Appendix 'C' is a technical specification document from the City of Ocala's Water Quality Laboratory detailing the maximum acceptance limits for contaminants in deionized water, based on Standard Methods 23rd Edition Table 9020: II. The document establishes strict quality control parameters for various water quality metrics, including conductivity (< 2 µmhos/cm at 25 ºC), total heavy metals (< 0.10 mg/L), individual heavy metals like cadmium, chromium, copper, lead, nickel, and zinc (< 0.05 mg/L), total organic carbon (< 1.0 mg/L), total chlorine residual (< 0.10 mg/L), and heterotrophic plate count (< 500 CFU/mL).

The appendix provides a comprehensive table of contaminant limits that will be used to assess the quality of the deionized water system, with a specific statistical use test requiring a Student's t-value ≤ 2.78. These precise specifications are critical for ensuring the water meets the stringent requirements for laboratory testing and regulatory certifications, aligning with the City of Ocala's procurement requirements for maintaining a high-purity water system at their Water Quality Laboratory.
