Graded IV) fail to meet manganese standard, while the other five reach Grade I; two
fail to meet the standards for ammonia nitrogen, iron and aluminum; and one fails
to meet the standards for TDS, nickel, sodium and chloride. In terms of the
remaining 21 indicators, all sample groups are up to standard and classified into
Grade I.
According to the integrated results (Table 5.26), seven of the nine sample groups
are classified into Grade V, including ZK1, ZK2, ZK3, ZK4, ZK5, ZK6 and MJ8.
