Contamination in UK Drinking Water: Exploring Possible Causes of Cancer

Reading Time: 3 minutes
Access to clean and safe drinking water is crucial for our health and well-being. However, concerns have been raised about the contamination of drinking water in the UK. This blog aims to shed light on the possible causes of water contamination and its potential link to cancer. We will also provide general recommendations for ensuring the safety of your drinking water.

Understanding Water Contamination

Water contamination occurs when harmful substances enter the water supply, making it unsafe for consumption. Several factors contribute to water contamination in the UK, including industrial waste, agricultural runoff, ageing infrastructure, and inadequate treatment processes.

Pollution in Tap Water

Potential Causes of Cancer

While the majority of tap water in the UK meets strict quality standards, there are concerns about certain contaminants that might pose health risks, including cancer. Here are some potential causes of cancer linked to water contamination:

Chlorination Byproducts:

Chlorine is commonly used to disinfect water and kill harmful bacteria. However, the disinfection process can lead to the formation of disinfection byproducts (DBPs) such as trihalomethanes (THMs). Long-term exposure to THMs has been associated with an increased risk of bladder and colorectal cancer.

Heavy Metals:

Industrial activities and mining can introduce heavy metals like lead, arsenic, and cadmium into water sources. Prolonged exposure to these metals has been linked to various types of cancer, including lung, kidney, and liver cancer.

Pesticides and Herbicides:

Agricultural practices involve the use of pesticides and herbicides, which can leach into water sources and contaminate the drinking water supply. Certain pesticides, such as atrazine and glyphosate, have been classified as potential carcinogens.

Pharmaceuticals and Personal Care Products:

 Improper disposal of medications and personal care products can result in their presence in water sources. Some of these substances, including hormones and pharmaceutical residues, have been associated with an increased risk of certain cancers.

Drink Filtered Water

Ensuring Safe Drinking Water

To reduce the risks associated with waterborne contaminants, consider the following general recommendations for ensuring safe drinking water:

  • Use Water Filters:
    Installing a water filter in your home can help remove impurities and contaminants from your tap water. Look for filters that are certified to effectively remove chlorine, heavy metals, pesticides, and pharmaceutical residues. 
  • Follow Local Water Quality Guidelines:
    Stay informed about the water quality guidelines and regulations provided by your local water authority. They may offer recommendations or alerts regarding any specific contaminants of concern in your area.
  • Regularly Maintain Water Systems:
    If you have private water sources, such as wells, ensure they are regularly tested for contaminants and properly maintained. Follow the maintenance guidelines provided by professionals to prevent contamination.
  • Practice Proper Medication Disposal:
    Dispose of medications and personal care products safely by following the guidelines provided by local pharmacies or waste management facilities. Avoid flushing them down the toilet or sink.

Next Generation Water Filtration Technology

It is worth noting that advancements in water filtration technology have brought about exciting developments in ensuring the safety and quality of drinking water. One such innovation, developed by Fahren, is the revolutionary next-gen RO filtration technology, which utilises a multi-stage carbon and RO filtration process. This cutting-edge system not only enhances the taste of drinking water but also reduces the levels of pollutants commonly found in water sources. Additionally, it provides protection against limescale build-up, particularly in areas with hard and very hard water.

By taking proactive measures to ensure the quality of your drinking water, you can promote a healthier and safer environment for yourself and your family.
