2.1.2 Annual Metals Testing
Annually, water obtained from the Aries Vaponics units in Rooms 002 and Room 019 will be
tested for lead, cadmium, chromium, copper, nickel and zinc. These contaminations will be at a
level of less than 0.05 mg/L per contaminant and less than 0.1 mg/L when added together.
Corrective Action
If the annual metals testing reveals metal value(s) at a level greater than acceptable then the
water will not be used for microbiological purposes until another sample is taken and returns an
acceptable value.
2.1.3 Monthly heterotrophic plate count
Monthly a sample of water from Room 002 and 019 will be analyzed for heterotrophic plate
count. The test results will be less than 500 CFU/ml.
Corrective Action
If the monthly heterotrophic plate count(s) return a value greater than 500 CFU/ml then the
affected water source(s) will not be used for microbiological purposes until another sample is
taken and returns an acceptable value.
