If a water sample exceeds the EPA action level, what interim recommendation may be given to residents?

When a water sample exceeds the EPA action level, one of the recommended interim actions is to flush taps prior to each use. Flushing taps helps to remove any lead or contaminants that may have leached into the water supply from pipes or fixtures, especially when water has been sitting for extended periods. This action is important because lead exposure can pose serious health risks, particularly to children and pregnant women. By flushing the taps, residents can ensure that they are getting fresher water that is less likely to contain elevated levels of lead that may have accumulated in the pipes.

While boiling water can kill bacteria and pathogens, it does not remove lead and can create a false sense of safety. Installing a well is not a practical interim solution for most residents, and directing the water company to change the supply is a more complex process that may not address immediate concerns. Therefore, flushing taps is the most actionable advice for residents to minimize their exposure to lead in drinking water while solutions are being sought.
