This article presents the results of a transboundary water quality monitoring program at the two Nogales area in the Arizona-Sonora border region. The program was carried out jointly in 1990 by U.S. and Mexican institutions. The results show pollution problems due to deficiencies in Nogales, Sonora municipal sewerage system, causing not only sewage spills in several parts of the city but also c...

In Ireland, the land application of biosolids is the preferred option of disposing of municipal sewage waste. Biosolids provide nutrients in the form of nitrogen, phosphorus, potassium and increases organic matter. It is also an economic way for a country to dispose of its municipal waste. However, biosolids may potentially contain a wide range of pathogens, and following rainfall events, may b...

The three processes of urbanization, industrialization and globalization are positively correlated with municipal solid waste generation and energy consumption in global urban centers. Heavy reliance on fossil fuels in most world cities has contributed not only to global warming and climate change, but also to astronomical increases and volatility in the prices of energy sources. Africa has suf...

in iraq, waste generation was increased after 2003 war events due to intensepopulation developmentand economic growth. the limitation of designable system for municipal solidwaste (msw) management led toserious problems regarding environment and human health. sanitary landfill in the south of kirkuk is the first kindof effective system for municipal solid waste management in iraq. in the first ...

We assessed impacts on water use achieved by implementation of controlled experiments relating to four water conservation strategies in four towns within the Ipswich watershed in Massachusetts. The strategies included (1) installation of weather-sensitive irrigation controller switches (WSICS) in residences and municipal athletic fields; (2) installation of rainwater harvesting systems in resid...

Understanding water consumption is an important component of management. However, data are limited and coefficients do not account for variability through time across users. This study combines federally maintained discharge with state-maintained withdrawal at monthly steps to estimate facility-level spatially aggregated in Virginia between 2010 2016. We evaluate (1) the feasibility using datas...

17α-ethinylestradiol (EE2), a synthetic oestrogen in oral contraceptives, is one of many pharmaceuticals found in inland waterways worldwide as a result of human consumption and excretion into wastewater treatment systems. At low parts per trillion (ppt), EE2 induces feminisation of male fish, diminishing reproductive success and causing fish population collapse. Intended water quality standard...

Chung, Department of Mechanical and Aerospace Engineering, University of Florida, Gainesville, FL 32611, USA e-mail: [email protected] Two concept systems that are based on the thermochemical process of high temperature steam gasification of lignocellulosic biomass and municipal solid waste are introduced.The primary objectives of the concept systems are (1) to develop the ...

Contamination of industrial and municipal water supplies with arsenic (As), selenium (Se), and mercury (Hg) can occur from natural deposits, industrial discharge, runoff from mining, landfill and agricultural operations. Consumption of contaminated water can cause skin damage (As), kidney and nervous system damage (Hg) and numbness in the fingers and toes (Se).1 The U.S. Environmental Protectio...
