*Monitor Wells 1 & 2 will not be used for interim payments but will have SSTLs for final payment.
** The concentration over SSTLs is the figure used to calculate the 25, 50 and 75% reduction payment levels.
*** These monitor wells are at or below detection limits or calculated SSTLs. The levels of contamination for these wells are not included in the Plume Initial Concentration Total.
