The
seven parameters which differentiated Bloody Pond, Little Long Pond and Long
Pond from the other three were Specific Conductance (indicating the presence of
salts), Sodium, Chloride, Calcium, Magnesium, Hardness (indicating primarily the
presence of calcium and magnesium) and Alkalinity(indicating
the presence of calcium as calcium carbonate among other things).
The box plots below show the range
of values for half of the water samples from each pond in red. The line across
each box indicates the middle, or median, value of the readings for each pond.
Whisker lines extend from the box to the highest and lowest readings with the
exception of instances where extreme readings are shown outside of this range.
