Lead Testing of Drinking Water

Updated Guidance

Revisions to Public Health Law (PHL) §1110, which governs school potable water testing and standards, went into effect December 22, 2022. The key revisions to the law which will require changes to Subpart 67-4 include:

  • The revised action level of lead in drinking water is 5 parts per billion (ppb), reduced from 15 ppb.
  • School buildings deemed “lead-free” are no longer exempt from testing requirements.
  • Should it be necessary to provide water to school occupants following an outlet being taken out of service due to an action level exceedance, it must be provided free of charge.
  • Copies of lead sampling results including laboratory reports and any lead remediation plans must be made available to the public and posted on the school’s website.
  • Compliance testing will occur on a triennial (every 3 years) schedule.
