The planners of Malaysia have been trying to coming up with models that indicate the amount of pollutants has grown over time as cities became more industrialized and how these chemicals are distributed in various regions with the usage of econometrics and various scientific tools. Such an attempt is encourages in-depth researches because sources should be able to analyzed numerically and give economic evaluations while also evaluating the environment. With abundance of evidences provided by models which reveal the inadequacy of current policies, the Malaysian decisions-makers now recognize that appropriate treatments are necessary in regions that are industrialized to protect the residents from water pollutants.
