M1 Stanley Street

Active Physico-Chemical Stanley Street

Monitoring has historically been conducted from the pedestrian crossing on the downstream side of the Stanley Street (Edwards Bridge), Warrnambool.

In February 2022, this site was temporarily moved 100m upstream onto the left bank of the Merri River, with sampling occurring from the new floating pontoon while the new bridge was under construction.

Sampling has since returned to the Edwards Bridge in 2024 once the new bridge was completed; undertaken on the downstream (southern) side pedestrian access.

---

From February 2022, the Stanley Street site is accessed via the floating jetty, 100m upstream of the bridge, on the left bank of the Merri River.
