How to Ensure Your Drinking Water is Safe

While water from municipal systems is generally treated, it can still contain or become contaminated with:

• Bacteria and Viruses: Like E. coli or norovirus, which can cause diarrhoea, nausea, and fever
• Heavy Metals: Such as lead or arsenic, linked to developmental and neurological issues
• Nitrates and Pesticides: Often found in rural or agricultural areas
• PFAS ("Forever Chemicals"): Used in industrial products, now widespread in water supplies
• Chlorine and Fluoride: Usually added for disinfection, but excessive levels can cause side effects

Understanding what might be in your local water is the first step to taking action.

Sometimes, the signs of unsafe water are visible or noticeable to the senses:

• Unusual taste: Bitter or metallic flavour
• Strange smell: Chlorine, rotten eggs, or musty odours
• Cloudy or discoloured water: Can signal sediment, rust, or bacteria

However, many dangerous contaminants are invisible and tasteless. For that reason, it's important to go beyond appearance and regularly test your water, especially if you rely on a private well or live in an older home with aging pipes.

Here are steps you can take to protect your household:

1. Test Your Water Regularly

• Use certified home test kits or send samples to a lab for detailed analysis.
• If you're renting, request your landlord share recent testing results.

2. Use Certified Water Filters

• Install point-of-use filters (e.g., on taps or under sinks) certified to remove specific contaminants.
• Look for certifications from bodies like NSF or the Water Quality Association.

3. Boil or Disinfect Water If Needed

• Boiling is highly effective at killing bacteria and viruses.
• Use water purification tablets or UV light pens when boiling isn’t possible.

4. Maintain Your Plumbing

• Replace aging pipes, particularly if your home was built before 1980 (when lead pipes were more common).
• Flush your taps after long periods of non-use.

When living or travelling abroad, water safety becomes even more crucial:

• Research Local Water Safety: Know if the tap water is safe to drink in your destination.
• Use Bottled or Filtered Water: Especially for brushing teeth or preparing baby formula.
• Carry a Portable Filter: Lightweight devices like UV purifiers or filter straws are perfect for travel.
• Watch for Local Advisories: Follow guidance from health authorities in your region.

You don’t have to wait for a boil notice to take water safety seriously. Whether you're at home, abroad, or supporting your family's wellbeing, regular testing, using appropriate filters, and staying informed can help you avoid the risks of water contamination.
