• Abstract:
  A comprehensive research program for the characterization of storm water runoff from an Arizona
  
  highway was conducted from January through December 2007. The study area covered a portion of
  
  the Loop 202 freeway west of Mesa Drive to a retention basin east of Lindsay Road in Mesa, Arizona.
  
  Storm water samples were collected from two storm water detention basins and a discharge point to
  
  the Salt River. The study was conducted by manually collecting storm water samples with passive
  
  automatic samplers and analyzing them for various roadway constituents. A primary objective of this
  
  research effort was to establish baseline values of constituents in ADOT highway runoff, aiding in the
  
  evaluation of related best management practices.
  
  A total of 16 storm water samples was collected from the research area between January 2007 and
  
  December 2007. The storm water sampling data indicates suspended solids (reported as total
  
  suspended solids, or TSS) were present in 14 of the 16 samples collected and zinc (reported as total
  
  zinc) was present in 13 out of 16 samples collected. Other heavy metals such as copper, lead, and
  
  chromium were occasionally detected. Phosphorous and ammonia were detected only once during
  
  this research program. TSS is the most significant pollutant, by mass, found in our nation’s
  
  waterways, a standing consistent with the outcome of this research. It is important to note that
  
  exceedance of an Environmental Protection Agency benchmark does not constitute a storm water
  
  violation
