English: President Bill Clinton signs the amendments to the Safe Drinking Water Act as children and others watch. On August 6, 1996, President Clinton signed amendments to the Safe Drinking Water Act to implement comprehensive public health protection from the source to the tap. The changes further expanded the scope of SDWA, established a more rational, science-based decision-making process (including risk tradeoffs), and better addressed the compliance challenges that small systems face. The new law also established the Revolving Loan Program, a grant to states for financing infrastructure projects at low interest rates. Other changes include enhancing the Source Water Protection program and expanding grants to tribes, Alaska native villages, and colonias.
