The Marion Soil and Water Conservation District (SWCD) has partnered with the Oregon Department of Environmental Quality (DEQ), OSU Extension, the Oregon Department of Agriculture (ODA), agricultural businesses and producers to identify and voluntarily reduce sources of off-target chemical inputs to local streams. This cooperative partnership, the Pudding Pesticide Stewardship Partnership (PSP), is one of many PSPs formed and promoted by the Oregon DEQ as a way for local communities to voluntarily support their watershed and industry by reducing chemical impacts to streams to meet water quality criteria and avoid additional agency regulatory actions. Since these efforts began in 1999, there have been significant steps forward in identifying and improving water quality associated with pesticide use at a local level. Oregon DEQ has been sharing results of pesticide sampling in the Pudding basin with stakeholders since 2005, and with the participation of partners and the agricultural community, there have been steady reductions in detections or levels for some of the pesticides of concern in the basin such as the insecticides Chlorpyrifos and Guthion (azinphos-methyl).

As a result of this partnership effort, Marion SWCD has been involved in many educational forums to outreach practical Best Management Practices and Integrated Pest Management. We have also co-sponsored and partnered in five Agricultural Waste Collection Events, where "legacy" pesticides such as DDT and Chlordane as well as excess or unusable restricted-use pesticides were disposed of at no cost to the participant. All five events combined collected in excess of 100,000 lbs. of pesticides from over 200 participants.
