Global Quality of Safe Water

In a search to discover the current state of safe drinking water globally looking over reports that were created from information obtained from “International Journal of Environmental Research and Public Health”

The article begins by outlining the classes of drinking-water sources as outlined in the table below

Table 1. JMP Classification of drinking-water source types as improved or unimproved [2].

Source class Type of source
Unimproved drinking-water source Unprotected dug well, unprotected spring, cart with small tank or drum, surface water (e.g., river, dam, lake, pond, stream, canal or irrigation channel) and bottled water
Improved drinking-water source (piped to dwelling, plot or yard) Piped water connection located inside the user’s dwelling, plot or yard
Improved drinking-water source
(other sources)
Public taps or standpipes, tube wells or boreholes, protected dug wells, protected springs and rainwater collection

Using this approach, WHO and UNICEF estimate that 5.8 billion people used improved sources in 2010, with 783 million using unimproved water sources. Treating use of an improved source as an indicator for use of safe water is likely to overestimate the population using safe water, since some improved sources may provide water that is microbiologically or chemically contaminated whether at source or by the time it reaches the home and is consumed. On the other hand, most unimproved sources do not provide safe drinking water, so under-accounting of safe water coverage due to unimproved sources providing safe water is likely to be small (Onda, LoBuglio, & Bartram, 2012).

Much of the information presented has been provided by public acquired resources. AquaDrop ™ can be part of the solutions to begin to bring the amount of Unimproved water that has some microbiologically component. It has been shown from in the field use in countries that have some locations poor water quality. It can also be a great benefit for use in areas where camping and using water from sources that may be unknown.
