Tap water from a municipal system is probably the safest commodity that you purchase, much safer than the food supply where every year there are many reports of consumer deaths and sickness.
All municipalities have to preform checks as to the quality of the product, Typically a Chlorine residual is checked daily or more often for larger systems. Bacteria tests and chlorine resuidals are checked at strategic spots in the system where the water may not be used as rapidly to ensure that it is suitable for consumption.
Periodically other tests for lead copper and numerous potential organic contaminants are required for all systems. Each year the municipal water supplier is required to send to each customer the results of these tests and explain any deviations. The allowable limits for these potential contaminents are derived by the EPA based on the premise that a consumer drinking 2 liters of water per day for 70 years would have a 1 in 1,000,000 chance of having some ill effect from that chemical contaminent. Bacteria and viruses and such are always set at 0,which is why keeping a Chlorine residual is so effective.
The food you buy and the water you buy in the plastic bottle by the case at a store has little or no regulations of this type and the water can sit in the plastic bottle for months in the back seat of your vehicle leaching all of the plasticizers out of the bottle which may explain why it tastes funny sometimes.
