Veterinary Handbook Contents 6.3 Water Quality ProblemsThere is a risk of water becoming contaminated and unpalatable or even toxic. Contaminants include urine, faeces, rust, oils, fuel, chemicals, salt water and electrolytes if added excessively. Storage tanks may be corroded, filling ports inadequately sealed, and animals may urinate and defecate into troughs or contaminate water with feed or saliva. Miscalculations and overdosing may occur when adding electrolytes to header tanks or troughs.BackNext
