The long term Environmental Monitoring Program of PT. Freeport Indonesia is designed to monitor potential impacts by routinely measuring the water quality, biological, hydrological, sediment and meteorological characteristics throughout our operation area.
Normally every year more than 7,000 samples, which produce more than 50,000 separated analysis results, are used to develop scientific information that are needed to make management decisions related to our operations, so that we are able to minimize and mitigate the environmental impacts.
PT. Freeport Indonesia owns an environmental laboratory in its area, which produces data analysis to be used in the monitoring program. This laboratory has obtained the ISO 17025 quality standard certification for analytical laboratory from the Indonesian National Accreditation Committee. As part of the environmental audit carried out by the Government of Indonesia, Sarpedal (Government Environmental Laboratory) collects the samples of water, sediment, fish, surface water, and funnel emission. The results routinely confirm the data of PT. Freeport Indonesia.

In 2002 PT. Freeport Indonesia submitted the Ecological Risk Assessment report to the Government of Indonesia at a detailed Ecological Risk Assessment on the sirsat management system, which evaluates the potential tracks that may affect the health of flora, fauna and human beings. This detailed assessment strengthened the basis for approval of the sirsat management system in AMDAL.
We have assigned a review on the important conclusions of this study in 2007, which is still in process. A sirsat impact study was conducted in 2002 on the local public health as well as on the biodiversity. The methodological validity of this study from various aspects was then reviewed and the conclusions were made by an independent panel team consisting of reliable experts. The result of the study shows that the damage on the ecosystem and human health was not proven. Nevertheless, the result of this study also required us to take the follow up steps. The control on the new existing condition should be made since it is not possible for the sirsat area to fully return to the initial condition
Our biology program monitors more than 200 sampling locations for nekton, benthos, and plankton. Results of the current monitoring show that the samples of fish and shrimp meat from the sirsat area are worthy for consumption, as regulated in the quality standard of Indonesian food.
The data from biological samples continuously show that the estuary at the upstream of the sirsat sedimentation area is the ecosystem that functions based on the total species and total specimens that are collected, either from nekton as well as from swimming organisms, such as fishes and shrimps.
