Oregon’s Pesticide and Water Quality Monitoring and Management Program Overview … . Basic Principles Program elements Statewide pesticide-related water quality team Watershed-based Pesticide Stewardship Partnerships (PSP) Water Quality Pesticide Management Strategy Budget Summary/Status Moving Forward and Key Challenges/Issues
Key points in Oregon’s approach to pesticide occurrences in water bodies • It is voluntary and locally driven • It is collaborative both at the state and local level • It is data driven - Water quality data - Pesticide characteristics - Pesticide management • It is based on “adaptive management” principles • It is supported by both state and federal agencies
Oregon’s Pesticide and Water Quality Monitoring and Management Program
How Did Oregon’s Water Quality Pesticide Program Begin ? Began in the Hood River Watershed in the early 2000’s to address Organophosphate (OP) insecticides detected above WQ standards - An alternative to a solely regulatory approach in dealing with pesticides in local water bodies With local support development of a coordinated voluntary program began that included: • State Agencies – DEQ monitoring • Locals - Growers, Extension, SWCD, Watershed Council, • Irrigation Districts & Confederated Tribes of Warm Springs Focused on development and implementation of Best Management Practices (BMPs) • Application Practices, Buffers, etc. • Outreach/Training • Technical expertise, resources & tools in place at local level All based on data collected within the watershed throughout the year

Successes in Fruit Growing Areas along the Columbia Hood River PSP: What Can Be Achieved? Goal: Reduction in concentrations & frequency of detections over time A result of IPM, alternative pesticides, improved application practices, monitoring, etc.
Expansion of the PSP Program As a result of Hood River success, additional pilot projects added in 2000s Legislature funded program beginning in 2013 Program supported by grant funding and in-kind contributions until 2013 - Between 2005 and 2015, nine watershed-based PSP projects were initiated Formation of State Water Quality Pesticide Management Team (WQPMT) in 2007 provided guidance and consistency to watershed projects
(86%) Only 2 sampling Cherry growers increasing use of events weather stations to reduce wind drift, during 2010 spray using more ground (rather than aerial) season spraying near streams, and rotating chemistry. (19%)
Irrigation District switched to mechanical control of vegetation, along with spot spraying of less toxic and persistent herbicide.

Areas of the State Where Pesticide Monitoring Has Occurred Each of the areas Indicated have petitioned the state to participate in the program known as the Pesticide Stewardship Partnership. Currently there are nine such areas with three Pilots that have been Conducted (or) are being conducted.

Water Quality Pesticide Management Team State Water Quality Pesticide Management Team (WQPMT) formed in 2007 to provide guidance and consistency to watershed projects

State Collaboration – The Water Quality Pesticide Management Team The WQPMT provides oversight for Oregon Pesticide Stewardship Partnership which fosters the implementation of the Pesticide Management Plan for Water Quality Protection through the: • Identification of potential concerns and improve water quality affected by pesticide use around Oregon. • Combine local expertise in water quality sampling results to encourage voluntary changes in pesticide use and management practices. • Find ways to reduce pesticide levels while measuring improvements in water quality and crop management. • Work toward measurable environmental improvements, making Oregon waters safer for aquatic life and humans.
The Water Quality Pesticide Management Team Pesticide Evaluation Per the Pesticide Management Plan for Water Quality Protection, an evaluation of all pesticides (of interest) in a state must be evaluated to assess whether they merit an action: 1) Further monitoring assessment 2) Additional education and outreach 3) Modifications in use practices 4) Additional restrictions in use 5) Elimination from use due to environmental concerns This is conducted by the WQPMT who designates a Pesticide of Concern or Pesticide of Interest
