Notes:

-
For DO, non-compliance of the
water quality limits occurs when monitoring result is lower than the limits.

-    For SS, non-compliance of
the water quality limits occurs when monitoring result is higher than the
limits.

-
All the figures given in the
table are for reference only and these may be amended with the agreement of
DEP.

-
“Depth Averaged” is
calculated by taking the arithmetic mean of the in-situ parameters readings
at all three depths.  For
suspended solids “depth averaged” is calculated by combining all three
samples into one mixed sample which is analysed to produce a physical
arithmetic mean.
