DEEPER YET ANALYSIS OF TOXIC RESULTS IN CANAGAGIGUE CREEK

Yesterday's post gave the individual numbers of criteria exceedances for DDT, DDE, DDD, Dioxins/Furans in both Creekbank Soils and Creek bottom Sediments at five locations in Canagagigue Creek. It also gave the percentage exceedances of these five parameters combined for each location. Today we are going to further break down the numbers. We will see the percentages of criteria exceedances Per Toxic Chemical at each location.

For the moment I will leave it up to the reader and see if you can see the significance in some of these exceedances of criteria by specific chemicals at specific locations.
