Most Frequently Asked Questions
| Parameter | Purpose of Test | Method |
|---|---|---|
| Ozone | Control disinfection processes/in-package disinfection Ozone is often used in place of chlorine, to avoid taste issues, etc. | 8311 |
| Flouride | Control disinfection processes/in-package disinfection. Ozone is often used in place of chlorine, to avoid taste issues, etc. | 8029 |
| Chlorine, Total |
Data used to control Chlorine based disinfection processes, required for reporting at POE and in the distribution system, also used in monitoring in the distribution system during flushing and line break maintenance. EPA Primary DW Standard at 4.0 mg/L as CL2. | 8167 10070 10232 |
| Alkalinity | Control flavor/sensory/quality issues in bottled waters. May be used to adjust product water (e.g. in brewing). | 8203 8221 |
| Hardness, Titration | Monitor incoming water for mineral content. Adjust product water quality and sensory factors. Monitor performance of water softening systems, to avoid scaling and assess load on reverse osmosis systems. | 8213 8226 |
| Calcium (Ca Hardness) Titration |
Monitor incoming water for mineral content. Adjust product water quality and sensory factors. Monitor performance of water softening systems, to avoid scaling and assess load on reverse osmosis systems. | 8204 8222 |
| Chlorine, Free |
Data used to control Chlorine based disinfection processes, required for reporting at POE and in the distribution system, also used in monitoring in the distribution system during flushing and line break maintenance. EPA Primary DW Standard at 4.0 mg/L as CL2. | 8021 10231 |
| Turbidity | Monitor particulates, membrane purification system loading and failure. Turbidity is often used as a surrogate for some microbial monitoring. | Turbidimeter (2100xx) - see instrument manual |
Also Consider
| Parameter | Purpose of Test | Method |
|---|---|---|
| BOD Biochemical Oxygen Demand |
Form as unwanted disinfection by-products when organic matter reacts with chlorine (or bromine). Current EPA regulations allow no more than 80 ppb of total THMs in drinking water supplies. | 10224 |
| Chloride | Monitor incoming water/control salt content for taste consistency/health issues. | 8206 8207 8225 |
| Conductivity | Monitor mineral content of incoming water/taste/salt content/wastewater processing. Also used to control boiler blowdown and cooling system dissolved solids concentrations. | 8160 Conductivity meter and probe |
| Iron, Ferrover | Monitor mineral content and flavor issues. | 8008 10229 |
| Manganese, LR | Monitor mineral content and flavor issues. | 8149 |
| Nitrite, LR | Regulated in drinking water, with nitrate. | 8507 10019 10207 |
| pH (buffer) | Standardize pH meters for control of pH throughout plant. Monitor acid content, flavor stability and/or contamination. | pH meter & electrode - see instrument manual |
| Phosphate, Total | Can be used as a corrosion inhibitor in cooling systems and drinking water distribution systems. Also used as a boiler treatment, to precipitate calcium and avoid calcium sulfate scale formation on surfaces. Total phosphate includes reactive (ortho), inorganic (poly) and organic forms. | 8190 10209 10210 |
| Potassium | Monitor mineral content and flavor issues | 8049 |
| Sulfate |
Monitor mineral content/flavor issues. Regulated in drinking water. | 8051 10227 |
