Risk Reactor's IFWB-C8 Yellow Green products are specially formulated versions of water tracing dye, certified by NSF International to ANSI/NSF Standard 60 for use in drinking water. This dye is the traditional fluorescent water tracing and leak detection material and has been used for labeling studies from the beginning of the century.

Risk Reactor Product Code and Name:
IFWB-C8 Fluorescent Yellow Green Water Tracer Additive Concentrate EPA Approved and NSF Certified for Drinking Water.

Product Description:
It may be detected visually, by UV light and by appropriate fluoremetric equipment. Today, it is most often used visually. This dye has been used by the military to mark downed pilots for search and rescue operations over large water bodies. Visually the dye appears yellow/green, depending on its concentration and under UV light as lime green. Based on biochemical oxygen demand (BOD) studies, the dye is biodegradable with 65% of the available oxygen consumed in 7 days. The dye is resistant to absorption on most suspended matter in fresh and salt water. However, compared to Risk Reactor's IFWB-C7 Red products it is significantly less resistant to degradation by sunlight and when used in fluoremetry, stands out much less clearly against background fluorescence. As always the suitability of these products for any specific application should be evaluated by a qualified hydrologist or other industry professional.

Certified To Meet EPA Standards This is a certification that these products conform to the ANSI/NSF Standard 60 for potable water as set forth by the EPA in The Clean Water Act.

Note: Our yellow green is recommended for shallow water bearing heavy sediment loads. Sandy soil will not absorb our Red or yellow green. Color is visible in clear water at one part per million.

How to Use:
How Fluorescent Dye Tracing Products Work: The "visual" aspect of our dye products refers to normal reflection of light as color. The "fluorescent" aspect refers to special properties of some chemicals to absorb certain wavelengths and then emit, rather than reflect, light in response. The emission can be seen by using a "black" ultraviolet light or precisely measure Yellow Green with a fluorometer. The reflected and emitted light have different wavelengths and are, therefore, not the same color.

Fluorescent Properties are of Greatest Value When :

- Tracing must be done when there is no sun or sufficient artificial light (in a sewer or a cave, for instance)

- Precise quantified data is required

- Very small amounts of tracing material is allowed.

The maximum Absorbance/Emission Wavelengths of Our Products are:

Product Color: Yellow Green

Absorption Emission: 490 nm 520 nm  

What Does PPB Mean? Most of our products contain fluorescent dyes, which can be detected visually, or with the use of ultraviolet light or fluorometer. As used in Risk Reactor literature, "ppb" refers to one part of active dye per billion parts of water. Using a fluorometer, the active dye can often be detected at levels less than one ppb. All data is presented as reference points only and should not be regarded as a recommendation. Users should make their own determination of appropriate dilution levels in any specific situation, which will vary with the nature, condition, and use of the water or liquid and the specific evaluation to be performed.

How to Calculate the Size of a Body of Water? One gallon of water occupies 1337 cubic feet. For a rectangular tank, multiply depth in feet times width times length divided by the factor 1337 to establish the number of gallons. For more complicated bodies of water, formulas can be found in scientific texts on water utility management, hydrology, etc.

For Stream Tracing and Pollution Detection: Introduce tracers into the water at the source or suspected source of pollution. Allow sufficient time as calculated, to permit the dye tracer to reach the effluent or recipient location. Take samples of water for analysis.

Light Stability: Yellow Green is recommended for yellow and green backgrounds such as algae rich water. Yellow Green, blue, and yellow green should be used in water bearing heavy sediment loads or when passing through soil with high clay content. Industrial Yellow Green will absorb onto either. Photo degradation takes place in sunlight at different rates for different dyes. Yellow Green takes from approximately five to seven days and yellow green fades in two to three days. Blue, on the other hand, breaks down in three to four weeks. The color of all dyes will disappear if the solution is mixed with chlorine. Add approximately 4 grams of 12% bleach to every gram of product in solution.

Examples of Specific Projects: Test sewer lines for infiltration. Locates sewer lines. Check for illegal connections. Prove septic bypasses. Identify indirect cross-connections. Check drain pipes, downspouts, and gutters to assure drainage into proper channels. Use in inspection service for certification and reinspection documentation. Analyze travel times. Toilet leak detection kits are frequently used by plumbers, municipalities and utilities use them as part of public relations and water conservation programs. Detect leaks in closed systems and cooling systems of steel manufacturers. Study infiltration and industrial water piping systems. Trace acid coming though cooling systems. Check pump systems flow in fleet trucks, and for preventative maintenance programs. Detect sewer leaks into ponds, lagoons, and reservoir lines. Check circulation through sludge beds and to measure discharge flow from water tanks. Illustrate the hydraulic characteristics of streams and other water bodies. Identify and differentiate batches of slurry before the brick firing process. Measure the speed and longevity of material passing through a system (i.e. retention time studies).
