Compare with average

From now, we can conclude Kohsoom, Tansanee may have potential risk of pollution, due the values changes recently. But Tansanee collection data is not sufficient to confirm as it is only from 2009. And there are also interesting valuables such as water temperature implied the place is in north part of earth, because of June, July high temperature. For those dropping readings, that may be changed from climate or human activities. We may need to collect more data to fill in all gaps to find out other evidence.

Insights	Visualization
1. Rising values: Ammonium, Anionic active surfactants, Chemical Oxygen Demand(Cr), AOX, Bicarbonates, Magnesium, Magnesium, Sulphates, Total hardness Recent Period (from 2014 to 2016) In the recent years, Ammonium, Anionic active surfactants, Chemical Oxygen Demand(Cr) ,AOX, Bicarbonates, Magnesium, Magnesium, Sulphates, Total hardness are abnormal volatility during the past three year. Specially, in Kohsoom and Tansanee, there is obvious upper stream for those values. While, Tansanee has the above the average reading values with most of valuables.
2. Decreasing values: Gamma-Hexachorocyclohexane, Cadmium, Chlorides, Chlorodinine There are some types of values with decreasing trend. For gamma-Hexachlorocyclohexane,Clorodinine, the readings are decreasing along with all places, thus we can conclude it is happened overall area.
