| | Fresh water - Wikipedia, the free encyclopedia |
 | | Fresh water is water that contains only minimal quantities of dissolved salts, especially sodium chloride, thus distinguishing it from sea water or brackish water. | | | Most species cannot live in both fresh and salt water, though some species move between the two, in brackish water. | | | Freshwater fish do the opposite: they have too much water, and too little salt. |

| | In concert with this goal is to also provide state-of-the-art water treatment equipment to purify water, especially for the many existing water supplies that have been contaminated with various forms of pollution for many years. | | | In these regions, Global Water plans to drill a series of wells that can be used to supply safe drinking water supplies to tens of thousands of people during all conditions, but especially during periods of drought. | | | Where no water supply exists or only polluted water is accessible in an area, the answer may be to dig water wells below surface pollution to access uncontaminated water supplies. |

| | Human Appropriation of the World's Fresh Water Supply |
| | Today, principal demands for fresh water are for irrigation, household and municipal water use, and industrial uses. | | | Although water is seemingly abundant, the real issue is the amount of fresh water available. | | | Some believe that fresh water will be a critical limiting resource for many regions in the near future. |

| | Fresh Water Resources |
| | The amount of fresh water is, of course, dependant on rainfall and this varies according to the geographic location of the island and climate conditions. | | | Even where the fresh water source is protected from pollution, tap water from urban systems is seldom safe to drink because of leaky pipes and negative water pressure during times of high use. | | | There is normally a “wet season” that replenishes water supplies for the subsequent dry season. |

| | When we measure the salinity of water, we look at how much dissolved salt is in the water, or the concentration of salt in the water. | | | Concentration is the amount (by weight) of salt in water and can be expressed in parts per million (ppm). | | | Slightly saline water - From 1,000 ppm to 3,000 ppm |

| | In addition, the water table tends to rise closer to the surface so there is inadequate drainage to carry the salts past the root zone of the plants. | | | Over the years of irrigation there is a tendency for the salts in the water to build up in the soil. | | | Some investigators list up to 1/3 of fresh water fish species as in danger of extinction. |
