What causes discoloration on sinks, tubs, and toilets? If the stains or water are blue-green in color, then most likely, corrosion of copper is occurring within the household plumbing. Stains that are various shades of yellow, tan, brown, black, orange, or red can indicate the presence of metals other than copper. Two other metals that are typically to blame for staining are iron and manganese. While these minerals serve as essential nutrients for your body, they aren’t so kind to plumbing fixtures, appliances and even clothing. Reddish and yellow-tan discoloration is often caused by iron, while black or dark brown discoloration points to manganese. Due to their similarities and their frequent occurrence in tandem, iron and manganese are generally treated in much the same way. Discoloration usually results from the exposure of these metals to oxygen, known as oxidation. In your plumbing, water often has limited exposure to oxygen, keeping any soluble (ferrous) iron or manganese
http://www.governing.com A new report documents what environmental advocates say has been happening for decades: The federal government fails to protect Americans from potentially cancer-causing chemicals. And they have little hope that will change anytime soon. ,4-dioxane is an unregulated industrial solvent often found in shampoos, bubble bath, cosmetic products -- and tap water. Across the U.S., 7 million people in 27 states are drinking water with elevated levels of the chemical that the Environmental Protection Agency classifies as a "likely carcinogen," according to a report published last week by the nonprofit Environmental Working Group (EWG). Despite decades-long concerns about the chemical’s connection to cancer, liver and kidney damage, the EPA does not regulate 1,4-dioxane levels in drinking water. That leaves millions of people exposed, with no knowledge of the elevated cancer risk they could be creating for themselves. According to the EWG, that
You know that water softeners eliminate several headaches around your home—from spotty dishes and stiff laundry to costly appliance repairs. But a common question is whether a softener will also remove important minerals from your water that you and your family need to stay healthy. Happily, this is not a concern for water softener owners, and here’s why: The minerals found in your tap water are in a form that your body can’t properly digest. If you’re looking to add key vitamins and minerals to your diet, it is more important to focus on the food you eat. A well-balanced meal plan will provide the daily dose of nutrients you need to stay healthy. If you’re concerned about your intake, consider adding a multivitamin or supplement. Water softeners are designed to capture and remove specific minerals (magnesium and calcium) from your water. This process gets rid of the home-damaging hardness minerals and leaves minerals like fluoride (which helps prevent tooth decay) intact. Not only
