How is 'Feasible' defined in the context of the Safe Drinking Water Act?

In the context of the Safe Drinking Water Act, 'feasible' refers primarily to the best achievable level of water treatment technology that can be implemented to ensure safe drinking water. This definition emphasizes the importance of utilizing available technology to minimize contaminants and improve water quality to the highest standard currently achievable.

The phrase 'best achievable' highlights a commitment to continually advancing and adapting technology in water treatment processes. This means that water systems must assess the technologies available for treatment and select those that will yield the best outcomes with respect to public health and safety.

While cost considerations, public satisfaction, and political agreements can influence decisions made under the Safe Drinking Water Act, they are not primary factors in establishing what is 'feasible' in terms of treatment technology. Ensuring that treatments comply with the highest achievable levels is aimed directly at protecting public health, which is the core mission of the Act.
