1. Hight levels of Methylosmoline detected ” There’s a sharp increase in Methylosmoline levels in 2016 in both Kohsoom and Somchair. Averages increase sharply in the 4 quarters of 2016. This is of particular concern because it’s the contaminant agent. This requires more investigation. In all samples of Methylosmoline for all quarters the measurement is of 130 approx for Somchair and 50 for Kohsoom. This is considerably higher than the average of 22.32 in Kohsoom and 53.50 in Somchair for the last 3 years.
2.Water temperature has been increasing Water temperature is cyclical and warmer in the months from June to September (summer). However, in 2016 there’s a higher average water temperature in all locations. To be specific, in 1998 the average water temperature in all locations was 12.95 degrees. While in 2013 is 13.89, in 2014 is 14.79, in 2015 is 14.09 and in 2016 is 14.74 degrees. Global warming and other external causes can obviously affect this measurement, however, it’s worth exploring further..
3.There's been drastic changes in Sulfates We can see a clear trend in the years after 2007 until 2012 when the average measurement for Sulphates is lower for all locations. But specifically in Kohsoom , Somchair and Busarakhan.
4.Other chemical changes TLooking at Arsenic, Iron and Aluminium, we can determine there’s a huge release of these heavy metals: Arsenic in 2009 for all locations and specifically in 2010 for Kohsoom. Aluminium in Q2 2009. Iron in Q3 2003. Phosphorus peaks in different locations in 2006, 2009, 2014. This is a clear sign of drastic changes in soil or water. It's worth investigating all chemical changes.
