  • A description of the violation that occurred, including the contaminant(s) of concern, and  the contaminant level(s);
  • When the violation or situation occurred;
  • The potential health effects (including standard required language);
  • The population at risk, including subpopulations vulnerable if exposed to the contaminant in their drinking water;
  • Whether alternate water supplies need to be used;
  • What the water system is doing to correct the problem;
  • Actions consumers can take;
  • When the system expects a resolution to the problem;
  • How to contact the water system for more information; and
  • Language encouraging broader distribution of the notice.
