And the impact on the groundwater was also analysed. You can see here the pH. Upstream is 7.72, whereas in the downstream it is point 6.74. And the TDS in the upstream is about 890 milligrams per litre, which has increased to 2.310 milligrams per litre in the downstream.
Similarly Calcium, Magnesium, Sodium, Potassium and Chlorides have increased in the groundwater also, except the Fluoride, which is 1.75 in the upstream has reduced to 1 in the downstream.
