Fortuna Foothills Water Hardness & Quality Report (2026)

Fortuna Foothills, Arizona is served by Foothills Water and Sewer LLC (Foothills Utilities), headquartered at 10371 S Del Rico, Yuma, AZ 85367. The utility operates the Foothills Water Treatment Plant, which draws its primary surface water supply from Canal A, sourced from the Colorado River. A secondary groundwater source provides backup capacity during emergencies or surface water loss. The utility serves the Yuma County area with 24/7 emergency service available at (928) 783-4421, and publishes annual Consumer Confidence Reports detailing compliance with federal drinking water standards.

The water supply originates in the Colorado River watershed, which flows through a region dominated by Quaternary alluvial deposits and older Tertiary bedrock formations rich in carbonate minerals. The Colorado River picks up dissolved calcium and magnesium as it flows through limestone and other mineral-bearing rock layers along its course. Groundwater in the region similarly reflects this mineralogy, contributing to the characteristically hard water supply typical of southwestern Arizona and the broader Yuma area.

Fortuna Foothills residents experience very hard water, with hardness typically ranging from 18–22 grains per gallon across the Yuma area. Water softening treatment is strongly recommended to protect plumbing fixtures, water heaters, and appliances from scale buildup and premature wear. Residents should expect increased soap consumption and reduced detergent effectiveness without treatment. According to Foothills Utilities' 2024 Consumer Confidence Report, low contamination risk is maintained per a 2003 ADEQ source water assessment; a monitoring violation for DI(2-ethylhexyl) phthalate in 2024 was corrected with no analyte detections above laboratory limits, and all synthetic organic compounds tested were non-detect.
