Answer:
Most water systems test for lead as a regular part of
water monitoring. These tests give a system-wide

household faucet.
If you want to know if your home’s drinking water
contains unsafe levels of lead, have your water tested.
Testing is the only way to confi rm if lead is present or
absent.
Some faucet and pitcher fi lters can remove lead from
drinking water. If you use a fi lter to remove lead, be
sure you get one that is certifi ed to remove lead by NSF
International.
