Every jurisdiction sets standards for when water is safe to drink. The numbers vary based on the safety margin the regulators and used feel comfort in using. This allows some "Ooops!" event in the water supply without harming anyone.
The base numbers for contaminants are based on "No observed effects levels" identified by testing various concentration's impacts on animals and extrapolating these impacts to humans. Sometimes the levels are based on taste, odour or appearance not health impacts.
