There is no such thing as “pure” water, at least not so far as science has discovered. According to Green Water Technologies, even water filtered through the most advanced processes contains minerals and other miniscule particles. Some of these are harmful if ingested, others enhance the health benefits and taste of water. The source of the former are addressed in the following Q&A.
Q: Where does water pollution come from?
Green Water Technologies: Water pollution stems from both natural sources and from human activities. Heavy metals in underground soil, nitrates, and microorganisms are examples of natural contaminants. Runoff from farms, household waste, and landfills are all human-derived pollutants.
Q: How do fertilizers and other manmade poisons wind up in drinking water?
Green Water Technologies: Water is always moving. That means that the rainwater that grows your flowers in May might wind up in your cup by September. As water journeys from the sky to the ground, it picks up chemicals, debris, and even bacteria from agricultural operations along the way. Most municipal water systems filter the majority of these undesirable intruders out, but people with well water are left at the mercy of the surrounding area.
Q: Is lead a problem in drinking water?
Green Water Technologies: Water in itself usually contains negligible amounts of lead. However, lead poisoning is a concern in older homes where copper and lead pipes may have corroded. Lead poisoning can cause developmental delays in children as well as kidney problems for adults.
Q: Which is safer: natural or manmade contaminants?
Green Water Technologies: Neither! Industrial waste can cause just as many health problems as natural bacteria. The best way to ensure that a home’s drinking water is clear of potentially harmful additives is to filter before it is released for consumption. Swapping older pipes with new, less harmful, materials will also help.
