There is often the mistaken view that water from borehole or some other natural source is safe and suitable for drinking. This view may be quite dangerous, but let's see why.
In the past few decades, in purely agricultural areas or where there was no coverage of a municipal water supply network, new boreholes were opened which, besides irrigation, covered the water supply needs of adjacent residential areas. But there are many areas where borehole s have been opened specifically for water supply or the local network is fed by a natural water source.
In the context of licensing a new borehole or legalization of an existing one, due by September 2014, chemical analysis has been done to check the particulate state and chemical composition of the water. This is a process necessary to verify the suitability of the water for the intended use.
Almost all boreholes use water filters but only cover the water filtration of stones, sand or mud so that the piping does not clog and the borehole mechanisms are destroyed. In later stages, when water is intended for watering animals or drinking water, reverse osmosis filters are used or disinfecting with chlorinating devices, but this is very rare, mainly due to high cost.
In any case, either the water quality has never been checked, the water has been classified as safe or special filters have been used, the quality of the water reaching our tap is determined by many factors, such as the situation in which the network is located , the maintenance of the borehole mechanisms and filters, and the condition of the aquifer that we draw from, which despite all controls can be influenced from day to day.
It is therefore necessary to ensure the quality of the water we consume using water filters, eliminating microbial organisms, hazardous metals and pesticides that may be present in our borehole water.
