Conclusion

Q1: Characterize the past and most recent situation with respect to chemical contamination in the Boonsong Lekagul waterways.

Img 1: % yearly change of pollutants value

As observed in Img 1, there appears to be no obvious trends in terms of % yearly change of pollutants value. There is no consistent increase or decrease over the years as observed from the mix of red and green cells across the years. However, it appears there to be sharp increase and decrease in terms of pollutant values as observed from the bright green or red respectively. Further analysis is done for each pollutant that has sharp changes in recent years (2015 & 2016) to understand the location that has contributed to these changes.
