In Germany, drinking water must satisfy stringent quality requirements. In the United Kingdom authorities define spending of more than 3% of one's income on water as a hardship.[24]. Sources where water may be obtained include: Springs are often used as sources for bottled waters. Joseph Cotruvo, Victor Kimm, Arden Calvert. [52] Although the impact will vary from place to place, it is predicted that the amount of meltwater will initially increase due to retreating glaciers and then gradually decrease because of reducing in glacier mass. Africa and the Millennium Development Goals [. [72], Most water requires some treatment before use; even water from deep wells or springs. In emergency situations when conventional treatment systems have been compromised, waterborne pathogens may be killed or inactivated by boiling[75] but this requires abundant sources of fuel, and can be very onerous on consumers, especially where it is difficult to store boiled water in sterile conditions. In Germany, drinking water must satisfy stringent quality requirements. More than 2,000 children's lives are lost every day.

United States. [67] Microbial pathogenic parameters are typically of greatest concern because of their immediate health risk. Moreover, the Drinking Water Ordinance regulates the duties incumbent on the water suppliers and monitoring authorities; it specifies the microbiological and chemical parameters as well as radiological requirements that must be tested for and the frequency with which drinking water must be monitored.
