Download or read book A Comparison of Suspended Sediment and E coli in Two East Tennessee Streams written by and published by . This book was released on 2009 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two frequent water quality problems for streams on state 303(d) lists are sedimentation and bacteria. Escherichia coli (E.coli) is monitored as a widely distributed, easily cultured species that can indicate pathogenic bacterial contamination in waters designated for recreational uses. Suspended solids are also an indicator of stream health because they stress aquatic ecosystems. I investigated the relationships between concentrations and loads of suspended solids and E. coli over different flows in two tributary streams of the Little River (HUC 06010201) in east Tennessee. One stream, Nails Creek, flows through a rural, agricultural area, while the second, Pistol Creek, drains a dominantly urban and residential watershed. I hypothesized that relationships between E. coli and suspended solid concentrations would differ between the two streams. From August 2007 through February 2008, I collected 20 water samples and suspended solids from each stream to be analyzed to determine bacterial and suspended sediment concentrations and loads, over a range of flows. I processed the samples for E. coli, total suspended solids (TSS), and loss-on-ignition, and used DNA analyses of Bacteroides to determine the percentage of bovine or human bacteria per sample. To determine relationships between the variables, I used non-parametric correlation analyses for in-stream relationships and Mann-Whitney-U tests for relationships between streams. No relationship was found between concentrations or loads of suspended solids and E.coli in either Nails Creek, or Pistol Creek. However, Nails Creek had significantly higher median concentrations of E.coli and TSS than Pistol Creek. Patterns of discharge, suspended solids, and E.coli concentrations and loads differed between the two streams, with Nails Creek samples having higher loads of TSS and E. coli. Pistol Creek had significantly higher TSS loads and E.coli loads at higher discharges than at lower discharges while there was no significant difference with discharge in Nails Creek. Nails Creek samples contained more bovine-associated fecal bacteria than human-associated fecal bacteria; Pistol Creek contained very little fecal bacteria. This study takes a step toward understanding relationships among suspended solids, bacteria, and discharge in Little River tributaries and provides a foundation for future investigations and water quality remediation efforts in the watershed.

Download or read book Armored Stanchion Cattle Water Access Effects on E Coli Suspended Sediment and Nutrient Loading to Spring Creeks written by William Adam Sigler and published by . This book was released on 2008 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Livestock grazing activities contribute to impairment of 5,200 miles of Montana streams. Implementation of most water quality improvement efforts addressing this issue is voluntary. Thus, it is important to present land owners with simple, cost effective approaches to mitigate water quality impairment. An armored stanchion (AS) water access was designed, implemented, and tested on Thompson and Story Creeks near Belgrade, MT. Riparian fencing was constructed to allow access at a water gap where the AS was constructed. The AS allows animals to access spring creek water to drink but does not allow them to enter the stream. An AS was constructed adjacent to a traditional (TRAD) water access on each stream for comparison. Water quality impairment was quantified downstream of each access with and without animals actively using the accesses. Instantaneous loads of E. coli, suspended sediment concentration (SSC), total Kjeldahl nitrogen (TKN), nitrate (NO3), total phosphorus (TP), and orthophosphate (PO4) were evaluated using Kruskal Wallis procedures. Contaminant loading from the AS access was not significantly greater than loading from the control with or without animals present. The Story Site did not consistently produce significant differences for the TRAD access with animals present versus absent under the different analysis approaches employed. Results at the Thompson Site produced significant differences for E. coli, TKN, and TP for the TRAD access when animals were present versus absent from the access. Estimates were made of percentage of time cattle occupied the Thompson TRAD access. These estimates facilitated calculation of daily loads attributed to animals actively using the access. For E. coli the load was 6.0 E9 CFU per day, 425.9 g per day for TKN, and 53.1 g per day for TP. These results indicate the AS access can reduce water quality impacts from cattle, compared to traditional access methods.

Book excerpt: Periphyton: Functions and Application in Environmental Remediation presents a systematic overview of a wide variety of periphyton functions and applications in environmental remediation, providing readers with an understanding of the biological/ecological features of periphyton, the methodology of their study, and their application in environmental conservation. With increases in environmental stress, anthropogenic impacts, and the global decline in biodiversity, there is a pressing need for methods to assess and improve environmental quality that are rapid, reliable, and cost-effective. Periphyton is an important component of benthic communities and plays a crucial role in the functioning of microbial food webs. Because of a number of advantages, such as a short lifecycle, relative immobility, more rapid responses to environmental stress and anthropogenic impact than any metazoa, ease of sampling, availability of taxonomic/molecular identification, and standardized methodologies for temporal/spatial comparisons, there has, in recent decades, been an increased interest in periphyton as a tool in biological conservation in aquatic ecosystems. - Presents case studies that help readers implement similar ecological designs - Focuses on the function of periphyton in remediating destructed ecosystems - Provides readers with an understanding of periphyton in practice, especially the value of periphyton in enhancing environmental and ecosystem qualities - Discusses the role of periphyton in purifying water and its effect on abiotic elements
