Post # 137 - Dasani Purified, Mineralized Rouge River Water - 4/4/2010

Dear Dasani,

I run marathons. Sometimes distance training involves temps well into the 90’s. When I’m hydrating, I’d like to know in my heart of hearts that I’m not drinking something that could in fact further dehydrate me. I’d like something that doesn’t have additives which may swell my hands, tongue, and face.

What gives? What’s with adding table salt, potassium chloride, and magnesium sulfate to your water? I’ve read where your additives can cause dehydration and kidney failure in harsh conditions.

Fess up. I live in Michigan—the suburbs of Detroit. Where does Southeastern Michigan water come from? Does it come from some pure spring-fed water source? Is that spring the Rouge River? Is your water indeed tap water? Tap water that you’ve “reverse-osmosis-ized”, mineralized, poured into a bottle, and sealed?

Let’s cut to the facts. I pay $36 a month for more water than I can use. I can just as easily fill a reusable bottle with my tap water, as I can buy your tap water. What’s my motivation to buy your tap water? The label? The sensuously curved bottle?

Also, as bottled water becomes increasingly “uncool” to drink (plastic bottles), your competitors have started making their bottles with much less plastic. What are you doing? I see you’re going to a 30% plant-based material composition. Why not go 100% non-plastic? Because that’s what tap water is doing these days.

Lots of questions.

Thank you for contacting The Coca-Cola Company, Jerry. We welcome the opportunity to respond to your concerns.

The water used to make DASANI brand bottled water is tested and approved water from municipal water systems. It undergoes further purification treatment in our plants.

To make DASANI water, we use reverse osmosis, which is a molecular-level filtration process. During this process, most minerals and impurities are removed from the bottling plant's incoming water supply. As a result of this treatment, the water used to make DASANI contains less than 10 parts per million of total dissolved solids. To improve the taste of our purified water, we add a small amount of mineral salts to it after completion of the purification treatment.

We made the decision to add minerals to DASANI based on consumer taste testing. Our research demonstrated that the addition of a very low level of minerals can improve the likeability of the water.

Please be assured that Coca-Cola brand soft drinks do not contain any harmful substances. DASANI and all Coca-Cola brand products are wholesome beverages manufactured in compliance with the federal law governing food safety and labeling, the laws of all the states, and the laws of over 200 countries throughout the world where they are sold.

Additionally, for future generations of the "PlantBottle™", we are looking at using other plants and plant wastes, such as wood chips, corn stover or wheat stalks. Our vision is to develop and commercialize PET plastic bottles that are made completely from renewable resources and are recyclable.

We hope this information is helpful and assures your confidence in our brands. If you have any additional questions, please feel free to contact us again.
