Damage to central nervous system (by Phthalates)

Intestinal disorders (by Polychlorinated biphenyls)

Anaemia, bone marrow damage, leukaemia (by Benzene)

Disorders of liver, bone and circulatory system, birth anomalies (by Vinyl chloride)

government standards
Government Standards

The Safe Drinking Water Act

U.S. Environmental Protection Agency (EPA) sets standards for drinking water quality and oversees the states, localities, and water suppliers who implement those standards.

The U.S. EPA has set standards for more than 80 primary contaminants that may occur in drinking water and pose a risk to human health

where does water come from
Where does Water come from
  • Snow and rain runoff from the watersheds in Arizona
  • Several dams
  • Colorado River
government responsibilities
Government Responsibilities
  • Ensuring that Arizona\'s public water systems deliver safe drinking water
  • Identifying water pollution problems and establishing standards to address them
  • Investigating complaints and violations of Arizona\'s water quality laws, rules and permits
  • Issuing permits to protect Arizona waters from point sources of pollution
  • Managing the quality of water resources through partnerships within the natural boundaries of the state\'s watersheds
  • Monitoring and assessing the quality of surface and groundwater throughout the state
  • Regulating the discharge and treatment of wastewater
water quality division
Water Quality Division
  • water quality permits
    • Safeguard Arizona’s waters that are affected by pollutants that come from an identifiable source.
    • For example: The Groundwater Section & Surface Water Section
tradable water permits
Tradable Water Permits
  • Firms are allowed “purchase pollution reduction credits from other sources that can generate the same reductions at a lower cost, thus achieving the same or better overall water quality improvement” (EPA).
  • Currently operating in seven states across the nation, in the development process in four other states.
arizona water trading programs
Arizona Water Trading Programs
  • No state trading programs in Arizona
  • Few independent water quality trade initiatives in Arizona
    • For example, a mining company cleaned up an abandon mine with the conditional trade of copper loading that was being released from the companies new mine
