Water described as “Hard” is water that has a high concentration of dissolved minerals, specifically calcium and magnesium. Hard water is not a health risk, but a COSTLY nuisance. Build-up of rock deposits will ruin home fixtures, clothes, pipes, appliances, and hot water heaters. Along with the destruction of these every day household items cost in soaps, and cleaners will increase as hard water makes cleaners less efficient.
Sulfur in your water is easily recognized by it’s offensive odor. Hydrogen sulfide gas causes the “rotten-egg” or sulfur smell in your water. Hydrogen sulfide in water causes no known health effects. However, high concentration s do change the taste. Sulfur-related bacteria can thrive in oxygen-starved environments of deep wells.
Tannins are found in water that has passed through a large quantity of decaying vegetation. Tannins can cause yellow water, yellow staining on fabrics and fixtures, and iron.Common signs of Tannins are:
Lead can still be found in some metal water taps, interior water pipes, or pipes connecting a house to the water main pipe from the street. Lead found in tap water usually comes from corrosion of older fixtures or from the solder that connects pipes. When water sits in the leaded pipes for several hours, lead can leach into the water supply.• Source CDC
Naturally occurring unstable radio-active elements are found in all rocks, soil, and water. The common long-lived radioactive elements, uranium, and thorium, decay slowly to produce other radioactive elements, such as radium, which also undergo radioactive decay. Radium cannot be seen, tasted, or smelled. Water must be professionally tested to find out if your well has radium.
Nitrates can occur naturally in surface and ground water at a level that does not generally cause health problems. High levels of nitrates in well water often result from improper well construction, well location, overuse of fertilizers, septic systems, animal feedlots, industrial waste, and food processing waste. Wells may be more vulnerable to such contamination after flooding, particularly if the wells are shallow, have been dug or bored, or have been submerged by floodwater for long periods of time.•Source CDC
Arsenic is a naturally occurring chemical element that has different harmful health effects depending on how much arsenic gets into your body and your sensitivity to it.As groundwater levels decrease, arsenic levels have been know to increase. “We are seeing illness association with lower and lower arsenic exposure levels,” said Joseph Grazino, professor of Environmental Health Science at the Mailman School of Public Health at Columbia University.
Chromium 6, the cancer causing chemical best know from the movie Erin Brockovich, has been found at higher than recommended levels in tap water supplying two-thirds of all Americans, according to a report from the Environmental Working Group. Chromium-6 occurs naturally in the environment, but high quantities are also produced by industrial projects. Pollution can occur when these industrial sites fail to follow proper waste disposal methods.
