Dissolved Contaminants: Dissolved substances are usually individual atoms, molecules or ions (molecules that have gained or lost one or more electrons).
- Inorganic: Compounds that
typically do not contain the element Carbon. They can
become dissolved in water from natural sources or as the
result of human activity.
- Organic: These compounds all
contain the element Carbon. Although there are many
exceptions, naturally occurring organic compounds
(sugars, proteins, alcohol's, etc.) are synthesized in
the cells of living organisms, or like raw petroleum and
coal, formed by natural processes acting on the organic
chemicals of once living organisms

Suspended Contaminants: Water molecules are in constant motion - hurtling around ricocheting off each other and any other substances that might be in it. Small organic, inorganic or living particles keep getting knocked around in random directions by these water molecules, and if they are small enough, this motion is enough to keep gravity from pulling them down and they remain in suspension - like a never ending soccer game with no goals.
- Pathogens: Disease causing
organisms including, viruses, bacteria and protozoa.
- Algae: Algae (or
phytoplankton) are a type of aquatic plant (has
chlorophyll and are capable of photosynthesis).
- Asbestos: Asbestos is a
mineral that forms minute fibers in the environment.

Water Contaminant Risks: Although water companies in the US and many other countries are strictly regulated and the treated water must meet certain minimum purity and safety standards, all water companies are not created equal.
You can reasonably assume that most are doing the best they can with the resources available to them - if for no other reason than to keep their name out of the evening news.
In general, though, the larger water companies (in the US anyway) have greater resources available to treat and distribute the water and maintain the distribution infrastructure. And, because they serve more people, they are required to meet stricter regulations.

Water Sources:
The geographic region where people live is an important contributing factor to both the quality and availability of fresh water. |
