National Water Monitoring Day: "October 18, 2002 - Citizen monitors, established volunteer monitoring organizations, federal, state, Tribal and local monitoring staff are invited to participate in National Water Monitoring Day on October 18, 2002. Citizen monitors including families, classrooms, civic organizations and service clubs can participate and sample for a core set of water quality parameters (Temperature, pH, Water Clarity, Dissolved Oxygen) using an inexpensive National Water Monitoring Day test kit available through this web site. Established volunteer monitoring organizations and government monitors may use their existing protocols, equipment, and monitoring methods."
