What is contaminating your water

The Safe Drinking Water Act defines the term “contaminant” as meaning any physical, chemical, biological, or radiological substance or matter in water. Therefore, the law defines “contaminant” very broadly as being anything other than water molecules.

Drinking water may reasonably be expected to contain at least small amounts of some contaminants. Some drinking water contaminants may be harmful if consumed at certain levels in drinking water while others may be harmless. The presence of contaminants does not necessarily indicate that the water poses a health risk. It makes sense that every home should have an effective water filtration system.

Instead of doing a basic ZeroWater vs. Brita analysis we researched as many as 7 water filters including the two mentioned to see how they handle contaminates. Cadmium is a toxic heavy metal which can cause kidney damage, heart damage and hardening of the arteries. Cadmium removal ranged from 6.6% (Brita) to a high of 99.2% (Zero Water). The average removal was 33.1%.Lead is a toxic heavy metal that causes brain damage and organ damage in the human body. Lead removal ranged from a low of 14.1% (Brita) to a high of 93.7% (Waterman Mini).Average lead removal was 52.5%.In its non-radioactive form, strontium is a bone-building nutrient that’s often found with calcium. Some water filters removed almost no strontium (Brita and Mavea), while the Zero Water Filter removed 100% of strontium. One filter, the Waterman mini, increased strontium concentrations in the resulting water, indicating use of strontium in the filter media. This is not a bad thing. Strontium is actually a nutritive mineral, much like calcium.
