or through reverse osmosis RO to remove virtually all the dissolved solids and higher molecular weight organics. However, since the water will have virtually no calcium, reverse osmosis treated water will be corrosive, especially when it is heated. The water may need to be treated to reduce its corrosiveness. In addition, the corrosiveness needs to be considered when selecting materials of construction of the water distribution system. To optimize its useful life, be aware all oxidants must be totally removed from the water before passing through a RO unit. This is because the membranes in all small home systems are very sensitive to oxidants. As a result the water is usually passed through a GAC to remove the oxidants. Unfortunately, the GAC, unless frequently changed, will act as source of bacteria that foul the membranes in the reverse osmosis device. Surface waters Streams, ponds, lakes, rivers, spring, and roof-collected water Generally, surface water has lower dissolved solids and therefore the water is usually not high in calcium or magnesium. In addition, generally iron and manganese and sulfide are not a concern. However, there strange days matthew good lyrics exceptions. Some surface waters have all of these contaminates present. What is usually a typical concern with surface water are suspended solids. Suspended solids are insoluble particulates in contrast to dissolved ions that are not dissolved in the water. Therefore, if the water from the roof or from a surface water source such as a stream or pond is used for domestic water, filtration is nearly always required to remove the suspended solids. In addition, bacteria are usually much higher in surface waters compared to ground water. Treatment to consistently destroy all of the bacteria is required if the surface water will be used for potable drinking water use. Water collected from the roof of a home is likely to be much lower in dissolved solids, even less than water from most rivers, streams, creek, pond or other surface water. As a result collected water from the roof, after filtration to remove suspended solids, is usually excellent quality water for watering plants, yards, gardens, and green houses. A major strange days matthew good lyrics why most off-grid homes prefer conventional roofs with gutters and downspouts rather than sod roofs is because collected roof water is low in dissolved ions, low salt content. However, because the roof water has little hardness, water collected from the roof of a home will also be very corrosive to all metals, especially when heated. This fact needs to be considered in the materials of construction used in the distribution system if the water from the roof will be used for domestic hot water purposes inside the home. The take home from this article: Water quality is critical for an off-grid home. Therefore before you purchase land for an off-grid home, have the water source or sources tested for inorganic, organics and bacteria. Contact your local health authorities for specific sampling requirements, local certified laboratories and advice and interpretation of results of the tests. People in my rural area mostly drink from springs or shallow wells. Most of these test positive for coliform bacteria, though not necessarily for fecal coliform, which is a subset of coliform bacteria. The former is a very broad group and doesn t really mean that your water is contaminated, necessarily. The latter comes directly from the guts of animals like us and does mean your water is contaminated. Most people have no problem drinking water that has some coliform bacteria in it, though people with compromised immune systems may. That said, we opted to send our well water through a sediment filter and a UV light to deal with coliform bacteria just so that our guests would be safe. Water, its everywhere. Two thirds of the earth is covered with it. We drink it, bathe in it, and a strange days matthew good lyrics part of our body is made of it.
