Concerns
Take sample below the first 10cm of the water. Rinse cup 3 times before taking your sample. Phosphate teststrips: Follow instructions on package. These should be used when you suspect rates above 0.01ppm (100ppb). - Dip strip in the sample - Wait 45 seconds - Compare results with colour scale - Record results - Take a photo of the strip on the reference card. Other test strips: - Dip strip in sample for 2 seconds - Compare results right away - Hold strip vertically and compare values for Alkalinity, pH and Hardness - Record results - Take a photo of the strip on the reference card For more information on the protocols of this program, visit https://waterrangers.ca/research
