An improved drinking-water source is defined as one that, by nature of its construction or through active intervention, is likely to be protected from outside contamination, in particular from contamination with fecal matter.
To allow for international comparability of estimates for monitoring the Millennium Development Goals (MDGs), the World Health Organization/UNICEF Joint Monitoring Program (JMP) for Water Supply and Sanitation defines "improved" drinking water sources as follows:
- Piped water into dwelling
- Piped water into yard/plot
- Public tap /standpipes
- Tubewell /boreholes
- Protected dug wells
- Protected springs
- rainwater collection
- Bottled water, if the secondary source used by the household for cooking and personal hygiene is improved
Water sources that are not considered as "improved" are:
- Unprotected dug wells
- Unprotected springs
- Vendor provided water
- Cart with small tank/drum
- Bottled water, if the secondary source used by the household for cooking and personal hygiene is unimproved
- Tanker-truck
- Surface water
Famous quotes containing the words improved, water and/or source:
“The liberal wing of the feminist movement may have improved the lives of its middle- and upper-class constituency—indeed, 1992 was the Year of the White Middle Class Woman—but since the leadership of this faction of the feminist movement has singled out black men as the meta-enemy of women, these women represent one of the most serious threats to black male well-being since the Klan.”
—Ishmael Reed (b. 1938)
““... You ought to have seen how it looked in the rain,
The fruit mixed with water in layers of leaves,
Like two kinds of jewels, a vision for thieves.””
—Robert Frost (1874–1963)
“The ungentlemanly expressions and gasconading conduct of yours relative to me yesterday was in true character of yourself and unmask you to the world and plainly show that they were ebullitions of a base mind ... and flow from a source devoid of every refined sentiment or delicate sensations.”
—Andrew Jackson (1767–1845)
