2012 Overall Integrated Reporting Water Quality Ratings


Download Link: ftp://ftp.nconemap.com/outgoing/vector/waterq_ratings.zip
Abstract: This data set contains overall water quality ratings for 13,176 waterbodies in North Carolina. The overall integrated reporting categories indicate if a water is Supporting or if one or more uses are Impaired. The data assessed were from over 5,000 monitoring stations with data and information mostly collected in calendar years 2006-2010.
Purpose: These data are mostly used to have a statewide perspective on the locations of impaired and supporting waters. More detailed information and the methods are available here http://portal.ncdenr.org/web/wq/ps/mtu/assessment
