Lead

Lead is a highly toxic metal used for many years in products in and around homes. Lead‘s adverse health effects range from behavioral problems and learning disabilities to seizures and death. Because their bodies are growing quickly, children age 6 and under are at greatest risk. Primary sources of lead exposure for children are deteriorating lead-based paint, lead-contaminated dust, and lead-contaminated residential soil. Lead might be present in any home built up until the 1940s. Rarely found in source water, lead can enter tap water through corrosion of plumbing materials. Homes built before 1986 are more likely to have lead pipes, joints, and solder. New homes are also at risk: even legally “lead-free“ pipes can contain up to 8 percent lead and leave significant amounts of lead in the water for the first several months after installation. Since the 1980s, EPA and its federal partners have banned or limited lead used in consumer products, including residential paint. Federal regulations limiting the amount of lead in paint sold for residential use started in 1978. If your property was built before 1978 or you are considering remodeling, renovating, or repair, you may wish to think about lead inspection. Water quality can be compromised by such other trace elements as iron, excess acidity, manganese, calcium, magnesium, mineral salts, hydrogen sulphide, selenium, chromium, arsenic, mercury, and cadmium.
