Hurricanes may have an impact on the infrastructure and the water quality of private water wells. Heavy rains and flooding are the primary concern, but your well could also sustain damage to well components and have electrical issues after a hurricane. Wells that are damaged or that were under floodwaters are at risk of being contaminated.
Contaminants are a major concern, especially when industrial facilities such as chemical plants are damaged in a hurricane. Microorganisms such as bacteria, protozoa, or viruses are a concern when there is heavy rain and flooding. Hurricanes can lead to a septic system becoming flooded as well which can lead to sewage, bacteria, and other microorganisms contaminating drinking wells. Another concern can occur when storm surges cause ocean water to inundate water wells in coastal areas. The surging saltwater can led to saltwater intrusion.
Check with your local emergency management agency, health department, or other similar agency for more information about local conditions or specific contamination threats. To find available resources, search the internet for "[Your state][hurricane name] resources." For example, the Federal Emergency Management Agency (FEMA) will often post a memorandum announcing that residents affected by certain natural disasters may be eligible to receive funds for damaged wells and septic systems like this FEMA Damaged Wells and Septic Systems fact sheet from Hurricane Idalia in 2023.

If your water well has been impacted by a hurricane, follow these essential steps to assess and address the situation:
Safety First: Ensure your safety and that of your family. Avoid floodwaters and any electrical hazards near the well. If you suspect damage to the well structure, keep a safe distance until it can be inspected.
Inspect the Well: Once you have determined it is safe, examine the well casing, cap, and surrounding area. Look for cracks, leaks, or signs of damage caused by the hurricane. Also, check if any electrical components (such as the pump) have been submerged or damaged. If so, do not attempt to use them until they are professionally evaluated.
Test the Water: Collect a well water sample and have it tested for contaminants. Watch for any changes in water color, taste, or odor. Discoloration or unusual smells may indicate contamination. Use bottled water until you know your well water is safe to drink.
Disinfect the Well: If floodwaters have entered the well, disinfection is crucial. Follow these guidelines for chlorinating the well. Consult a professional or local health department for more information.
Address Structural Damage: If the well casing is damaged, consult a well professional to repair or replace it. Also, inspect plumbing connections and the pump system. Repair or replace any compromised components.
Elevate Electrical Components: If your well has electrical components, elevate them above potential flood levels. This prevents water damage during future storms.
Monitor Water Quality: Continue monitoring water quality after the hurricane. Regular testing ensures your well remains safe for consumption.
Consider a Well Inspection: If you are unsure about the condition of your well or if you suspect damage, consider having a professional inspect your well to assess the situation and recommend any necessary repairs.
