Notice:Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake, Volcano, LANDSAT and Water information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown.

Constituents Measured or Computed Continuously in Wisconsin

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 Wisconsin. Click on a constituent for more detailed information, including a list of where it is measured or computed.

Constituent Name Units Criteria
Chloride, dissolved milligrams per liter (mg/L) 757 mg/L, 395 mg/L
Computed discharge cubic feet per second (cfs)
Dissolved oxygen milligrams per liter (mg/L)
Escherichia coli bacteria most probable number (MPN)
Fecal coliform bacteria colonies per 100 milliliters (col/100mL) 200 col/100mL
Specific conductance at 25 degrees Celsius microsiemens per centimeter (uS/cm)
Total phosphorus milligrams per liter as phosphorus (mg/L-P)
Total suspended solids milligrams per liter (mg/L)
Turbidity, measured as NTU or FNU formazin nephelometric units (FNU)
Water temperature degrees Celsius (°C)
