Happy Wednesday everyone!
I'm hitting a dead end trying to figure out the requirements for my facility for water testing. For context, we make nutritional supplements/products. Currently we do quarterly water testing of each hand sink used within the facility (total of 10), each washroom (4) and each production room that has water used for cleaning equipment (4), I also added the mop sink to the rotation that is used to mix the chemicals that are used to clean the rooms. We also do a monthly test of our "purified water" which is used as an ingredient in some of our products and fermentations. We do a full panel for micro including indicator organisms and pathogen detection on all of these samples.
Now moving to the issue at hand, which is the annual water testing. The person running the program before I came along has the annual water testing being done referencing the following:
-CFR Title 40 Chapter 1 Subpart D part 141 Appendix A to Subpart O-Regulated Contaminants
-CFR Title 21, Volume 2 Part 165 Subpart B
-EPA-National Primary Drinking Water Regulations Complete Table
I suspect (due to the vast amount of over-testing) that the previous EM Specialist was very by the book. If it said it had to be done, she did it. Now I am dealing with a $4000 annual water testing requirement that I am trying to wrap my head around. The following results (see below) are reported for a sample of "purified water" (i do find value in this as it is an ingredient) and also a composite of the "wash water" (Handsinks + washroom water). We also pull the annual report for the city water we use in the facility to keep on file. Could someone help me figure out why she decided to do this much testing, and where the CFR and EPA requirements are applicable, in what type of facilities? It feels like she had set up the program to have testing requirements similar to an actual water treatment facility (the annual water test result last year was 87 pages long). Thank you for all the help!
