Water quality levels of Otamiri River was studied to seek explanations for the variations of water quality indicators in the river and also tried to evaluate the influence of urban land use activities and season on the water quality and to examine the water quality of Otamiri River for agricultural and domestic uses. Water sampling and laboratory analyses were carried out using standard procedures to determine the concentrations of selected parameters in the sample. The data obtained ranged from 21.10 to 98.00µS/cm for Electrical Conductivity, 9.70 to 45.10mg/l for TDS, 5.60 to 20.80mg/l total hardness, 0.00 to 3.06mg/l NO3- , 0.15 to 6.50mg/l PO4, 0.00 to 12.63mg/l SO4 2- , and 14.48 to 32.96mg/l Cl- . Other results ranged from 12.03 to 19.26mg/l BOD5, TSS 40.50 to 1793.50mg/l, turbidity 7.86 to 96.40NTU and pH 6.48 to 6.90 at 29?C. The data clearly show that areas outside the influence of urban activities still maintain their pristine environmental conditions with water quality parameters falling within permissible limits. The water from these areas can sustain aquatic life and are safe for human consumption. However, the results further showed that the midstream area that receive wastes from urban land use activities was polluted with parameters such as NO3- , PO4- , Cl- , BOD5, TDS, and COD being higher than the permissible limit. This demonstrates the influence of urban land use on the water quality of Otamiri River.

Rural Land Use

The study relates groundwater quality to land use types in Lagos State. Fourteen samples were collected from hand dug wells and boreholes, seven each from rural and urban land uses in the study area. Ten parameters (pH, electrical conductivity, total dissolved solids, total hardness, calcium, magnesium, chloride, nitrate and sulfate) were determined using standard methods. The resulting water quality indices revealed that 58.09% of the samples were rated very poor while 21.73%, 9.08% and 11.1% were rated poor, good and excellent, respectively in rural land use. The analysis of samples drawn from urban land use revealed that 76.55% of the water was unfit for drinking while 14.4%, 6.42% and 2.63% were found to be very poor, good and excellent, respectively. pH, total dissolved solids, chloride, total hardness and nitrate were beyond the permissible limits for urban land use while, pH, total hardness and nitrate were above permissible limits for rural land use. These parameters were found to be responsible for the poor water quality rating in the study areas. The paper recommends a comprehensive effective sewerage system for safe disposal of sewage, efficient waste water handling and control of urban runoff to prevent groundwater quality deterioration in the study areas.Keywords: Evaluation; Groundwater; Quality; Land use; Water quality index; Lagos-Nigeria.© 2012 JSR Publications.

Changes in the land use and land cover in areas adjacent to water reservoirs directly affect the quality of this water. This research presents a study on the water quality in the basin of one of the most important public water supply reservoirs in the city of Juiz de Fora, Minas Gerais. The main objective of this study was to analyze the behavior of limnological parameters and the correlation with land use and land cover in the contribution basin of the Doutor João Penido reservoir (CBJPR). The methodology was based on the analysis of water quality parameters, related to water samples collected from 2012 to 2015. Six sampling points were chosen from different locations: spring, medium course, main tributaries of the reservoir and the reservoir catchment. The parameters analyzed were turbidity, total solids (TS), oxygen consumed (OC), dissolved oxygen (DO), electrical conductivity, total nitrogen (TN), total phosphorus (TP), E. Coli, temperature, pH and total dissolved solids (TDS). The Kendall’s tau test was used to analyze the correlations between the parameters of water quality, land use and land cover in the CBJPR. In general, measured parameters showed better results in spring and in reservoir catchment, showing a worse quality of the water along the tributaries and the dilution power of the reservoir. The correlations pointed to the need for protection and preservation of forests in strategic locations to ensure good water quality.

Abstract The effect of different land use types on the physicochemical water quality of a semi-arid coastal basin is examined. From nine sites, a comprehensive sampling campaign was executed during October 2018 to January 2019. One-way analysis of variance (ANOVA), Pearson correlation and multiple regression analyses were used to determine the relationship between water quality characteristics and land use types at the sub-basin and buffer-zone scales. The one-way ANOVA test indicated that most of the parameters are significantly different (p < 0.05) among the sampling sites with the exception of pH, total hardness (TH), nitrate-nitrogen (NO3-N), ammonia-nitrogen (NH3-N), dissolved oxygen (DO), chemical oxygen demand (COD) and iron (Fe). Agriculture and built-up/bare land had a positive relationship with turbidity, TSS, conductivity and Fe within 50 m and 150 m buffer zones. Built-up/bare land showed a positive relationship with turbidity, TSS and Cl at the sub-basin scale. Forest cover correlated negatively with water quality although not significantly. Grassland correlated significantly with temperature, Cl and total hardness. Results of the multiple regression analysis indicate that land use types within the riparian buffer zones had greater impact on water quality than at the sub-basin scale. This work provides essential information for land use planners and water managers towards sustainable water resources management.

Quality Status

The issues of freshwater pollutions and the high demand of clean freshwater for daily human activities have forced developing countries such as Malaysia to continuously monitor the quality of the freshwater. The present study objective is to present the trend of water quality status in the Kelantan River downstream, Peninsular Malaysia from 2005 to 2018. Water samples were collected during dry and monsoon seasons from a sampling station located at downstream of the Kelantan River. Water quality parameters such as temperature, pH and dissolved oxygen (DO) were measured in situ while other parameters were analysed in the laboratory based on retrieved water samples. Water quality status was determined based on National Water Quality Standard (NWQS) for River in Malaysia by calculating the water quality index (WQI) according to the concentration of six water quality parameters involving pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), suspended solids (TSS) and Ammonia Nitrogen (AN). The results showed that Kelantan River had good water quality during the dry season classified in Class II at 2005. The water quality was found to be slightly lower during the monsoon season in year 2006. In addition, increasing the number of construction, human activities in the land use areas, land use changes and the sewage water from domestic, industrial, wet market and food outlets in the Kelantan State have declined the water quality in Kelantan River from Class II (in 2005) to Class III (in 2010 and 2011) and to become Class IV in 2017 to 2018. The results of the present study are expected to give valuable information for the water managers in order to deal with better strategies in controlling the quality of freshwater at the Kelantan River and minimize the incidence of pollution-oriented problems, thus the water can be utilized for various water uses with appropriate quality.

A má qualidade dos corpos de água exerce influência direta sobre a saúde da sociedade, podendo causar doenças de veiculação hídrica, que levam a morte milhões de pessoas no mundo. Neste cenário, o presente estudo objetivou identificar as relações existentes entre condições ambientais e doenças de veiculação hídrica no Assentamento Rural Serra Grande, situado na sub bacia hidrográfica do Riacho Natuba, no município de Vitória de Santo Antão, em Pernambuco. Foram escolhidas seis nascentes, fazendo-se medições de parâmetros de qualidade de água, comparando-se os resultados das análises com os padrões estabelecidos pela Resolução Conama Nº 357/05 e Portaria do Ministério da Saúde Nº 2914/11. Para identificar a ocorrência de doenças de veiculação hídrica no assentamento procedeu-se a aplicação de questionários junto à comunidade local, representantes do Posto de Saúde e da Secretaria de Saúde Municipal, abordando aspectos sobre a incidência dessas doenças e respectivos programas de saúde implementados. Os resultados obtidos mostraram que as nascentes representavam a principal fonte de água para o consumo doméstico, a irrigação e a dessedentação animal. No entanto, as análises de qualidade de água apontaram que a mesma não apresentava condições apropriadas ao consumo humano direto, requerendo prévio tratamento. Em relação ao perfil de ocorrência das doenças de veiculação hídrica, constatou-se que as verminoses e protozooses são as doenças que mais acometem a população.   A B S T R A C T The poor quality of water bodies shall exercise direct influence on the health of society, causing hydro term placement diseases leading to death millions of people worldwide. In this scenario, the present study aimed to identify the relationship between environmental conditions and hydro term placement diseases in the Rural Settlement Serra Grande, located in the Sub-basin of the Natuba rivulet, in the municipality of Vitória de Santo Antão, Pernmbuco State, Brazil. Six springs  were chosen for sample collections and determination of  water quality parameters, comparing the results with the quality standards established by CONAMA ( Brazilian National Environmental Council) Resolution Nº 357/05 and Ordinance of the Ministry of Health (Brazil) No. 2914/11. Questionnaires were applied to local social actors: community, health and Municipal Health Secretariat, addressing aspects of water diseases and health programs implemented. The results obtained showed that the springs were the main source of water for domestic consumption, irrigation and animal watering in the studied area. However, the water quality analyses showed that these springs  do not show appropriate sanitary conditions to direct human consumption, requiring treatment. In relation to the profile of hydro term placement diseases occurrence, it was observed that the worms and protozooses are the diseases that most affected the local population.

In this work, a set of physical, chemical and biological parameters were analysed for Khirisan river from the period extending from December 2017up to November 2018. The samples were selected from three different sites, agricultural, commercial and residential area to assess the water quality of the river for drinking and irrigation purposes. The study showed that a number of diversity factors were recognized which have a direct effect on the quality of Khirisan river. This includes the catchment feeding area of the river, untreated domestic sewage from the restaurants, cafeterias and government buildings which are adjacent to the river. Water quality of Khirisan river, according to the Iraqi and international standards, satisfies the limits of the rules of the drinking purposes for all studied parameters except the values of calcium ions and total hardness value for some rainy months as well as to organic load. The mean values of BOD5 and COD for the three sites were 7.7 and 36 mg/l. In terms of irrigation purposes, the water quality of the river can be considered low to medium damage in terms of salinity and sodium hazards. In terms of chloride risk, there are no toxicity problems to the roots and leaves of the plants. Therefore, it requires a continual intensive water quality monitoring program to reduce its impact.

The water quality and concentrations of selected heavy metals (cadmium, lead, and zinc) in Saba River, Osogbo were assessed monthly over a period of six months with a view to providing information on the water quality of the potentially polluted urban river system. Three sampling sites were selected along the Saba River (the upper reach of the river (Station A), mid-point of the river (Station B) and the lower reach of the river where it emptied into River Osun (Station C)). The recorded ambient air and water temperature, pH, alkalinity conductivity, total hardness, BOD and COD, as well as the phosphate and nitrate levels of Saba River, were within the maximum allowable regulatory limits of WHO (2011). The dissolved oxygen level between March and April in all the sampling points were in the limit of putting aquatic life under stress (<5.0 mg/L). Also the alkalinity level in station B between February and June, and in Station C from February till May were however above the maximum allowable desirable range of EPA (2001) and WHO (2011). The concentration of zinc, which ranged from 717 to 1,000 µg/L, was the highest amongst the selected metals assayed in the water. However, the mean concentration of lead in the water samples collected from Stations B and C (26 µg/L and 24 µg/L, respectively) was found to be above recommended regulatory acceptable limits of 20 µg/L of WHO (2011) and FEPA (2007). The study concluded that the physico-chemical indices of the water quality indicated that the river was mildly polluted.

Use of geostatistical approaches for water quality mapping is a smart and timely approach to assess the quality of groundwater and evaluate its suitability for irrigation purpose. Present study was undertaken to map the spatial distribution of different water quality parameters and generate water quality map for Mansa district using geo-statistical interpolator (Kriging). Geo-referenced groundwater samples were collected and analysed for different quality parameters i.e. pH, Electrical Conductivity (EC), Carbonate and Bicarbonate (CO 3 2- , HCO 3 - ), Chloride (Cl - ), Total Hardness (Ca 2+ +Mg 2+ ) and Sodium (Na + ) content; and Residual Sodium Carbonate (RSC) was calculated. Salinity and alkalinity hazards were evaluated using national and international standards and the overall, water quality was assessed to judge its suitability for irrigation purpose. Quality of groundwater for irrigation was found to be marginal in major part of district Mansa covering an area of 200156.7 ha (92.3% of its Total Geographical Area) which can be used for irrigation purpose only after some amelioration. Extreme salinity (ECandgt;4 dSm -1 ) and alkalinity (RSCandgt; 5 meq l -1 ) hazards were prevalent only in small patches in Sardulgarh and Budhlada blocks covering 26.7 and 2.9% of TGA of the respective blocks. Mixing of canal water with groundwater, use of suitable amendments, like gypsum, selection of appropriate crops and cropping systems should be in regular practice for improving the water quality in one hand and preventing further deterioration in other.
