Hard Water In Sweden

The Swedish water supply contains more impurities than you might expect, with groundwater being affected by agriculture, industry, and household activities. Below, you can review the water quality in your municipality.

What is Hard Water and Its Effects?

Hard water contains elevated levels of calcium and magnesium, which it picks up naturally as it filters through mineral-rich soils and bedrock. While not harmful to health, hard water can significantly impact daily life and household systems.

Mineral deposits, or limescale, from hard water can build up in pipes and appliances, reducing water flow and the efficiency of devices like dishwashers and washing machines. It can also lead to dry skin and rough, lifeless hair, as minerals disrupt the skin’s natural barrier. Additionally, hard water reduces detergent effectiveness, leaving fabrics stiff and faded over time.

Common Impacts of Hard Water

  • Limescale

    Visible buildup in pipes and appliances

  • Dry Skin & Hair

    Minerals disrupt natural moisture

  • Soap Inefficiency

    Reduced lather and residue buildup

  • Appliance Wear

    Shorter lifespan for machines like dishwashers

Understanding Water Hardness in Sweden

Water hardness in Sweden can vary significantly depending on the region. Areas with high limestone content in the soil tend to have harder water, while regions with softer minerals have a lower concentration of calcium and magnesium. To understand how hard the water is in your municipality, refer to the interactive map below, which provides a comprehensive overview of water hardness levels across the country. By knowing the hardness of your water, you can better assess the need for a water filter or other solutions to reduce the effects of hard water on your home.

Water Hardness Levels

  • Soft Water

    Low mineral content, gentle on appliances

  • Moderately Hard Water

    Some mineral buildup, common in cities

  • Hard Water

    High calcium and magnesium, causes limescale

  • Very Hard Water

    Significant scaling in pipes and appliances

Beyond Hardness—What Else is in Your Water?

While hardness is a key concern, water in Sweden can also contain other substances that affect your health and the environment. Pesticides, heavy metals, PFAS (per- and polyfluoroalkyl substances), and nitrates are commonly found in water sources due to agricultural activities, industrial processes, and municipal discharges. These contaminants can lead to long-term health risks, including cancer, kidney damage, and hormone disruption. Understanding these pollutants and monitoring their levels is crucial in making informed decisions about your water quality. For more detailed information on the presence of these substances in Swedish water, you can refer to Naturvårdsverket and Svenskt Vatten.

Potential Contaminants In The Water

  • Pesticides

    From agricultural runoff

  • Heavy Metals

    Lead, copper and others from old pipes

  • PFAS

    Persistent industrial chemicals

  • Nitrate

    From fertilizers or sewage

Why Clean Water Matters

Clean, filtered water is essential for maintaining your health and the functionality of your home. Aside from the obvious benefits like better taste and safety, filtered water can also improve your skin and hair health by removing harsh minerals that can cause dryness and irritation. Moreover, using a water filter can extend the life of your appliances, such as dishwashers and washing machines, by preventing limescale buildup. Cleaner water also contributes to a healthier environment, as it reduces the need for bottled water and minimizes the impact of contaminants in wastewater.
