The presence of pharmaceuticals in water supplies is a growing concern worldwide. Medicines have been found in the drinking water supplies of about 41 million Americans. The concentrations of these medications are very small and will likely not impact anyone

How does this happen?

Medicines get into the water supply by human excretion, drugs being flushed down the toilet or going down the sink. The disposal of unused or expired medications by flushing them down the toilet or pouring them down the sink contributes to pharmaceutical contamination of water supplies. The wastewater is treated before it is released into water but pharmaceuticals can pass through water treatments.

The effect on humans

There is no evidence showing that the drugs in the water supply are affecting humans, the presence of the medication is extremely low. While the focus has primarily been on human health impacts, the presence of pharmaceuticals in water supplies can also have ecological consequences.

Effects on ecosystem

Aquatic organisms living in contaminated water bodies may be exposed to these substances, leading to bioaccumulation and potential disruptions to aquatic ecosystems. As predators consume prey that have accumulated pharmaceuticals, the concentrations of these substances can become magnified, leading to potentially harmful levels in top predators.

Possible solutions

Increasing public awareness about the pharmaceuticals in the water supply and promoting responsible medication disposal methods can help prevent the improper disposal of medications and upgrading wastewater treatment will clean out all medicines and other waste that is in water
