Downstream sites had higher metal concentrations.
Threshold levels of Ni were exceeded by STW, NYL and MDD.
SQGs were surpassed for Zn at GC and NYL.
NYL and MDD were determined to be of concern by multiple indices as well as multivariate statistical analysis.
The pH had a clear effect on metals in sediment.
