Water Quality Data from Select Spring and Stream Sites and Water and Sediment Quality Data from the Colorado River and Major Tributaries in Grand Canyon, Northern Arizona (ver. 2.0, April 2024)
This USGS Data Release represents water and sediment quality data collected in the Grand Canyon region of northern Arizona.
There are 4 separate datasets associated with this Data Release:
Water quality data from major Colorado River tributary monitoring sites in and near Grand Canyon from 2015 through 2022.
Sediment quality data from the Colorado River and major tributary monitoring sites in and near Grand Canyon from 2015 through 2022.
Water quality results from spring and stream sites in Grand Canyon that were sampled by U.S. National Park Service personnel in 2016 and 2017.
Time series water quality results from select spring sites in Grand Canyon that were sampled using a Minisipper autosampler.
Filtered water samples were analyzed using inductively coupled plasma - mass spectrometry (ICP-MS). Sediment samples were first decomposed using a mixture of hydrochloric, nitric, perchloric, and hydrofluoric acids at low temperature. The resulting solution was analyzed by ICP optical emission spectrometry (OES) and ICP-MS.”
