Faucet Aerator III

Aerators should be regularly kept cleaned or replaced. The mesh in the aerator can collect lead debris, and then leach this toxic metal into the water passing through it. Aerators cap the ends of most drinking-water faucets. In some cases, they’re used to conserve water by reducing a faucet’s maximum flow rate; in others their primary function is to concentrate the flow of water so that it delivers more pressure and cleaning power. But these little metal cages also collect debris. Including lead. And unless you’re regularly cleaning out those aerators, you might be developing a toxic mini gravel field through which your drinking water must pass before reaching your glass or coffee pot. Indeed, one lead poisoning case in North Carolina involved a child (see link below): www.dcwater.com/waterquality/faqs.cfm
