In the video above, we have given 2 options on the correct way to conduct a water test – one taking water directly from the tank and the other taking water from the tank tap. Taking a sample directly from the tank will give the most accurate reading. This eliminates the chance of any readings being skewed by any biofilm and bacteria that may be growing inside the tap or other fittings from which the water is pulled. When analysing water results, the coliform counts (as opposed to heterotrophic plate counts) are a better indicator to test the sanitary conditions of water. More information on this will be provided in upcoming blog posts.
