“…The rift floor is fully covered by lacustrine sediments and acidic rocks (welded and unwelded tuff, ash flow tuff, pumice and obsidian rich lava) (Chernet, 1982;Legesse et al, 2003). It has also a high concentration of F À (Gizaw et al, 2014), which is of great health concern around the study area and in most parts of the rift system. This accounts for the richness of the drainage waters in dissolved silicon, Na + and K + .…”

Irrigation, regardless of its possible negative impacts on the environment, is the prime choice to combat poverty and sustain food security. Changes in soil physicochemical properties and subsequent loss of productivity are the main challenges associated with irrigation practices. This study investigated the effect of furrow and basin irrigation systems on surface and subsurface soil physicochemical properties in comparison with properties in non‐irrigated fields. The soil properties were analysed as repeated measures using appropriate covariance structure. The results showed significant interaction between irrigation and depth on electrical conductivity, pH, Na+, Ca2+, Mg2+, soluble cations and organic carbon; but only the main effect of irrigation system was significant on K+, HCO3−, Cl−, SO42−, soluble anions and sodium adsorption ratio. Both irrigation systems had lower soluble salt content on the surface than at the subsurface layer with basin irrigation having slightly higher, but the non‐irrigated fields showed the opposite. The soil pH was high, particularly in the non‐irrigated fields, which could affect the availability of important soil constituents like Ca, Mg, Co, Cu, Fe, Mn and Zn, and increase Na hazard and boron (B) toxicity that would impair crop productivity. Therefore, the effects of the irrigation method on the soil properties should be well understood and appropriate precautions should be taken when choosing irrigation methods. © 2018 John Wiley & Sons, Ltd.

“…Some studies have been reported on the mineral composition of lake water, river water, and irrigation waters in Ethiopia [11,34,35]. Physicochemical analysis of drinking water has also been studied to assess the quality of drinking water in different cities and regions of Ethiopia [7,33,36,37].…”

The consumption of bottled drinking water has been increasing in the world. But, the quality of bottled water used for human consumption is not subjected to any stringent quality control measure in Ethiopia. The present study was carried out to determine the physicochemical quality parameters of twenty brands of bottled drinking water available in Addis Ababa and to compare with drinking water guidelines set by World Health Organization (WHO) and Compulsory Ethiopia Standards (CES). The samples were collected by random sampling technique. The physicochemical parameters such as pH; TDS and EC; total alkalinity, total hardness, HCO3 -, Cl -; SO4 2-, NO3 -, NO2 -, F -) and common cations (Ca 2+ , Mg 2+ , Na + , and K + ) were determined by pH meter, conductivity meter, titration, UV-Visible spectrometry, fluoride ion selective electrode and microwave plasmaatomic emission spectrometry, respectively. The mean physicochemical concentration of TDS, total alkalinity, total hardness, HCO3 -, SO4 2-, NO3 -, NO2 -, F -, Cl -, Ca 2+ , Mg 2+ , Na + , K + , pH and EC in bottled water samples were found in the range (4.µs/cm), respectively. The drinking water quality index (WQI) was calculated based on 15 important quality parameters and the results were found in the range 3.85-49.2. The mean concentrations of physicochemical parameters in almost all the bottled drinking water were below the permissible limit set by WHO and CES. Hence, all the tested bottled water samples are safe for drinking purpose.

Ethiop. 2019, 33(1) 22among others) have been the most available sources of water used for domestic purposes. The water from these sources is contaminated with domestic, agricultural, and industrial wastes and likely to cause water-related diseases. Impaired surface water quality always result in an unhealthy socio-economic environment [9]. The levels of chemicals in drinking water are sometimes high enough to cause acute health effects. Polluted drinking water causes many diseases as diarrhea, vomiting, gastroenteritis, dysentery, kidney problems [10].Water quality parameters are the physical, chemical, and biological characteristics of water in association to the set of standards [1,11]. Safe water is to say that drinking water need to be free from pathogenic organisms, toxic substances, an overdose of minerals and organic materials as well as it should be pleasant (free from color, turbidity, odor and taste) [1,12]. Water quality parameters provide important information about the health of a water body. Besides, these parameters are used to find out the quality of water for drinking purpose [2]. The quality of water is the degree of its potability and is determined by the level of physicochemical, microbial and heavy metals (which include suspended and dissolved substances in the water, the degree of alkalinity (pH), temperature, appearance in term of color, taste, odor and the prese...
