Notes

The sample was taken from the creek that feeds into Lake Ontario at Jones Beach. Before arriving at the spot, I observed two ducks and a seagull standing in the shallow and still water, and one of the ducks defecated in it. The numbers for the E.coli results are just the total number of dots on each card from 3ml samples on each, without multiplying or dividing anything as the instructions were conflicting.
