Dear Editor,
Upon reading the July 5, 2026 edition of THE 592 GUARDIAN summarizing the Public Utilities Commission’s (PUC) 2025 findings on drinking water quality in Regions 4, 7 and 10, I was embarrassed and astounded by the Guyana Water Inc’s (GWI) statement reported in the July 3, 2026 Kaieteur News article that “Water quality issues flagged by PUC affect only taste, colour and appearance, not safety”.
True to the Govt’s code of conduct, GWI attempts to deceive the people, not only by leaving out the actual measurements that would make it impossible to back up their ludicrous claim, but also insultingly tells the people not to believe the coffee coloured water they see with their own eyes. This GWI statement is nothing but irresponsible, callous and dangerous to the people’s health.
This issue is close to home for yours truly, since I happen to be one of the 11 Engineers specially trained by the United Nations Development Program (UNDP) to establish and run the GWI (originally GUYWA) initiated in 1972; so, knows first-hand of the world class Water Authority handed over to the PPPC Govt in 1992, only to see it descend to this abys of incompetence and neglect of its sacred mandate to provide reliable, clean and safe water to the public. Instead, the people are heartlessly advised that it is no big deal for them to drink water that is perilous to their health, while certainly not the same water consumed by Govt officials and their families.
In a normal country, it would have been an oxymoron for a country to be dubbed “the land of many waters” with “water, water everywhere but not a drop to drink” (Poet Samuel Coleridge).
The data analyses and facts – Human beings can survive without oil, electricity, etc., but never without water! A safe water supply is guided by scientifically developed safe standards and undoubtedly the most essential substance for the sustenance of human life. Consequently, let’s address the three contaminants highlighted by the PUC that falls out of the range of safe standards. They are: pH, turbidity and iron.
pH – The pH scale ranges from 0 to 14 with lower pH values corresponding to higher acidity. However, it is most important to note that the pH scale is logarithmic and not linear, meaning each unit change represents a 10-fold change in acidity. For example, a pH of 4 is 10 times more acidic than a pH of 5, and 100 times more acidic than a pH of 6. This means that the 3.7 pH measured at Linden is 630 times more acidic than the World Health Organization (WHO) safe pH limit of 6.5.
Highly acidic water at 630 times the safe limit is corrosive and can dissolve toxic heavy metals such the copper and lead from the plumbing lines, which wind up in your drinking water. Ingesting these metals can cause serious health problems such as cancer, stroke, kidney disease, memory loss, high blood pressure, reduced bone density, etc. It is more toxic for children, as their growing bodies absorb these metals much quicker. Further, water with a high acidity has likely not gone through proper filtration and may still contain pollutants like pesticides and chemicals making the water unsafe to drink.
Turbidity – As clearly defined by the US Environmental Protection Agency (EPA) “Turbidity is a measure of the cloudiness of water, and the higher the levels the more particles (which carry the pollutants) are present. It is used to indicate water quality and filtration effectiveness (such as whether disease-causing organisms are present) and higher levels are associated with higher levels of disease-causing microorganisms such as viruses, parasites and some bacteria.”
Notwithstanding that one doesn’t need a measurement to verify the obvious that coffee coloured water at Grove means extremely high turbidity, the actual measurement of 29 times the US EPA and WHO limits plainly points out the grave health risk of consuming such water that may indicate presence of disease-causing microorganisms such as viruses, parasites and some bacteria. Substantively, owing to constant flooding, flood water with disease-causing microorganisms from latrines, septic tanks, manholes and pipes transporting raw city sewage, will most likely leak into the drinking water pipe network; thus, testing for the presence of these microorganisms must be conducted, especially during and after floods.
Iron – Though at a high level of 3.35 mg/l, or 11 times the WHO guideline, high iron content is not a major health concern, and high levels are expected from the upper of the two major aquifers supplying Georgetown and the East Coast of Demerara. However, high iron levels may create operational and cosmetic problems, staining plumbing fixtures, sinks, dishes, and laundry with a rust color; and can build up inside pipes, reducing water flow and clogging appliances like dishwashers and water heaters.
Considering the above, is the nation led to believe that like the Guyana EPA, the GWI has become devoid of technically qualified professionals to advise against such statements that put the public at serious health risk?
I hope this missive will implore the GWI to immediately do the right and responsible thing to apologetically retract their advice to consume such unsafe water, and to follow-up with urgent actions to satisfy its only mandate to provide the nation with mankind’s most precious substance and basic need for a safe water supply, especially in a nation with the highest GDP. In the meantime, I humbly wish to dissuade the public from following GWI’s inexplicably advice that the water is safe, despite its irrefutable scientific indications of being hazardous to human health.
Sincerely,
Dr. Vincent Adams
