Water quality refers to the chemical, physical and biological characteristics of water. It is a measure of the condition of water relative to the requirements of one or more biotic species and or to any human need or purpose. The most common standards used to assess water quality relate to health of ecosystems, safety of human contact and drinking water.
Water is the universal solvent. This means it absorbs a little of almost everything it makes contact with. Unfortunately, this results in several issues that can be detrimental to your home and your health.
Hard Water is the result of water absorbing calcium and magnesium from limestone, chalk or marble deposits. Hard water is not a health concern, and is very common. Indications of hard water include: white marks; stains and scale on sinks, baths, toilet bowls and around the base of taps; blocked showerheads, and scale deposits on kettles.
Iron (causing Bad Taste & Odor, Rust Stains)
Iron is one of the most common contaminants in well water. Iron is not a health concern at levels encountered in normal drinking water. Higher concentrations of iron can cause an objectionable metallic taste and orange or rust-colored staining of sinks, toilet, bathtubs and clothes.
Water with a low pH level (potential of Hydrogen) is considered acid water. Water with a low pH can cause damage to sinks, faucets, hot water tanks, drainage and supply lines. These problems can cause extensive repair costs or replacement. Pitting on plumbing fixtures usually indicates low pH.
Sulfur (causing Bad Taste & Odor)
Sulfur is a colorless gas which causes damage to plumbing and gives off an offensive, "rotten egg" odor.
When Chlorine mixes with organics in water, trihalomethanes (THMs) are formed. THMs are reportedly cancer-causing agents. Substantial amounts of chlorine are not appropriate for inside home and drinking use.
