What Makes Buena Park's Water Unique?
Local geology and source profile
Buena Park, California, in north Orange County (home of Knott's Berry Farm) adjacent to Anaheim, draws its municipal water supply through the City of Buena Park Public Works Water Division, sourcing from the Orange County Water District (OCWD) groundwater basin — pumping from the Main San Gabriel Basin and Orange County Basin alluvial aquifer — and from Metropolitan Water District (MWD) imported water delivered via the Municipal Water District of Orange County (MWDOC). Water hardness in Buena Park measures 115 mg/L — classified as moderately hard.
Buena Park's moderate hardness reflects the Orange County Water District's north county groundwater character in the Buena Park zone. The OCWD basin in north Orange County is recharged by the San Gabriel River spreading operations at Anaheim Lake and the Groundwater Replenishment System (GWRS) (advanced purified recycled water recharge) near Anaheim. The San Gabriel River source water contributes soft mountain runoff from the San Gabriel Mountains granodiorite, but the deep alluvial basin in north Orange County shows somewhat higher hardness than the western Orange County zone (Westminster: 78 mg/L) — possibly reflecting different aquifer depth zones tapped and the Colorado River–SWP MWD import blend fraction.
With hardness at 115 mg/L, Buena Park residents encounter moderate scale accumulation. Faucet aerators and showerheads develop deposits after several months — monthly cleaning with citric acid solution is practical maintenance. Dishwashers produce cleaner glassware with rinse-aid. City of Buena Park Public Works and OCWD consistently deliver water meeting all California SWRCB and EPA Safe Drinking Water Act requirements.
Geology & Source: Mixed supply from Orange County Water District (OCWD) groundwater basin and Metropolitan Water District (MWD) imports via the City of Buena Park Public Works Water Division — the Main San Gabriel–Orange County Basin alluvial aquifer; moderately hard supply at 115 mg/L in north Orange County near Disneyland.
