You can talk to a water specialist (try talking to the water company or even a bottled water company or treatment center) to see if there are any other ways to safely adjust the pH.
Otherwise, you can try using baking soda or sodium carbonate (washing soda) to adjust the pH. Note that too much baking soda and sodium carbonate can affect your blood pressure. Here was a thread that had similar information. You can check out the links that I posted there.

You can also do some internet research to safely adjust the pH of your water at home. I'm sure there may be a kit or a step by step guide.
