Description
Excerpt: Trend monitoring involves long-term monitoring of changes in one or more parameters. As discussed in this guidance, public attitudes, land use, and the use of various urban BMPs are examples of parameters that could be measured with trend monitoring. Isolating the impacts of MMs and BMPs on water quality requires trend monitoring.
