Preliminary tests conducted at nine locations last month revealed arsenic concentrations exceeding safety standards by up to 19 times in some samples. Further testing is being carried out in a laboratory to confirm these initial findings.

These findings will be shared with relevant agencies to implement appropriate corrective measures.
