Lead in Drinking Water

glass of waterIn recent months, reports regarding high levels of lead in the drinking water in Flint, Michigan have been in the news.   The City of Antioch wants to reassure you that our customers are protected by a comprehensive water quality and sampling program that ensures the drinking water in Antioch continues to meet or surpass all federal and state drinking water standards for public health and safety.  Lead is a common, naturally occurring metal found throughout the environment. Lead seldom occurs naturally in water supplies like rivers and lakes, and lead is rarely present in water coming from a treatment plant. Lead can get into drinking water when service lines, household pipes, or household fixtures corrode.  The City of Antioch water distribution system does not have any lead service lines, and our source water does not contain lead.  Our corrosion control program helps to limit leaching of lead by preventing the corrosion of household pipes and fixtures. 

Water Quality Testing for Lead

All water systems are required to monitor target homes every three years to determine the level of lead and copper that may leach out of our water lines or their home plumbing systems and faucets. Lead and Copper monitoring, reporting and compliance has been part of our water quality monitoring program since 1992. Participants are chosen based on their homes’ year of construction; homes built before 1986 are more likely to have lead pipes, fixtures or solder. The samples are analyzed by a State-certified laboratory, and the results are reported to the homeowners who collected the samples, and are also summarized in our Annual Water Quality Report.  In 2015, 65 homeowners participated and collected samples for our study; none of the lead levels exceeded the action level set by the EPA.

In addition to the triennial tap sampling for lead, we are required to report other water quality parameters on an annual basis to demonstrate that our corrosion control measures are effective.  This information is also reported to the public in our Annual Water Quality Report.

If you’re concerned about lead in your drinking water, you can take several steps to limit possible exposure:

  • Run your water to flush out lead.  If water hasn’t been used for several hours, run water for 15-30 seconds or until it becomes cold or reaches a steady temperature before using it for drinking or cooking. This flushes lead-containing water from the pipes.
  • Use cold water for cooking and preparing baby formula.
  • Do not boil water to remove lead.
  • Identify and replace plumbing fixtures containing lead.

Despite concerns about drinking water, the U.S. Environmental Protection Agency notes that the greatest exposure to lead is swallowing or breathing in lead paint chips or dust.  For more information on reducing lead exposure around your home and the health effects of lead, visit EPA’s Web site at www.epa.gov/lead.
