Abstract
The Middle White River Watershed located in northeastern Arkansas is part of the larger White River drainage area that flows into the Mississippi River. The watershed has been on the 303(d) list for impairments such as pathogens, turbidity, total suspended solids, and dissolved oxygen. This study monitored water quality and potential toxicity in four subwatersheds of the Middle White River to inform management and regulation downstream conditions. During the three years of weekly sampling from 2019 to 2022, the subwatersheds violated state standards for pathogens, turbidity, and dissolved oxygen. Aquatic and sediment toxicity testing conducted on the four subwatersheds using EPA model organisms found adverse effects. This project provides data needed to help understand water quality and assess potential environmental risk in the Middle White River Watershed. Environmentally sound aquatic ecosystems are needed in order to protect resident organisms residing in these streams as well as in downstream ecosystems.
