(Trinidad Guardian) Lead concentration at the Guanapo Landfill was up to 75 times more than the acceptable level when samples collected by the Department of Chemistry at the University of the West Indies, St Augustine campus were tabulated, according to a May 2016 report done by the UWI scientists.
The 71-page report entitled: The Impact of the Contaminants Produced by the Guanapo landfill on the Surrounding Environment was made available to Guardian Media yesterday, following assurances on Thursday by the Water and Sewerage Authority (WASA) advising the public that the water supply from the Caroni and other water treatment plants meet World Health Organisation (WHO) standards for drinking water quality and was therefore safe to drink.
On Page 67, the report stated, “There is a concern as the levels are greater than acceptable levels for drinking. That water in the river is currently being used as potable water supply.”
The report stated that controlling mechanism appears to be dilution of contaminants levels in the base flow, which is derived from the ground water aquifer near to the Guanapo landfill, which is about four kilometres south-east of Arima.
