The Napa Sanitation District provided funds and participated in the Watching Our Watersheds and Closing the Loop training seminar. This was a two-day training workshop for Napa County educators. There were 15 educators that attended the WOW conference. The Pollution Prevention and Source Control Officer attended the workshop on both days and provided some training on the second day of the workshop as described below. The Watching Our Watersheds program encouraged water pollution prevention through a focus on household hazardous waste reduction. Conducted over two days; April 5 & 12, 2003 and consisting of 15 hours of teacher training, the workshop enabled educators to use classrooms, schoolyards, creeks, gardens, households, and communities as settings for doing pollution prevention and waste reduction education. During the first day, teachers were introduced to the watershed concept and the topics of urban runoff pollution and hazardous waste. Teachers participated in hands-on activities they can use in the classroom, and they traveled to a nearby creek to sample water quality and aquatic macro invertebrate communities. In the process, teachers gained a direct perspective on the impacts human activities can have on urban watersheds and aquatic environments.

The Watching Our Watershed workshop's second day concentrated on the school and schoolyard habitat. Teachers learned how personal choices – for example, what cleaning supplies are purchased, if and how pesticides are applied, or whether or not to compost – can have considerable environmental effects. Teachers discovered how to create native plant gardens that are compatible with human health and ecosystem needs, propagate native plants for restoration or schoolyard habitat projects, and investigate integrated pest management techniques. The teachers were given an indoor tour of Soscol Water Recycling Facility (due to heavy rains). The Treatment Facility PowerPoint Presentation and EnviroScape Watershed Model were presented to the educators as well.

At the conclusion of the Watching Our Watersheds program, teachers gained the knowledge and tools they needed to develop student activities that improve water quality and reduce household hazardous waste. Teachers were encouraged to conduct outreach projects with their students in order to educate the broader community about ways they can protect water quality and prevent pollution by setting aside dedicated project planning time during the workshop’s second day. During this time, teachers were given the opportunity to solicit suggestions and advice from the Aquatic Outreach Institute and come up with their own waste reduction and pollution prevention outreach project or activity. Participants received a 400+ page activity and resource binder to help them tap into local community resources and jumpstart their pollution prevention curriculum. In addition, stipends are paid to participating teachers who carry out and document a water pollution prevention education or outreach project they have carried out with their students.
