For those consumers who live in communities with tap water that fails to consistently meet federal clean water standards or simply tastes funny, the answer is not to drink bottled water. First, they should contact their local utility to request a copy of the Annual Water Quality Report, also called the Consumer Confidence Report. A water filter is the best option. Consumers can have their water tested for contaminants and then purchase a filtration system that removes the specific contaminants in their water. Local health departments often provide testing services, or have lists of accredited laboratories.

Filtration is much cheaper than buying bottled water. Most Americans pay about $2 per 1,000 gallons for municipal water service, according to the American Water Works Association. That translates to two thousandths of a penny ($0.002) per gallon. Filtering tap water with a unit under the sink increases the cost to about $0.10 per gallon, while a counter top unit increases the cost to $0.25 per gallon. In comparison, bottled water typically costs more than $1 for eight to 12 ounces. This is on top of the monthly water bills to cook, wash clothes and dishes, bathe, and flush the toilet.
