Photographs from space show that our planet has more water than land. This gives us an image of a world with plenty of water sources, but only 2.5% of Earth’s water is fresh. 

Did you know that the water around us could be contaminated with deadly microorganisms? That leaves us with one choice: microbiological testing of water supplies. 

Water quality can be affected by a variety of factors such as contamination by microorganisms and other pollutants. This is caused due to poor water quality control and sanitation practices. The best way to ensure water safety is to conduct regular microbiological water testing.

At URS, we are eager to help you ensure the quality of water. As one of the leading water testing laboratories in Dubai, we understand how important it is to safeguard this precious resource. Our tests are conducted by professionals with deep knowledge in the field. We use sophisticated, state-of-the-art technology in our water testing laboratory.

Key Takeaway

• Environmental testing of water is an important factor to ensure water quality for safe consumption and use.
• Routine testing should be conducted to detect microorganisms in the water source and prevent any health risks associated with water contamination.
• Water Testing is done to identify the presence of bacteria and viruses such as Coliforms, Legionella, and other microorganisms.
• Efficient steps and control measures are to be taken to ensure the quality of water.

What is Microbiological Water Testing?

The testing of water is the most effective way to identify microorganisms in a water sample. Various tests and procedures have been developed for testing water quality. These tests are conducted at a water testing laboratory through standard policies and procedures. The testing of water is usually done by owners of water supply systems and commercial and industrial facilities. Private households can do water testing if they suspect water contamination.

The microorganisms tested in microbiological testing of your water include:

• Coliforms    
• E. Coli    
• Pseudomonas   
• Fecal Streptococci   
• Legionella SP

Water Testing Methods

The testing of water methods are offered for various water sources. These methods check for microorganisms present in the water. This helps to prevent any life-threatening diseases that could arise from contaminated water.

1. Coliform and indicator organisms

Coliforms are gram-negative, non-spore-forming rod-like bacteria that ferment lactose by producing gas at 35ºC or 44/44.5ºC within 48 hrs. It indicates the presence of enteric pathogens or viruses in the water. This makes the water unfit for human consumption. But, the presence of Coliform in itself does not state that the water is contaminated. Thus, further analysis has to be conducted to identify fecal coliforms. A few fecal coliforms include Enterobacter, Escherichia, and Klebsiella. The presence of E. Coli and Streptococci is also evidence of fecal contamination.

• Legionella Testing

Legionella is a pathogenic gram-negative bacteria that cause Legionellosis and Legionnaires’ disease. These microorganisms have a high chlorine tolerance. It occurs in plumbing lines and equipment if the water is not checked often. Legionella Testing is recommended to be conducted quarterly. This helps to prevent fatal diseases and ensure the quality of the water.

• Rapid methods

The Colilert Test uses proprietary Defined Substrate Technology (DST). This test detects both total coliforms and Escherichia coli, with results in 24 hours. It is approved by the U.S. EPA and included in Standard Methods for Examination of Water and Wastewater.

• Membrane Filtration

Membrane Filtration is a technique used to assess water quality. It is done through the use of a special filter called a Membrane filter. This filter is used to trap the microorganisms. This is an effective technique for the isolation and enumeration of microorganisms in the water sample. Thus, the MF method inspects both the quality of the water and the number of microorganisms in the water.

• Culture media

Culture media are mediums/sources that provide essential minerals and nutrients to microorganisms. This helps in their growth in laboratories. Culture media can be classified based on their consistency, composition, and application. They are used to isolate, identify, and study various pathogenic microorganisms. For example, membrane lauryl sulfate broth or agar are recommended media for coliforms and E. Coli.

• Other environmental water testing methods

A wide variety of our environmental water testing methods include temperature tests, pH testing, salinity tests, and metal testing, to name a few.

Pool water chemistry is important for both health and comfort.

The pH level should be between 7.2 and 7.8, the alkalinity level should be between 80 and 120 ppm (parts per million), and the chlorine level should be 1 to 3 ppm. These levels are ideal for swimming pool safety; if they are not maintained, you can experience skin irritation, eye irritation, dry skin, and dry hair.

When it comes to swimming, you want to make sure that your pool is safe and that you are protected from any potential harm. To ensure your safety and comfort, you should have a chemical test done on the water every week. This will help to make sure that there are no harmful chemicals in the water that could cause irritation or other health concerns for those who use the pool.

Maintain chemical levels

The pH of your pool should remain within the recommended range of 7.2 to 7.8, preferably close to the midpoint of the range. If your pH is too high, it may cause irritation and even burns in people with sensitive skin. If it’s too low, it can increase your risk of getting an eye infection or developing a rash.

An alkalinity level between 80 and 120 ppm is ideal. If this level is too high, it can cause corrosion on metal equipment and tile grout lines in your pool. Lowering alkalinity levels can be done by adding acid or soda ash (sodium bicarbonate) to your water supply.

Chlorine levels are determined by measuring how much chlorine is present in your pool water as compared to how much there was when you last balanced it out (added chlorine or removed it from your water). Chlorine levels should be 1-4 ppm for regular pools or 2-6 ppm for spas.

Chloramines (combined chlorine) are a byproduct of chlorination.

Chloramines are the combination of chlorine and ammonia, which occur when a pool is over-chlorinated. They are more difficult to break down than free chlorine and can be harmful if you come into contact with them. Water chemical testing in Dubai tests for these chemicals, and if the results come back positive, then you’ll need to neutralise the chemicals before you swim again. To eliminate chloramines from the water, use a combination of muriatic acid and baking soda.

Another indication is “chlorine odour” – each person has a different sense of smell and can respond differently to chlorine odour. A strong chlorine smell indicates that the chlorine level may be too high. The smell of chlorine is in fact chloramines, which are formed when chlorine mixes with ammonia and nitrogen-based compounds.

Protecting swimmers’ eyes/skin with goggles/protective creams is not considered proper maintenance.

It is important to know that protecting swimmers’ eyes and skin by wearing goggles or protective creams (i.e., zinc oxide) is not considered proper maintenance. These items merely protect the body from exposure to chlorine, but they do not treat the water itself.

Disinfectant residuals need to be maintained.

The most important aspect of pool safety is keeping the water clean, clear and safe from contaminants. The first step in this process is chlorinating your pool water. Chlorine is a strong oxidising agent that breaks up organic material and kills bacteria, algae and other microorganisms that may be present in the water. It also prevents them from growing back into larger colonies that could make you sick or kill you if they got into your system through an open wound or swallowed accidentally while swimming.

However, after the chlorine has done its job and broken down all these things into harmless byproducts, it needs to go away before it can cause any damage itself. This is done by adding algaecides and other chemicals designed specifically for removing chlorine from water so that it doesn’t cause corrosion of metal parts in your filtration system or other unintended side effects like burning eyes or skin irritation when you get out of the pool after a swim session.

Swimming Pool Water Maintenance and Treatment

A properly maintained pool will have lower concentrations of bromine, ammonia, methane, and other nitrogenous compounds than an improperly maintained pool. The presence of these chemicals in your pool can pose serious health risks to swimmers. A water test by URS testing and calibration laboratory in UAE will tell you if there are any chemicals in your water at all. A test for bacteria can tell you whether you need to disinfect your pool before anyone gets in it. If you’re having trouble with algae or slime on the walls of your pool, a test can help determine which chemicals are working best at killing it off.
