Bad taste

The “rotten egg” odor, “swimming pool” smell and metallic taste are just some of the descriptions frequently reported by consumers.  Whether natural or man-made elements are added to your drinking water, the result may be an offensive taste and odor.
In many cities, municipal tap water simply tastes bad because of the treatment process used, the pipes it travels through, and the source of the water. Running the water may dissipate the taste, but rarely the smell. The most common remedy is a tap filtration system to alter the taste and a water conditioner to eliminate the smell.
Two common sources of bad taste are Sulfur and Chlorine. Sulfur can be naturally occurring in many areas, and sometimes peaks during certain times of the year. Sulfur accounts for the rotten egg smell that tap water can acquire, along with a bitter taste. Chlorine comes from chlorination, the most universally used and cheapest water disinfectant method. Sometimes excess amounts are used and you end up with a high concentration of chlorine in your pipes
Another common source of odd smells and tastes in tap water is metals from the pipes used to carry your tap water. Copper, iron, and lead have all been found in tap water, and lend unique smells and tastes. Usually copper and iron appear in low concentrations and will not be harmful, although they can discolor your water. Rusty brown water is a result of high amounts of iron, and can indicate that your pipes may need to be replaced. Lead is a more serious concern, because it can have negative impacts on human health in even small amounts; if you suspect that your water contains lead due to contaminated pipes, get it tested immediately and refrain from drinking it.
