  • The level, or range of levels, of any contaminant found in local drinking water, as well as the federal health-based standard (maximum contaminant level) for comparison.
  • The likely source of any contaminant in the local drinking water supply.
  • Potential health effects of any contaminant detected in violation of health standards, and an accounting of the system’s actions to restore safe drinking water.
  • The water system’s compliance with other drinking water-related rules.
  • Educational information on nitrate, arsenic, or lead in areas where these contaminants are detected above 50 percent of federal standards.
