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.
