Why should I be concerned?

Dairy wash water is usually considered a dairy sanitation problem. If not carefully managed, however, dairy wash water can contaminate both surface and ground-water sources.

The amount of wash water generated varies with milking preparation, equipment used, and the number of cows. A 100-cow, free-stall operation may use anywhere from 100 to 1,000 gallons of water per day in the milking center alone.

Milking center wash water is contaminated with organic matter, nutrients, chemicals, and microorganisms. Poorly designed or mismanaged waste water disposal systems can contaminate surface and ground water with ammonia, nitrate, phosphorus, detergents, and disease-causing organisms. Surface water can also be contaminated by manure, milk solids, ammonia, phosphorus, and detergents.
