What To Do In Case of Water Contamination

Contaminated water can present different sorts of problem. Some substances can make the drinking water harmful to health. Other non-threatening contaminants can affect the palatability of the water or lead to technical consequences. Knowing what do in case of water contamination is very important. Installing a water filter or performing a water analysis is not the only way deal with the threat of contamination.

In a situation where there is a suspected water contamination problem, the first step is to identify the public water system that supplies the water. The name of the supplier should be present on the water bill. Those who are renting homes or apartments and do not pay the water bill can ask their building managers or landlords regarding the water supplier. Another option is to contact the local health department which should be able to provide this important information.

Report the problem with the water to the public water company. All water suppliers have people or a department that deals with problem reports and inquiries. If the company is unresponsive, the local health department can be contacted instead.

In the case of private well users, it is their responsibility to have water analysis performed to identify the type and cause of the problem. A contamination caused by nearby human activity must be reported to government health and safety agencies so that the liable party can take responsibility of the problem.

Common Causes of Water Contamination

Contamination of water by germs or dangerous chemicals is a very serious issue that require immediate action. A common sign of water contamination is the change in color, flavor and odor of the water. A change in any of these properties is enough reason to report the issue to local health agency, environmental department or water supplier.

In order to address the problem of water contamination, the first step is to determine the cause or mode of contamination. A water sample will have to be collected and tested. The result of the analysis of water will provide valuable information that will be used for determining the cause of the problem.

There are several common causes of water contamination. The first one is referred to as natural contamination in which natural-occurring minerals and substances get into the water.  This is mainly due to melted snow, rain and flood water percolating through the soil and dissolving minerals and taking it to the water table or surface waters.

The second one is agricultural practices such as farming and livestock raising. Chemicals like pesticides and fertilizers are applied to the soil which can then be carried off to water supply sources similar to the naturally-occurring minerals and substances.

Improperly disposed waste and byproducts from factories is the third cause of water contamination. Some factories store their waste and byproducts in drums that can leak into the soil and penetrate to reach underground water. Other factories throw their waste in rivers and streams. These practices are illegal but some risk breaking the law and getting caught to reduce the cost related to proper waste disposal.

Questions And Answers About Ultraviolet Water Filter Systems

Whenever you purchase an ultraviolet water purification system you should know that has been designed in such a way as to protect your drinking water from the occasional intrusion of microbiological contamination. These filters are becoming a lot more popular today than ever before. This is whya lot of people have a lot of questions about these filters.

Answers To Your Questions About Using An Ultraviolet Water Filter

There are some very common questions that people ask whenever they are thinking about purchasing an ultraviolet water filter. These questions include:

Are any chemicals required by this system? Or is there anything else that I will need to add?: It is recommended by most manufacturers that you use a 5 micron sediment filter because large particles act as a haven for microorganisms, which is what you are trying to destroy.

Sometimes multiple sediment filters are required because of the water's turbidity. This is because color and suspended particles will diminish the transmission quality of any UV light. In these cases, a quality carbon filter is used to filter the sediment first.

Should I do anything before I install an ultraviolet water filter system?: You should make sure that your system (water lines, water heater, etc.) is clean first. In order to do this, you should disinfect the entire downstream system with chlorine.

How long does the UV bulb last?: You will need to replace the ultraviolet light bulb once every 10 to 12 months. While the bulb will last a lot longer then that, its capacity for neutralizing microbes will be diminished after this length of time and so you will want to make sure that it is changed at this point so that it can work as effectively as possible.

Why is the water cloudy/white after a new filter cartridge is installed?: This is because the water needs to be ran for a few minutes once a new ultraviolet water filter cartridge is installed. The water's cloudiness indicates that there is air in your line, housing and cartridge. This is normal whenever you replace a cartridge.

After you run the water for a few minutes the cloudy conditions will go away unless your water is VERY cold. In this case the oxygen in the water is what is making your water look cloudy. Either way, it is always a good idea to run the water for a few minutes after you install a new filter cartridge.

Harmful Effects of Scale Buildup

Scale is the solid chalky buildups inside of pipes, boilers, tanks and kettles and it is because of hard water. Hard water is found in places with rich deposits of minerals underground. As water seep into the ground it carries the minerals such as calcium and magnesium with it. Scale buildups are primarily made of these two mineral contaminants. A scale filter is used to prevent the formation of calcium and magnesium deposit inside pipes, tanks and other water storage and delivery components.

Calcium and magnesium are contaminants that are non-threatening to health. However, the scale buildup caused by these two minerals can be quite problematic in the industrial setting. Scale buildup inside a heating pipe limits both liquid flow through the pipe and ability to transfer heat from the liquid to the outer pipe shell. In effect, the overall thermal efficiency of the pipe when used as a heat exchanger is reduced.

Pipe bursts and leaks are other problems caused by scale buildup. The scale effectively reduces the inner diameter of the pipe and limits the amount of water that can flow through it. This causes increased pressure in the entire plumbing. The pressure can lead to leaks or bursting pipes.

The deposit can break off into pieces. These broken off pieces can get carried to other parts of the equipment where it can interfere with water flow or get pinched in moving components which can lead to equipment failure.

Any task that involves using of detergent is affected by hard water. The minerals in hard water make it difficult for detergent to lather. That means more detergent is needed which increases the cost of operation.

Presence of Dichloromethane in Water

One of the greatest source of water problems are human practices and activities. Agricultural and industrial practices that support the modern world produce byproducts or use substances that can be harmful to the environment. These harmful substances can easily get to bodies of water that serve as a source for countless households.

Water contamination is a serious problem that requires action. However, it is simply not possible to eliminate the threat of contamination entirely. The only way to eliminate this threat is by stopping the aforementioned industries and there is just no way that is possible. What can be done, is to minimize the risk of such contaminations. Water analysis and treatment is important to protect yourselves from the threat for water contamination.

It is also very important to learn about the potential contaminants that can compromise the safety of your water.

Dichloromethane is a colorless volatile organic liquid that gives off a sweet pleasant odor. It has plenty of different applications but is primarily used as a paint remover. Also known for its acronym DCM, this liquid compound is also used as a solvent and cleaning agent in various industrial operations.

The presence of dichloromethane in water has been linked to cancer and liver problems. Private wells that are located near operations and other human activities that use DCM such as drug and chemical companies have higher chances of contamination. In order to protect the safety of the people relying on the private well, a regular water analysis must be contacted to keep track of the quality of the water.

DCM can removed from the water through granular activated carbon water treatment and packed tower aeration.

Purification of Water

Water can contain unwanted contaminants. Purification of water removes contaminants that can affect the usability of the water. Purification of water is often associated only with the installation of filtration systems. However, there is more to it than that. In fact, it is similar to how doctors treat diseases. Before prescribing medication, the condition must first be diagnosed.

In the purification of water, it all starts with water sample testing and risk analysis to help predict or diagnose the water problem. A water sample is sent to a laboratory to be analyzed for presence of contaminants and checked for quality indicators. Water quality indicators include pH levels and presence of fecal and total coliforms.

Risk analysis involves investigation of human activities and geological conditions nearby that can have an effect on the water source. Mining, manufacturing and agriculture are some examples of human activities that can lead to contamination of water sources. Improperly disposed waste and byproducts used in these activities can sip through the soil and lead to underground water or get carried off by water from the rain or melted snow into rivers, lakes and other bodies of water.

By knowing potential and actual water problems, it is now possible to identify the ideal water filtration system to install. There are plenty of types of filtration systems that feature treatment processes that are designed to deal with certain types of contaminants.

Home water filter systems are popular amongst those who have private wells. The filter system not only keeps the water safe but also improves its taste. Some households also use filter systems for public water sources to remove the disinfectants that are added in the water by water suppliers.
