How does Well Water Compare to GRU or City Water?

Most well owners have been asked, how does your water compare to GRU/city water? The answer comes down to your equipment. With well water systems you can have precise control of every aspect of your water, with the right utilization of softeners, chlorinators and other water conditioners.

GRU shares information regarding their specific water chemistry. The hardness is approximately 140mg/L as CaCO3 (8.2 grains/gal). Water hardness is the amount of dissolved calcium and magnesium in the water. "Hard" water is high in dissolved minerals, both calcium and magnesium. In a well system a water softener, as you might guess, removes the calcium and magnesium.

GRU's pH is 8.6. pH is a value defining the acidity or alkalinity of a liquid on a scale on which 7 is considered 'neutral.' Lower values are more acid, and higher values more alkaline. Well water in this area comes from the Florida aquifer, as does GRU's, and the pH of that is also around 8.6. Most well water in this area has comparable pH, and GRU's water is the same in this respect.

Sulfate levels are 97.4 mg/L, Chloride is 26.3 mg/L, and Ammonia is 0.24 mg/L. These elements, like sulfer and chlorine, are the main chemical culprits/components addressed by water conditioning systems. If your water is smelly you likely have an issue with sulfate in your water. The chloride values can be related to the amount of chlorine used by GRU's sanitization process, but chloride (like the sulfate and ammonia) is a naturally occurring element in water.
