– Arsenic Because Arsenic is a common element found in the earth’s crust, it is most often found in drinking water due to natural erosion through soil and rocks. However, it does have industrial purposes that can lead to higher concentrations of runoff from industrial processes. Early effects of Arsenic poisoning are stomach pain, vomiting and diarrhea. Long term effects include heart, nervous system, lung, liver, immune, and reproductive disorders, diabetes and cancer.
Arsenic can only be identified by testing. While testing of private drinking water wells has federal requirements for community testing, routine testing for arsenic levels is not mandated in those requirements. Combine that with the fact that the Western US has higher concentrations of arsenic and it is clear that getting your well water tested for Arsenic is very important.

– Cadmium For people who are exposed to levels of cadmium above the MCL over relatively short periods of time, health effects include: nausea, vomiting, diarrhea, muscle cramps, liver injury, convulsions and renal failure. If exposed to cadmium over the long term however, effects from exposure to levels above the MCL include kidney, liver, bone and blood damage.
– Chromium Chromium exists in two states, both in water and in the human body. While trivalent chromium (Cr III) is the most common naturally occurring form and is an essential nutrient, it’s counterpart hexavalent chromium (Cr IV) is known to cause cancer and kidney, liver or nervous system damage when inhaled or ingested. While Federal EPA standards have set the MCL at 100 PPB for total chromium, scientists from the California Office of Environmental Health Hazard Assessment recommend a goal of 0.02 PPB of hexavalent chromium for drinking water as a matter of public health.
– Copper While small amounts of copper are necessary for our health, consuming higher levels in drinking water, where it can collect due to corroding pipes, causes stomach cramps, vomiting and diarrhea especially in young children. Consuming too much copper can also lead to kidney and liver damage.

– Lead Of all these toxic heavy metals in water, lead is perhaps the most well known toxin to humans and animals, causing damage to the brain, liver, kidneys and bones. Lead poisoning is particularly concerning for children since they need more water despite the smaller size of their bodies and can suffer from lead poisoning and its effects from early in life. Because lead is a common resource, malleable, and corrosion resistant, it was used in water pipes for many years and is still used today (though in limited amounts). If you have an older home or are connected to an old water system it is wise to test your water for lead. No amount of lead in drinking water is considered safe.
– Manganese This naturally occurring metal has a wide range of uses in industrial applications and is actually an essential nutrient for the human body in very small doses. However, when it is consumed in larger amounts it poses long term toxic health problems especially for the central nervous system. The best way to discern whether your water has high levels of manganese is to get your water tested in a lab. They can also help you determine what method of remediation will best remove this heavy metal from your drinking water.
– Nickel Most commonly, nickel in water is associated with skin irritation. Studies have shown that 10-20% of the U.S. population has a nickel sensitivity that leads to a rash or other dermal irritation after taking a shower or bath in water containing elevated nickel levels. In high doses nickel can also cause cancer. Elevated levels of nickel in drinking water are almost always a result of mining and smelting.
