Q: What about lead in sources other than drinking water? A: As mentioned above, drinking water is estimated to contribute only 10 to 20 percent of the total lead exposure in young children. Ask your local health department or call EPA for more information on other sources of exposure to lead. A few general precautions can help prevent contact with lead in and around your home: - Avoid removing paint in the home unless you are sure it contains no lead. Lead paint should only be removed by someone who knows how to protect you from lead paint dust. However, by washing floors, window sills, carpets, upholstery and any objects children put in their mouths, you can get rid of this source of lead.
- Make sure children wash their hands after playing outside in the dirt or snow.
- Never store food in open cans, Keep it in glass plastic or stainless steel containers. Use glazed pottery only for display if you don't know whether it contains lead.
- If you work around lead, don't bring it home. Shower and change clothes at work and wash your work clothes separately.
Q: Aren't there a lot of types of treatment devices that would work? A: There are many devices which are certified for effective lead reduction, but devices that are not designed to remove lead will not work. It is suggested that you follow the recommendations below before purchasing any device: - Avoid being misled by false claims and scare tactics. Be wary of "free" water testing that is provided by the salesperson to determine your water quality; many tests are inaccurate or misleading. Research the reputation and legitimacy of the company or sales representative.
- Avoid signing contracts or binding agreements for "onetime offers" or for those that place a lien on your home. Be very careful about giving credit card information over the phone. Check into any offers that involve prizes or sweepstakes winnings.
- As suggested above, verify the claims of manufacturers by contacting the NSF International or the Water Quality Association.
Q: What is the government doing about the problem of lead in household water? A: There are two major governmental actions to reduce your exposure to lead: - Under the authority of the Safe Drinking Water Act, EPA set the action level for lead in drinking water at 15 ppb. This means utilities must ensure that water from the customer's tap does not exceed this level in at least 90 percent of the homes sampled. If water from the tap does exceed this limit, then the utility must take certain steps to correct the problem. Utilities must also notify citizens of all violations of the standard.
- In June 1986, President Reagan signed amendments to the Safe Drinking Water Act. These amendments require the use of "lead-free" pipe, solder, and flux in the installation or repair of any public water system, or any plumbing in a residential or non-residential facility connected to a public water system.
Under the provisions of these amendments, solders and flux will be considered "lead-free" when they contain not more than 0.2 percent lead. (In the past, solder normally contained about 50 percent lead.) Pipes and fittings will be considered "lead-free" when they contain not more than 8.0 percent lead. These requirements went into effect in June 1986. The law gave state governments until June 1988 to implement and enforce these new limitations. Although the states have banned all use of lead materials in drinking water systems, such bans do not eliminate lead contamination within existing plumbing. Also, in enforcing the ban, some states have continued to find illegally used lead solder in new plumbing installations. While responsible plumbers always observe the ban, this suggests that some plumbing installations or repairs using lead solder may be escaping detection by the limited number of enforcement personnel. (flushed sample will indicate the effectiveness of flushing the tap before using the water.)
