For example, in areas with limestone, the water is more likely to pick up alkaline substances that neutralize acids. Higher alkaline water is "hard" water, with a pH of 8.5 or higher. Fewer minerals are picked up in places with more volcanic rock, so the water is more acidic or "soft," with a pH under 6.5.
