Lead in Home Plumbing If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing.We are responsible for providing high-quality drinking water, but cannot control the variety of materials used in plumbing components.When your water has been sitting for several hours,you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for """ k drinkingor cooking. Ifyou are concerned about lead inyour water,you maywish to haveyour water A ', g �". tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at www.epa.gov/lead. t What Causes the Pink Stain on Bathroom Fixtures? The reddish-pink color frequently noted in bathrooms on shower stalls, tubs, tile, toilets, sinks, toothbrush holders, and on pets' water bowls is caused by the growth of the bacterium Serratia marcesens. Serratia is commonly isolated from soil,water, plants, insects, and vertebrates (including humans). The bacteria can be introduced into the house through any of the above mentioned sources. The bathroom provides a perfect environment (moist and warm) for bacteria to thrive. The best solution to this problem is to continually clean and dry the involved surfaces to keep them free from bacteria. Chlorine-based compounds work best, but keep in mind that abrasive cleaners may scratch fixtures, making them more susceptible to bacterial growth. Chlorine bleach can be used periodically to disinfect the toilet and help to eliminate the occurrence of the pink residue. Keeping bathtubs and sinks wiped down using a solution that contains chlorine will also help to minimize its occurrence. Serratia will not survive in chlorinated drinking water. Substances That Could Be in Water Community Water Fluoridation To ensure that tap water is safe to drink, the U.S. EPA The safety and benefits of fluoride are well documented. prescribes regulations limiting the amount of certain For over 70 years, U.S. citizens have benefited from contaminants in water provided by public water systems. drinking water containing fluoride, leading to better U.S. Food and Drug Administration regulations establish dental health.

Still, tooth decay remains The presence of these contaminants does not necessarily one of the most common chronic diseases of childhood. indicate that the water poses a health risk. Community water fluoridation has been identified as The sources of drinking water(both tap water and bottled the most cost-effective method of delivering fluoride water) include rivers, lakes, streams, ponds, reservoirs, to all members of the community, regardless of age, springs, and wells. As water travels over the surface of educational attainment, or income level. the land or through the ground, it dissolves naturally Nearly all water contains some fluoride, but usually not occurring minerals,in some cases,radioactive material,and enough to help prevent tooth decay or cavities. Public substances resulting from the presence of animals or from water systems can add the right amount of fluoride to the human activity. Substances that may be present in source water include: local drinking water to prevent tooth decay. Community water fluoridation is recommended by Microbial Contaminants, such as viruses and bacteria, nearly all public health,medical,and dental organizations which may come from sewage treatment plants, septic in the U.S. Because of its contribution to systems,agricultural livestock operations,or wildlife; the dramatic decline in tooth decay, Inorganic Contaminants, such as salts and metals, which the Centers for Disease Control can be naturally occurring or may result from urban storm- and Prevention (CDC) named water runoff,industrial or domestic wastewater discharges, community water oil androduction,mining,or farming; fluoridation one of the �P g g 1 � greatest public health Pesticides and Herbicides,which may come from a variety achievements of the • of sources such as agriculture, urban storm-water runoff, 20th century.

Hotline at(800)426-4791. 41 41 Tap vs. Bottled hanks in part to aggressive marketing,the bottled water industry has successfully convinced us all that water purchased in bottles is a healthier alternative to tap water. However, according to a four-year study conducted by the Natural Resources Defense Council, bottled water is not necessarily cleaner or safer than most tap water. In fact,about 25 percent of bottled water is actually just bottled tap water (40 percent according to government estimates). The Food and Drug Administration is responsible for regulating bottled water,but these rules allow for less rigorous testing and purity standards than those required by the U.S. EPA for community tap water.For instance,the high mineral content of some bottled waters makes them unsuitable for babies and young children.Further,the FDA completely exempts bottled water that's packaged and sold within the same state,which accounts for about 70 percent of all bottled water sold in the United States. People spend 10,000 times more per gallon for bottled water than they typically do for tap water. If you get your recommended eight glasses a day from bottled water, you could spend up to $1,400 annually. The same amount of tap water would cost about 49 cents. Even if you installed a filter device on your tap, your annual expenditure would be far less than what you would pay for bottled water.

Water Conservation Tip Top Tap ou can play a role in conserving water and The most common signs that your faucet or sink is affecting the 1 saving yourself money in the process by quality of your drinking water are discolored water, sink or becoming conscious of the amount of water faucet stains, a buildup of particles, unusual odors or tastes, and a your household is using and by looking for reduced flow of water.

Clean these fixtures with vinegar or use water softening leaks. Simply turn off all taps and water to reduce the calcium carbonate levels for the hot water system. using appliances. Then check the meter after 15 minutes. If it moved, you have a Water Filtration/Treatment Devices leak. A smell of rotten eggs can be a sign of bacteria on the filters or in the treatment system.The system can also become clogged over time,so regular filter replacement is important.
