This workshop is designed to teach proper analytical techniques of corrosion control parameters in potable water. Parameters covered in this course include pH, conductivity, and hardness and alkalinity titrations. For each parameter, samples will be analyzed, and method verification will be discussed and practiced. These parameters will be used in the calculation of a Langelier's Index, from which the corrosion potential of a water can be determined. The course objectives will be met by presenting test theory, incorporating practical applications of analytical techniques with hands-on experience with testing systems. Students are required to analyze water samples of known and unknown values.

Basic thru Advanced

*Road to Water Testing - General overview of why, when, and how people test water, including information on sampling. * Video segments that explain the chemistry of corrosionm the effects of corrosion, and calculation of Langelier's Index as an indicator of corrosive potential, lab will include calculation of LI using simulated data. * Introduction to the theory of pH measurement, how a pH electrode works, how to properly measure, calibrate, and verify pH, proper maintenance of the pH meter and electrode. * Calibration of pH meter, accuracy verification, pH and temperature measurement. * Introduction to the theory of conductivity/TDS measurement, how the conductivity probe works, calibration and maintenance, measurement of samples, the lab will cover calibration, verification, and maintenance, and measurement of the samples. * Theory of titration techniques, comparison of titrametric methods, discussion of hardness and alkalinity titrations, the

Members of the target audience include water plant operators, lab analysts and managers, quality control supervisors, regulatory personnel, and environmental protection staff - anyone who needs to perform or utilize the data from basic laboratory corrosion control parameter analysis.
