Drinking Water Contamination

In August 1996, Greenland Corporation authorized an independent laboratory to perform an analytical test to determine the effect of a spill of Greenplus Hydraulic Fluid ES into a drinking water source.

The accepted theory in environmental circles is that one gallon of petroleum will contaminate one million gallons of drinking water. It was decided that a mix of one to one thousand would be a reasonable test to determine the contamination capability with the Greenplus environmentally safe fluid.

The test results were established by introducing 1 ml. of Greenplus Hydraulic Fluid ES into 1000 ml. of distilled water and then to determine the compliance with Washington State drinking water standards. These standards are ranked with some of the most stringent in North America.

To properly do the test, an emulsifying agent had to be introduced into the lubricant. This resulted in non-compliance levels for turbidity, colour and total dissolved solids.

If one extrapolates the detected levels of Nitrate at .161 compared to the primary standard maximum contamination level of 10, Greenplus Hydraulic Fluid ES could virtually be introduced into a drinking water source at the rate of one to one hundred before making the water unacceptable.

This by no means implies that one should not be concerned or take steps toward removing this quantity of foreign substance from a drinking water supply. However, when one relates this to petroleum oils, a significant difference in the detriment to the environment is established.

What does the phrase "environmentally safe" mean. Specifically, as used by Greenland Corporation, the term refers to the toxicity of our products as measured by the 96 hour bio-assay test on fingerling trout. Biodegradability does not factor into this definition since this term refers only to the length of time it takes for the product to breakdown through natural decomposition in nature. The Greenplus advantage here is the rapidness with which the process occurs under laboratory conditions as compared to the time required for petroleum to undergo the same process. Some petroleum products describe themselves as "virtually non-tonix" and "inherently biodegradable" when describing their products. Greenland proudly states that our products are non-toxic and rapidly biodegradable.
