0.22 mg/L), and 0.02–0.88 mg/L (with an average of 0.29 mg/L) respectively. The
excess rate in descending order was 44.00% (Mn), 22.22% (Al), 22.22% (Fe),
11.11% (Ni) and 11.11% (Ba). Excessive Mn was found in ZK1, ZK4, ZK5, and
especially ZK6 where the concentration attained 8.80 times of the limit. Al
exceeded the limit in ZK2 and ZK6 and Fe in ZK1 and ZK6, and the highest
concentration was both observed in ZK6, representing 1.45 and 3.73 times of the
standard values respectively. Ni and Ba was beyond the limits in ZK2 only, with the
content reaching 1.63 and 1.35 times of the standard values respectively. All these
imply serious groundwater contamination.
• Halides
As shown in Table 5.24, the halides detected in groundwater samples include 1,
2-dichloropropane and 1,1,2-trichloroethane. They were only detected in ZK4 and
ZK5, which represented 22.22 and 11.11% of the total sampling sites. According to
the Quality Standards for Groundwater (GB/T14848–2017), there is no excess of
halides as the concentrations are lower than the standard value (5 lg/L).

excess rate in descending order was 44.00% (Mn), 22.22% (Al), 22.22% (Fe),

especially ZK6 where the concentration attained 8.80 times of the limit. Al
exceeded the limit in ZK2 and ZK6 and Fe in ZK1 and ZK6, and the highest
