Red values are those that do not meet the water quality criteria Objective for the specified parameter. The Objective is a Water Quality Index that helps to
identify the environmental health condition of a water body. Objective values are either minimum or maximum goals to be aimed as a water quality criterion
for the SJBEP. Some of these objectives were obtained after evaluating a year of water quality data.
