World Water Monitoring Day – September 18, 2012

World Water Monitoring Day (WWMD) is an international education and outreach program involved in testing water sources and reporting results in an international database. Last year, approximately 340,000 people in 77 countries monitored their local waterways.

This was JWP’s third year of introducing Harborview Elementary students to Gold Creek and WWMD water testing. WWMD is a great activity for kids to build awareness of water quality by studying the importance of water in their daily lives. WWMD is also a good way to introduce  fourth-grade students to the water cycle and watershed health. 

JWP board members Amy Sumner, Adelaide (Di) Johnson, and Erik Norberg welcomed the children at three different stations. At the stations at, students observed a benthic macroinvertebrate index, sediment transport, and indicators of water quality along with measurements of water discharge. At each station, students applied what they learned in order to determine the relative health of Gold Creek:

  • At the water quality and discharge station, participants learned firsthand about water quality by testing  four basic parameters of water quality including pH, turbidity, temperature and dissolved oxygen. These results were entered into the WWMD database.
  • At the benthic macroinvertebrate station, students were able to identify aquatic insects. Based on the species present, the students determined if the stream supported a productive habitat and had good water quality.
  • At the sediment transport station, students experimented with slope, sediment size, and stream flow. Students evaluated suspended sediment, sediment movement, and changing channel pattern.
