I’ve said it before, and I’m sure I’ll say it again someday, but producing and distributing safe drinking water to Eden Prairie homes and businesses is one of the most important functions of the City. 60,000 people could not live together in 36 square miles without safe water and dependable sewer services. Without either one, the public health challenges of this kind of population density would make this a tough place to live.
We get occasional questions about our water supply throughout the year. During the summer, the most common question has to do with water supply, as in “Why can’t you just make more water?”. The residents asking that questions don’t usually like our answer because their lawn is getting crunchy and they want to put more water on it. The answer has to do with our access to water in the aquifer, the daily treatment capacity of our Water Treatment Plant; and our concern that water towers remain sufficiently filled just in case there is a fire and we need it for that.
A couple of weeks ago our new Utilities Manager, Rick Wahlen, fielded a question about the sodium levels in our water. We are one of the few cities in the Twin Cities metro area that softens our public water supply. It’s a fair question. It’s a question I had not heard the answer to so I thought I’d share Rick’s answer with you:
Our typical sodium content based upon our routine Minnesota Department of Health (MDH) metals assay is between 6 and 8 parts per million.
Assuming a person drinks 10 glasses of water per day at 8 ounces per glass, he would consume less than 0.001 oz. of sodium each day.
According to the below website:
http://www.mindfully.org/Water/2004/Glass-Of-Water17feb04.htm
The average man takes in 7.8 grams to 11.8 grams of salt each day, and the average woman consumes 5.8 to 7.8 grams, which are not very accurate numbers because these estimates are based on salt contained within an average comparison of the typical daily food intake, and do not include salt added at the table.
How much salt should people eat? For healthy adults 19 to 50, the desirable level is 3.8 grams of salt (about two-thirds of a teaspoon, or 1,500 milligrams of sodium) daily, the amount needed to replace what is lost in sweat.
For an upper limit, the panel set 5.8 grams of salt a day (a little more than one teaspoon), but noted that this was not a desirable amount. The panel said that more than 95 percent of American men and 75 percent of American women ages 31 to 50 regularly consumed salt in excess of the upper limit established by the group.
Doing some units conversions, the 1500 mg of sodium equates to approximately 0.134 oz. of sodium, which is about 1,000 times the quantity contained in the 10 glasses of tap water we should drink each day.
Drinking water flushes sodium out of the body and actually keeps a person’s sodium content from getting too high. Ten 8 oz. glasses of water contain about 1/1000th the recommended daily allowance of sodium and would help the body eliminate excess sodium consumed in food, especially for those processed food consumers who like chips and fries.
Drink it up. Our water is good for you. And you can still buy about 1,000 gallons from us for about a $1.00. What a deal!
