and some of their potential problems, concerns and requirements for use and reuse are discussed. Since the water is collected from below the surface, well water is classed as ground water. Well water usually has a higher dissolved soluble ion content but little or no insoluble suspended solids. Because the water has probably passed through rock formations the water is usually hard water, high calcium and magnesium. Therefore untreated well water often causes significant deposits, particularly in the hot water part of the system. Usually these deposits appear as rings or scum in plumbing fixtures. These deposits, as time passes, become very hard to remove. At the very least they require periodic cleaning. Eventually, these deposits will result in premature failure of the plumbing valves and fittings. Also, usually, more detergent or soap is required for cleaning and laundry when using well water. The hardness can be removed by passing the water through a sodium zeolite strong cation ion exchange softener that has been regenerated with salt. The calcium and magnesium will be removed and replaced with sodium ions. The water is then called softened water. Usually, the increase in sodium is not a concern. However, if a low sodium diet is required, depending on the amount of sodium added, softened water could be a concern. Because the calcium is removed softened water is corrosive to metals, especially when heated. Therefore, this fact should be considered when selecting the materials of construction for the water distribution system. An alternative to softening all the water is to soften only the water which will be heated. Unsoftened cold water is unlikely to cause deposit problems. Although not a health concern, well water often has iron and/or manganese contamination. Some or all of the iron and manganese is usually dissolved in the water and will pass through a particulate filter. Iron and/or manganese can cause unpleasant taste and create red, brown and/or black deposits especially in the fixtures of the system. such as sinks, bathtubs and toilets. If strange days the doors lyrics levels are high the iron can be reduced to an acceptable level by oxidation or aeration followed by filtration. Manganese is much more difficult to completely remove. Unfortunately, even a trace of manganese strange days the doors lyrics cause black deposits to accumulate in the system. The small amount of soluble manganese will be oxidized by air or by free chlorine residual, if present. This is particularly true when the water is heated. In addition, in strange days the doors lyrics cases, the water contains the gas hydrogen sulfide. Hydrogen sulfide causes the water to be very corrosive to metals and has a rotten egg odor. Dissolved hydrogen sulfide is difficult to remove completely.
