Water scarcity is the lack of sufficient available water resources to meet the demands of water usage within a region. It currently affects around 2.8 billion people around the world‚ on all continents‚ at least one month out of every year and more than 1.2 billion people lack the access to clean drinking water.[1] Water scarcity can be a result of two mechanisms: physical (absolute) water scarcity and economic water scarcity‚ where physical water scarcity is a result of inadequate natural water

Water resources are sources of water that are useful or potentially useful. Uses of water include agricultural‚ industrial‚ household‚ recreational and environmental activities. Virtually all of these human uses require fresh water. 97% of the water on the Earth is salt water. However‚ only three percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps.[1] The remaining unfrozen freshwater is found mainly as groundwater‚ with only a small fraction present

Water conservation refers to reducing the usage of water and recycling of waste water for different purposes such as cleaning‚ manufacturing‚ and agricultural irrigation. Water conservation programs are typically initiated at the local level‚ by either municipal water utilities or regional governments. Common strategies include public outreach campaigns‚ tiered water rates (charging progressively higher prices as water use increases)‚ or restrictions on outdoor water use such as lawn watering

Experiment 05 Water Hardness October 8th‚ 2013 The hardness of water was determined using the methods of titration‚ conductivity‚ and pH analysis. The mean and uncertainty of CaCO3 is 134±36.0 ppm. An error that could have potentially happened could be that the equivalence point was not correctly established causing inaccurate data. BACKGROUND: 1In hard water there is a high amount of mineral content present in the water. Most of the mineral content that is present
