Northern Virginia and Washington are rapidly increasing in population, and as more and more people moving to the region, the question being asked more and more often – is the quality of my drinking water?
Individuals and seven & # 39; and, of course, care about their health, and drinking water from the & # 39 is an important part of maintaining good health.
Unfortunately, the quality of water in Northern Virginia and Washington DC are very bad and getting worse. Pollutants, bacteria, minerals, and chemicals in the tap water are masked by high doses of chlorine and tap water, except that they are ill, tastes and smells terrible.
Resolution of the Environmental Protection Agency (EPA) does not remove the dirt, but simply sets a maximum level of contaminants that can enter the human body and cause long-term damage.
Water is also polluted, but there is no federal or state agency that would regulate water wells.
What is the history of tap water?
Tap water – municipal water, which typically is pumped from nearby rivers, and then processed in accordance with EPA requirements. Processing is usually carried out through the apparatus for waste water purification with the addition of a large amount of chlorine to kill bacteria which remained that processing does not fall. It is important to note that EPA guidelines lies in the fact that they set a minimum permissible levels of pollution, which may ultimately harm both adults and children.
In Northern Virginia and Washington drinking water is pumped from the river mainly descendant and at least one station for cleaning the waste.
Contaminants that may be present in the well water include:
Microbial contaminants, such as viruses and bacteria that may come from sewage treatment plants, septic systems, agricultural activities and livestock.
Inorganic contaminants such as salts and metals, which may occur in nature or result from urban stormwater runoff waters, industrial or household waste water, oil and gas production, oil and agriculture.
Contaminants also include pesticides and herbicides, which may come from various sources, such as agriculture, urban stormwater runoff and domestic use.
In addition, contaminants can comprise organic chemical contaminants, including synthetic and volatile organic chemicals, with & # 39 are byproducts of industrial processes and production of oil and can come from a filling station, city urban runoff water and septic systems.
Radioactive contaminants that may occur in nature or be the result of oil and gas, and mining also affect the local tap water.
Which is a source of water in Northern Virginia and Washington DC?
The river descendant Anakostyya River and Rock Creek flows into the area from outside the jurisdiction. For example, a descendant of the river begins in West Virginia, and the river Anakostsiya – Maryland. Thus, the quality of water in Northern Virginia and the District of activity affects the entire watershed.
Storm water runoff from commercial, industrial, residential and agricultural areas, in terms of pollutants from sewage treatment plants and industrial discharges, as well as joint sewage flows from West Virginia and Pennsylvania – all contribute to the quality of water in the District and Northern Virginia. .
As for the combined sewer overflow (ETC)
ETC frequently occur when natural events such as floods, overcome power
Sewage treatment plant and raw sewage is retracted in a water source like a river descendant.
During periods of heavy precipitation power combined sewer may be exceeded. When this happens, the controls are designed to ensure that the excess flow that is a mixture of storm water and sanitary waste disposed of directly into the river Anakostsiya, Rock Creek, river descendant or tributaries. This excess flow is called a combined sewer overflow (OPS).
The liberation of the excess flow is needed to prevent flooding in homes, basements, factories and on the streets, but it adds bacteria and pollutants as a potential threat to the tap water.
As part of the tap water comes from sewage treatment plants OPS, may adversely affect the quality of our waters, coming in several ways:
UTS contain substances which promote high levels of bacteria in waters. The organic material in the ETS can facilitate reducing the levels of dissolved oxygen, which may contribute to stress or potential fish kills of fish, especially in the summer months; and trash in the ETS, such as plastic bottles, Styrofoam cups (otherwise known as "floating"), contribute to poor aesthetics.
How much is safe to drink good water?
Well water, a popular alternative to tap water, especially in Northern Virginia, subject to the same contaminated groundwater, waste chemicals and organic waste, and the tap water, but NOT in any way regulated by federal or state authorities.
In addition to the discharge of unpleasant sulfur odor and sediment from water Northern Virginia well contains a significant amount of iron in the rocks, in some areas, particularly in the P & C # 39; and Cote emontse ridge, which leads to iron staining. Sulfide in ground water is also found in parts of the valley and the mountain range, where coal or natural gas, causing an unpleasant odor.
Ground water, which is a & # 39 is the source of wells may also be contaminated by human activity. Bacteria from septic tanks and nitrates both septic tanks and fertilizer to the & # 39 are among the most common contaminants. As the water from the wells is not regulated, kaliynasts and potability, private well, with & # 39; is the responsibility of the homeowner and many private wells are contaminated.
Treatment of drinking water from wells
Website of Virginia strongly recommends to clean the well with chlorine to kill bacteria in well water and trying to overcome the unpleasant smell and taste of chlorine, de hlaratsyya. Again, this process is not controlled by any state or federal agency.
Two common types of water purification – is disinfection and air conditioning. To ensure that the food was not harmful bacteria, the water is disinfected.
Unwanted tastes, odors, and are removed by means of air conditioning.
Methods well disinfection
Drinking water is usually tested on koliformnyya bacteria living in the intestines of animals tsoplakrovnyh. Coliform bacteria are typically in the borehole with & # 39 are the result of a faulty septic system or contaminated surface water, which fall into the hole or in the water supply system.
Materials and tools that are used in the construction of wells is often contaminated with bacteria, which live in the soil, and they can be made to the water supply system in the construction of wells, installation of components of the pipeline system or servicing any part of the water supply system. Virginia strongly recommends to disinfect the water system after construction and after repair of wells.
Chlorination is used to disinfect private supplies because it destroys bacteria within a reasonable time of contact and provides residual protection. However, the conventional level of chlorination is not always effective in destroying Giardia cysts that cause severe gastrointestinal disease. Ultra high level of chlorination, boiling and filtration – the only effective methods for destruction or removal of cysts.
A high concentration of chlorine may have unpleasant tastes and odors, and even low concentrations of chlorine reacts with some organic compounds, creating a strong, unpleasant tastes and smells.
To eliminate these objectionable tastes and remove the excessive amount of chlorine water is then dechlorinated. Filters with activated carbon & # 39 are the most common tools used for water dehlaryravannya, removing unpleasant chlorine taste and reduce corrosion of plumbing systems.
How safe is the water supply and water to drink?
Municipalities, owners of wells and even the EPA claim that tap and drill water in Northern Virginia and Washington DC is perfectly safe to drink, but be surprised. Consider a source of tap water in the light of the wastewater treatment, concentration of chlorine addition and discharge into the river waste descendant and begin to wonder. Also note that the water from a well is subjected to most pollutants of tap water, but also can not be adjusted.
Or & # 39 is bottled water tap alternative?
Or not, depending on the type and quality of bottled water. Purified water is considered by many experts the best.
The popularity of bottled water has grown immensely, when Americans strive for a healthy lifestyle and better tasting water. But not all bottled water is healthier than tap or a good alternative.
Up to 25% of the bottled water on the market – it is simply tap water, packaged in plastic bottles and bottled water that is not purified often contains minerals and other contaminants that could harm your health. These contaminants are not only unhealthy and affect the taste of water, but also limit the storage time for emergency drinking water supplies.
Purified Water, however, by distillation and oxygenation process water trough provides the safest and best tasting alternative contaminated drill and tap waters in North Virginia and Washington.
Distillation removes the pure water from contaminants and oxygenation creates a fresh, light taste of the water.
Clean water is essential for the creation of a healthy lifestyle and good health for you and your family & # 39; and.
