Valacta provides a water analysis service for their clients. There are a multitude of reasons a producer might want to have their farm water analyzed.

Annual water analysis is compulsory as a part of the Canadian Quality Milk program (see form 15 in the program workbook). Given that clients your milk recording samples are already being shipped to the Valacta laboratory, why not make life easier by including a water sample with the shipment. Save time, it is precious.
