What Makes Goleta's Water Unique?
Local geology and source profile
Goleta, California, in Santa Barbara County — a major south Santa Barbara County university city (Goleta is a significant Santa Barbara County city adjacent to the University of California, Santa Barbara — UCSB is one of the most distinguished public research universities in the University of California system, particularly known for its materials science, chemistry, and marine biology programs; Goleta incorporated in 2002 as an independent city after decades as an unincorporated community adjacent to UCSB), a diverse Santa Barbara County community with a significant student, technology, and aerospace engineering population (Goleta is home of the Santa Barbara Airport and significant aerospace and technology industry development — Raytheon Vision Systems and other defense contractors have major facilities in Goleta), home of Girsh Park (a major recreational complex in Goleta), and a community with a strong UCSB connection — draws its municipal water supply via the Goleta Water District. Water hardness in Goleta measures 160 mg/L — classified as hard.
Goleta's hard supply reflects the south Santa Barbara County Santa Ynez Valley watershed's calcareous-moderate geology. The Goleta Water District draws from the Cachuma Reservoir (Santa Ynez River watershed) — draining the Miocene Monterey Formation (calcareous-moderate shale) and Santa Ynez Mountains limestone — producing the hard 160 mg/L.
At 160 mg/L, Goleta residents face regular hard water challenges. Monthly descaling is recommended. Goleta Water District consistently delivers water meeting all California SWRCB and EPA Safe Drinking Water Act requirements.
Geology & Source: Import supply from the Cachuma Reservoir (Santa Ynez River) via the Goleta Water District — the Santa Barbara County south California Santa Barbara coast Goleta corridor (Miocene calcareous-moderate Monterey Formation and Santa Ynez Mountains limestone — the calcareous-moderate south Santa Barbara County coastal supply; effective treatment); hard supply at 160 mg/L in Santa Barbara County.
