Is our tap water a healthy water?
Possible organic and anorganic contamination of tap water
High nitrate values in particular, caused by the fertilizer methods of conventional agriculture, should concern us all. The limit value for nitrate, a nitrogen compound which the body converts to carcinogenic nitrosamines is 50 mg per litre in Germany and 40 mg per litre in Switzerland today.
In Austria, the limit value was revised upwards from 25 to 50 mg per litre in 1995. For the youngest of us, such contaminant values are already much too high. The World Health Organisation (WHO) therefore recommends that water intended for babies does not contain more than 10 milligrams of nitrate per litre.
PI®-Power Compact removes over 99% of nitrate from your tap water without fail.
Medication residue in drinking water – signs of our modern era.
The following press reports show that the problem of medication residues reached the consumer long ago:
Additional pollutants potentially affecting the tap water.
The most critical pollutants of the tap water are heavy metals like lead, copper, nickel, zinc, cadmium, manganese, thallium and uranium. Additionally to those there are the radionuclides Radium 226, 228, asbestos fibres, bacterial contamination, medication residues of contraceptive pills and antibiotics, chemical pesticides (pesticides, herbicides) from agriculture. Public water supply companies are obliged by the drinking water ordinance to supply the consumer up to the house water connection with a quality of water that does not exceed the legal pollution threshold value. To meet the requirements waterworks use various physical and chemical purification methods like filtration, chlorination, ozone treatment or UV radiation. The house owner is responsible for the water quality between the house water connection and the tap, regardless of single-family or multi-storey buildings. Aged piping systems (more than 30 years old) made of lead are to be handled with special caution. It is not required to meet the 25 micrograms per litre limit, if the tap water flows through old lead pipes. Stagnant waters in such installations can show up to 330 micrograms per litre. Excessive contamination of the drinking water with copper is considered a possible cause of early childhood liver damage. Copper can get into the drinking water as a corrosive product in considerable amount, especially when it’s idle in copper pipes for an extended period. The limit value is two milligrams per litre. An excessive lead and copper contamination of the tap water is barely possible if the requirements of the drinking water ordinance are complied with and the domestic installation is executed by a professional.
PI®-Power Compact removes heavy metals and radionuclides guaranteed over 99% from your tap water.
