Abstract

Waste generated from healthcare activities usually comprise a broad variety of materials ranging from used needles, syringes, to soiled dressings. This list also includes body parts, diagnostic samples, blood, chemicals, pharmaceuticals, medical devices and radioactive materials. In the education sector too, solid waste management has become a topical issue necessitating prompt attention and appraisal. Educational waste basically are categorised into recyclable, general and biodegradable waste forms. This study presents evaluation of solid waste issues towards achieving sustainable facilities management (FM) success in the Nigeria built environment. In this investigation, structured surveys were directed to the building services, estate, and environmental management experts as well as facilities managers operating within these targeted sectors: hospitals and universities (schools) to collect solid waste management data. Issues that influence and support good sustainable FM regarding waste management practices were also sought in the administered surveys. A functional unit size of 100m2 within the investigated facilities was considered in each case as a common basis for comparisons with the achievable results between the studied hospitals and schools. The outcomes from these studies and recommendations for best practices in future examinations are presented.

Abstract

Quaternary glacial till, outwash, lake sediments, and loess compose the surficial deposits of McHenry County, Illinois. Much of the landscape of McHenry County were formed by at least three separate advances of the Harvard Sublobe of the Wisconsin Episode Lake Michigan Lobe, which was part of the Laurentide Ice Sheet. This project focuses on the delineation of the stratigraphy and extent of the Pearl-Ashmore Aquifer. The Pearl-Ashmore Aquifer is the combination of the proglacial outwash of the Wisconsin Episode Ashmore Tongue of the Henry Formation and the youngest outwash associated with the Illinois Episode, which is the Pearl Formation. A 3-D geologic model was generated from a number of different subsurface geologic data sets, including geologic borings, and municipal and private water well records. These data were initially visualized and interpreted in the 3-D environment using ESRI’s ArcScene. More than 700 wells were used to construct the model. The stratigraphic picks were imported into Petrel, and horizons were created from the surface data to complete the 3-D geologic model. Isopach maps of each unit were then created. The Pearl-Ashmore Aquifer extends through the eastern two-thirds of McHenry County. The 3-D geologic model predicts that the aquifer has an average thickness ranging from 5 to 15 m and is thickest in the north-central portion of McHenry County where it can reach thicknesses of up to 40 m.

Abstract

This study presents physicochemical characteristics (NO3-, SO42-, CO32-, suspended particulate matter, CO and pH) in air from Qua Iboe Estuary investigated as a result of the gas flare site located in Mkpanak, Ibeno in coastal area of Akwa Ibom State, Nigeria. Air and rainwater samples were collected during the dry and wet seasons in (2011-2012) and analyzed for the above physicochemical species using standard methods. Mean and standard deviation were used to assess the impact of these species in the region. Results obtained revealed that the mean concentrations of NO3- (44.77mg/m3 and 19.95 mg/m3) and SO42- (7.54 mg/m3 and 4.53 mg/m3) in dry and wet seasons were very low and were within the safety limits, suggesting minimal or no adverse effects on the environment. However, the mean concentrations of CO32-(2777.46 mg/m3 and 2859.69 mg/m3, CO(60.29 mg/m3 and 32.65 mg/m3) and pH (5.98 and 6.68) in dry and wet seasons respectively, were higher than the acceptable ambient air limits specified by the Federal Ministry of Environment (FMEnv) and Department of Petroleum Resources (DPR), Nigeria. Based on these findings, it can be concluded that within the studied region, the activity of constant gas flaring is one of the major sources of high concentration of these physicochemical species, with significant implications for the sustainability of the environment and life forms in this area. Recommendations are made to address these issues as best practices are presented.
