Most Frequently Asked Questions  

Parameter Purpose of Test Method
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
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

10232
Iron Taste, staining concerns. Can cause deposition in plumbing systems. May indicate corrosion. 8008

COD
Chemical Oxygen Demand
Used as a surrogate for BOD, and for effluent reporting when allowed by discharge permits. Provides a measure of organic "food" available to biological treatment steps and an estimate of the effect of plant effluent on the receiving water body. Can be correlated to BOD on a plant-by-plant basis, if influent characteristics are constant. 8000
10067
Ozone Control disinfection processes/in-package disinfection Ozone is often used in place of chlorine, to avoid taste issues, etc. 8311
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
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
Hardness, LR/ULR Assure that demineralizer systems are producing ultrapure feedwater, to avoid scaling in boiler systems 8030
8374
Nitrogen, Total Monitor nitrogen (nutrient) properties of plant effluent. Also used to monitor product qualities. 10071
10072
10208
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

Also Consider  

Parameter Purpose of Test Method
Sulfate
 
Monitor mineral content/flavor issues. Regulated in drinking water. 8051
10227
Alkalinity Control flavor/sensory/quality issues in bottled waters. May be used to adjust product water (e.g. in brewing). 8203
8221
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
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
Oxygen, Dissolved LR Control oxygen content of boiler waters/feedwaters. Part per billion levels required for high pressure units. 8316
Sulfite Control concentration of sulfite-based oxygen scavengers (generally low pressure boilers). Also used in food processing systems and dechlorination of effluents. 8071
8216
TKN
Total Kjeldahl Nitrogen
Total of organic and ammonia forms of nitrogen. Used to assess waste treatment processes/effluents. Also used in measuring product protein levels. 8075
