Summary
Tap water can contain compounds that negatively impact our health, including endocrine disruptors and disinfection by-products (DBPs). The concentration of minerals, such as magnesium and calcium, can also vary in tap water. Fluoride in tap water, even at low concentrations, can disrupt thyroid function. Simple and inexpensive steps can be taken to make tap water safe to drink, such as filtering to remove contaminants.
