If we are relying on scientists to determine if the water is safe to drink and if the fish are safe to live , then it should be quite a comprehensive test ,the "poking with a stick 'is the preliminary test.It should be tested to see what exactly it is ,we are being led to believe that this is a naturally occurring bacteria that was there before.
The fact that they observe thats its not petrochemical,but it has these components of organic material does nothing to identifiy the offending compounds.
If you are inferring that the sheen,of which is minimal ,is not a result of the spill then you are the one spreading the misinformation .
As for people taking water samples,sure they are thorough taking the samples its just the control of information and results that I disagree with.Keep in mind that the government is in the mining business.
If you look at the data you see that the level of copper contamination is 10 times that of what it should be,especiallly at several depths which is in line with what would happen to this compound if its suspended in water .Of course none of it will float on the surface ,any 1st year science student knows that.To me these are the dangerous and deadly compounds that will contaminate the water for fish and people alike.
By doing the test they did in the field they were able to narrow it down to what they felt it was. It was either petroleum or plant/animal decomposition. It's floating on the surface and is not mixing with the water (not soluble in water). Based on their experience they then had the sample analyzed for the presence of tannins and lignins which are components to look for if it's decomposition of plants and trees. Following this field test, lab results confirmed the presence of tannins and lignins. If they really thought it was something mysterious they would have tested for it. Absolon said it best:
Attacking the testing because it isn't providing the answers one says it should does nothing to establish the testing is flawed or establish any credibility for a thesis..
You are expecting some extensive comprehensive test or else the results are flawed.....and perhaps those techniques are used
when applicable, but when they are not applicable it doesn't mean that the situation is not treated as seriously. Those are the decisions made by professionals that deal with water quality. You're not an expert in that field yet you have come to the conclusion that a comprehensive test is warranted. You are basically insinuating they do not know how to do their jobs but in actual fact you have no idea what the job entails.
Again, MOE is not closing the book on this. If more of this sheen can be found then more samples can be taken. This not limited to government staff as First Nations and UNBC have been provided kits to conduct this sampling. Morton, Suzuki, Staniford, or some homeless guy in Williams Lake (which can also be Staniford) can go take samples of this sheen and have it sampled at the lab of their choice. You can do this also. The evidence to date does not support that this sheen is from the spill. On the other hand, you are making unsubstantiated claims that this is the result of the spill, but have not provided any evidence that supports that opinion - none. That is misinformation.
You are now latching onto the copper concentrations from the water sampling results. While on that track, MOE has discussed the presence of copper in the samples:
It should be noted that the much lower concentrations of the dissolved form of copper as compared to the very high level of total copper concentrations indicates that the total levels are associated with particulates and may not be as bioavailable (i.e. available for uptake by aquatic life). Exceedances of acute guidelines such as copper indicate the potential for impact to aquatic life dependent upon the magnitude, duration and frequency of the exposure. - Deborah Epps, M.Sc., R.P.

The confusing thing is that in one sentence you say that this is in line with what would happen if it's suspended in water, but then in the next sentence you say that "of course none of it will float". The other thing you need to keep in mind is that copper is an element - not a compound.....as any 1st year science student would know.
