Sediment lead

[Jennifer Hubbard]

The latest issue of TIGHAR Tracks refers to sediment lead data in Gull Pond, stating Gull Pond's is 16 ppm vs. 12.7 ppm in most Newfoundland ponds.
I am very interested in this info (new to me though described in the article as an old question, so may pre-date my membership). I am a retired environmental scientist, and one of the things I did for more than 30 years was to look at thousands of soil and sediment results. My initial reaction to seeing these numbers is that they don't strike me as being that different, given the large variability I typically saw in sediment samples, and 16 ppm would typically not be considered a remarkable result. But really, to reach any solid conclusion when comparing data sets, I always wanted to have the full data sets and to know how many samples were collected, and to see the range and variance of each data set as well as the mean, and to use statistical tests to determine whether they were likely similar or not. I wondered, are the sediment data and the comparison pond data available anywhere on the TIGHAR site?

I think not.

It's not a question that I remember seeing asked and answered here.

That doesn't mean that Ric or other associates in the project do not have such data available to them.
