Which of the following describes the Consumer Confidence Report (CCR)?

The Consumer Confidence Report (CCR) is designed to provide consumers with essential information regarding the quality of their drinking water. This report summarizes various water quality data, including details about any contaminants that may be present in the water supply, and compares these levels to established health standards. It aims to empower consumers by informing them about what is in their water and how it measures up against safety benchmarks. The CCR is required to be distributed annually by public water systems and is an important tool for transparency and consumer awareness regarding water safety and quality.

The other options do not accurately reflect the purpose of the CCR. Infrastructure improvements, the cost of water services, and customer complaints pertain to different aspects of water utility management and consumer interaction but are not the primary focus of the CCR itself.
