“…In addition, the studies reported that the coastal aquifers (southern Sindh) are overexploited; this may possibly lead to the saline intrusion, which increases Na and Cl concentrations in the coastal aquifers [46,47]. Elevated chloride in surface water contamination may be due to wastewater from industries (specifically sugar mills in South Sindh) and effluent from large drains in both zones (e.g., right bank outfall drainage and left bank outfall drainage) [46][47][48]. We were unable to find similar studies, but studies in similar geographic locations showed little variation in the chloride concentration in drinking water [40,49].…”

Primary school children in the developing world often lack potable water, which may result in a high burden of water-related diseases and poor school performance. The present study aimed to characterize the drinking water quality in primary schools of Pakistan. We used a multistage random-sampling method to select 425 primary schools from selected districts of Sindh province. Standard methods were used to characterize water quality. The results were compared with maximum acceptable values recommended by the Pakistani National Environmental Quality Standards (Pak NEQS) and the World Health Organization (WHO) drinking water quality standards. Groundwater (62%) and surface water (38%) were identified as two major drinking water sources in the selected schools with varying levels of water quality. Among all parameters, dissolved oxygen (DO), pH, and nitrate remained within WHO and Pak NEQS water quality standard limit, while total dissolved solids (TDS) (33%), electrical conductivity (EC) (46%), chloride (34%), turbidity (27%), and hardness (11%) samples exceeded standard limits. All dissolved salts had moderate to strong positive correlations with TDS and EC values. Based on a water quality index (WQI), 74% of primary schools had access to excellent or good quality drinking water compared to 26% of schools that had access to either poor, very poor or unsuitable drinking water. Among all three regions, more schools from South Sindh had either poor, very poor or unsuitable drinking water (33%) compared to the Central (25%) and North zones (15%). Hence, water from these locations is unfit for human consumption and these schools need better water quality management plans to stop the spread of water-related diseases in primary school children.

“…During the processing nearly 1000 L of wastewater is produced for every ton of cane crushed. High oxygen demand sugar industry waste water lead to the depletion of dissolved oxygen content in the water bodies if discharged untreated, resulting in rendering the water bodies unfit for both aquatic and human uses (Qureshi et al, 2015). If untreated wastewater is discharged on land, decaying organic solids present in the wastewater clog the soil pores (Reddy et al, 2015).…”

Sugarcane is valuable crop of India and has a major role in foreign exchange. The aim of research work is to investigate the reduction of chemical oxygen demand and color from sugarcane industry effluent by thermolysis and coagulation method. The complete study was done in batch mode to determine the effect of operating parameters. The result shows maximum 73% of chemical oxygen demand and 76% color removal with copper oxide catalyst at 5 kg/m 3 massloading, 85°C reacting temperature, 9 h treatment time and pH 8. Combined study showed 97.6% chemical oxygen demand and 99.9% color removal at pH 6.5 and mass loading 8 mM with copper sulfate salt. The settling and filtration was found to be good at 65°C and 75°C with copper oxide treated sugar industry wastewater.

“…It has been found that the increasing population is the main cause of the deterioration of surface and sub-surface water [15]. Major human activities have polluted fresh water sources [16]. In the future, global population growth is likely to occur mainly in the urban areas [17].…”

The demand and supply of safe water is a basic need. The consumption of clean water intensified with population growth and economic development which in turn cause degradation of available freshwater resources while creating huge volumes of wastewater, solid waste, and serious environmental problems. This paper presents the impact of disposing of domestic/industrial effluents into an irrigation canal. The subsequent contamination of the canal water becomes a public health risk. The non-perennial Phuleli canal with a discharge of 15,026 cusecs, takes in water from the left bank of Kotri Barrage, which is the last controlling hydraulic structure on the Indus River. This canal runs from the periphery of Hyderabad, Tando Muhammad Khan (TM Khan) and Matli cities and supplies water for domestic, agricultural, and industrial activities. The canal water is the only source of drinking water for millions of people because the groundwater in the command area of the canal is highly saline. The banks on both sides of the canal have encroached in cities’ areas. The huge volume of solid waste and municipal and industrial wastewater from these cities and from the occupied canal banks are dumped directly into the canal without any treatment. The collected samples’ were analyzed for pH, EC, TDS, Cl, SO4, HCO3, hardness, Na, K, Ca, and Mg. These results show higher than permissible limits as per NEQS and WHO. The Karl Pearson matrix correlation of parameters reveals strong relation among EC with TDS and CL with SO4, Mg with K and moderated relationship among the other parameters except for pH and DO. Water Quality Index (WQI) model indicates that the water quality of the canal is poor and unfit for drinking. Hence the consumption of canal water is a high potential health risk for locals.
