Pollution Monitoring Data
Pollution Monitoring Data
New changes under section 66(6) of the Protection of the Environment Operations Act 1977 (POEO) make pollution monitoring data publicly available in a timely manner from the 1st July 2012. This aims to improve the public's access to information and performance of the licence conditions.
WaterNSW will publish monthly pollution monitoring data within 14 days of the results of obtaining the data.
WaterNSW has one Environment Protection Licence (EPL) issued by the NSW Environment Protection Agency (EPA).
