Possible Hidden Contaminants That Might Be Present In Your Water

Possible Hidden Contaminants That Might Be Present In Your Water

Many do not stop to think of the quality of water that they are consuming, and credit is also given to Singapore – where we are fortunate to have clean and drinkable tap water given to us.

However, it is important to remember that water given to us can still be contaminated.

You can’t be too careful when it comes to your health, so while the filtration systems are successful, you can’t be certain what will happen between the plants and your tap.

Here are a few of potentially hazardous chemicals that might and can be present in your water.


Summary of contaminants:

  • Rust
  • Aluminium
  • Uranium
  • Fluoride
  • Lead
  • Chlorine
  • Bacteria and Viruses
  • Others



Rust is an iron oxide that forms when iron is exposed to air for extended periods of time. The reddish-brown material commonly enters your drinking water via corroded iron pipes or water mains. Rust’s major disadvantage is that it gives water a metallic, unpleasant flavour and odour. You don’t want to drink it after washing your veggies.

Water containing high amounts of rust (iron) can bring on a number of dangerous side effects, but it is improbable that enough rust would be present in water to be harmful to one’s health. Rust, on the other hand, may indicate a leaking pipe that has been exposed to various forms of contamination.



Under certain conditions, aluminum may be leached from rock and soil to enter any water source. Al3+ is found in groundwater at concentrations ranging from 0.1 to 8.0 ppm, according to some studies.

Water treatment is not an inexpensive process, and salt regeneration adds extra time to the already lengthy rinse cycle. Alumina is readily removed by cation exchange resins such as those used in water softeners, but it is not readily removed back off the resin with normal salt regeneration. Periodic acid treatments are required to remove accumulated aluminum from the resin.



Uranium is a common, naturally occurring and radioactive element. It may be found in rocks, soil, air, and water as a component of minerals in nature – but never as a metal.

Uranium is introduced into water by soil and rock leaching or emissions from processing plants.

The anionic complexes, UO2(CO3)2 -2 and UO2(CO3)3 -4 , which contain uranium in water, are found in natural waters.



The addition of fluoride to public drinking water supplies at about one mg/L (as fluor) in the form of a salt, for the objective of preventing tooth decay is perhaps the most recognized application.

It’s the fluoride ion in mineral ionic form that you get from drinking water, bones, teeth, and public water supplies.

To comply with safe drinking water regulations, certain water systems that have naturally occurring fluoride must filter their tap water to eliminate the extra fluoride.

Children under the age of nine who are exposed to fluoride levels higher than about two mg/L might acquire mottling or discoloration of their permanent teeth.



Lead is a toxic metal with severe health effects in even small doses, despite its prevalence. While uncommon in Singapore, even minor amounts of lead can accumulate in your body over time and cause serious illnesses.

Weight loss and stomach discomfort are common symptoms of light poisoning, while brain and kidney damage may occur in the most severe instances.

Lead is one of the most toxic pollutants on the market. It may be absorbed by both adults and children, with children absorbing far more lead than adults despite their smaller size. Even with small doses of lead, youngsters have been found to have problems including stunned learning, short stature, and poor hearing.

Acetone is a hazardous substance that should not be consumed in drinking water.



Chlorine is a naturally occurring gas or liquid that is commonly used to disinfect water. Although it is usually harmless at low doses, water treatment plants keep an eye on chlorine levels to make sure they are within acceptable limits.

Even though chlorine water may not have an unpleasant odor, it can still give off a chemical or bleach-like scent. Excess chlorination also increases the risk of asthma attacks and other long-term health concerns, especially in children.


Bacteria and viruses

Bacteria, viruses, and cysts can all thrive in water. While some are harmless, others may cause disease, such as the notorious E. coli. E. coli infection might produce a variety of unpleasant symptoms, including stomach cramps, vomiting, diarrhoea, and other conditions.

The presence and types of germs in your drinking water will influence the risk of disease, but any hazard is undesirable when it comes to consuming water.


Others (not as commonly found)

Other waterborne contaminants include:

  • Arsenic
  • Barium
  • Cadmium
  • Chloramine
  • Copper
  • Nitrates/Nitrites
  • Mercury
  • Silver


All in all, the quality of your drinking water is important for the health of you and your family. Luckily, there are a number of filtration options available to help keep your water clean and safe.

Puricare offers water dispensers in Singapore that are compact, with high quality filtration systems, and with other advanced features to meet your home or office needs.
