EWL Sciences Pty Ltd
Earth Water Life Sciences Pty Ltd (EWLS), a specialist environmental consulting business wholly owned by ERA, provides strategic environmental advice to ERA and external clients.
The focus of EWLS in 2008 was:

the provision of scientific and technical data in support of:
- an application for the modification of the existing pond water treatment plant
to facilitate both pond and process water treatment
- the construction of the new pond water treatment plant
- the construction of a trial rehabilitation landform
- applications to raise the tailings dam walls to provide increased storage for
both process water and tailings
- the reduction of the risk to operations due to water impacts
-
the detailed evaluation of environmental monitoring data for the 2007/08 wet season at both Ranger and Jabiluka to demonstrate to regulators that water management and stockpile management have been effective in protecting the surrounding environment;
-
securing an agreement on annual plans of rehabilitation and the values of rehabilitation trust funds for Ranger and Jabiluka;
-
a significant focus on furthering the relationship with the Mirarr Traditional Owners by means of engagement on land management programmes including cultural heritage surveys, weed management and caring for country through traditional burning;
-
further development and validation of the Ranger site water balance model as the prime means of optimising site water management; and
-
the characterisation of land application areas that have been used effectively for pond water disposal during dry seasons in order to devise relevant and appropriate rehabilitation concepts for approval by regulators.
