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

This 5-Year Nonpoint Source Management Plan will guide and direct ADEQ's activities for state fiscal years 2015 – 2019 and fulfills the requirements of Section 319 of the Clean Water Act. The plan comprehensively describes a framework for agency coordination and cooperation and describes strategies for employing effective management measures and programs to control nonpoint source pollution statewide.

The overall mission Arizona’s NPS Program is: "To achieve and maintain water quality standards through the reduction of nonpoint source pollutant contributions to Arizona’s surface and groundwater." Four goals are established in this 5-year Plan to achieve this mission:

  • Identify impairments to surface and groundwater quality
  • Prevent and reduce NPS pollution discharges to protect and restore surface or groundwater resources
  • Coordinate efforts of various programs within ADEQ and with other agencies and partners to prevent and reduce NPS impacts to surface and groundwater
  • Evaluate and improve the effectiveness of the nonpoint source pollution program and communicate success

Each of these goals has specific objectives and strategies (identified in the Strategic Planning Table, found in Chapter III of the plan) that will be implemented in order to achieve measurable outcomes over the next five years. Measures of success will include removing waters from the state 303(d) list, satisfying existing ADEQ and EPA performance measures, and increasing the quantity and quality of grant applications in Targeted Watersheds. More information on how ADEQ will specifically measure its success in implementing this plan can be found in Chapter I Section IV.

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.
