Occurrences of priority substances in selected catchments

  1. 1. Occurrences of Priority Substances in Selected Catchments L. Jones, B. Kinsella, A. Furey, F. Regan
  2. 2. Outline •  Project aim •  Sampling plan and catchments •  Rainfall data •  PAH levels •  Total Suspended Solids
  3. 3. Project Outline •  Monitor   priority   pollutant   levels   in   wastewater  treatment  plant  ef4luents •  SPE,  GC-­‐MS,    LC-­‐FLD/MS,  ICPAES •  Relate  levels  detected  to  emission  factors •  Population  equivalents,  rainfall,  traf4ic,  etc.   •  Create   model/index   of   priority   substance   emissions   from   wastewater   treatment   plants
  4. 4. Priority Substances in Wastewater •  Wastewater  major  point-­‐source   •  Responsible  for  localised  EQS  exceedances •  Often  upstream  of  drinking  water  abstraction •  Can  be  controlled •  Few  data  on  wastewater  PS  discharges   •  Will  complement  storm  water  studies,  and   inform  targeted  PS  monitoring
