Microorganisms thrive in dark, wet environments.
Bacteria, mold, fungus, alge, and slime molds.
None of these have a benefit to your sump system.
Mold and bacteria can cause microscopic airborne particles containing allergens & chemicals with the potential to induce inflammation in the respiratory system.
Basically, if you can smell it, YOU ARE BREATHING IT!
Bacteria and mold in your sump system are sources of
volatile organic compounds in the air you breathe.
If you or your children spend time in the basement,
or have bedrooms in the basement, you want that air to be clean.
