A total of 290 water for livestock and 111 wastewater samples were collected in two years 2019-2020. The result of testing water for livestock showed that 100% of samples met the allowable requirements for nitrite, TS, copper, zinc, cyanide, lead, mercury and cadmium criteria
0.34-26.52% of the samples did not meet the allowable requirements for other indicators, in which different samples were recorded with the results of iron and manganese indicators having the detected content at 5.0 times higher the allowable limit of the standard, the total Coliforms index was 153 times higher the maximum allowable limit of the standard, in particular, 48 samples of water were contaminated with Fecal Coliforms. The results of testing livestock wastewater indicated that there were 100% of samples met the allowable requirements for arsenic, mercury, lead, cadmium
1.80 - 65.77% of samples did not meet the allowable requirements for other indicators, in which the different samples having total phosphorus at 5.42 times higher, TSS at 7.75 times higher, total nitrogen at 29.61 times higher, ammonium at 35.44 times higher, COD at 86.24 times higher, BOD at 105.64 times higher and Coliforms indicator at 220 times higher than the maximum allowable limit of the regulation were noted.
