How do I test for red muddy water or reddish staining?
In most cases red material tests as iron, not mud. Iron can cause staining of fixtures. If the water is reddish we recommend an iron / sediment test. In many cases, the reddish color is due to a condition referred to as biofouling, where bacteria in the well feed off of nutrients in the well and over time produce the reddish water. This is usually addressed by cleaning the well, lining the well casing and placing the well pump at an optimum location in the well. Other culprits of red water are iron bacteria. There is a standard test to determine the presence of iron bacteria.
