NPHIL Laboratory Analysis Confirms Compliance with WHO and National Standards
MONROVIA – The National Public Health Institute of Liberia (NPHIL) has officially cleared Diamond Mineral Water of contamination allegations, confirming that the product is safe and fully compliant with national and international drinking water standards.
The confirmation follows days of speculation on social media, where posts accused the company of distributing “contaminated” or “dead” water. In response, NPHIL’s Central Environmental Health Laboratory conducted a full-scale water quality analysis between October 18 and 21, 2025.
Released on October 22 under Report No. CEHL-WQAR-25-256, the laboratory findings show that the 330ml bottled water sample from National Beverages Inc., producers of Diamond Mineral Water, meets every safety parameter outlined by both Liberia’s regulatory framework and the World Health Organization (WHO).
According to the report, the sample recorded no presence of Total Coliform or E. coli, the bacteria most commonly associated with waterborne contamination. Physical indicators such as pH (7.5), color (0.0 CU), turbidity (0.0 NTU), conductivity (80 µS/cm), and total dissolved solids (40 ppm) all remained within acceptable limits. Chemical tests also confirmed that ammonia, chlorine, iron, and sulphate levels were well below the recommended thresholds.
The analysis, conducted by Massa S. Kandakai and validated by Francis D. Jaryan Sr., Water Quality Coordinator, officially certified Diamond Mineral Water as safe for human consumption.
At a press briefing on October 21, Hawa Ndama, Human Resource Manager at National Beverages Inc., denounced what she described as an orchestrated campaign of extortion and defamation against the company.
“These social media reports are completely false,” Ndama said. “Some individuals pose as journalists or bloggers, fabricate damaging claims, and demand money to suppress the stories. When we refuse, they post misleading content to tarnish our image.”
She clarified that one of the videos circulating online purportedly showing unsafe bottled water was traced back to 2023 and bore no connection to Diamond Mineral Water’s production plant.
“The owner, Mr. Atagari, and our staff drink this same water daily,” she emphasized. “We would never compromise the safety of our customers or ourselves.”
Ndama further stated that the company will collaborate with the Liberia National Police to investigate what she called “cyber harassment and blackmail targeting law-abiding businesses.”
With the NPHIL report now public, National Beverages Inc. says it feels vindicated. The company reaffirmed its commitment to quality assurance, emphasizing that every batch of bottled water is tested before distribution.
“We maintain strict hygiene and production standards,” Ndama said. “Our certificates and testing records are always available for inspection.”
The national health authority also urged Liberians to rely on verified information from accredited laboratories and government agencies rather than unverified social media content when it comes to product safety.
As misinformation continues to circulate online, the NPHIL clearance serves as both reassurance to consumers and a reminder of the importance of evidence-based public communication.
