SPECIFICS REGARDING SEDIMENT RESULTS (NOT SOILS!) IN STROH DRAIN

The following Table is a chart comparing the highest of four Sediment concentrations found in the bottom of the Stroh Drain by GHD on behalf of Lanxess Canada in their "2020 Canagagigue Creek Sediment and Soil Investigation". This data was released back in July 2021. ...................................................................................................................................... ...........................................................................................................................

Total................51............................................................................................. .............................................................................................................. 51 total samples including Stroh Drain. Only four samples (Reach 4) exceed Stroh Drain concentration of 24.4 ppt. Therefore 46/50 or 92% of SEDIMENT samples are below highest Stroh Drain concentration in this 2020 report done by GHD on behalf of Lanxess Canada. The term "Reach" refers to specific stretches of the Canagagigue Creek with Reach 4 being the area of the creek running through the chemical plant and Reach 2 much further downstream between Northfield Dr. and Jigs Hollow Rd. areas.
