This benchmark measures how many health advisories exist on state lakes, streams, bayous and Gulf shores, and how many areas are affected. Advisories for (typically) mercury, chemical and fecal coliform contamination gain sharp public attention and, it is hoped, will mobilize remediation actions.

It should be noted that increased monitoring efforts for mercury contamination in fish may further increase the advisory total before any reductions are realized.

Clean surface water bodies are essential for recreation, fishing and tourism.

Trend is inconsistent. Mild aggressive-positive method used.
