Water major use category

8 million acre-feet or 2.3 trillion gallons annually

Diseases that can be spread by chemical

pollutantsSkin infections

Carcinogenic problems (by Nitrosamine)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)

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

Government Standards

8

Where does Water come from

• Snow and rain runoff from the watersheds in Arizona

• Several dams

• Colorado River

9

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

Government Responsibilities

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

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

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

Suggestions

Preventing leakage of lubrication oil into rivers or lakes.

Promoting clean production and built high-tech industry to reduce waste and pollution

Building man-made water flow management system to enhances the self-purifying ability.

Setting the inspected program to check water situation.

Issuing permits to protect water sources.
