What Makes San Diego Country Estates's Water Unique?
Local geology and source profile
San Diego Country Estates, California, in San Diego County — a San Diego County unincorporated community adjacent to Ramona and Lakeside in the east San Diego County backcountry — receives its water from the Ramona Municipal Water District, drawing from the San Diego aqueduct imported supply and local wells through the east San Diego County distribution.
The hard 174.5 mg/L hardness and TDS of 528 mg/L reflect the San Diego County supply's hard blended backcountry character — the Cretaceous Peninsular Ranges Tonalite and Quaternary Santa Maria Valley alluvium are insoluble-calcareous formations in the southern California coast range; the local well component at Ramona concentrates higher hardness and TDS relative to the imported Colorado River/State Water Project aqueduct supply (compare Ramona CA: 170/518 in San Diego County comparable; Lakeside CA: 178/538 in San Diego County comparable; San Diego Country Estates consistent hard from the same San Diego County MWD import/well blended Cretaceous supply). The San Diego County supply — Cretaceous Peninsular Ranges Tonalite (insoluble — primary dilutant), Quaternary Santa Maria Valley alluvium (calcareous — primary hardness contributor), and Quaternary southern California coastal alluvium (calcareous — TDS contributor).
At 174.5 mg/L with TDS 528, San Diego Country Estates' water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 6.9 ppt warrants a certified drinking water filter. Review the Ramona Municipal Water District's annual water quality report.
