Poorly Filtered Tap Water Not Good For Cancer Patients

A panel of scientists including epidemiologists, oncologists and the World Wildlife Fund (WWF) has launched an awareness campaign on the dangers of poorly filtered drinking water for people suffering from cancer.

While tap water is generally of good quality (92% on average according to the Committee), the water of some rivers, however, is polluted by agricultural pesticides. These chemicals are bad for people in frail health, especially those suffering from cancer and receiving treatment.

Dr. David Servan-Schreiber, the head scientist of the campaign, explains that in 2007 more than five million people were exposed to nitrate levels that were considered too high. Studies have shown the impact of a too high rate of nitrates on the risk of cancer. Dr. Servan-Schreiber adds that certain waters contain very high levels of pesticides and drug residues, capable of developing a disease.


In some rivers that are running nearby hospitals, there are drug residues from the urine of patients.

For example in Europe, this problem is relatively new in France. The filtration processes of these residues are not yet fully developed across the country. Dr. Servan-Schreiber explains that the consequences of mixing drugs are not yet known and should arouse suspicion.

Without being alarmist, WWF urges the French people to ask their city councils to inform them about the water quality and the latest tap water analysis. If the water is good then there is no cause to be worried. However, if it is polluted, people who are frail in health need to filter the tap water, or turn to the bottled mineral water, whose purity is controlled.
