Drinking Water Regulations

Regulations

The United States Environmental Protection Agency (EPA) is authorized by the federal government to set drinking standards to protect the drinking water supplies. As a result, the Safe Drinking Water Act (SDWA) was established in 1974. This law focuses on all waters actually or potentially designated for drinking water use, whether from ground water sources or surface water sources.

The SDWA authorizes the EPA to establish minimum standards to protect tap water and requires all owners and operators of public water systems to comply with these National Primary Drinking Water Standards (health-related) standards. In 1996, amendments to the SDWA require that EPA consider a detailed risk and cost assessment, and best available peer-reviewed science, when developing these standards. State governments, which can be approved to implement these rules for EPA, may choose to enforce standards that are more strict than the SDWA requires. In addition, both EPA and States encourage attainment of National Secondary Drinking Water Standards (nonenforceable, aesthetic and nuisance-related standards).

In Arizona, the Arizona Department of Environmental Quality (ADEQ) has authority (or “primacy”) for enforcing the drinking water rules and programs of the SDWA. Under the ADEQ primacy agreement, federal drinking water rules are incorporated by reference into the Arizona Administrative Code where they are enforceable by the State.

Global Water’s Environmental Resources Department (ERD) is responsible for ensuring the drinking water delivered to our customers meets all State and Federal drinking water standards. The ERD is also responsible for long term planning of ensuring future water resources are available and will meet health standards of future regulation.

By July 1st of every year, Global Water is required to send each customer an Annual Water Quality Report (also known as a Consumer Confidence Report). The information contained in this report includes results from samples obtained from the previous year. Even though numerous samples are taken, the report will only contain information on the samples that had detected concentration levels of a contaminant.
