In this diagram (Fig. 15), water samples are divided in three zones namely good, acceptable and unsuitable zones according to desirable and permissible limits of the parameter (WHO 2011) for drinking water.
Figure 10 clearly indicates that the high EC values of the groundwater samples were lie in the moderate-to-unsuitable zone, except in a few places.
According to WQI classification, 45% fall in good water zones, 50% of the samples fall in poor water zones and 5% water samples fall in very poor water zones in post monsoon period, while in pre monsoon 40% samples fall in good water zones, 45% fall in poor water zones, 10% fall in very poor water zones and 5% fall in unsuitable for drinking zones (Table 5).
Almost 450 ha of residential and public land was designated as a 'Red Zone' unsuitable for residential redevelopment because land damage was so significant, engineering solutions were uncertain, and repairs would be protracted.
SE of the first kind caused by controlled seismic impact can be applied in engineering geology as a marker of unstable zones unsuitable for building.
Higher concentrations of TDS, HCO( _{3}^ ), Cl− and SO( _{4}^{2 - } ) in all zones render it unsuitable for industry too.
In parallel, however, the alternative pathway activity of the leaves increased (Gandin et al., 2009), rendering hypothesis (2) unsuitable for explaining the increased root-zone gas exchange in combination with unaffected shoot dark respiration.
The study observed that phumdis have nutritional potential as feed material due to its higher crude fibre and crude protein content, but the inorganic content in the root and mat zone was found to be unsuitable for the purpose.
For T. karelinii, the northwestern part of the current introgression zone is predicted to be unsuitable currently, but also in the two past time periods.
