Help me, someone

Here's the deal, I've decided to put a garden in the front of my parent's house for my mother before I go to college. We've got heavy clay soil so I've started some compost to correct the soil with and I've started digging (despite the intense california heat). Now imagine our surprise, after going to the local garden center to see what plants would be good for us as it seems our water keeps killing our house plants, to learn that there might be boron in our water. Does anyone know how to correct this apparently fatal water problem. There isn't enough to bother us humans, but plants are extra sensitive. Is there a filter we can buy? A mineral we can use? Any suggestions would be appreciated.
