Papua New Guinea faces challenges in providing clean water and sanitation. A national policy and specific school standards have been developed to address this. The goal is to improve student health and education. All schools are expected to implement this policy, which will be used by all relevant stakeholders. Successful implementation is expected to positively impact the health of the country's youth.

A study in Nigeria's Niger Delta found that oil spillage negatively impacts groundwater quality. Water samples from areas with a history of spillage showed higher levels of hydrocarbons and turbidity, and were more acidic than samples from uncontaminated areas. This suggests the need for water treatment and comprehensive groundwater monitoring in the region.

Microbial pollution in water bodies poses a significant health risk. Current monitoring methods, like turbidity measurements, have limitations. This review examines the origins and behavior of waterborne microorganisms, existing optical detection methods, and proposes new research avenues, particularly in light of increased heavy rainfall due to climate change.

This study investigated the effectiveness of various porous materials (birch bark, cork, glass wool, and polyurethane foam) in removing petroleum substances from water. Both static and dynamic methods were employed, using model water with different concentrations of petrol and diesel fuel. Results indicated that birch bark and glass wool consistently outperformed cork and polyurethane foam in reducing mineral oil index and n-alkane concentrations. The removal efficiency for n-alkanes was notably higher than that of the mineral oil index across all materials and methods tested.

This resource aids in selecting suitable water containers for various purposes. It details ideal container features, biofilm prevention, and compares common emergency water containers with their pros, cons, and cleaning methods.

Pitahaya, guasimo, and nopal plant extracts effectively remove turbidity, color, chlorides, and nitrites from surface water. The combination of pitahaya and guasimo extracts even removed 100% of nitrites. These plants show potential for treating water for human consumption and industrial use.

This paper presents a low-cost system for real-time water quality monitoring using in-pipe sensors. It combines electrochemical and optical sensors to detect contaminants like E. coli and arsenic at low concentrations. The system is designed for large-scale deployment and provides valuable data to consumers, companies, and authorities, serving as an early warning system for contamination.

This review article compares various sustainable adsorbents for removing pollutants from water. It covers natural, carbon, waste, biomass, biopolymer, nanocomposite-based adsorbents, as well as metallic organic frameworks and other novel materials. The review discusses characterization, modification, adsorption capacities, isotherm models, kinetics, and the impact of factors like pH, temperature, and particle size. It also addresses adsorbent formulation, optimization, cost-effectiveness, thermodynamic parameters, regeneration, reusability, molecular modeling, and future perspectives.
