In fact, it has won national awards for tasting very good and not containing impurities. It just contains more acid than water in most other places. Our plants and animals are adapted to these acid conditions. It is important for us to protect the Pinelands so that the water will always be pure and not polluted. A pH of less than 7.0 means something is acidic, while a reading of more than 7.0 means something is alkaline.
Scientists often use sophisticated instruments to measure the exact pH of a substance.
You can find out if something at home is acidic or alkaline by doing the following experiment. Next have one of your parents poor the hot water into the bowl to soak the pieces of cabbage. Let the water cool and wait for it to turn purple. Your family can use the rest of the cabbage for salad one night, or you can feed it to a rabbit if you have one. After the water has turned purple, hold the strainer over the second bowl and separate the water from the cabbage by pouring it through the strainer.
