Surface water samples were collected from 10-
20 cm depth in acid washed glass or plastic containers
with Teflon coated lids (Greenburg et al.
1985). Water samples were stored at 4~ for preservation
and transported to either COE or LDEQ
analytical laboratories where both filtered and unfiltered
samples were frozen until analysis. The
samples were analyzed for nitrite + nitrate (NO2
+ NO3), ammonium (NH4 - N), total Kjeldahl nitrogen
(TKN), Total Phosphorus (TP), total suspended
sediments (TSS), and salinity (Greenburg
et al. 1985). Samples analyzed for NO 2 + NO~ and
NH4 were filtered in the laboratory using 0.45 um
millipore filters and concentrations determined by
automated colorimetric c~tdmium reduction and
automated colorimetric phenate methods, respectively.
TKN and TP were analyzed using acid-digestion
methods described by Greenburg et al.
(1985). Samples analyzed for TSS were filtered in
the laboratory through pre.
