    The problem

    Chlorine or chloramine taste is common in city water. Sulfur or earthy smells are more common in wells.

    Hot-water-only odors often point to the water heater, not the supply.

    What public data can and cannot say

    Cannot tell you

    How to test

    • Compare cold and hot taps.
    • A basic kit can check chlorine; wells may need a lab panel.
