It also happens at your drinking water treatment plant around dinnertime. That is when most people turn the sprinklers on their lawns or use water for various household chores and cooking. If you taste chlorine in your tap water, fill a pitcher with water and let it stand uncovered in the refrigerator. The chlorine will evaporate and your water will taste better. Bottled water is not necessarily healthier than tap water.
Water quality depends on how well the source of the water is monitored, protected and analyzed.
Household treatment devices do not make tap water healthier. Filters can improve the taste and appearance of water, but they do not purify it. These devices must also be kept in good condition or they could lower water quality. Lead pipes and lead soldered pipes are particularly harmful to pregnant women and children. If you have concerns about this problem, have your water analyzed by a certified laboratory.
