With regard to the Atlas composting farm, location M2043 Calingiri -
(1) What is the volume of groundwater per annum that has been applied to the composting windrows?
(2) Are the composting material stockpiles situated above a groundwater area?
(3) If so, what steps have been taken to prevent contamination of the groundwater?
(4) What monitoring bores, if any, have been placed around the compost stockpiles to determine if groundwater contamination is occurring?
(5) If not, why not?
(6) For what contaminants is the compost tested and what is the rate of leaching of heavy metals and other impurities from the compost into the soil and groundwater?
(7) Does the level of glass contamination in the compost make it unsaleable?

(2) No. (3) Not Applicable. (4) No monitoring bores have been installed. (5) Site specific considerations indicate that any leachate produced from compost is not considered to pose a significant contamination threat that would require groundwater monitoring. (6) The licence requires testing for arsenic, cadmium, chromium (total) copper, lead, mercury, nickel, selenium, zinc, DDT/DDD/DDE, aldrin, dieldrin, chlordane, heptachlor, HCB, lindane, PHC and PCBs consistent with the Western Australian Guidelines for direct Land Application of Biosolids and Biosolids Products, February 2002. (7) Should the compost be made available for sale, the level of glass contamination would be a commercial factor to be managed by the Atlas Group.
