      Fecal coliform concentrations are routinely monitored in waterbodies as indicators of other more potentially dangerous human fecal-borne pathogens. However, high concentrations do not necessarily indicate human waste ...
    • Factors Influencing the Quality of Urban Streams in Georgia and the Implications for Stream Management 

      Mikalsen, Ted (Georgia Institute of TechnologyInstitute of Natural Resources, 1989-05)
      A statewide assessment of nonpoint sources of water pollution (EPD, 1985a) revealed that the beneficial use of urban streams not influenced by wastewater discharges had been severely impaired in four of five cases and ...
    • G.P.S. Applications in Support of the Georgia Environmental Protection Division's Drinking Water Program

    • The Importance of Specific Conductivity for Assessing Environmentally Impacted Streams 

      Wenner, David B.; Ruhlman, Melanie B. (Georgia Institute of TechnologyInstitute of Ecology, 2003-04)
      From over two years of quarterly monitoring in the Upper Oconee Watershed, three streams consistently had good to excellent water quality based on their biological index scores and two had poor water quality. Among all the ...
    • The Importance of Zn for Assessing the Impact of Heavy Metals in Urban Streams 

      Wenner, David B.; Miller, William P. (Georgia Institute of TechnologyInstitute of Ecology, 2003-04)
      Comparison of dissolved Zn, Ni, As, and Pb concentrations in highly and minimally impacted streams in Athens-Clarke County shows that only Zn is enriched in the impacted streams. This pattern is in part controlled by the ...
    • Low Flow Streams Conditions in Georgia 

      Nwogu, Peter C.; Booth, Elizabeth; McClelland, Bob; Burke, R.C. III (Georgia Institute of Technology, 2007-03)
      In Georgia, there are low flow streams that receive high quality domestic treated wastewater due to the increasing urban development. Municipal and industrial water pollution control plants (WPCP) often request a waste ...
    • Mercury Contamination of Stream Sediment in North Georgia from Former Gold Mines in the Dahlonega Gold Belt 

      Leigh, David S. (Georgia Institute of TechnologyCarl Vinson Institute of Government, 1995-04)
      Floodplain sediments downstream from 19th century gold mining sites were studied to determine if mining activities released toxic metals into streams. Mercury was found to be the only significant mining pollutant, and ...
