| Abstract | The report describes an intensive water quality study conducted in the Virgin River and Kanab Creek drainages in Southwestern Utah in March, 1976. Water, sediment, and benthic samples were collected at selected locations throughout a total stream reach of 174 km (108 mi). Study results indicated a gradual degradation of water quality downstream from Zion National Park. Violations of recommended criteria/standard levels were most common for the salinity parameters, but concentrations of arsenic, iron, manganese, and mercury also exceeded recommended levels. In addition, high concentrations of suspended solids impaired the quality of water throughout much of the study area. |
