I was shocked after reading about this. As Seattle school children began the 2003-2004 school year, school officials in Seattle wrestled with a problem. Testing performed on the water at the City's public schools had uncovered the presence of lead in that water. School authorities could not expect the students to be drinking lead-laden water.

The school authorities in Seattle needed to study the available pure water systems. They had to select a system for installation in the area's public schools. The authorities scheduled a meeting on pure water systems. They hoped to hear public comments regarding the proven effectiveness of each available purification system.

By October of 2004, the Seattle authorities had chosen the purification system that seemed to be both effective and economical. In making their selection, those authorities ignored some important information about pure water systems. They failed to consider what new contaminants might later appear in the water that was pumped into the public schools.

The system chosen by the Seattle authorities lacked the ability to remove cadmium, and yet later testing later identified the presence of cadmium in the water. By May of 2005, the chosen water purification system had proven to be even less effective. By May of 2005, new testing had revealed unhealthful levels of arsenic in the water that students would be drinking.

The parents in Seattle no doubt hope that their children pay better attention to what they read and hear than the school authorities in Seattle have managed to do. Had those authorities taken the time to read about water purification, they would have known that not every system removes all of possible contaminants in city water.

Carbon filters can remove organic compounds, chlorine and toxic heavy metals. Carbon filters can not take-out all of the minerals salts or nitrates. Arsenic is a type of mineral salt.

Reverse osmosis has the ability to lower the amount of heavy metals and dissolved salts in a water system. Reverse osmosis can not rid a water system of fluoride, nitrates or radioactive particles. Moreover, systems that rely on reverse osmosis often show diminished performance within six months after their installation.

Distillers can provide a school system with effective water purification technology. Unfortunately no school system will ever find an effective and cheap distiller. Moreover, the maintenance costs add to the total cost for each distiller. If not maintained properly, distillers can allow asbestos fibers to enter the water supply.

American school systems have access to literature from the National Institutes of Health. According to that literature, water sources in the U.S. can contain a broad spectrum of contaminants. In the absence of pure water systems, school children could end up drinking allergens, carcinogens or other harmful chemicals.

Sometimes chemicals in the water have the ability to mimic the action of body hormones. When students drink that water, their body biochemistry can not function normally. The students become sick.
Both school authorities and homeowners need to take an interest in what might be in the water. Both school authorities and homeowners have reason to learn about pure water systems. Both groups should feel motivated to search for technology that can guarantee delivery of clean, pure, great-tasting water.

If researchers in both groups take the time to study online literature about water purification, they should soon learn about the benefits of one particular filtration system. That is a system that uses activated carbon filters with ion exchange and micron filtration.

If the proper decision makers then choose to purchase such a system, those recognized decision makers can feel confident that they have made the safest choice.
