As previously noted, separate regression equations were
estimated for each water quality variable. The coefficients for
total suspended solids and dissolved inorganic nitrogen were
of the expected negative sign and were significantly different
from zero (see Table 3). Recall that levels of TSS and DIN are
associated with non-point source pollution or run-off resulting
in part from development activities and associated
impervious surfaces. Therefore, as TSS and DIN accumulate
within the watershed, water clarity will be reduced.
