Bacteria can enter drinking water in a variety of ways and pose significant health risks. From diarrhea caused by E. coli to severe pneumonia, many things can happen. Antibiotic-resistant bacteria pose an additional danger, especially for people with weaker immune systems. It is therefore essential to declare war on bacteria in drinking water. Peacefully, with a very good water filter. With filbec.
Although drinking water in Germany is generally very well monitored microbiologically, bacteria can enter tap water in several ways. First, they originate from raw water, i.e., groundwater or surface water, from which waterworks extract drinking water. Natural bacteria, such as coliform germs, can be present in the water, especially after rainfall or flooding, but are largely removed through treatment and disinfection (e.g., chlorine, ozone, UV).
Pipes and domestic plumbing can also contribute to contamination. Bacteria can settle on the inner surfaces of pipes as biofilm, especially in plastic pipes or when water stands for long periods of time. Deposits in tanks or fittings and rarely used pipes, such as in vacation homes or garden sheds, also promote the growth of germs. Examples of bacteria that can be found in tap water includeLegionella, which mainly multiplies in hot water systems above 25°C,coliform bacteria or E. coli, which indicate fecal contamination, andPseudomonas aeruginosa, which is particularly relevant in medical facilities.
