Some of my issues my have a small bit to do with it,
but nothing is as high as is being reported concerning pesticides.
First the Percentages below the merrit parkwat were 25% presence - not above action levels.
Second, when doing calculations, the query for all tests, included a numebr of repeat positive tests.
Why, because i made a mistake:
In gathering all the information that i could on wells, there were times that the presence of a pool was not recorded or a well depth was recorded as what an owner remembered, not what a well drillers report showed. Since the query was a "grouped" query, so that the highest level of pesticide found would show, individual properties were counted twice.
This increased the number of tests significantly.
So in this blog, i am trying to give the most accurate information that i can.
The current number of 30% above action level is being reported and yet even with all my mistakes, it never was that level.
24% presence level and above the action level was less.
so here is what i have, correcting previous mistakes:
|total wells tested||766|
|less early test||713 (not using current methods and with poor detection levels.)|
Summary of extra information collected
|House Built||Well depth||well distance||pool Onsite|
Sum of pesticides
|Chlordane||Dieldren||Heptachlor epoxide||Transnonchlor||alpha chlordane||gamma chlordane|
Percentages (Dieldren and chlordane only)
|dieldren and chlordane both present?||percent|
|both dieldren and chlordane >= AL||percent|
In the meantime i am doing one last study on nitrate levels in the wells found with pesticides and not found a significant correlation
To those reviewing this, know there are probably more mistakes that i have made and i will correct them when i find them
