What year did the enforceable standards for new contaminants take effect?

The enforceable standards for new contaminants took effect in 2002 as part of the interim final rule issued under the Safe Drinking Water Act (SDWA). This legislation established national primary drinking water regulations to ensure safe drinking water and to oversee contaminants that had not previously been regulated. The year 2002 marked a significant step in advancing public health protections by incorporating standards for new contaminants that were identified as posing risks to human health.

These standards are crucial as they set the maximum allowable levels of certain contaminants in drinking water, which helps safeguard the quality and safety of water supplies. Understanding the timeline of these regulations is important for water operators, as it helps them comply with the necessary standards and ensure that their water systems provide safe drinking water according to national guidelines.
