A private well is susceptible to quality issues, including the color, clarity, taste, smell, and health issues: Certain geographical locations can be known to have common water problems. Also, plants accumulate metal ions that destroy the cellular ionic homeostasis. The basic reasons are natural as well as anthropogenic. Toxic metals are a threat for both terrestrial and aquatic ecosystem. Other heavy metals are moreover essential nutrient, for example, iron, cobalt, and zinc some comparatively less dangerous such as ruthenium, silver, and indium; but can be toxic in the larger amounts or in their definite form [2].
