Virginia Source Water BY SCOTT MCNALLY, SOURCE WATER TECHNICIAN most coveted resource of any living organism. A water molecule's journey through the hydrologic cycle can take it on a long voyage through many different transitions. Water can be found in solid, liquid or gaseous form, all of which are harvested by different cultures throughout the world. In these three phases it takes many different forms including clouds, ice, snow, rivers, lakes, groundwater and oceans. WATER IS THE In the U.S., a few water sources that are most commonplace fall into two categories: groundwater and surface water. Groundwater accounts for wells and springs while surface waters include rivers, lakes and reservoirs, just to name a few. Bottled water is another source but is largely a luxury and not readily available to many parts of the world. Tap water that is part of a community-based water system is the most common water source in the U.S. The defining characteristic of tap water is usually the intensive treatment process to ensure the water is safe to drink for a large population of people. This water has to be suitable for everyone from the elderly, individuals with weakened immune systems, and infants. With this in mind, properly disinfecting the water is important which is most often done with chlorine. Chlorine is an excellent choice because it provides a lasting effect from the plant to tap. Individual community water systems are often sourced from two or more of the sources listed above. Here in the great state of Virginia, we have a very strong presence of rural and agricultural communities. In these areas the density of human populations is not high enough to warrant the construction of a water treatment plant and distribution system. This is why roughly 37 percent of Virginia households get their water from a private Virginians are fortunate to have a wide selection of different water sources when so many areas of the world are plagued with drought or contaminated water sources source. The most common source in this state would be private wells, but if a property has an active spring, that can be used as well. These systems have some benefits and some drawbacks that may not make it the right source for everyone. In private systems, the water typically goes straight from the well or spring to the tap. For some systems this is a good thing because it delivers unaltered water in its pure, mineral-rich form. However, in some situations, these wells and springs are susceptible to contamination which can cause serious problems if the water is untreated. In karst regions, springs and 21
