1.Heat map (1) For the Arsenic, we can see at the beginning, it’s 0 and with time goes by, it’s increasing. (2) For Atrazine, it’s increasing at the beginning and 2006-2010,reach the high point, then decline, recently 0. (3) Biocarbonates and biochemical oxygen although they are changing, but they change slightly, relatively steady. (4) Cadmium value is high in the past but recently, it’s decline. (5) For Chloridinines, we can see it’s high in 2014 and 2015, and very low in 2016. (6) Chromium and copper value is decreasing steadily. (7) Dissolved oxygen is increasing steadily. (8) Although fluoranthene data is not sufficient, we can see the increasing trend. (9) The value of gamma-hexachlorocyclohexane is amazingly all zero in recent years. (10) Methylosmoline value is extremely high in 2016 and increasing from 2014-2016. (11) DDD,DDE and DDT is higher is past, and almost none recently, which shows we used to use DDD and so on to kill the pest. Now we no longer use it. (12) PCB is increasing. (13) pentroleum hydrocarbons is extremely high in 2012 and the other years, low. (14) Water temperature is increasing steadily. (15) In 2016 zinc is very low.	Heat map [1]:
2.Changing with the location? From the Heat map, Chloridinines and Methylosmoline seems to change sharps in the most recent years, to further explore it with the location, add the location to see in different location, whether the measure value is different. For Chloridinines:In Chai, it drop steeply and in Kannika and Sakda, it drop slowly then drop steeply, and in Busarakhan and Somchair, it’s more or less the same trend, and in Boonsri and Kohsoom, 2014 value is higher lower than 2015, then both drop sharply. They both reached the low point in 2016. For Methylosmoline:In Boonsri, Busarakhan, Kannika and Sakda, the value is very small, but in Chai, 2015, the value is higher, and for Kohsoom and Somchair , it sharply increased in 2016.

3.Geo map Now we see some contaminant is different with region, so we want to do a map to show it more directly. For Chloridinine, as we can see, we don’t have recorded data in Achara, Decha and Tansanee. In other places, we can see that in 2014 and 2015, Chlorodinine is relatively evenly distributed in all the places, but in 2016, only Kohsoom increased, the other places all declined. For Methylosmoline, Methylosmoline only sharply increased in Kohsoom and Somchair from 2014 to 2016.	Chloridinine [4]: Methylosmoline [5]:
