Hospital effluents can be especially hazardous and toxic due to their content of chemical, pathogenic and bio-hazardous wastes. Many of these toxic pollutants are not fully removed or neutralized by traditional municipal wastewater treatment plants, which are primarily designed to address parameters such as Biochemical Oxygen Demand (BOD), Total Suspended Solids (TSS), etc. They are also not easily removed by filtration, settling or flocculation. The common disposal of liquid waste from hospitals into the municipal network collection system or in cesspits is of serious concern and it requires swift and effective address. Wastewater from hospitals contains pollutants that are hazardous and require on-site management to prevent contaminating the city’s sewage system and other surface waters. Unlike industrial operations that typically have a few large volume waste streams; hospitals generate different volumes of a wide variety of wastes and emissions. Most important chemicals in hospital wastewater are disinfectants (due to their major use in hospital practice), antibiotics, cytostatic agents, anesthetics, heavy metals (silver, chromium, zinc, lead, copper, platinum, and mercury), rare earth elements (gadolinium, indium, and osmium) and iodinated X-ray contrast media. Pollution prevention strategies and Best Management Practices (BMPs) to pollutant load reduction at the source is the best solution available to overcome this problem. The pollutant load reduction can be initiated by applying pollution prevention strategies and Best Management Practices (BMPs) to practices that use these chemicals. The goal of pollution prevention in healthcare environments is the same as throughout industry do to eliminate and/or reduce pollution at the source. The major difference when undertaking pollution prevention at healthcare facilities is that they do not manufacture a ‘product’, operate a fabrication ‘process’ or generate waste materials that can be readily recycled, reused or reprocessed. Therefore, the role of Pollution Prevention Strategies, Best Management Practices and Cleaner Production will be somewhat different than other industrial sectors. Pollution Prevention Strategies, Best Management Practices and Cleaner Production applicable to hospital wastewater management in Sri Lanka and Bangladesh are addressed in this paper.

Groundwater (GW) depletion and recurring floods have become a major concern among researchers and planners across the world. To rejuvenate stressed aquifer and moderate flood impacts, a modified version of managed aquifer recharge (MAR) consisting of a cluster of ten recharge wells (RWs) embedded in a community pond with an area of 2625 m2 and utilizing diverted floodwater was tested on a pilot scale in Ramganga sub basin, India. The approach could recharge a maximum of 72426 m3 of floodwater in 78 days during the wet season. The pond intervention minimized clogging of RWs by retaining maximum silt load of 68.01%. Hydro-geochemically, majority of water samples were of Mg-HCO3 and Ca-HCO3type. Ion exchange processes and weathering of carbonate and silicates were the controlling factors, determining water quality of the area. Total dissolved solids, fluoride, iron, zinc, manganese, chromium, cobalt, nickel, mercury, phosphate, nitrate, and ammonical nitrogen were found within the permissible limits as laid down by World Health Organization except arsenic and lead, which seems to be the inherent problem in the area, as evidenced by water quality analysis of farmers tube wells located upstream and down streams of the recharge site. The coliform presence in the 88.23% of sampled GW may thwart from direct use for drinking whereas it was fit for irrigation. Looking the benefits of modified MAR as a proactive GW quality improvement with good aquifer recharge, it is recommended for scaling up of the intervention across the GW stressed parts of the whole Ram Ganga basin and similar hydro-geological regions elsewhere.

Exposure to metals has been hypothesized as possible cause of chronic kidney disease of unknown cause (CKDu) in Sri Lanka; however, evidence is inconclusive. We measured the concentrations of nephrotoxic metals (As, Pb, and Cd), as well as Se in rice (a staple grain in Sri Lanka) and other grains consumed in CKDu endemic and non-endemic regions using Inductively Coupled Mass Spectrometry (ICP-MS). Our results showed comparable mean concentrations (in µg/kg) of 24.5±18, 7.3±6.4, and 14.2±15 for As, Pb, and Cd, respectively, in rice from endemic regions and 17.7±4.7, 12.7±6.8, and 17.8±16 in rice from non-endemic regions. Selenium concentrations (in mg/kg) were 0.05±0.02 in rice cultivated in both endemic and non-endemic regions. Arsenic and Cd concentrations were significantly higher in rice compared to other grains, which themselves had higher Se than rice. All samples were below the Codex standards established for Cd (400 µg/kg for rice; 100 µg/kg for cereal grains), Pb (200 µg/kg) and inorganic As (200 µg/kg) for white rice. Our findings show that dietary exposure to low levels of As, Pb, Cd, and inadequate Se in staple grains cannot be clearly linked to CKDu, suggesting that the disease could be multifactorial. Additional research is needed to determine the contribution of other risk factors such as lifestyle habits and heat stress to plan preventive strategies for reducing CKDu health cases in Sri Lanka.
