E.coli or Fecal coliforms count/100ml
What are fecal coliforms?
The fecal coliform is an organism that makes ATP by aerobic respiration if oxygen is present, rod-shaped, gram-negative, non-sporulating bacterium.
Where does faecal coliform comes from?
Faecal coliforms are bacteria generally originate in the intestines of warm-blooded animals and are then discharged into our water source.
Human sewage and faecal coliforms.
The wrong designed French drain or home septic systems can cause coliforms in the effluent to flow into the ground water that supply our boreholes with water. This is a mayor contamination factor that we find dealing with borehole water quality. Sewerage blockages that cause the sewerage to flow to the lower areas like rivers and lakes.
During the high rainfall seasons, the sewerage system can become overloaded and overflow in to a nearby stream or river.
Animals and fecal coliforms.
Animals like dogs and cattle and pigs, can contribute to fecal contamination of surface waters that seeps through the ground to the borehole water supply. Birds like swans, seagulls, geese, can be a significant source of fecal coliform bacteria in wetlands, lakes, ponds, and rivers.
Human health hazards due to faecal coliforms.
According to some authorities, large quantities of fecal coliform bacteria in water are not harmful to humans. The presence of fecal coliform may indicate a higher risk of pathogens being present in the water source. Some pathogenic diseases could coincide with fecal coliform contamination include ear infections, dysentery, typhoid fever, viral and bacterial gastroenteritis, and hepatitis A and more.
