Emerging contaminants in the Great Lakes present a new threat to human and ecological health due to chal- lenges associated with tracking and understanding their impacts. The workshop presenters will discuss how large water and wastewater utilities approach the issue of emerging contaminants, highlight the challenges, and provide recommendations for future action. This presentation was given by Olga Lyandres, Research Manager, Alliance for the Great Lakes.

    • Priori%es  for  Protec%ng  the  Great  Lakes   against  Emerging  Chemical  Pollutants   Healing  Our  Waters  –  Great  Lakes  Restora5on  Conference   Milwaukee,  WI   September  11,  2013   Olga  Lyandres     Research  Manager   Olyandres@greatlakes.org  
    • A  Community  that  Cares  for  the  Great  Lakes   Formed  in  1970,  the  Alliance  for  the  Great  Lakes  is  the  oldest  independent   Great  Lakes  ci5zens'  organiza5on  in  North  America.    Our  community   today  includes…   •  •  •  •  •  •  •  •  Individuals   Businesses   Elected  officials   Teachers  and  students   Environmental  advocates     Policy  leaders   Recrea5onal  enthusiasts   Civic  organiza5ons   The  Alliance  is  the  only  independent  policy  organiza5on  working  solely                                     to  improve  the  Great  Lakes  every  day.    
    • The  Alliance  at  a  Glance   Mission      To  conserve  and  restore  the  world's  largest   freshwater  resource  using  policy,  educa5on   and  local  efforts,  ensuring  a  healthy  Great   Lakes  and  clean  water  for  genera5ons  of   people  and  wildlife.   Core  Issues   –  Clean  water   –  Sustainable  water  use   –  Ecosystem  restora5on   –  Emerging  threats   –  Invasive  species   –  Educa5on   –  Civic  and  youth  par5cipa5on,  e.g.  Adopt-­‐ a-­‐Beach™    
    • Public  Health  and  Environmental  Threats   •  Endocrine  disrup5on   •  Toxicity  of  metabolites  and   byproducts   •  Resistant  bacteria   •  Bioaccumula5on  in  aqua5c   food  webs   •  Low-­‐level  chronic  exposure   •  Synergis5c  effects  of  chemical   mixtures     Limited  informa%on  on  fate,  persistence,  epidemiological  and   ecological  effects,  for  mixtures  of  chemicals  and  their  byproducts  
    • Clean  Water  and  Emerging  Contaminants    Alliance’s  goals  include:   –  Curbing  unintended  drug  releases   into  the  environment   –  Suppor5ng  further  research  and   monitoring  of  contaminants’  fate   and  impact  in  the  Great  Lakes   –  Evalua5ng  methods  to  op5mize   removal  efficiencies  in  water  and   wastewater  treatment  systems   –  Priori5zing  chemicals  of  concern   for  control   –  Advoca5ng  for  comprehensive   chemical  management  reform  
    • Great  Lakes  water  cycle:     mul5tude  of  point  and  diffuse  sources   •   The  Great  Lakes  and  their  tributaries  serve  as  receiving  waters  for  1,448  municipal   facili5es  discharging  4.8  billion  gallons  of  effluent  daily  and  2,393  industrial  facili5es   repor5ng  to  the  EPA’s  Toxic  Release  Inventory   •   85,000  chemicals  in     the  Toxic  Substance     Control  Act  inventory       • 20,000  registered   pes5cide  products   • 56,000  pharmaceu5cals   for  human  use   •   1,000  for  veterinary      use
