An inquiry-based approach to watershed education and a great tool for beginning a school-based, community-involved, water-monitoring program. This kit utilizes the same safe, economical TesTab® method of water testing as our GREEN Water Quality Monitoring Kit (item# 652567). Each module contains easy-to-read, bilingual (English/Spanish) instructions with diagrams; a color chart; a test factor flash card; and the necessary apparatus to perform 100 tests for biochemical oxygen demand, dissolved oxygen, nitrate, pH, phosphate, and temperature; 44 tests for coliform bacteria; and unlimited testing for benthic macroinvertebrates and turbidity.
