Copper (Cu), Zinc (Zn) and Cadmium (Cd) Contamination of Groundwater in Dikrong River Basin, Paumpare District, Arunachal Pradesh, India

Ground water pollution causes adverse damage to soil, plants, human and animals at the same time spreads serious diseases. Ground water pollution can also cause biochemical effects such as inhibition of enzymes, genetic damage, and hypertension etc due to higher concentration of trace metals in the ground water. The present investigation is directed towards analysis of major metal ion concentration in the Groundwater sources at the Dikrong River Basin. The study revealed that the level of Cu ranged between 0.01 ppm to 0.13 ppm, for Zn are in the range of 0.01 ppm to 0.13 ppm and for Cd it was from 0.001 ppm to 0.010 ppm. It was found that the levels of Cu were exceeding the standard BIS limits for drinking water at certain sampling stations.
