Does ZeroWater Reduce Cadmium?

YES! When tested in accordance with the NSF's protocol based on a 40 gallon filtration (double the rated usage), ZeroWater removes 99% of Cadmium from your tap water.

The Premium 5-Stage Ion Exchange Water Filtration System reduces more contaminants than standard 2-Stage filters.

How does Cadmium get into your water?


Cadmium occurs naturally in many ores. For example Zinc, Lead and Copper ores can contain cadmium. It is also often found in coal and other fossil fuels. Furthermore Cadmium can be found in shales and is released during volcanic activities.

These deposits can serve as sources to ground and surface waters, especially when in contact with low total dissolved solids (TDS) and acidic waters.

Major industrial releases of Cadmium are due to waste streams and leaching of landfills. It is also produced as a by product of a variety of operations that involve Cadmium and/or Zinc. These may include many different types of industrial
operations.

Cadmium is often found in drinking water supplies as a result of deterioration of galvanized plumbing, along with industrial waste contamination, or surface water contamination by certain fertilizers...

Although it is possible for trace Cadmium to be chelated or sequestered as with any metal, it will generally be found in the dissolved ionic form.

Food is the major source of Cadmium in Humans. Leafy vegetables contain approximately 0.05 – 0.12 mg Cadmium/kg.

 

The Health Implications of Cadmium

Most test and countries monitoring Cadmium levels have established a Maximum Contaminant Level of around 0.005 milligrams per liter (mg/L) for Cadmium in drinking water.

Cadmium has the potentially to cause a variety of effects from acute exposures, including:

    • nausea
    • vomiting
    • diarrhea
    • muscle cramps
    • salivation
    • sensory disturbances
    • liver injury
    • convulsions
    • shock
    • renal failure

Drinking water levels which are considered "safe" for short-term exposures are: 

    • 0.04 mg/L for a 10kg (22 lb.) child consuming 1 liter of water per day for one-to ten-day exposures and  0.005 mg/L for a longer-term (up to 7 years) exposure.

How are the ZeroWater filters tested?

Test results as performed by 3rd party laboratory is based on NSF/ANSI testing protocol of pour through devices for contaminants listed under the National Primary Drinking Water Standards.

Contaminants were tested at the average Influent Challenge Concentration levels as established under testing protocols by contaminant type. Results shown are based on a 40 gallon filtration, double the rated usage to ensure consumer safety.

These results are calculated from an average of two pH's (6.5pH and 8.5pH) * Indicates NSF Certified Contaminant reduction percentages for ZeroWater. These results are calculated from an average of two pH's (6.5pH and 8.5pH) Testing performed Quality Filter Testing Laboratory, LLC located in Wilmington, DE. Quality Filter Testing Laboratory, LLC is an independent ISO 17025 laboratory certified by WQA and IAPMO to test water filters as per NSF/ANSI Std 42, 53, 58, 401, 473, P231.
