Email Question 1

Q1. In July 2015, at the invitation of Kieren, Julie Law

and I attended the obtaining of water samples from bores on the Buffer land. To date the report arising from that testing has not, I believe, been presented to the community. When can the community expect to receive that report? Over two years is an inordinately long time.

A1. The groundwater results are assessed holistically

every 3 years. The next assessment report will be completed in 2018 for all sampling completed in the period late 2014 to December 2017.

Email Question 2

Q2. In November 2016 a number of bores were

installed in the housing area east of the dump. When can the community expect the preliminary results from that testing? It is nearly 12 months. Ample time to have results.

A2. The results have been incorporated into a letter
report. The report is currently being reviewed and will

be made available in the next four weeks.
