Arizona Water Sentinels Data Page

Water Sentinels collect real data that is used to monitor changes to our rivers and to advocate for actions to protect them. The data collected is shared with the Arizona Department of Environmental Quality and other interested parties. Below are links to graphs depicting the data sets for the various constituents.

The Arizona Water Sentinels have been monitoring water quality and quantity on the upper and middle sections of the Verde River since 2006. To help monitor the health of the river, establish a baseline data set, and ascertain significant changes, we visit multiple sites along the river to collect water samples and to measure various constituents. See our “State of the Verde“ and “Going With the Flow“ reports for further analyses of this data.

Our San Pedro project began in February 2011. We visit five sites along the river to collect water samples to test E. coli levels, make field observations, and measure the pH, dissolved oxygen, and total dissolved solids concentrations in the river. E. coli is of concern as wastewater effluent is used to recharge the San Pedro River.
