MINERAL HOT SPRINGS in SONOMA

Fairmont Spa is situated atop an ancient mineral hot spring, where wellness seekers have been drawn to Sonoma’s Boyes Hot Springs region for centuries. Rich in more than 27 naturally occurring minerals, these geothermal waters were shaped over millions of years by ancient volcanic activity and geological fault lines, creating an underground network that heats and mineralizes the water. The result is a distinctive source of mineral-rich springs steeped in history and celebrated for their restorative properties. The six pools at Fairmont Sonoma Mission Inn & Spa are filled with these naturally-derived waters, allowing guests to experience a truly unique wellness offering.

Mineral Content

The following naturally occurring minerals are present in detectable quantities in the mineral water that fill all of our pools at Fairmont Sonoma Mission Inn & Spa. We invite you to be Nourished by Nature.

 

  • Aluminum
  • Boron 
  • Bromide 
  • Calcium: Functions in the body include, structural bone and tooth growth, blood clotting, muscle contraction, nerve transmission, cell membrane permeability, and is a catalyst in many reactions 
  • Iron: Oxygen transport (hemoglobin); Activates Vitamin A: Antibody production, DNA: RNA and collagen synthesis; drug detoxification; regulates blood fats; boost immune system
  • Magnesium: Catalyst in many reactions, part of bone, nerve transmissions, muscle relaxation; ATP production; tooth enamel; cold adaptation. 
  • Manganese: Skeletal and connective tissue synthesis; synergy release; fatty acids; cholesterol; DNA, RNA; Urea synthesis; mobilizes fats from the Liver. 
  • Potassium: Acid base and fluid balance; nerve transmission; muscle relaxation; insulin release; catalyst; glycogen and protein synthesis; primary positive electrolyte inside cells. 
  • Chloride: Allows blood to carry Oxygen and Carbon Dioxide; growth of bone and connective tissue; key electrolyte. 
  • Iodine: Regulates body energy usage through Thyroxin. 
  • Zinc: DNA and protein synthesis; fertility; skin growth; healing; protein digestion; Carbon Dioxide removal; disease resistance; processing alcohol.
  • Fluoride: Aids the hardening and stability of Calcium Salts (bones and teeth) 
  • Sulfate: Offers energy transfer (coA, Biotin); Blood clotting, detoxifier, collagen for hair, nails and skin synthesis 
  • Nitrate 
  • Antimony 
  • Copper: Works with Iron in the red blood cell formation: energy release: nerve wrapping: Collagen, Elastin and Melanin synthesis (tanning pigment) 
  • Molybdenum: Mobilizes Iron from Liver stones; Uric acid excretion; works with fluoride. 
  • Bicarbonate 
  • Carbonate 
  • Silicate: Stimulates growth; Collagen synthesis, bone calcification. 
  • Nickel: DNA and RNA synthesis; enhances Iron use. 
  • Phosphate: Captures energy (ATP); absorption and transformation of nutrients; DNA and RNA synthesis. 
  • Chromium: Works with Insulin to allow Glucose into cells; indirectly affects levels of fat in the blood.
