Several hectares of coastal wetlands which feed into the Bellinger River at Urunga had been declared a complete dead zone and was unable to be restored.
DANGEROUSLY high levels of arsenic and antimony in Mine Creek, which feeds into Wild Cattle Creek, has ignited debate about antimony mining in an area which leads into the water supply of the Clarence and Coffs Harbour regions.
Wild Cattle Creek is one of the major tributaries of the Nymboida River which leads into the Clarence and also supplies water to Shannon Creek Dam.
A map commissioned by Anchor Resources, the company which is licenced to explore, but not mine the site at Beilsdown, shows Mine Creek at one point had 377 ug/litre (parts per billion) of antimony which is 126 times the Australian and New Zealand Environment Conservation Council's (ANZECC) guidelines for drinking water.
