Water Quality Division: Watershed Management: Nonpoint Source Pollution Reduction

Arizona's Nonpoint Source Program gathers information, monitors and focuses on the following land use activities that can negatively impact surface and groundwater within the state.

  • Agriculture
  • Forestry
  • Urban runoff
  • Hydromodification
  • Onsite/septic waste treatment systems
  • Mining
  • Recreation

ADEQ's Nonpoint Source staff work with local stakeholder groups and land management agencies to develop implementation plans to reduce sediment and nutrient loads from nonpoint sources and help impaired waters attain water quality standards.

Arizona's 5-Year Nonpoint Source Management Plan

The plan will guide and direct ADEQ's activities for the next five years (2010 through 2014) and fulfills the requirements of Section 319 of the Clean Water Act. The plan comprehensively describes a framework for agency coordination and cooperation and serves to implement a strategy for employing effective management measures and programs to control nonpoint source pollution statewide.

A combination of tools, such as surface and ground water monitoring, watershed inventories, watershed characterizations, Total Maximum Daily Load (TMDL) studies, TMDL implementation plans, watershed-based plans, and water quality improvement projects, will be used to protect the state's water resources from nonpoint source pollution. With improved coordination, collaboration and combined agency and local stakeholders efforts working to implement measures outlined in this plan, nonpoint source pollution can be better managed and controlled at both statewide and community levels.

Arizona's Nonpoint Source Management Plan integrates the state's Clean Water Act and Safe Drinking Water Act programs with voluntary incentives. ADEQ uses a combination of tools to protect the state's water resources from nonpoint source pollution. These include:

  • Surface and Ground Water Monitoring
  • Watershed Inventories
  • Watershed Characterizations
  • Total Maximum Daily Load (TMDL) Studies
  • TMDL Implementation Plans
  • Watershed-based Plans
  • Water Quality Improvement Projects

Arizona's 2013 Nonpoint Source Program Annual Report

The report is an overview of ADEQ's Nonpoint Source Program's activities for fiscal year 2013 (July 01, 2012 - June 30, 2013). A majority of the work performed is funded by Clean Water Act Section 319(h) grants, awarded by the U.S. EPA. Section 319(h) of the Clean Water Act requires states to report annually on progress in meeting the schedule of milestones contained in their nonpoint source management plans, and report reductions in nonpoint source pollutant loadings and improvements in water quality resulting from program implementation.
