  1. I am a lifelong proponent for using tap water! Raised my kids and now my grandkids with awareness of our water challenges. I am writing today to find out how to enter for a chance to win a reusable vacuum sealed water bottle. LOVE the message on it. Cannot find info on the YourSoCalTapWater.og website.

    • Hi Debra,
      The contest ended on June 30th, but I would be happy to send you a water bottle. Please send me your address and please post a photo of you or your pet enjoying tap water and share with us via Facebook or Twitter. Also, please sign up to follow our blog if you haven’t already.
