Again, a type of sequestering agent can be used to help with the screening of metals out of the water. It totally depends on what your drinking water plant is adding. In any event, ever since the Flint Michigan water crisis in 2014, virtually every drinking water facility in the U.S. treats the water with some form of phosphate.

In nature, rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants. The solubility also depends on the type of rock containing the phosphorus and the pH of the soil; phosphorus is most soluble when contained in sedimentary rocks as opposed to igneous rock, and ...
