What is Cadmium?

So what is it?

Cadmium is a natural element that's found within the Earth's crust. Because it does not corrode so easily it's often used in batteries. Other uses for cadmium include metal plating, metal coating, transportation equipment, pigments and plastic stabilizers.

Potential source of cadmium in local water: Industrial metalworking waste.

Is it toxic?

Although Cadmium occurs naturally and is found within soil and rocks, exposure to the metal at high concentrations is very toxic. Short answer: yes. 

What are the effects of arsenic exposure?

The EPA has listed averse health affects to short-term exposure as: nausea, vomiting, diarrhea, muscle cramps, salivation, sensory disturbances, liver injury, convulsions, shock and renal failure.

Long term exposure to high levels of cadmium include kidney, liver, bone and blood damage.

Is arsenic found in drinking water?

Yes. Cadmium may enter ground and surface waters due to in industrial waste and landfill leaching. Cadmium can more directly reach drinking water through corrosion of local plumbing. The EPA has set a maximum contaminant level (MCL) of Cadmium in drinking water at 5 parts per billion. 

what is cadmium and how does it get into drinking water

Landfills can leech potentially hazardous material into local waters.

How can you prevent arsenic exposure?

Immediate exposure can be curbed by avoiding the handling or tampering of batteries, industrial paints, waste, etc. Avoiding exposure to cadmium in water can be done using reverse osmosis or a rigorously lab tested home filtration filter.
