Service Area Demographics
The Deer Creek serves a community with a median household income of $93,282 and an estimated 526 residents across its service area. Approximately 86% of housing stock was built before 1986, which increases the likelihood of lead service lines and older plumbing.
Environmental Justice Note: 32% of the population in this service area is classified as disadvantaged under EPA's EJScreen criteria. Communities with higher disadvantaged populations often face disproportionate environmental and health burdens, including aging water infrastructure and limited resources for remediation.
💧 Where Does Your Water Come From?
Deer Creek'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 4% of homes in Grant County, Oklahoma rely on private wells rather than public water systems. Private well owners are responsible for their own water testing and treatment.
