No criteria. No red line. No benchmark. Mostly nothing except perhaps history to show citizens, the public and TRAC members how much pumping is absolutely required to keep Uniroyal Chemical's contaminants from flowing off-site via groundwater. GHD and Lanxess mutter about circumstances and varying conditions. They suggest that it takes several geniuses plus a pinch of fairy dust in order to determine the amount of on-site pumping required in the Municipal Upper Aquifer to contain their site.
Bull**it says I ! All anybody has to do is assemble the on-site pumping data from the last three or four years and compare it to each month's off-site pumping. The two are related in that from the very beginning we were told that the vastly higher off-site pumping will challenge the on-site pumping by drawing down the off-site aquifer's elevations and tend to draw on-site groundwater off-site. It's all about the relationship between the two numbers.
In 2022 eight months exceeded 4.0 litres per second on-site pumping with the four months below 4.0 averaging 3.6 litres per second (l/sec).
The same year total off-site pumping exceeded 55 l/sec for eleven of the twelve months which is quite high historically
In 2023 four months met or exceeded 4.0 l/sec on-site pumping with the remaining eight months averaging 3.7 l/sec.
The same year total off-site pumping exceeded 55 l/sec for eight months and was between 24.6 and 55 l/sec for the rest.
In 2024 zero months exceeded 4.0 l/sec on-site pumping with twelve months averaging 3.4 l/sec.
The same year total off-site pumping exceeded 55 l/sec for five months with the remaining eight months averaging 37.4 l/sec.
To date in 2025 zero months met or exceeded 4.0 l/sec on-site pumping.
This year (Jan.-March) total off-site pumping has exceeded 55 l/sec. for two of the three months and the third month was at 41.1 l/sec.
The conclusions are obvious. Lanxess are reducing both on-site pumping dramatically the last four years at the same time that off-site pumping has also been reduced albeit less dramatically.
So are they intentionally wimping out on all pumping and treating to save on costs and or are they intentionally reducing on-site pumping more in order to drag contaminants off site that if treated will be treated partially at taxpayers' expense versus all their own expense?
