Kansas Real-Time Water Quality

Constituents Measured or Computed Continuously in Kansas

Continuous measurements of constituents (water-quality parameters) can be obtained by direct measurement using sensors, or by indirect computation using models.

Below is a list of constituents continuously measured or computed by the USGS in Kansas. Click on a constituent for more detailed information, including a list of where it is measured or computed.
