  2. The human impact on aquatic ecosystems is extensive in magnitude, scope and duration. From over depletion to blatant source pollution, humans have been degrading water quality and depleting the quantity of potable water for centuries. The impacts are beginning to intensify, and are not easily remedied.

  3. Previous Regulations Protect aquatic system from: DDT Mercury

  4. There is a new class of Contaminants Pharmaceuticals & Personal Care Products • Widespread • Long term effects unknown on ecosystem • “Impossible to Regulate”

  5. Rivers, Lakes & Aquifers IN DANGER

  6. Sources: Agriculture & Hospital Waste

  7. EU Implementing Regulations World Leader Banned exports of Mercury Enforce Recycling of batteries Required risk assessment of all new medicines USA “Recognized” as “possible threat” NO legislations to regulate everyday contaminants at present Lack of funding due to military spending and no market incentive EPA 2007 “lack of studies to determine long term threats” European Union vs United States

  8. How clean is our water? Present regulation doesn’t regulate every day contaminants, which have a cumulative effect: BIOACCUMULATION

  9. Waste / accumulation increase with population & usage increase.

  10. kills beneficial organisms creates super viruses Homes Animal Feedlots Veterinary Clinics Antibiotics prostate & breast cancer link Steroids (Hormones) CAFOs http://www.themeatrix1.com/

  11. CAFOs • Over 238,000 operating in US • Count for over half of the 500,000,000 tons of manure through feeding operations • Natural and synthetic hormones are spread into local water and soil by runoff. • They are overly destructive in the ecosystems they contaminate. One study showed the masculinization of female fish downstream from a CAFO in 2004.

  12. Hospital Waste Regulated by • OSHA • EPA • DOT • State of Missouri Practices not consistent between hospitals. *in house vs. contracted processing/storage *different levels of preparedness/willingness to discuss

  13. MUST ACT NOW! • Long term effects unknown • Cumulative damage Must regulate/control disposal & waste streams.
