    Ksp=[Pb2+][Cl-]^2 by definition.

    You are given the KSP and Pb2+ values, simply find the concentration of Cl-. You will notice that you will need a LOT of salt to do this, and creating highly saline environments in water sources kills a lot of plants and wildlife.

    Ok, however don't do it with hot water, or you'll kill people (PbCl2 is quite soluble in hot water).
    Furthermore, precipitating Pb with Cl- obviously take in solution the anion and this one can be not appropriate itself for a drinking water: NO3- for example.

    This sounds more like Chemistry 101 homework than somebody with bad well water. But, you never know.
