Thanks to my good
buddy Jazz
for helping me
figure out my topics
for this presentation
                                              Coming soon to a
                                              water body near you?!

             To join the Pharmwaste list serve: go to
                     and follow the directions

Or drop me an email and I’ll send you the link (the easy way)
Today’s topics

• Analyzing for EPOCs or PhACs or Micro
  constituents – different groups have
  different acronyms & focuses
• What happens at the waste water
  treatment plant?
• The legacy of a family-owned pharmacy
                   How much?
    “Typical occurrence is <100ng/L (<0.1μg/L)”
• 1 part/million = .001g/L or
    1mg/L or 1 mg/kg or 4 drops
    of ink in a 55 gallon drum
•   1ppb = .000001g/L or 1μg/kg
    or 1μg/L or 1 pinch of salt in
    10 tons of potato chips
•   <100ng/L (<0.1μg/L) =
    concentration many PhACs (or
    whatever you want to call
    them!) occur =<0.0000001g/L
    or <1 pinch of salt in 100 tons
    of potato chips
        Methods Development
   analytical determination in environmental samples is
            difficult and involves multiple tasks

• Sample collection - possible contamination
• Separation & Extraction
• Concentration
• Detection & Quantification
• Many methods for doing all these things –
 methods development is time consuming &
 expensive – usually for one compound at a
            Analytical Methods
• GC/MS – Gas Chromatography/ Mass
•   HPLC/MS – High Performance Liquid
    Chromatography/ Mass Spec.
•   LC/MS – Liquid Chromatography/Mass Spec.
•   Combinations of these things in sequence
•   Different compounds require different analytical
•   QA/QC – Quality Assurance/Quality Control is
    very difficult
       Obstacles to Analysis

• Test for each compound separately
• Very low detection levels may require
  putting analytical equipment in sequence
• Few labs are capable
• Cost prohibitive
• Removal, reduction, or alteration of
 pollutants in industrial wastewater prior to
 discharge or introduction into a domestic
 wastewater treatment facility
      Standard Pretreatment

• Primary – filtration for particulates
• Secondary – oxidation introducing bacteria
     (can also be aerobic)
• Tertiary - chlorination
Advanced Treatment Technologies
• Coagulation/Flocculation
   – >50% removal of PAHs
   – <40% removal of organic chemicals
       • pesticides, steroids, inorganics, industrial chemicals
• Softening
   – 70-90% removal of pesticides
   – <20-40% removal of industrial chemicals and steroids
• Chlorine
   – 70-90% removal of pesticides and other organics
   – <20% removal of inorganics, industrial chemicals
• Ultraviolet
   – >90% removal of pesticides, industrial chemicals, and steroids
   – <20% removal of inorganics
               New Technology
• Activated Carbon – good at removing 17a-
    ethynylestradiol (EE2) but expensive
•   MnO2 – Manganese oxide – also good for EE2, increases
    degradation rate for others
•   Membrane Filtration - semi-permeable polymeric
    membrane - $$$$
•   Membrane Bioreactors – adds bio-substrate – pesticides,
    herbicides, EDCs - $$$$, lots of maintenance
•   Fenton process, Advanced Electrochemical Oxidation
    Process, Phytoremediation – now you’re getting really
AFTER Pretreatment
•   Aerated, Partial Mix Lagoons
•   Anaerobic Lagoons
•   Ammonia Stripping
•   Ballasted Flocculation
•   Chemical Precipitation
•   Dechlorination
•   Granular Activated Carbon Absorption
•   Oxidation Ditches
•   Trickling Filter Nitrification
•   Trickling Filters
•   Etc!
The best way to treat them?
