 Abstract

The second wave of the COVID-19 pandemic in India brought unprecedented challenges to the public health system. Ensuring access to safe drinking water became critically important during the pandemic due to increased health risks. The rural population was particularly vulnerable to infection due to the consumption of contaminated water sources. The aim of this study is to evaluate the efficacy of household water filtration systems used during this period. Water quality testing and household surveys were conducted across three rural districts in Bihar, Uttar Pradesh (UP), and Madhya Pradesh (MP). A total of 500 households were randomly selected to represent users of different filtration technologies. Water samples were analyzed for key parameters including total coliforms, Escherichia coli, turbidity, pH, and residual chlorine, in accordance with the Bureau of Indian Standards (BIS). This mixed-method approach enabled both statistical and contextual interpretation of household filtration performance. The highest E. coli removal was observed in boiling and reverse osmosis (RO) systems. UV-based purifiers demonstrated variable performance, with efficacy ranging from 85% to 92%. Ceramic and cloth filters showed moderate to low performance. The study found a clear correlation between the use of highly effective filtration systems and lower reported cases of gastrointestinal illness. These results suggest that proper household water treatment practices can significantly reduce health risks during public health emergencies. This research emphasizes the importance of household-level water treatment during crises and highlights the need for targeted policy interventions to promote affordable and effective water purification technologies in rural India. The findings offer valuable insights for disaster preparedness planning. Future resilience models must incorporate water safety, public health priorities, and social equity considerations.

 Abstract

The necessity for comprehensive and scalable security solutions has increased as software development increasingly uses CI/CD pipelines. Traditional security practises sometimes fall behind rapid development cycles, leaving weaknesses for unscrupulous actors to exploit. Adding AI-based security mechanisms to CI/CD pipelines can enable proactive threat detection, automated vulnerability assessments, and continuous monitoring without slowing down development. This study discusses AI-based security in CI/CD pipelines and its advantages. This article examines the constraints of typical security techniques in CI/CD settings, where quick deployment frequently clashes with extensive security testing. AI-based security technologies use machine learning algorithms to evaluate massive volumes of data, detect risks in real time, and react to new attack vectors faster than previous techniques. Automation of security testing across the development lifecycle is a major benefit of AI-based security in CI/CD pipelines. By combining AI-driven static and dynamic code analysis, anomaly detection, and automated penetration testing, enterprises can make security a priority throughout development. Traditional security systems have high false positive rates, but these technologies can learn from fresh data and improve accuracy. By detecting and responding to threats in real time, AI-based security helps improve CI/CD pipeline responsiveness. These solutions utilize AI models based on historical data to detect vulnerabilities and automatically roll back deployments or apply security updates. This preemptive technique limits attackers' window of opportunity and the danger of delivering tainted code into production. AI-based security in CI/CD pipelines ensures continuous monitoring and audit trails, supporting industry norms and laws. AI-driven solutions can log security actions, provide compliance reports, and notify teams of policy violations. This is useful in highly regulated businesses where security criteria must be met. However, CI/CD pipelines with AI-based security face issues. AI model complexity, training dataset size, and adversarial assaults on AI systems must be handled. Integration also demands development teams to choose security above speed and creativity. In conclusion, AI-based security transforms CI/CD pipeline protection in fast-paced software development. AI can improve security while preserving agility by automating security procedures, allowing real-time threat detection, and supporting compliance.
