Residents Reminded to Test Well Water, Take Steps to Prevent Impacts of Flooding

Press Release – Southeast Public Health

Localized flooding may be occurring in some areas and on some properties. Floodwaters and water ponding around wells can compromise the safety of your drinking water. Southeast Public Health (SEPH) advises residents whose wells have been directly affected by flooding to boil their water for at least one minute at a rolling boil before consuming it, or to use an alternate safe water source until testing confirms the water is safe to drink.

If your property is prone to flooding, consider the following tips:

• Monitor weather forecasts closely and take warnings seriously.
• Check your local conservation authority’s website and alerts for localized flooding risks.
• Ensure drainage ditches and similar features around your home are clear and able to function during heavy rainfall.
• Clearly label shut‑off valves and note the direction to turn off gas, water, and power. If rising floodwaters require you to leave your home, turn off utilities before evacuating, if it is safe to do so.
• Maintain your home to help prevent water from entering.
• Move items that could be damaged by floodwaters to higher areas when possible.
• Store chemicals, cleaners, fuel cans, and similar materials securely to prevent them from contaminating floodwater.
• Keep an adequate supply of fuel for generators and pumps in case of a power outage and store fuel safely to avoid contamination.
• Maintain a well‑stocked emergency kit, including important documents, cash, safe drinking water, food, and medications.

Well water testing

It is important to regularly test your well water for bacteria. Runoff from heavy rain or melting snow can affect drinking water safety. Bacterial contamination does not always change the taste, smell, or appearance of your water — testing is the only way to know for sure.

Public health recommends testing your well water at least three times per year, and after a weather event where flooding has occurred as it may impact water safety. If contamination is detected, appropriate action can then be taken to protect the health of your family.
