Water filtration processes like reverse osmosis were developed because of one simple yet great reason: drinking unclean water can be life-threatening. There’s a myriad of contaminants lurking in any water source, most of which cannot be seen in plain sight. Here are a few of them.
Bacteria – It’s fair to say that any untreated water source harbors H2O that’s ripe with bacteria. When a water test indicates high bacterial concentrations, the water is considered completely unsafe to drink until the problem is fixed. Various factors like spring runoff, heavy rain, or even prolonged dry spells can adversely affect water quality over time.
Arsenic – Drinking water with arsenic levels way above the EPA’s safety standard can cause a wide variety of health problems, including damage to the lungs, bladder, heart, kidney, and liver. It has also been found that arsenic exposure is linked to several types of cancers.
Dissolved gases – Gases like oxygen, carbon dioxide, nitrogen, radon, methane, and hydrogen sulfide can dissolve in water; though only hydrogen sulfide and radon can cause health complications.
E. Coli – E. coli bacteria live only in animal intestines, as well as that of humans. If high concentrations of E. coli bacteria are present in a water source, it means that the water is contaminated by feces, making it unfit for consumption.
With all the potential dangers that may be present in water, it’s safe to say that effective water filtration systems and methods, such as reverse osmosis, are valuable in today’s society.
