A recent investigation by the National Water Laboratory shows that as many as 370 community water systems in Costa Rica are contaminated by microbiological matter. It had already been reported that some 24 communities’ water supply systems had arsenic contamination.
The report also indicates that in addition to microbiological matter, the water systems are also contaminated by high amounts of iron and calcium, agrochemicals, grey water, and hydrocarbons. Many of the water systems say that they have never received any instruction from the Costa Rican Institute of Aqueducts and Sewers (AyA) on how to properly treat the water. This is clearly a very concerning issue considering the many potential diseases that can come from arsenic and other types of water contamination.
