Types of Drinking Water Contaminants

Pure water does not exist anywhere in nature and there are impurities in all water. The natural cycle of water flow moves it down streams and rivers, through lakes and down into the earth. As it flows and is filtered through the soil and rocks, it absorbs at some level, any substance it comes in contact with.

Home Water Testing

A lot of the substances are harmless and in fact some are needed by our bodies for good health. Minerals and metals are necessary and water can provide some of our body’s requirements for these.

However, as with anything else, too much of anything is not good for you. As the levels increase, the same substances can change the taste of the water and potentially make the water unhealthy to consume. In addition to these naturally occurring elements, man-made chemicals and organics, such as bacteria, can also be picked up in the water as it travels through the cycle.

Discharges from factories, pesticides applied on farms and nursery and even chemicals used by homeowners in their homes or yards can be a source of contamination. To monitor the safety of drinking water, the EPA has established guidelines for some of the contaminants found in drinking water.

Primary and Secondary Levels of Contaminants

The National Primary Drinking Water Standards were developed to set safe levels for contaminants that cause health issues such as disease, cancer or illness.  These standards are mandatory for public water supply systems, but not on private water systems.

The National Secondary Drinking Water Standards are guidelines for regulating contaminants that more nuisance or aesthetic in nature. These contaminants can affect the taste, color or odor of the water. They can also cause stains on surfaces, clothes and sometimes skin or teeth. These standards are non-enforceable guidelines recommended by the EPA to water systems but do not require systems to comply. However, states may choose to use them as enforceable standards.
