Most homes in the service area do not have lead issues with their tap water. Also, simply running your tap for 30 seconds, after the water has been sitting for several hours, is usually a much cheaper and more effective alternative to a filter or bottled water.
Also, some water filtration systems do not remove lead. Before you purchase a filter, you should verify the manufacturer's claim. A good resource is the National Sanitation Foundation website or at 1-877-867-3435. If your water has elevated levels of lead after flushing, bottled water is an option, but it may cost as much as 1,000 times more than tap water.
