Water analysis
Knowing the quality of the water used on the farms is essential to avoid both contamination in the process of washing the milking facilities and milk storage tanks as well as health problems in the cattle.
In the LIGAL physicochemical and microbiological parameters are determined to confirm the suitability of the water supplied to the livestock, and employed for the cleaning of the facilities which are in contact with milk.
