Xylenes drinking water contamination

Under the Safe Drinking Water Act, the maximum contaminant level (MCE) is the standard criterion for drinking water and the maximum contaminant level goal (MCLG) is the ideal. The proposed MCE and the MCLG for mixed xylenes are both lOmgM. ...

In the US EPA Primary Drinking Water Regulations, maximum contamination levels (MCLs) were established for several compounds (for instance 0.2 xg/L for l,2-dibromo-3-chloropropene 5 trg/L for benzene, carbon tetrachloride, 1,2-dichloroethane, trichloroethylene, and tetrachloroethylene 1 xg/L for toluene 0.7 xg/L for ethylbenzene 10 xg/L for total xylenes and 2 JLg/L for vinyl chloride) [44]. The main apolar and polar DBPs, THMs, and haloacetic acids are regulated under Stage 1 and Stage 2 D/DBP rules by US EPA [30].
