NOTE: In North Carolina, the designated uses of all statewide water bodies are considered impaired for fish consumption due to a statewide fish consumption advisory that is in effect because of elevated mercury levels in fish tissue. Excluding the statewide mercury fish consumption advisory, the number of impaired waters is significantly less. To see an assessment summary that excludes the statewide mercury fish consumption advisory, see North Carolina's 2014 Integrated Report on the State Water Quality Data Assessment website: http://portal.ncdenr.org/web/wq/ps/mtu/assessment
