NSW Department of Health Fact Sheet on Mercury
On 30 April 2012 Orica submitted a Groundwater Monitoring Plan to the NSW EPA for annual monitoring for mercury in groundwater. Groundwater sampling under the Plan was carried out between December 2012 and December 2016. Ongoing groundwater monitoring in the vicinity of the FCAP is continuing in accordance with the Ongoing Maintenance Order. Reports are available on request.
Site Audit Statements
The FCAP Project was overseen by a NSW EPA-accredited Site Auditor, Mr Chris Jewell. He prepared the following Site Audits:

Human Health and Environmental Risk Assessment Report (HHERA) 2013
In 2008 a Human Health and Environmental Risk Assessment (HHERA) was prepared to assess the potential risks to human health and the environment associated with mercury in soil and groundwater.
In late 2012 the NSW EPA requested a review of the 2008 HHERA in order to consider more recent monitoring and toxicity data and a revision to the National Environment Protection Measure (NEPM) for Assessment of Contaminated Sites.
The Revised HHERA was reviewed by the NSW EPA and is provided below.
