Do You Trust Your Tap Water?

When most of us were kids, we played outside and drank water from the garden hose. Most likely you have traded in the garden hose for bottled or filtered water, but you still need tap water for several household uses. How much do you know about your water and is it safe to drink? The answer depends on where you live.

According to The Washington Post, Hexavalent chromium is being studied by the state of California as a possible carcinogen and has been found in the water supply of 31 cities. 25 of these cities are above the maximum safety level that this California study suggests.

Remember the movie Erin Brockovich? This is the substance on which that movie was based.  Hexavalent chromium is used for industrial practices like chrome plating and plastics manufacturing. The real Erin Brockovich, who is a legal advocate, says she wasn’t surprised by the report because so many factories are using it.

The issue with hexavalent chromium, according to the study by the state of California, is it causes cancer in rats. If California decides to limit the amount of this substance in drinking water, it will be the first standard like this in the U.S.

The highest level was from Norman, OK. Their figure came in at 200 times more than the safe limit (.06 parts per billion) proposed in the California study.

The Environmental Working Group (EWG) released the results of a three-year investigation of municipal water supplies across the U.S. The research and advocacy group looked at water quality tests performed by water utilities since 2004. The EWG also rated 100 cities’ water utilities with a population over 250,000.

Cities with the best water are Arlington, TX, Providence, RI, Fort Worth, TX, Charleston, SC, Boston, MA, Honolulu, HI, Austin, TX, Fairfax County, VA, St. Louis, MO and Minneapolis, MN.

Cities with the worst water are Pensacola, FL, Riverside, CA, Las Vegas, NV, Reno, NV, Houston, TX, Omaha, NE, San Diego, CA and Jacksonville, FL.

    That’s scary… people really need to get their water tested and get some sort of filtration system.
