Padre Dam water meets all State and Federal water quality regulations and is absolutely safe to drink. Bottled water is regulated by the U.S. Food and Drug Administration (FDA) while Padre Dam's water is regulated by the U.S. Environmental Protection Agency (EPA) and the California Department of Public Health (DPH). Tap water is actually required to meet stricter reporting requirements than bottled water. Also, tap water costs a fraction of the cost of bottled water. The decision to drink bottled water or use a filtration system should be based on your particular taste preference.
