Elizabeth Carranza,
chairman of Save Sierra Madre Network Alliance (SSMNA), said
“small-scale gold mining operations are scattered in different
watersheds and river systems of Sierra Madre. Since no government body
has been monitoring these mining operations, miners are releasing toxic
mercury into the waters. Mining also causes heavy siltation and erosion
and increases hazards and disaster risk especially to riverside and
low-lying communities.”
A report released
recently by SSMNA in collaboration with Philippine Pollution Monitor
said artisanal and small-scale gold mining operations exist in major
head rivers of three critical watersheds of Luzon—Angat, Umiray and
Marikina Watershed.
