Wells and Sewage Systems During Flooding

• If flood water goes over well, water is NOT safe to drink (or brush teeth, shower, or wash with)
• Flood waters usually contain fecal material and other contaminants from overflowing septic systems, agri run-off, or industry by-products,
• Common illnesses with exposure to flood water:
  • Skin tissue infections following cuts, scratches, abrasions, or insect bites
  • Deep tissue infections following puncture wounds or trauma
  • Diarrhea following ingestion of contaminated water
     

When To Test a Flooded Well:

• Anytime water has gone over well
• Water not over well but has sudden change in look (cloudy, silty), taste, or smell
   

After Water Recedes:

With help of certified well driller or contractor,

• Inspect for well defects from flood damage
• Pump well until water is clear
• Shock chlorinate the well and distribution system
• When it no longer smells of chlorine, test drinking water for Total Coliforms and E. coli.

Before you begin flood clean-up or the shock chlorination process, dress in appropriate safety clothing and equipment. Wear goggles to avoid contact with eyes, a pair of rubber gloves to protect your hands and rubber boots, as well as a waterproof suit, coveralls or a full-length apron to prevent discoloration of your clothing. These are the recommended procedures and guidelines only. If you are not comfortable performing this procedure personally, please call a licensed contractor to shock chlorinate your well for you.
