Surface water samples (n = 33) were collected in fall of 2023 at stream sites in Scott County Iowa, USA and were analyzed for microbial source tracking markers by quantitative polymerase chain reaction at the Laboratory for Infectious Disease and the Environment (LIDE). Microbial source tracking markers identify fecal sources of contamination by detecting microbes that are specific to certain animals. Cooperators include Partners of Scott County Watersheds, Prairie Rivers of Iowa, and U.S. Department of Agriculture-Agricultural Research Service.

Concerns exist that the degradation of water quality in Salado Creek near Salado, Texas could adversely affect recreational uses and harm salamander populations that live in and near springs that discharge into the stream. Salado is part of the rapidly growing Killeen-Temple-Fort Hood area; land-use changes in the Salado Creek watershed could adversely affect water quality in Salado Creek. Streamflow in Salado Creek is generally derived from the Salado Springs complex during low-flow conditions (dry weather) and from the springs and surface runoff during high-flow conditions (wet weather). A better understanding of the types of waste (human, animal, or both) that may be entering the stream and springs is needed...
