Water Quality Samples for North Carolina

Click to hide state-specific text

The daily maximum and minimum water level values for groundwater wells after September 30, 2023 are no longer being displayed on NWISWeb. However, these values can be determined using the instantaneous values that are available through the "Time-Series: Current/Historical Observations" option in the available data dropdown box for the station.


! Discrete water samples data are undergoing modernization with this page no longer being updated with the latest data starting March 11, 2024
with a full decommission expected 6 months later. Learn more about the upcoming change and where to find the new samples data in our blog.
To view additional data-quality attributes, output the results using these options: one result per row, expanded attributes.
Additional precautions are here.
