Heavy metals: Why your drinking water may be slowly killing you

Heavy metals are found all over the earth and for hundreds of years they have been harvested for industrial purposes. However, not many people would consider their tap water as a primary source of heavy metal exposure. Unfortunately, research has shown that heavy metals are lurking in our public drinking water and causing serious health concerns (1).

Health Risks of Heavy Metals


Long-term exposure to heavy metals can cause a number of health problems, especially in children and unborn babies. This can include physical underdevelopment, cancer, nervous system damage, organ damage, reduced energy levels as well as neurological degeneration (2). Exposure to mercury and lead specifically can cause autoimmunity, where the immune system attacks its own cells leading to rheumatoid arthritis, kidney disease or nervous system problems (3). 


Children, infants and foetuses are more sensitive to heavy metal exposure. This is due to the rapid development of their bodies, which can be disturbed by the toxins in heavy metals. In children, exposure can cause growth problems, learning difficulties, memory impairment, nervous system damage and behaviour problems like ADD or ADHD (4). Extreme exposure can cause irreversible brain damage (5).


Santevia’s countertop and pitcher filters are able to remove up to 99.9% of the heavy metals from your tap water. Santevia adds calcium, magnesium and other beneficial minerals, and has been independently tested to reduce chlorine taste and odour, heavy metals, industrial chemicals and agricultural contaminants.

What Are Heavy Metals

Heavy metals are natural formations within the earth’s crust. However, just because they are natural does not mean they are good for us. There are 50 elements that are categorized as toxic heavy metals and of these, 17 are classified as very toxic. Some of these metals you would have heard of include arsenic, lead, mercury, dioxin and cadmium. Each element has a different toxicity level and biological role.

Within these 50 elements, there are a number of heavy metals or minerals which are actually healthy and essential for the body. These include copper, zinc, manganese and iron. In small doses these metals are beneficial, but in large doses they can also be toxic (6).

Where Do Heavy Metals Come From

Heavy metals enter into our water system in two ways; firstly through industrial, municipal and urban run off and secondly through seeping into underground water supplies. This is damaging to human health, animal health and the environment. The constant expanding of industrialization and urbanization are responsible for the prevalence of heavy metals in our waterways.

Types of Exposure

Public Water: Heavy metals can enter the public water system through industrial run off as well as possible underground contamination. When heavy metals are ingested over a period of time, they can build up, causing various health problems.

Inhalation: Heavy metals can enter the air through emissions from smelters, coal burning factories, waste incinerators and mining extraction as well old house paint and plumbing.

Food Consumption: Heavy metals can enter into soil through natural contamination or industrial waste. This can then infect foods grown in soil, such as vegetables, grains and fruits (7).
