Did you know that sodium is naturally present in water sources across the US, and around the world? You can see in the graphic below how a few different cities rate in sodium content. The AHA recommends that no more than 10% of dietary sodium intake should come from drinking water. Their guidelines recommend a maximum of 1500 mg per day for most people, and a maximum of 500 mg per day for those on severely sodium-restricted diets. According to these guidelines, many of us surpass the 10% limit just from drinking city water!
An interesting thing happens, too, when we drink water softened with a traditional salt-type softener. Because salt-type water softeners work by replacing hardness mineral ions with sodium ions through a process called “ion exchange,” the hardness of your water will affect the level of sodium in water. Using the standard calculation of
Sodium added (mg) = liters of water you drink x hardness removed (gpg) x 8 mg/l/gpg**,
you can see that if you live in Phoenix, AZ which has an average water hardness of 18 gpg, you’re adding 144 mg/l of sodium to your diet through softened water alone. Now, add back in the sodium that’s naturally present in your water, and multiply by the amount of water you drink in a day, and it becomes clear how much sodium you’re really drinking. In Phoenix, drinking 2 liters of softened water per day means that you have consumed 520 mg of sodium through your drinking water alone.
Sodium added (mg) = 2 liters of drinking water (18 gpg of hardness x 8 mg/l/gpg + 116 mg/l naturally present sodium)
Sodium added = 520 mg
If you’re on a sodium-restricted diet and drinking salt-softened water in Phoenix, you have not only far surpassed the recommendation of no more than 10% of sodium from water, but you’ve consumed more than your 500 mg maximum for the day! In the map below, you can see the calculated sodium levels for each city when a traditional softener is used to treat the water. If you live in one of these cities, you can multiply this number by the amount of water you drink in a day to see how this might affect your diet. If you’d like help determining how much sodium is in your city’s water, give us a call at 1(877)708.3338. If possible, try to have your city’s water quality report handy.
Many states mandate that salt-type water softeners be installed to bypass the kitchen sink in order to prevent residents from drinking salt-softened water. If this isn’t the case in your home, consider installing a RevitaLife Drinking Water System to remove the added sodium from your drinking water, or finding another source for drinking water. Or, if you’re considering going salt-free, give us a call at 1(877) 708-3338. Our residential specialists will help talk through your water problems, and determine if the EasyWater No-Salt Conditioner will be a great fit for you!
