The purpose of this document is to describe how the objectives of the federal Clean Water Act and the federal Safe Drinking Water Act statutes are implemented in Colorado. This Guide is divided into two major sections. The first section (Part 1) describes how Colorado protects the quality of its ambient water bodies, and the second section (Part 2) describes how Colorado's Safe Drinking Water Program is primarily focused on ensuring that the water provided by public water systems "at the consumer's tap" is always safe to drink.
