Service Area Demographics

💧 Where Does Your Water Come From?
Slick's water is pumped from underground aquifers. Groundwater is naturally filtered through rock and soil, but it can be vulnerable to PFAS contamination, nitrates from agriculture, and industrial chemicals that seep into the water table.
About 2% of homes in Creek County, Oklahoma rely on private wells rather than public water systems. Private well owners are responsible for their own water testing and treatment.
