What’s in Your Irish Tap Water? A Breakdown by Region

Wondering what’s really in your tap water? Discover the most common contaminants in Irish water by region — and how to protect your home with the right filtration system.

Do You Really Know What’s in Your Tap Water?

Ireland is known for its lush greenery and natural beauty — but when it comes to tap water, things aren’t always as pure as they seem.

Depending on where you live, your water could contain chlorine, limescale, heavy metals, pesticides, or even microplastics. These issues vary across the country based on water sources, treatment facilities, and pipe infrastructure.

In this blog, we break down the most common tap water concerns by region — and share what you can do to keep your water (and your family) safe.

💧 Common Contaminants Found in Irish Tap Water

• Hard Water (Limescale) – High in calcium and magnesium
• Chlorine – Used for disinfection, often affects taste and smell
• Lead & Copper – From old pipes in older homes or public infrastructure
• Nitrates & Pesticides – Especially in rural areas due to agricultural runoff
• Microplastics – From surface water sources and urban pollution
