Fervença river water quality evaluation – water quality index (WQI)

, 2022
Water is fundamental for the survival of every specie on planet Earth and is a crucial element of the environment. Water bodies, however, have degraded over time due to various natural and mainly human-polluting activities. As a result, water quality control is required to monitor and reduce polluting agents while maintaining river health. The adoption
