Dear Mr. Chaudhary, 
On 3rd January 2019 I sampled the water from 2 boreholes on land owned and occupied by APEC Kolath. These samples were sent to the Tara Laboratory in New Delhi for analysis. 

I have now received the laboratory reports from the analysis and can confirm the presence of contaminants in both water samples. These are all above the legal limits imposed by the Ministry of Water Resources in the Water (Prevention and Control of Pollution) Act, 1974. The contaminants are detailed below.
