Well Safety on Farms

A farm well is a lifeline for people and animals, and it needs steady attention. This guide covers the main safety ideas and points to the officials who set local rules.

What makes a farm well a safety concern?

Wells present two kinds of risk. The first is physical: open, uncovered or poorly covered wells, old hand-dug wells and well pits can injure or trap a person or animal. The second is water quality: contamination can reach a well through poor construction, damage or nearby activities.

Many farms have more than one well, including older wells that are no longer in use. Know where every one is, and make sure each is either properly maintained or properly closed according to local rules.

Because wells are out of sight, problems can develop quietly. Make a habit of looking at the whole system, not just the pump house, and write down anything that seems different from last time.

• Physical hazards include open tops and weak covers.
• Water-quality hazards depend on construction and surroundings.
• Old, unused wells need special attention.

Who sets the rules for wells where you live?

Well construction, repair and abandonment rules vary widely by state and sometimes by county. Many require licensed contractors for certain work. Do not rely on a neighbor's memory of what was allowed.

Contact your state or county health department or the agency that regulates water wells. They can tell you what is required for repairs, testing and closing old wells. Your extension office can also point you to publications written for your state.

• Ask which work requires a licensed well contractor.
• Ask how to close an unused well properly.
• Keep records of any work done.

How should you inspect your well regularly?

A simple routine inspection can catch problems early. Look at the well cap or cover, the surrounding ground, and any visible casing. Note cracks, gaps, standing water, signs of animals and anything that looks changed.

Do not open sealed wells or enter pits yourself. If something looks wrong, call a licensed professional. A well house or pit can also be a confined space with hazards, so do not enter it casually.

• Check the cover and cap for damage.
• Watch for erosion or settling near the well.
• Keep a written log of what you see and when.

What activities near the well need care?

What happens around the well matters. Chemicals, fuel, fertilizer, manure and equipment fueling can all affect water quality if placed too close. Extension and health officials can tell you what distances and practices apply where you live; ask rather than guessing.

Keep vehicles and heavy equipment from driving over the well area, and mark the well so that mowers and tractors do not strike it. Children and visitors should also know the well is not a play area.

Share any worries with the person who installed or serviced the well. A short phone call early can prevent a larger problem. Keep contact details with the well records.

• Mark the well so equipment does not hit it.
• Store chemicals and fuels away from the well as local guidance advises.
• Keep play areas away from the wellhead.

How do you check water quality?

Testing is how you learn whether water is safe to drink. Your local health department or a certified lab can explain which tests are recommended in your area and how often. Do not try to judge water by taste or smell alone.

Test after flooding, after any repair work, and if there are changes in taste, color or odor, or if someone becomes ill. Follow the lab's instructions for collecting samples, since mistakes can affect results.

• Use a certified lab for testing.
• Retest after floods or repairs.
• Ask your health department how often to test.

What about pumps and electrical work?

Well pumps and their wiring are electrical equipment working in damp conditions. Repairs belong to licensed electricians or well professionals. Never work on wiring near water or with wet hands, and always follow manufacturer instructions.

If you notice tingling, buzzing or tripped breakers near pump equipment, stop and call a qualified person. In an emergency involving electricity, call 911 and keep others away.

Before a pump is replaced or serviced, the power must be handled correctly by the qualified person doing the work. Do not attempt to turn power on or off at unfamiliar panels while someone else is working.

Where can you learn more?

The links below lead to extension and federal resources on farm safety and water. For rules and testing, the most reliable help is local: your health department, state well regulator and county extension office.

Teach everyone on the farm where wells are located and what to do if they notice damage. A shared understanding is a safety measure on its own.
