tracer tests
• Measure distances between extraction well and monitoring wells.
• Measure groundwater levels present in all on-site wells prior to the test.
• Set up the injection equipment
• Prepare the tracer solution
• Prepare the visual standards
• Note that care should be taken for minimising the exposing of fluorescence solution and visual standards to the sun light.
• Commission the injection while monitoring the tracer in surrounding monitoring wells.
• Actual injection volume of solution will be determined in the field by visual observation of fluorescein dye in dose response wells.
• Following the completion of injection, waste should be removed, if generated any, and the site should be clean and tidy

"Classical Colorimetric Analysis – by strict definition, the term is limited to the techniques for visual identification and comparison of colored solutions. By common usage among analytical chemists, it has become a generic term for all types of analysis involving colored solutions. Identification of a substance by the hue of its solution is termed qualitative analysis. Determination of its concentration in a solution by comparison of the intensity of its color to color intensity standards is termed quantitative analysis. When the human eye is used as the detector, quantitative colorimetric methods have relatively poor precision. Moreover, the precision varies with the color because of the varying response of the eye to different colors. Most visual color comparison methods utilize white light containing all wavelengths in the visible region. Filters or monochromaters are seldom used because colorimetric methods are advantageous principally for their simplicity, speed and low cost, and for their modest demands for skill and training of the operator. Color intensities of solutions are usually compared to a set of permanent color standards. "
