Finally, Category 3 contains those waters for which insufficient or no information was available to assess any uses. Waters for which assessments were determined to be insufficient for 303(d) listing were also included in Category 3. Waters exhibiting impairment for one or more uses are placed in either Category 4 (impaired but not requiring TMDLs) or Category 5 (impaired and requiring one or more TMDLs) according to the EPA guidance. Category 4 is further divided into three sub-categories – 4A, 4B and 4C – depending upon the reason that TMDLs are not needed. Category 4A includes waters for which the required TMDL(s) have already been completed and approved by the EPA. However, since segments can only appear in one category, waters that have an approved TMDL for some pollutants but not others remain in Category 5 until TMDLs are approved for all of the pollutants. [12]

Following is a summary list of water categories with the number of NCW waterbodies in each category, then the detailed list of each category of impaired waters in NCW.

 

  • Category 1             “Waters attaining all designated uses”                                                   None in MA
  • Category 2             “Attaining some uses; other uses not assessed”                                  19 in NCW
  • Category 3             “No Uses Assessed”                                                                                  10 in NCW
  • Category 4A         “TMDL is Completed”                                                                                None in NCW
  • Category 4B          “Waters expected to attain all designated uses in the near future”    None in NCW
  • Category 4C          “Impairment not caused by a pollutant”                                                  6 in NCW
  • Category 5             “Waters requiring a TMDL”                                                                      47 in NCW

North Coastal 303d list 1996:

Essex River (Class SA/ORW)

Segment MA93-11: headwaters to mouth at Essex Bay. (0.90 square miles): Shellfishing Non-Support due to pathogens, low DO (4.8 mg/l) also below standards.

Annisquam River (SA)

Segment MA93-12: Source to mouth at Ipswich Bay. (1.90 square miles): Shellfishing and primary contact recreational uses impaired due to pathogens--(onsite septic systems confirmed as a source(s) in 1994.

Bass River (B/WWF)

Segment MA93-07: Headwaters to inlet Shoe Pond, Beverly. (2.4 river miles): Data dated (1987), pathogens (limited data, max 8000cfu/100ml) and low dissolved oxygen in upper end of segment (3.1 & 3.3 mg/l) impair primary contact and aquatic life use support.

Bass River (SB)

Segment MA93-08: Inlet Shoe Pond to confluence with Danvers River (0.10 square miles): 1987 data pathogens impair primary contact recreation, shellfishing area has been closed.

Danvers River (SB)

Segment MA93-09: From the confluence with Porter, Crane and Waters Rivers to mouth at Beverly Harbor (0.5 square miles): Data is old; fecal coliform levels impair primary contact recreational and shellfishing uses, CSOs are a problem. Elevated concentrations of heavy metals (Cr, Pb, Zn, Hg, As) and some PAHs in sediment also documented.

Porter River (SB)

Segment MA93-04: Confluence with Frost Fish Brook to confluence with Danvers River, Danvers. (0.10 square miles): Data is old; fecal coliform levels impair primary contact recreational and shellfishing is prohibited. Elevated metals (Cr, Pb, and As) and PAHs in sediment, no known source.

Crane Brook (B/WWF)

Segment MA93-02: Headwaters to Mill Pond, Danvers (2.30 river miles). Fecal coliform levels impair primary contact recreation, ammonia 1.1 & 1.2 mg/l impairs aquatic life use.

Crane River (SB)

Segment MA93-03: Outlet Mill Pond to confluence with the Danvers River, Danvers (0.08 square miles): Pathogens impair primary contact recreational use, shellfishing is prohibited. Metals and PAHs moderately high in sediment.

Waters River (SB)

Segment MA93-01: Headwaters to confluence with Danvers River (0.08 square miles): fecal coliform levels impair primary contact recreation use, shellfishing is prohibited. Metals and PAHs low in sediment.

North River (SB)

Segment MA93-06: Confluence with Goldthwaite and Proctor Brooks to confluence with Danvers River, Salem (0.20 square miles): pathogens impair primary and secondary contact recreation, shellfishing is prohibited, low dissolved oxygen and high concentrations of ammonia-nitrogen impair aquatic life use. Sediment has high concentrations of heavy metals (Cr, Pb, Zn, Cd, and As) and PAHs.

Goldthwaite Brook (B/WWF)

Segment MA93-05: Outlet Cedar Pond to confluence with the North River, Peabody (3.30 river miles): pathogens impair primary contact recreation, low dissolved oxygen, elevated TP and high ammonia-nitrogen concentrations impair aquatic life use. Eastman Gelatin instream toxicity testing data (required by NPDES permit # MA0003956) 1995/1996 data indicates acute instream toxicity due to storm water, slight effects due to dry weather discharges, and no adverse impacts to C. dubia at the upstream sampling station.

Forest River (SB)

Segment MA93-10: From mile point 0.5 to West Shore Drive, Salem (0.05 square miles): pathogens impair primary contact recreation, shellfishing prohibited, low dissolved oxygen (below 5.0 mg/l) impairs aquatic life use. Sediments found to contain high Pb and Cr and low/moderate concentrations of PAHs.

Saugus River (SB/ORW)

Segment MA93-14: Saugus Iron Works to the mouth at Lynn Harbor (0.80 square miles): pathogens impair primary and secondary contact recreation, shellfishing prohibited. Low dissolved oxygen (<4.0 mg/l) and ammonia-nitrogen (0.25 mg/l) impair aquatic life use. High levels of Zn in sediment. CSO Facilities Plan in development.

Pines River (SB/ORW)

Segment MA93-15: Route 1 Revere/Saugus to confluence with the Saugus River (0.7 square miles): Conditional restriction of shellfishing in several areas. Source differentiation study needed to identify specific sources of pathogens.

Essex Bay (SA)

Segment MA93-16: 1.15 square miles. Shellfishing conditionally approved, NERO has enforcement action for town of Essex regarding sewering issues related to bacterial loading.

Rockport Harbor (SB)

Segment MA93-17: 0.02 square miles. Pathogens impair shellfishing use--based on DMF status. Possible sources listed as on-site sewage disposal and marinas.

Gloucester Harbor (SB)

Segment MA93-18: 2.24 square miles. Pathogens impair primary contact recreation and shellfishing use. POTW discharge has been moved out of harbor. Gloucester consulting reports should be reviewed to determine need for additional work. CSO Facility Plan in development.

Manchester Harbor (SB)

Segment MA93-19: 0.29 square miles. Pathogens impair shellfishing use. NPDES discharge Manchester POTW.

Beverly Harbor (SB)

Segment MA93-20: 0.78 square miles. Pathogens impair primary contact, DMF does not list harbor for shellfish management area therefore not assessed as a use.

Salem Harbor (SB)

Segment MA93-21: 1.62 square miles. Pathogens impair shellfishing use. SESD effluent chronically toxic (see attached TOXTD summary). Initial TRE/TIE results indicate ammonia as primary toxicant (notes from 1992)--this information needs to be updated. SESD effluent scheduled to go on-line with secondary treatment in June 1996. Needs follow-up status/information.

Salem Sound (SB)

Segment MA93-25: 10.01 square miles. Pathogens impair primary recreational use and shellfishing use. Violations of dissolved oxygen standards measured but infrequent, ammonia-nitrogen exceeds 0.25 mg/l at SS01 & SS02 sampling stations. Source differentiation study recommended to identify source(s) of pathogen contamination.

Marblehead Harbor (SA)

Lynn Harbor (SB)

Segment MA93-23: 6.67 square miles. Pathogens impair primary contact recreation and shellfishing is prohibited.
