Is Your Dug Well Safe? Signs of Contamination & What to Do (Thunder Bay Guide)

Is Your Dug Well Safe?

Wondering if your dug well is safe? Learn the warning signs of contamination

Introduction

Dug wells are common across Thunder Bay and surrounding rural areas, especially at older homes, camps, and cottages.

But many of these wells were built decades ago — and may no longer meet modern safety standards.

If you rely on a dug well, it’s important to know the warning signs of contamination and when to take action.

Signs Your Dug Well May Not Be Safe

If you notice any of the following, your water may be at risk:

• Cloudy or dirty water

• Musty, sulphur, or unusual smells

• Sudden changes in water taste

• Surface water entering the well

• Bugs, debris, or visible contamination

• Frequent illness or stomach issues

These are signs your well may be exposed to bacteria or surface contamination.

Why Dug Wells Are More Vulnerable

Unlike drilled wells, dug wells are:

• Shallower

• More exposed to surface water

• Often built with older materials

• More likely to have unsealed covers

This makes them more susceptible to:

• Rain runoff

• Snowmelt contamination

• Animal or insect entry

• Bacteria and organic material

How to Make Your Dug Well Safer

There are several ways to improve the safety and reliability of your dug well:

✔ Install a Vermin-Proof Well Cap

Keeps out insects, rodents, and debris

✔ Raise and Seal the Well Lid

Prevents surface water from entering

✔ Upgrade Pump & Plumbing Connections

Modern systems reduce contamination risk

✔ Add Water Treatment Systems

UV systems, filters, and softeners improve water quality

When Should You Test Your Water?

You should test your well water:

• At least once per year

• After heavy rain or flooding

• If water appearance or smell changes

• After any work is done on your well

Regular testing is one of the easiest ways to protect your health.
