10 Compelling Reasons Why You Need su arıtma cihazı

[Dung Gisele]

In the year 1999 - 2000, drinking contaminated water from the private well caused 26% drinking water epidemic and made people sick in the U.S alone. The U.S. Environmental Protection Agency's (EPA) rules that protect public drinking water systems do not apply to privately owned wells. Most states have rules for private wells, but these rules may not completely protect your private well.

As a private well owner, you have to make sure that well water is safe enough for drinking. The local health authorities in your area or environmental department can help out advice you.

Check Your Well Water System

Make sure to check well every spring to monitor any mechanical problems; test it once each year for germs and once every two to three years for dangerous chemicals. You should also have your well tested if there are known problems with well water in your area, or you have experienced problems near your well i.e., flooding, land disturbances, and nearby waste dumping sites or you replace or repair any part of your well system.

To Determine Whether Well Water is Contaminated

The only way to discover, if the well water is contaminated is to test it. You can get in touch with your health department or your environmental department, or a private water testing laboratory in your area to test for germs and unsafe chemicals. It is a state rule in some areas for the drilling contractor to test a new well after it is built. On the other hand, as a private well owner, it is up to you to preserve your well and have it tested frequently.

Germs and Chemicals in Well Water

Germs and chemicals can get into your well water and contaminate it in various ways. Some germs and chemicals crop up naturally. For example, heavy metals like arsenic, lead, and cadmium are naturally found in rocks and soil and sometimes leak into ground water. Other pollutants come from human and animal waste resulting from polluted storm water runoff, agricultural runoff, flooded drains, or individual septic tank systems that are not working appropriately.

Types of Germs and Chemicals Found

Certain germs and chemicals can cause illness in drinking water and be a risk to your health. Frequent tests should be performed, which are listed as follows:

Total Coliform - Coliform bacteria are microbes found in the digestive systems of warm-blooded animals, in soil, on plants, and in surface water. If the total coliform count is high, su arıtma then it is very possible that harmful germs like viruses, bacteria, and parasites might also be found in the water.

Fecal Coliform / Escherichia coli - Fecal coliform bacteria found in feces (or stool) and digestive systems of humans and warm-blooded animals contain millions of fecal coliforms. These harmful germs can cause diarrhea, dysentery, and hepatitis.

Nitrate - Nitrate are naturally found in many types of food, but high levels of nitrate in drinking water can make people sick. Nitrate in your well water can come from animal waste, private septic systems, wastewater, flooded sewers, polluted storm water runoff, fertilizers, agricultural runoff, and decaying plants. A nitrate test is recommended for all wells. If the nitrate level in your water is higher than the EPA standards, you should look for other sources of water or ways to treat your water.

Volatile Organic Compounds (VOCs) - VOCs are industrial and fuel-related chemicals that may cause bad health effects at certain levels. Ask about testing for are benzene, carbon tetrachloride, toluene, trichloroethelene, and methyl tertiary butyl ether (MTBE).

pH -The pH level tells you how acidic or basic your water is. The pH level of the water can change how your water looks and tastes. If the pH of your water is too low or too high, it could damage your pipes, cause heavy metals like lead to leak out of the pipes into the water, and eventually make you sick.

Other germs or harmful chemicals

Other germs or harmful chemicals that you should test for will depend on where your well is located on your property, which state you live in, and whether you live in an urban or rural area. These tests could include testing for lead, arsenic, mercury, radium, and other pesticides.

Remember that if your test results say that there are germs or chemicals in the well water, you should contact your local health or environmental department for help and test your water more often.

What if the Well Water has Odd Smell or flavor

An alteration in your water's taste, color, or odor is often not a health concern. Still, a change could be a sign of serious contamination problems. If you notice a change in your water quality, you should have it tested.

Where to go for well water tests

Local or State health or environmental departments often test for bacteria and nitrates. Health or environmental departments, or county governments should have a list of the state-certified (licensed) laboratories in your area that test for a variety of substances.

Different Processes of Water Treatment

We need clean, safe water in everyday living. It is very important for the community's well-being, hygiene and productivity.

The process of treating water may slightly be different at various places, depending on the technology of the plant that needs processing. Nevertheless, the principles are basically the same. The following section will give you a description of the different standard water treatment processes.

Coagulation / Flocculation

During the process of coagulation, liquid aluminum sulfate or alum and/or polymer is mixed with raw or untreated water. The mixture causes the tiny dirt particles in the water to stick to one another or coagulate. Then, these dirt particles form groups that stick together and form flocs, larger heavier particles that can be removed easily by filtration or settling.

Sedimentation

When the particles of water and flocs go through the treatment process, they flow into the sedimentation basins. Here the water runs slowly, letting the heavy floc particles settle to the bottom. Floc that accumulates on the bottom of the basin is known as sludge, which is channeled to drying lagoons. Direct Filtration does not include the sedimentation step, and filtration is the only process by which the floc is removed.

Filtration

Water passes through a filter intended for removing particles in the water. The filters comprise layers of gravel and sand and, at times, crushed anthracite. Filtration gathers the suspended impurities in the water, then further enhances the efficiency of disinfection. The filters are cleaned on a regular basis thorough backwashing.

Disinfection

Before water moves into the distribution system, it is disinfected to make sure that disease-causing bacteria, parasites and viruses are destroyed. Chlorine is applied because it a great disinfectant, and the remaining concentrations can be maintained to protect from probable biological contamination in the distribution of water.

Sludge Drying

Solids collected then settled outside the water via filtration and sedimentation are piped to drying lagoons.

Fluoridation

This is the treatment of community water aimed at adjusting free fluoride ion concentration to the optimum level enough to minimize dental caries. It is a requirement for Hunter Water to fluoridate water in compliance with the NSW Fluoridation of Public Water Supplies Act 1957.

pH Correction

Lime is mixed with filtered water in order to adjust the pH level and stabilize the naturally soft water so that corrosion in the distribution system plus the customers' plumbing will be reduced.
