Background and
Goals
Data collected in the 1980s and early 1990s caused concern about
dissolved nickel concentrations in the Houston Ship Channel system.
Sampling associated with this TMDL project used improved techniques
that revealed that the threat was much less severe than was
originally indicated. Modeling analyses predicted that nickel
concentrations could exceed water-quality standards in limited
areas during conditions of low flow, but the probability of such an
event is small. The goal of this project is to assure that nickel
loadings remain below the target amount, and that the water-quality
standard will continue to be supported.
