Question 1
Characterize the past and most recent situation with respect to chemical contamination in the Boonsong Lekagul waterways. Do you see any trends of possible interest in this investigation?
Increasing trend in arsenic levels
Arsenic levels in the waterways have been below 10 µg/l (i.e. the safe limits prescribed by United States Environmental Protection Agency). However, there has been increasing trend in arsenic levels for a few areas. Tansanee has seen its arsenic levels increase from 2.26 µg/l (2011) to 4.468 µg/l (2015). If this trend continues, the arsenic levels might cause the waters not to be safe for consumption.
