Hello All!
I am currently working on revising our water and air quality testing programs. For water we do not use it in our processing at all, not as an ingredient or processing aide, nothing! We currently only use water for cleaning. Prior to this year our company was testing water extensively, like 10 page report extensively. I came on board a recommended a reduced testing profile of heavy metals, Heterotrophic Plate Count, E.coli and Coliforms. I found recommended levels for HPC, E.Coli, and Coliforms but am struggling to find acceptable levels for heavy metal testing.
Does anyone have experience with heavy metal testing in water and acceptable limits for Arsenic, Cadmium, Lead and Mercury? I am having no problem finding drinking water standards but our products are used in pet and livestock. Our finished products are also testing for heavy metals to ensure our product meets customer standards.
Any advice is appreciated!
