Importance of the use of environmental indicators in the water pre-treatment process of a case
study in Veracruz, Mexico

Environmental indicators are necessary to enable decision
making tobeeasier fororganizations andprovidea 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.
