摘要：The groundwater pollution is an increasingly serious problem in the world. There are abundant coal resourcesand coalbed methane resources in Sanjiao area, Hedong Coalfield. The exploitation of mineral resourceshas a pernicious influence on the local groundwater environment. The local shallow groundwater is the onlydrinking water source for local residents. So the analysis of the groundwater pollution characteristics isessential for maintaining drinking water safe for local residents. The results showed that NH 4 + , Cl - , SO 4 2- ,NO 3 - , F - , NO 2- , Cr 6+ , Fe, TDS, etc. have exceeded to varying degrees. The amount of methane in SX99 isvery high, so it should take measures to release methane to reduce the methane concentration in groundwater.
