Water, our life-sustaining resource, is crucial for our well-being and the environment. Its quality, determined by chemical, physical, and biological factors, impacts everything from drinking to agriculture. Ever wondered about the tiny living things in water? These waterborne micro-organisms, like bacteria and algae, are more than just microscopic inhabitants; some can pose serious risks to human health.

Microbial Menace: In various water sources, there’s a diverse community of waterborne micro-organisms. Some are friendly, while others, known as waterborne pathogens, can cause diseases like typhoid fever and cholera. In places with limited access to clean water, these tiny troublemakers contribute to over 100,000 deaths among children under five in Nigeria alone.

Microbial Contamination

When harmful substances make water unfit for its intended use, we face microbial contamination. Bacteria like Escherichia coli (E. coli) signal fecal contamination, while viruses such as Hepatitis A can be transmitted through drinking water. Algal blooms, caused by rapid algae growth, not only make water smell bad but also produce toxins leading to health issues.

Effects of Harmful Microbes

Harmful microbes don’t just threaten our health; they disrupt aquatic ecosystems, causing fish deaths and damaging the food chain. Waterborne diseases like diarrhea and cholera hit vulnerable populations hard. Contaminated water used in food production can lead to outbreaks, damaging public health and economies.

Importance of Water Quality

Testing water quality is crucial for human health, environmental well-being, and economic sustainability. It helps prevent waterborne diseases, protects aquatic ecosystems, sustains economies, and supports plant and animal health in agriculture.

Water Purification

Purifying water involves removing or reducing contaminants to make it safe for use. Techniques include filtration, disinfection (using methods like boiling or chlorination), ultra-filtration, and chemical treatment. Each method tackles specific types of contaminants.

Water Quality Management

Maintaining water quality requires regular monitoring, proper sewage management, sustainable sanitation practices, and public awareness. Monitoring helps identify threats, while good sewage management prevents diseases. Hygienic practices, including handwashing and proper waste disposal, contribute to water quality. Public awareness campaigns play a key role in promoting clean water practices.


Microbes in water can impact our health, environment, and development. Understanding the risks, implementing effective monitoring and treatment, and promoting sustainable water management practices are essential for ensuring access to clean and safe drinking water. Prioritizing efforts like water quality testing, compliance monitoring, and embracing water treatment technologies is crucial for providing quality water for all.

As the current COP28 conference gains momentum, the focus on reducing methane emissions in the oil and gas sector remains a key element in combating global warming. Recognizing the potency and short-lived nature of methane, fifty prominent oil and gas companies have reiterated their commitment to reaching near-zero methane emissions by 2030. Additionally, a fund has been established to support methane abatement projects in emerging markets and developing economies.

Nigeria, as a major player in the oil and gas industry, understands the significance of addressing methane emissions. President Bola Tinubu has expressed his government’s commitment to ending gas-flaring in the country, aligning with the global push to halt methane emissions. In line with existing methane guidelines, Nigeria has signed off on reduction programs and plans to leverage new technology to achieve its methane pledge.

The Nigerian National Petroleum Corporation (NNPC) has taken proactive steps to prioritize this issue and contribute to the global reduction effort. Their commitment demonstrates Nigeria’s dedication to reducing methane emissions and achieving zero flare in its operations by 2030. The NNPC has supported the oil and gas decarbonization charter (OGDC) released at the ongoing United Nations Climate Change Conference (COP28) in Dubai, United Arab Emirates (UAE). The charter urges the oil and gas sector among other things to achieve net-zero emissions for their operations by 2050. During a panel session titled ‘Accelerating the elimination of methane emissions & the decarbonization of oil & gas,’ Oritsemeyiwa Eyesan, executive vice-president (EVP) of NNPC Limited, emphasized the charter’s importance for a major African national oil company.

The global energy sector was responsible for approximately 135 million tonnes of methane emissions in 2022, slightly higher than the amount in 2021. Both oil and natural gas operations accounted for around 40 Mt of emissions, with an additional nearly 5 Mt from leaks in end-use equipment. Implementing well-known measures like leak detection and repair (LDAR) programs and upgrading leaky equipment can reduce emissions in the oil and gas sector by over 75%. In Africa, Osten has been at the forefront of LDAR programs, utilizing Optical Gas Imaging (OGI) technology to effectively address methane emissions in the energy industry.

As Nigeria continues to navigate the transition toward a low-carbon future, its commitment to methane emission reduction sets a positive example for other countries and industry players to follow. By working collectively and implementing effective strategies, we can make substantial progress in combating global warming and achieving a sustainable future.
