Saint Vincent and the Grenadines

Environment and health

The most challenging issue on Saint Vincent is the turbidity of the water. Turbidity can range between 10 and 75NTUs but can exceed 100NTUs during and after heavy rainfall events. The CWSA has implemented a strict maintenance programme at the water intakes (MoHWE/PAHO, 2013).

There are three laboratories that conduct water quality testing locally. The laboratory at the CWSA carries out weekly sampling at the larger treatment plants and bi-weekly sampling of water from the sources, smaller treatment facilities and areas along the distribution network. Tests are conducted to investigate chemical and microbial parameters (MoHWE/PAHO, 2013). The CWSA adheres to the WHO Guidelines for drinking water quality (WHO, 2011).

The Public Health Department of the MoHWE conducts routine spot checks at various sites around the island, mainly public stand pipes, clinics and schools. Analysis is conducted for residual chlorine, turbidity and pH.

The Saint Vincent and the Grenadines Bureau of Standards conducts water quality testing mainly on the bottled water for commercial use and export. Routine testing on the public water distribution system is not done unless it is requested by the Public Health Department in the event of abnormal results in their routine spot check.

In 2012, there were 880 people in the country affected by water-related diseases which include water-borne, water-based and water-based insect vector diseases. The majority of these reported cases were seen in the gastro intestinal infections (MoHWE, 2013).
