Figure 21: Chemical Composition (NH 4 ,Fe,NO 2 , NO 3 , P and Mg) of Buyant Gol Water(near Jargalant)
in the Years 2004 (green line) and 2005 (blue line) between April and November of each year
(accord. to Meteorological SurveyStation Khovd)
The chemical composition of the river water measured by the Hydrological Survey Station of
the Khovd Branch of the Agricultural University of Mongolia (Figures 21 and 22) does not
show any inhomogenities or pollution, which hint to any water load.
25 water samples, taken in June 2006 during the field work, have been sorted from the
upstream part of Buyant Gol (in the first Mountain range of Altai Mountains) passing
Jargalant and then mainly taken from the projected areas. The last three samples (23 -25)
have been taken from the sewage channel, which leads from the Jargalant sewage plant to the
Buyant Gol. Here the water is hyper polluted, however, a lot of it is seeping into the
