Until the lead source is eliminated, you should take the following steps any time you wish to use tap water for drinking or cooking, especially when the water has been off and sitting in the pipes for more than 6 hours.Please note that additional flushing is necessary: c.High levels of lead in tap water can cause health effects if the lead in the water enters the bloodstream and causes an elevated blood lead level.Most studies show that exposure to lead-contaminated water alone would not be likely to elevate blood lead levels in most adults, even exposure to water with a lead content close to the EPA action level for lead of 15 parts per billion (ppb).
For homes served by public water systems, data on lead in tap water may be available on the Internet from your local water authority.
You should begin by asking your water authority these questions: 1.
Does my water have lead in it above EPA’s action level of 15 parts per billion (ppb)? Does the service pipe at the street (header pipe) have lead in it? It determines which of the next two actions (A or B) you should follow to protect your household’s health.
If your water provider does not post this information, you should call and find out.
