What’s In Your Bottled Water?
July 31st, 2009 by Julia
Melanie Vanderveer, a writer for the Pocono Record, wanted to know. She purchased some water quality test kits and three popular bottle waters: DASANI, Aquafina, and Fiji water. She also tested her local tap water in Stroudsburg, PA. The findings are somewhat alarming.
Vanderveer tested for “pH, total Alkalinity, total chlorine, total harness, iron, copper and nitrates.” Iron, copper and nitrates were fine. Not the case with the pH and the alkalinity.
She quotes Michael Ronco, a scientist with FX Browne, Inc. which is a nationally recognized environmental consulting firm. “The Pennsylvania Department of Environmental Protection recommends a range between 6.5 and 8.5 for pH.” A level that is too low is can be too acidic. The results?
Aquafina’s pH level was 2! “According to the water quality test kit, that is a dangerous level.” Vanderveer tested two more bottles, purchased at different stores with the same results. Ronco says “A pH that low could potentially cause harm. Soda has a pH of around 4.” The tap water from Stroudsburg and DASANI had pH levels of 5. “That’s in the caution range.” Fiji fared the best with a pH of 6.5…but let’s not forget the environmental impact of Fiji!
Next, she tested the Alkalinity of the water. “Alkalinity is the measure of waters ability to neutralize acid. The alkalinity of Aquafina was low.” DASANI’s was zero, the tap water was 180 (ideal) and Fiji’s was 240 – which is high.
“The alkalinity correlates with the pH. It’s very acidic. The water has no ability to neutralize the acid,” Ronco said. “The source has a major impact on the quality of the water. It could be the plastic they use. Plastic leaches ions out of the bottle at high temperatures.” (As I’ve been saying since before we started H2Ox2 – how do you know where your bottle’s been before you bought it?)
“All four types of water had safe chlorine levels.”
Fiji and DASANI registered 120 for hardness of water. Stroudsburg and Aquafina were at ideal levels. “The hardness of the water is the measure of calcium and magnesium ions. Water hardness isn’t regulated,” Ronco said. “Hard water has a lot of mineral content.”
Nitrate levels were in the safe zone for all waters.
Interesting findings to be sure. On top of those ions leaching out of these plastic bottles, what’s leaching in?
Your best bet? Buy a reuseable metal bottle from H2Ox2 and fill it with your tap water. If you’re unsure about your water quality, buy a home test kit and find out. Filters, like the one we sell, can be reasonable and easy to install!
