Valuation of water quality for livestock and poultry watering: a case study of groundwater in some areas of Mosul city, Iraq

Present study aimed to assess the quality of groundwater for livestock and poultry watering in some areas of the left side of Mosul city, and give a clear picture of the degree of pollution of these water sources, where samples are collected randomly from 11 wells (five replicates per well), to measure the physical, chemical and bacteriological properties using the subindex model with the use of international standards for the permitted levels of livestock and poultry watering , as a result of the impact of water quality on the productivity of meat, milk and eggs and thus affect the national economy. The results indicated that 55% of the studied water samples of good water quality category, while 36% of the samples of poor quality, this deterioration in quality is mainly due to the high number of TPC and faecal coliform bacteria which reached (15 × 10) cells. ml and (41) cells. 100 ml consecutively. The study recommended exposing this type of water to solar radiation with special basins in order to kill bacteria and improve water quality.
