State IDWaterbody NameCategory 4a Designated Use-PollutantCategory 4b Designated Use-PollutantCategory 4c Designated Use-ImpairmentCategory 5 Designated Use-Pollutant
Waterbody LabelDover, NH Category 4a: TMDL is completed
Category 4c: TMDL not required since impairment is notcaused by a pollutantCategory 5: Impaired or threatened for one or more designateduses and requiring a TMDL (303(d) listed waterbody)
Category 4b: TMDL not required because other pollution control requirements are reasonably expected to result in WQS attainment
Swamp/Marsh
Designated Use AbbreviationsAL = Aquatic LifeFC = Fish ConsumptionPCR = Primary Contact RecreationSCR = Secondary Contact RecreationSh = Shellfishing
Notes:1) Only known impairments shown; waters may also be threatened or impaired by other pollutants or nonpollutants.2) All fresh surface waters in New Hampshire are impaired for fish/shellfish consumption by atmospheric deposition of mercury. See Approved Northeast Regional Mercury TMDL (December 2007); http://des.nh.gov/organization/divisions/water/wmb/tmdl/documents/northeast_final_tmdl.pdf
