Domestic sewage.<\/p>\n<p>Domestic sewage is the wastewater that comes from homes and businesses. It contains a variety of pollutants, including heavy metals, which can contaminate water supplies. Heavy metals can cause a variety of health problems, including cancer, reproductive problems, and developmental problems.<\/p>\n<p>Paints can also contain heavy metals, but they are not a major source of heavy metal pollution in water. Wood burning can release heavy metals into the air, but these metals are not likely to contaminate water supplies. Acid plants can release heavy metals into the air, but these metals are also not likely to contaminate water supplies.<\/p>\n<p>Here are some additional details about each option:<\/p>\n<ul>\n<li>Paints: Paints can contain a variety of heavy metals, including lead, mercury, and arsenic.
