Risk of coliform infection in water

Coliform bacteria are bacteria that can inhabit many different environments such as soil, water and also the human digestive system. This is the culprit for many dangerous diseases on the digestive system such as diarrhea, dehydration leading to kidney failure, even death.

1. What is Coliform bacteria?

Coliform is an anemic, rod-shaped and spores-free gram-negative bacterium. Coliform bacteria are capable of fermenting lactose accompanied by vapor, acid and aldehyde production within 24-48 hours.

This type of bacteria can exist in many different environments such as soil, water (domestic water, drinking water, aquaculture water), in animal feed and waste. Humans rely on the amount of Coliform and E.coli in the water to assess the level of water pollution.

The national technical regulation on the content of Coliform bacteria in the country is as follows:

  • In drinking water (QCVN 01:2009/BYT): Total coliform content is 0 bacteria/100ml;
  • Domestic water (QCVN 02:2009/BYT): Total allowed coliform content is 50 bacteria/100ml;
  • In industrial wastewater (QCVN 40:2011/BTNMT): The allowed coliform content is 3000 mg/l for wastewater of type A and 5000 mg/l for wastewater of type B.

2. Manifestations when the body is infected with Coliform bacteria

The incubation process after Coliform infection is usually 3-4 days. By the time of the onsentness, the patient will have unclear symptoms such as: Mild diarrhea, intermittent diarrhea, fatigue, fever,… Symptoms of nons specific diseases should be easily confused with other diseases.

3. Harm of Coliform bacteria

Coliform can cause disorders that cause dehydration, blood disorders, kidney failure or even death. The dangers of this type of bacteria are even more serious in the elderly and children because these are subjects with weak resistance. Meanwhile, the symptoms of the disease are often unclear, mainly diarrhea and fever, so patients often subjectively ignore. This misses the opportunity to treat the disease in a timely manner from an early stage.

4. Causes of Coliform bacteria that exist in water

The causes of the appearance of Coliform bacteria in the country include:

  • Improper disposal of domestic waste, industrial waste and animal feces, improper standard procedures, causing waste containing Coliform bacteria to penetrate the ground, seep into groundwater circuits and cause water sources to become contaminated with Coliform;
  • Domestic water treatment plants have not thoroughly treated Coliform bacteria;
  • The well water source is not treated because the main well water supply is groundwater circuits that have been infused with Coliform bacteria;
  • Machine water contaminated with Coliform due to flowing through old pipes, rusted due to too long use;
  • Ermed rainwater.

5. Measures to detect Coliform bacteria in the country

  • Check the bacterial content in the water every 6 months;
  • Check the content of chemicals in the country every 2 years;
  • Check more often if domestic water has changes in color or taste.

Note when using a water purifier

It is recommended to check the water regularly every 6 months

6. Prevention of Coliform infections in domestic water

  • It is recommended to check the water regularly to detect the existence of Coliform.
  • If well water and groundwater are contaminated with Coliform bacteria with excess content, filtration technologies should be used to purify water completely. RO filtration and Nano filtration technologies are the right choice.
  • Disinfecting domestic water with Chlorine, ultraviolet rays;
  • Drink only boiled water to cool.

The risk of coliform infection in water is very high. therefore, to ensure the safety of ourselves and our families, we should carry out cooked meals, drink boiling and regularly check the quality of water. If there are warning symptoms of Coliform infection such as diarrhea, fever, dehydration,… should immediately go to the doctor for timely diagnosis and treatment.
