Scientists and
environmental groups today said that the presence of cyanide in the
waters affected by fish kills in Rapu-Rapu island, Albay noted by the
Bureau of Fisheries and Aquatic Resources (BFAR) could have come from
the mining operations of Australian-owned Lafayette Philippines Inc.
(LPI) in the island. LPI runs a 180-hectare open-pit copper and zinc
mine occupying almost 80 percent of Rapu-Rapu.
The BFAR found traces of cyanide after it gathered water samples in the
affected areas on October 30, after fish kills from October 27 to 28
were reported by Rapu-Rapu residents. While the BFAR's Bicol bureau was
quoted in media reports as claiming that the cyanide levels found were
"tolerable" and "had no effect on marine life", it also clarified that
the agency "could not clear" Lafayette of any involvement and would
need deeper underwater analysis and advanced tests before it could
determine the cause of the fish kills.
"The BFAR's water tests indicating the presence of cyanide in the fish
kill areas near the mine leave many questions unresolved. Where did the
cyanide come from? Could have the cyanide levels been higher than
"tolerable" if the tests were conducted earlier and not two to four
days after the reported fish kills? Has a thorough sampling of
Lafayette's waste disposal facilities been conducted?," asked Kalikasan
Peoples Network for the Environment (Kalikasan PNE) National
Coordinator Clemente Bautista Jr.
Kalikasan PNE's consultants from the academic and scientific community
also raised concerns on the reliability and thoroughness of the BFAR's
October 30 water tests.
Ric Saturay, a geologist and University of the Philippines National
Institute for Geological Sciences (UP NIGS) faculty member, pointed out
gray areas in the BFAR and DENR statements on the Rapu-Rapu fish kills.
"The BFAR's initial findings on the fish kill are unreliable. Cyanide
findings in the water are not always conclusive, since it has a high
potential to degrade quickly and thus has a very high chance for
negative findings. If the cyanide registered tolerable levels on the
October 30 sampling, it is possible that the levels could be higher on
earlier dates," Saturay said.
According to Kalikasan PNE's Bautista, Rapu-Rapu residents from Sagip
Isla Sagip Kapwa (SISK), the community organization in the island,
reported that fish kills were first observed in Barangays Pagcolbon and
Malobago, the villages nearest to the mine site, on October 27 to 28
after heavy rains started hitting the island on October 26. Antonio
Casitas, SISK Spokesperson, said that the fish kills eventually reached
Barangay Poblacion, 7 to 8 km from these 2 villages, on the 28th of
October.
"As signs of fish kills were reported from as early as October 26 and
lasted up to October 28, the time lapse between actual fish kills and
water sampling by the BFAR on October 30 might have reduced the
original cyanide levels in the water," Bautista said.
Saturay also called attention to the BFAR and DENR's failure to
identify possible sources of cyanide found in the water samples.
"What are the possible sources of cyanide? The BFAR and DENR did not
clarify whether cyanide should be found in the water at all. The
probability that cyanide naturally occurs in the area is almost nil, so
most likely the cyanide would have to come from outside sources,"
Saturay said.
"Lafayette should be investigated as a possible source of cyanide found
in the fish kill areas," Bautista said, "Remember that Lafayette was
found liable for cyanide contamination in 2005. The Pollution
Adjudication Board (PAB) ruled last year that Lafayette violated the
Clean Water Act when it discharged waste water with a high cyanide
content into creeks on Oct. 11 and 31 2005, which caused fish kills
when the toxic waste hit open seas. The PAB fined RRPI a total of P10.4
million because effluents from the mine site exceeded the acceptable
cyanide level," Bautista said.
Engr. Virgilio Perdigon, a professor at Aquinas University in Albay,
added that the probe should have included the mine's waste disposal
structures.
"What is relevant is the fact that poison is impounded in the site at
the mercy of heavy rains. Moreover, the normal management of cyanide
(as presented by Ms. Carmelita Borbe Pacis through a powerpoint
presentation dated March 22, 2006) consisted of detoxification at the
tailings pond, and flow of detoxified liquid to the settling ponds and
polishing ponds before the liquid is discharged to the sea.
Investigation of the incident should therefore include the
detoxification process and the settling and polishing ponds," Perdigon
said.
Saturay also noted that other indicators were not explored in the BFAR
and DENR tests.
"Cyanide is volatile so that it's not always a good parameter. Other
heavy metals should also be measured. A study of benthic (sea bottom
dwellers) organisms, which are relatively immobile, should also be
conducted to verify the effects of mine waste in the water. Prevailing
ocean currents and fish migration routes should also be considered," he
enumerated.
Bautista called for an independent, objective and comprehensive probe
into the causes of the October 26-28 fish kills.
"The DENR's premature clearance of Lafayette despite the unanswered
questions in the BFAR tests shows the government's lack of capability,
commitment, and initiative to effectively monitor and assess its pet
mining project," Bautista said |
