Perchlorate Effects in the Water System

  1. 1. Heather Melendez HSCI 401 Advanced Environmental Health Dr. Mian 10 May 2016
  2. 2. Chemical compound (ClO4 -) Inorganic Salt Anion consisting of Chlorine and Oxygen Highly soluble and dissociates in water Migrates to groundwater & stable in water for years Strong Oxidizing Agent
  3. 3. Rocket Fuel Munitions Explosives Fireworks
  4. 4. Goitrogen disrupts the production of thyroid hormones by interfering with iodine uptake in the thyroid gland Most Susceptible People with preexisting thyroid deficiencies or iodide deficiencies, pregnant women, fetuses, infants
  5. 5. Thyroid requires iodide to synthesize (T4) and (T3) - hormones Regulation of cell respiration growth & maturation of body tissues Perchlorate-induced iodide deficiency hypothyroidism (↓ thyroid hormone production) goiter and developmental defects in fetuses
  6. 6. Military and defense contractors Linked to perchlorate water contamination Expended munitions, unused rocket propellant consumption Firework manufacturing Flare residue Leach into groundwater
  7. 7. 2013 – EPA screening level standards begin at a level of 11 µg/L for perchlorate and perchlorate salts 2015 – CA-EPA revised the Public Health Goal from 6 µg/L to 1µg/L
  8. 8. Regenerable and single-pass ion exchange Reverse osmosis Fixed- and fluidized-bed biological treatments Bioremediation by anaerobic microorganisms Dechloromonas
  9. 9. Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) Superfund Amendments and Reauthorization Act (SARA); Title I: Hazardous Substances Release, Liability and Compensation; Title III: Emergency planning and Community Right to Know (EPCRA)
