Yes, the majority of public water systems in Oklahoma meet or exceed federal and state drinking‑water standards. For example, Oklahoma City Utilities Department reported zero drinking‑water violations in 2024.

That said, “meets standards” doesn’t mean zero contaminants. Some systems detect trace levels of substances like PFAS or naturally‑occurring arsenic, chromium, or uranium, particularly in certain aquifers. 

If you’re on a private well, you should test your water regularly since these wells are not regulated by federal standards.  If your business is located in Oklahoma, consider a clean water solution like a Culligan Quench filtered water solution for your guests and employees. 

In Oklahoma, some of the most common water quality concerns include emerging contaminants like PFAS (“forever chemicals”) and naturally occurring elements in groundwater such as arsenic, chromium, selenium, or uranium, which in some wells can exceed drinking-water standards. 

Many areas also have hard water, with high levels of calcium, magnesium, or sulfates, which isn’t usually a health risk but can cause limescale buildup, appliance wear, and changes in taste or odor. Additionally, older infrastructure or private wells can sometimes lead to distribution issues or localized contamination. Regular water testing, using certified filtration systems, and staying informed about local water reports can help ensure safe and clean drinking water for your business.
