Integrated Report 2022 (references)
The NC Department of Environmental Quality’s Integrated Water Quality Report checks to see if North Carolina’s waterways meet federal and state standards every two years. It incorporates information from multiple data sources, such as local monitoring programs and voluntary work, to group bodies of water into five categories:
Category 1: Waters meet all standards.
Category 2: Waters meet some standards.
Category 3: Waters lacking enough data.
Category 4: Impaired waters with a plan.
Category 5: Impaired water and need a plan.
The data varies in quality and coverage, and not all water bodies are monitored equally, leading to some limitations in assessing smaller or remote areas.

NC DEQ AFO ANIMAL FEEDING OPERATION:
The AFO (Animal Feeding Operations) program at NC DEQ manages permit applications for big farm operations, such as those raising hogs, chickens and cows. These farms have to comply with regulations on the disposal of waste for water quality reasons. The permits are reviewed every five years to make sure that they’re up to date. Program data are collected through inspections and reports, but they don’t always provide an accurate picture of the environmental impact, and tracking varies by farm. Its limitations are inconsistencies of data and incomplete monitoring of waste management at every site.

NC Surface Water Supply Watersheds
In NC DEQ’s Surface Water Supply Watersheds maps, waterbodies are assigned to uses such as drinking water, swimming or fishing. These categories set the boundaries for water quality management to safeguard public health and ecosystems. They are based on water monitoring systems and scientific research, but the uncertainties are fluctuating water quality and monitoring performance. These classifications might have to be updated as water use varies.
NPDES Wastewater Discharge Permits
NPDES Wastewater Discharge Permits regulate treatment facilities’ discharge of treated wastewater into rivers and lakes to protect water quality. The permits cap the concentration of contaminants according to the water in place. They are the result of daily monitoring and assessments, though sometimes facilities can vary how these are tracked and reported which can impact the consistency of enforcement.

DWR FISH TISSUE MONITORING DATA
The DWR Fish Tissue Monitoring Program inspects North Carolina waterways for heavy metals, pesticides and PCBs (Polychlorinated Biphenyls). PCBs are industrial chemicals that build up in fish, and they are harmful if consumed. It’s data that are used to issue fish-consumption advisories to help keep people safe. They collect samples by electrofishing (which consists of fish that humans eat). Constraints: data are not collected in every watershed, and older data don’t necessarily reflect recent pollution.
