Contaminants are chemicals that contaminate water and make it unsafe to drink. The taste, odor, and turbidity of the water can all be used to identify certain toxins. Most, on the other hand, are difficult to notice and need testing to determine whether or not water is polluted. Contaminants in water may cause a slew of illnesses that have a devastating impact on human health if left unchecked.
Contaminants are either man-made or naturally occurring. Some contaminants are organisms that include pathogens like bacteria, viruses, and parasites such as microscopic protozoa and worms. These living organisms can be spread by human and animal waste. Good sanitation and hygiene can help to stop the spread of these organisms.
Man-made byproducts of industry and agriculture, such as heavy metals like lead and mercury, as well as toxic chemicals and compounds like pesticides and fertilizers, are the most common man-made water pollutants.
Water can also be contaminated by naturally occurring elements. Toxins like arsenic, a very deadly element, may be naturally present at dangerous quantities.
Before it may be utilized for human consumption, contaminated water must be treated. Water treatment can take place in two locations: a centralized water treatment plant or at the point of usage.
Purification of drinking water is done using a variety of technologies. Treatment technologies are chosen and implemented based on a number of criteria, including the source of the water, the kind of contamination, and the cost.
A mix of technologies is employed to ensure that water is properly decontaminated for the most effective treatment.
