Development of a fecal contamination monitoring and control strategy in Upper Fountain Creek, Colorado

The study tests a strategy for gaining information about fecal- contamination sources to Fountain Creek, a stream on the Colorado Front Range. This project will be done as a partnership between the USGS and Colorado Springs-area cooperators/stakeholders. The strategy includes initial screening of E. coli distributions, followed by intensive sampling for E. coli, nutrients, and microbial source tracking (MST) markers (Bacteroidales-based markers for human and ruminant fecal contamination, the Enterococcus faecium-carried esp marker of human fecal contamination, and organic compounds associated with human waste streams). The strategy will include steps to define and identify (in time and space) major contributions of fecal contamination and to test for specific fecal contamination sources in key samples. ?    Fecal contamination will be defined in time and space by longitudinal surveys of Fountain Creek during three conditions when E. coli concentrations are expected (based on prior data) to exceed standards (snowmelt, summer wet-weather flow, and summer dry-weather flow). ?    Five sample sites in critical areas, selected with stakeholder input based (in part) on longitudinal data, will be sampled every 2 to 4 weeks over one year to further evaluate spatial and temporal variation in fecal contamination. In addition to the predominantly dry-weather-flow periodic samples, additional samples will be collected during runoff events resulting from snowmelt and rainfall to further evaluate the relation of fecal contamination with hydrology. ?    Selected samples will be evaluated for wastewater analytes as a means of detecting human wastewater contributions, and MST markers as evidence of human or ruminant fecal contamination. Sample selection will be done with stakeholder input based on preliminary E. coli concentration, nutrient concentration, and field- parameter results.
