ssaic Valley Water Commission found elevated levels of lead in drinking water in some homes/buildings. Lead can cause serious health problems, especially for pregnant women and young children."
How Can I know if Lead in Drinking Water Is My Problem?
If you get your tap water from a public water system, they are required by law to send you annually a Consumer Confidence Report (CCR). Your report will tell you which contaminants were above the limit set by the EPA (Environmental Protection Agency) or above the MCL (Maximum Contaminant Level. Look to see if there is lead in your water and how much. They cite the "Level Found" and the "MCL" (Maximum Contaminant Level). For lead, the standard set by the EPA is.015 milligrams per liter. Any water which has more than this amount of lead is not safe. The water company is required to state in the CCR if lead is over the MCL limit and what they are doing to correct it. They are also required to inform the public through newspapers and television that the level of lead is over the level of safety.
If you get your tap water from a private well [link widoczny dla zalogowanych], it is recommended that you have it tested for lead and other pollutants that may make it unsafe to drink as is. You can order a water testing kit and test it yourself, or hire a water testing laboratory in your area to do it for you.
Because much lead pollution actually comes from home plumbing and from the water delivery system, the only way to really know the actual level of lead in you tap water is to test it yourself or have it tested by a laboratory for you. You cannot be sure that the level of lead at your tap is the same as that cited by your Consumer Confidence Report. Your tap water may have picked up additional lead from the town plumbing or from your house plumbing.
How Would I Go About Removing Lead in Drinking Water?
There are several simple precautions you can take to reduce the level of lead in your tap water. For one [link widoczny dla zalogowanych] don't use hot tap water in your cooking since hot water tends to bring more lead out of the plumbing. Secondly, if your water has sat in your pipes without being used for more than 6 hours, let it run until the cold water from outside your house is coming through your tap. This should take 15 to 30 seconds. This will flush out lead that has seeped from your plumbing into the water sitting in your pipes.
There are three kinds of filters that can remove lead in water from your tap water: Distillation, Reverse Osmosis, and Filtration (granular or carbon block). However, you need to check the individual filter that you are considering to not only see if they claim to reduce lead, but to verify that it has been certified by the NSF International as a filter that does indeed effectively reduce lead.
The NSF International has a usefull tool for finding filters that remove lead. You simply check off "lead" and any other contaminants you wish to remove from your tap water and they will give you a list of those filters that have been certified by them to remove those contaminants.
