Kipp’s PCE contamination under–and past–Lowell School?

Kipp’s PCE plume on its way to drinking water well and Lake Monona

At the May 28 Madison Water Utility Board meeting, staff reported the following (from the minutes):

Madison Kipp Corporation/UW #8 Sentinel Well:

“Groundwater at the Madison-Kipp Corporation (MKC) facility continues to be monitored for VOCs. A new monitoring well (MW-25) was recently installed at the intersection of Ludington Avenue and Center Avenue, approximately 600 feet northwest of Unit Well 8. Preliminary sampling indicates low levels (1.6 ug-3.3 ug/l) of tetrachloroethylene (PCE) exist at a depth of 100-130 feet below the surface here. It appears that the edge of the PCE plume has reached this location. Conformational sampling has been conducted at this location and the pending result will be used to verify the presence and concentration of this compound. The installation of the sentinel well, proposed to be installed adjacent to Elmside Circle Park, remains on hold.”

In other words, the Kipp contaminant plume is under [and past] Lowell School. The phrase “the edge of the PCE plume has reached this location” implies that PCE just got there, but it is very likely the plume reached past Lowell School years ago [hence various breakdown products of PCE present in Well 8, which is past the school in Olbrich Park at the shore of Lake Monona.

Kipp should also pay for additional monitoring wells to the south and in the direction of Olbrich Park to determine the extent of its PCE plume in that direction. Who knows how many other homes and businesses have PCE under them?
