Pharmaceuticals in the water?

When a person requires a water purification system for domestic or commercial use that is going to be used for human consumption, the ideal is to let us know the origin of it, and the results of the analysis of the most important parameters of potability (such as those indicated in the NOM-127-SSA1-1994 standard), determined by an accredited laboratory. With this information we can suggest the simplest purification system that guarantees the potability of the treated water.

Some contaminants, such as chlorine, can be removed with a very simple activated carbon scrubber, but other contaminants, such as nitrates, fluorides, arsenic, and metals, require a more comprehensive treatment system.

If the source of water is a lake or river and if there are populations near it, the water will most likely contain numerous pollutants that are harmful to health.

In recent years, concerns have arisen about the presence of drugs or pharmaceuticals in the water, which for some reason may reach the groundwater table or surface water bodies. This is mentioned in the WHO technical report which is summarized in the article in the following link:
Although the report mentions that drug levels in drinking water are often low to affect human health, a number of researchers have found that these (parts per billion) can seriously affect human cells. In fact, as the article mentions, there are a large number of substances that affect human health in very low doses.
For all the above, the technology that we recommend to guarantee the potability of the water is reverse osmosis. Above all, if there are children, the elderly or people with immune problems in the house.
