(Kaieteur News) – Water supplied by the Guyana Water Incorporated (GWI) in Regions Four, Seven, and 10 fails to meet safe drinking water standards, according to the Public Utilities Commission’s (PUC) 2025 Annual Report, raising serious public health concerns for thousands of consumers.

The report measured water quality against World Health Organization (WHO) guidelines for three key indicators: pH levels (acceptable range: 6.5–8.5), turbidity (below 5 NTU), and iron content (below 0.3 mg/L). Water in multiple communities across three regions failed on all three counts.

Region 10 recorded some of the most alarming readings. Plants at Amelia’s Ward, the Linden Power Company (LPC), McKenzie, West Watooka, and Wisroc all registered acidic pH levels between 3.7 and 5.4, far below the safe threshold and corrosive enough to pose direct health risks. Turbidity at LPC and McKenzie ranged between 7 and 14 NTU, suggesting filtration systems are not functioning effectively. Iron concentrations reached as high as 1.76 mg/L, nearly six times the WHO limit.
