and customs in radical ways.
Clean and contamination-free
potable water is a valuable good which faces an ever increasing demand. But
sewage water contaminated with chemicals from industrial plants
and farms, households' waste water polluted with cleaning chemicals and
toxic substances from hazardous waste deposits are threatening our drinking
water. Waterworks, owners of self-sufficient and single-house supply systems, fed by their own
wells, find it more and more difficult to meet the legal standard because of
the increased pollution.
However, health risks due to water contamination are still insufficiently
researched, scientists only know the consequences of a few substances like nitrate,
nitrite, pesticides (e.g. Atrazin), pseudo-hormones, residues of
pharmaceuticals, lead, copper, phosphate, chlorine, etc. Some are considered to
cause cancer, to result in defects of the hereditary substance, to lead
to infertility, malfunctioning of
the nervous-system and the brain, to harm bones and the skeleton, to trigger
and concentration problems, and - in the case of nitrite - even cause
the deaths of babies.
legal limits are obeyed, but there are no studies yet which examine
the effects of the combination of harmful substances or consider
the formation of chemical compounds in the human body.
Scientists are warning of new
illnesses caused by micro-organism and resistant bacteria which have
increased in number due to usage of antibiotics in medical and
veterinarian science. In addition to that, scientists are worried about the resistance of bacteria and parasites
(Cryptosporidien, etc.) against the chemicals (chlorine, ozone) usually used
to purify water.
Almost any food is prepared with
or cooked in water, vegetables and fruits are
cleaned with water, most beverages like tea or coffee consist of water. Drinking water is
often boiled before consumption, but many substances cannot be eliminated in such a way.
Harmful substances find their way into
our body system. An average person consumes 55,000 liters of water in his

Of course, the long-term
solution to this problem is to deal with nature in a more reasonable way. To
ensure our families' health today, we have to take little steps such
as the purification of water.
