What happens if a Noncommunity Public Water Supply System gets a “ bad ” water sample result?
If any of the samples collected from a noncommunity public water supply system show the presence of a contaminant above its health-based standard (called a maximum contaminant level or MCL), MDH or the local health department will work with the system in resolving the contamination. Additional samples may be required to confirm the presence of the contaminant. If contamination is confirmed, the system is required to notify its users of the problem and it must take steps to correct the problem. Corrective actions may include repairs to the water system, disinfection of the water system, installation of treatment, or drilling a new well. Go to > top.
