Is Spring Water Better Than San Diego Tap Water?
Quick Summary: San Diego’s tap water comes from the Colorado River, State Water Project, desalinated seawater, and local sources. While treated to meet EPA standards, it can contain trace contaminants like arsenic, chromium, and disinfection byproducts. Many residents choose spring water from Mount Palomar for its crisp taste, natural minerals, and purity—or opt for reverse osmosis systems for consistent, high-quality water at home. Culligan of San Diego offers both bottled delivery and advanced filtration solutions.
Spring water has become a popular option in San Diego for people looking to avoid the taste and potential byproducts of municipal tap water. Whether you’re prepping for another dry season or simply want a reliable source of cleaner drinking water, spring water offers a natural alternative—often with a crisp taste thanks to its mineral-rich origin.
In San Diego County, locally sourced spring water from the Palomar Mountains. This aquifer-fed source gives residents access to spring water that’s naturally filtered and full of beneficial minerals.
But is it actually better than tap water? Here’s what San Diego residents should consider before making the switch.
What Is Spring Water?
Spring water originates from underground aquifers and flows naturally to the surface due to pressure. It may be collected directly from the springhead or accessed through artesian wells. Unlike treated municipal water, spring water retains natural minerals like calcium and magnesium, which contribute to its fresh taste and potential health benefits.
In San Diego, spring water from Mount Palomar has earned a reputation for quality. Fed by protected mountain aquifers, these springs filter water naturally through layers of rock and soil before being bottled and distributed. The result? A crisp, clean-tasting water that feels like it came straight from nature—because it did.
These regional springs not only provide a refreshing drink but also highlight the geology and natural beauty of the Palomar Mountain Range, a cherished part of San Diego’s inland terrain.
What’s in San Diego Tap Water?
According to the 2024 Water Quality Report from the San Diego County Water Authority, local tap water is a blend of imported sources from the Colorado River and State Water Project, along with local surface water and desalinated water from the Carlsbad Desalination Plant.
Although this water is treated and tested to meet federal and state standards, it still contains trace levels of regulated contaminants. The Environmental Working Group (EWG) lists the following substances found in San Diego’s water supply:
- Haloacetic acids (HAA5)
- Total trihalomethanes (TTHMs)
- Arsenic
- Hexavalent chromium
While these fall within EPA limits, some exceed EWG’s more stringent health-based guidelines. For families with children or immunocompromised individuals, spring water or high-quality filtration systems may offer added protection.
Why San Diego Residents Choose Spring Water
For many in San Diego, choosing spring water isn’t just about what’s in the tap—it’s about the taste, quality, and connection to local nature.
Here’s why spring water is becoming a top choice:
- Better taste: Free of chlorine and chemical additives, spring water tastes fresher and smoother.
- Natural minerals: Spring sources from Mount Palomar contain beneficial minerals like calcium and magnesium.
- No disinfection byproducts: Spring water avoids byproducts like TTHMs and HAA5s that result from chemical treatment.
- Convenience: Local services—including Culligan—offer bottled water delivery right to your door on a custom schedule.
In a city that values wellness, sustainability, and lifestyle quality, spring water checks all the boxes.
Spring Water Alternatives
If bottled spring water isn’t your preferred option, high-performance filtration systems can offer a similarly clean and fresh water experience—straight from your tap.
Reverse osmosis (RO) systems use several stages of filtration—including sediment and carbon filters plus a semipermeable membrane—to remove common contaminants. The result is clean, great-tasting water comparable to most bottled options.
Culligan of San Diego also provides deionized water, which is ultra-purified through both RO and ion exchange to remove nearly all dissolved solids.
These options are great for:
- Eliminating heavy metals and chlorine
- Improving taste, odor, and clarity
- Supporting safe water use for cooking, drinking, and childcare
If you want clean water without single-use plastics or recurring bottled purchases, a home system might be the best fit.
