[AHW23-P18] Assessment of Synergy between Biomedical Waste and Shallow Groundwater Pollution
Keywords:Groundwater, Biomedical waste, MCMC methods, Environmental awareness
Data about the sources, quantity produced, treatment facilities, and awareness of biomedical waste, collected by questionnaire method based survey revealed that the mean waste generation was 8.08 kg/day with SD 5.371 kg/day. The biomedical waste consisted of approximately 1.2 % of the total municipal waste generated by the city and the patients affected with waterborne diseases were about 36 % of the total patients recorded. A latin hypercube Pareto distribution coupled with AMALGAM algorithm was employed for the initial sampling states of the proposals from the observed data (no. of patients). Thereafter, posterior estimates were generated using the Markov Chain Monte Carlo (MCMC) methods which showed a close fit with the observed and simulated data with RMSE 0.158. Furthermore, regression analysis with R2=0.868 construed strong positive linear correlation between two variables viz. the number of patients and biomedical waste generated (and dumped). Recommendations are made for prioritizing the waste segregation and employing the indispensable management processes including waste treatment to avoid the further deterioration of the drinking water quality. The hospital authorities are advised to conduct the periodic seminars for enhancing awareness among the workforce from present 93.3 % to a maximum possible level.
