Analysis of Water Quality Change before and after the Wenchuan Earthquake

Abstract:

“5.12 Wenchuan earthquake”triggered floods, landslide, collapse and secondary geological disaster, trigger a new soil and water loss, having the significant influence to the local river water quality.This article through the statistical analysis of minjiang river and jiangyou wenchuan, beichuan station 2006 ~ 2011 water conditions material, discussing the before and after the earthquake disaster areas of river water quality change characteristics. The results showed that the affected areas of ammonia nitrogen content after the earthquake are more than before the earthquake content .The fluoride content before earthquake overtop that after earthquake in Wenchuan water source .The total hardness of water quality presents upward trend in disaster area after earthquake, and the total hardness of water quality in 2010 and 2011 is greater then that before earthquake. The total iron content is not affected by the earthquake, before and after the earthquake did not appear obvious difference.
