Abstract:

Environmental indicators are necessary to enable decision making to be easier for organizations and provide a reliable basis of environmental information for the continuous improvement of different processes. Regarding the quality of water for human consumption, its characteristics can favor both the prevention and the transmission of disease-causing agents. Due to the importance of controlling this process, this research analyzed the operation indicators (turbidity, residual chlorine and pH) of the water pre-treatment process in a locality in the state of Veracruz, Mexico, using statistical process control through control of means and ranges. Environmental indicators’ behavior led to the knowledge that this process is affected by the quality of the water; this is variable especially, in the rainy season, when there is more turbidity due to the dragging of sediments towards the supply source, in addition to the existence of a relationship between the increase in the turbidity of raw water and the dosage of disinfectant used. Through a strict control placed on the incoming water, environmental indicators could be improved upon, which would favor the next step in its potabilization contributing to compliance of the current national regulations. Therefore, it is concluded that with the support of this statistical tool, corrective actions can be established to ensure water quality standards for human consumption.
