Water. We drink it, cook with it, bathe in it, and tell our children to drink more of it. We turn on the tap without a second thought and assume that what comes out is clean, safe and straightforward.
But three things landed on my desk this month that made me stop and think differently. And once you’ve read them, I suspect you will too.
This is not a scare piece. It’s an honest look at what the latest UK research is telling us about water – and what we can practically do about it as working mums managing households, health and increasingly curious children.
Your Children Probably Don’t Know Where Water Comes From
Let’s start with the one that surprised me most.
New research from Affinity Water, surveying 2,000 UK parents, found that one in three children believe drinking water comes directly from the kitchen tap – as in, it simply lives there, rather than arriving via reservoirs, underground aquifers, treatment works and miles of infrastructure before it ever reaches your home.
That’s not a small knowledge gap. That’s a fundamental misunderstanding of one of life’s most basic necessities.
But before we point the finger at the children, the same research found that two thirds of parents are significantly underestimating their own household water use – by up to 100 litres a day. Nearly one in three adults believe they use less than 50 litres daily, when the actual average in Affinity Water’s supply area alone is 156 litres. And 64% of parents admitted extending their showers beyond what is necessary – most commonly to enjoy the warmth, de-stress, or simply get a moment of peace and quiet.
That last one I will not judge. We all know what a shower that nobody is knocking on the door during feels like.
The broader picture is quietly concerning though. Only 57% of UK parents say they actively try to reduce water use at home. Nearly one in five believe serious water shortages in the UK are still decades away – despite the fact that parts of the country are already experiencing water stress today.
Affinity Water has launched something called The Great Water Hunt in response – a family activity turning children into “Water Detectives” who explore their local water systems and learn simple saving habits. It’s free, available both at locations across the UK and as a downloadable family handbook, and honestly it looks like a genuinely good rainy afternoon activity. You can find it at affinitywater.co.uk/keeplifeflowing/greatwaterhunt.
The Bigger Problem – What’s Actually in the Water
Here’s where it gets more serious.
Swedish water purification company Bluewater released a report this Earth Day highlighting something that scientists have been raising concerns about for years but that most of us have never been told clearly: everyday drinking water – both from the tap and from plastic bottles – contains a cocktail of substances that were never supposed to be there.
We’re talking about PFAS – so-called “forever chemicals” that don’t break down in the environment or in the body. Pharmaceutical residues that pass through wastewater systems not designed to filter them out. Microplastics now found everywhere from mountain snow to tap water. And phthalates – chemicals used to make plastics flexible – that can leach into water during manufacturing and packaging.
These aren’t theoretical future risks. They’re present now, in water being consumed daily by you and your family.
The regulatory picture is uneven. The United States has set strict legal limits on certain PFAS in drinking water. The European Union requires member states to monitor levels. The UK – and this is the part worth noting – currently relies on guidance rather than a single enforceable rule. That means the standard of protection varies, and the onus falls more heavily on individual households to make informed choices.
Some studies have linked certain PFAS to effects on the immune system and hormones. Microplastics and pharmaceutical traces are being examined for their possible impact on the body’s endocrine system. The science is still developing – but the trend is clear enough that experts are paying close attention.
What You Can Actually Do About It
I want to be clear: this is not a reason to panic. It is a reason to be informed and to make a few practical shifts.
Here is what the evidence points to as genuinely useful:
Filter your water at home. Not all filters are equal. Basic pitcher filters can reduce chlorine taste and some organic chemicals, but they don’t remove PFAS, lead or microplastics as effectively as reverse osmosis systems. If water quality is a concern in your household, it’s worth researching the filtration system that matches what you want to remove.
Switch from plastic to glass or stainless steel. Whether that’s your child’s school water bottle, your travel bottle, or the containers you store food in. Phthalates leach from plastic – reducing contact with plastic, particularly heated plastic, is a practical step.
Stop microwaving food in plastic containers. This one is simple, costs nothing, and is one of the easiest ways to reduce daily chemical exposure.
Talk to your children about where water comes from. Not to alarm them – but because a child who understands that water is a resource with a journey, not a tap that simply produces it on demand, is a child who will grow up making better choices. The Great Water Hunt from Affinity Water is a genuinely lovely way into that conversation.
Hydration on the Go – Getting the Basics Right First
There’s been a lot of noise in 2026 about hydration as a wellness priority – and the travel hydration market in particular has exploded, with brands pitching insulated bottles as non-negotiable packing essentials.
I’m going to offer a note of caution here. A premium water bottle is only as good as what you put in it. If you’re investing in a beautiful stainless steel travel bottle – which genuinely is a smarter choice than single-use plastic – make sure you’re also thinking about the quality of what goes inside it, particularly at home.
The conversation about hydration can’t just be about how much we drink. It also has to be about what we’re actually drinking.
What This Means for Your Family Right Now
As working mums, we already carry the mental load of managing household health decisions – food, sleep, screen time, wellbeing. Water shouldn’t be something we think about last, if at all.
The practical checklist is short:
- Find out what’s in your local tap water – your water supplier is required to publish this information
- Consider whether your current filtration setup matches the level of contaminants you want to reduce
- Switch plastic drink containers to glass or stainless steel where possible
- Have the water conversation with your children – where it comes from, why it matters, and how your family can use it more wisely
- Take 20 minutes this weekend to do The Great Water Hunt with the kids – it’s free, fun, and genuinely educational
None of this requires a significant spend or a lifestyle overhaul. It requires attention – and that is something working mums have always been quietly excellent at, even when the world doesn’t notice.
A Note on General Knowledge and School Preparation
If your child is preparing for the 11 plus or an independent school interview, the water knowledge gap highlighted in this research is a useful reminder that environmental awareness and general knowledge matter in these processes.
Interview panels and 11 plus verbal reasoning assessments regularly draw on a child’s understanding of the world around them – including how natural resources work, environmental challenges, and basic geography. A child who can speak confidently about where water comes from, why conservation matters, and what challenges the UK faces around water supply is a child who demonstrates exactly the kind of informed, curious thinking that assessors are looking for.
Exploring topics like this together at home is part of building that broader awareness – and The Great Water Hunt is a practical, enjoyable way to start.

The Bottom Line
Water is not a passive subject. It is something that flows through every part of family life – through our health, our children’s development, our homes and our habits. The research landing this month is a reminder that being informed about something as fundamental as what we drink is not alarmist. It is responsible.
Turn on the tap with intention. Filter with knowledge. Talk to your children. And if you get a moment of peace in a longer-than-necessary shower – I’ll say nothing.
