“…Dissolved oxygen and oxygen saturation showed similar behaviours, although the water temperature also influenced oxygen saturation indexes. Temperature variation was small, being predominant the interdependence between the dissolved oxygen and its saturation (Nezlin et al, 2009;Shah and Pant, 2012). The oxygen contents were higher in the lower area of the estuary, where there is a greater influence of marine waters, more oxygenated (Tett et al, 2003;Yin et al, 2004;Mudge et al, 2007; FIGURE 8 | Cluster of interannual seasonal averages of water quality parameters and rainfall at the Goiana River estuary through Euclidean distance.…”

Anthropic processes degrade quality of estuarine environments, resulting in a worrying form of water pollution. The objective of the study was to describe and discuss interannual and seasonal changes of water quality based on indicators monitored in Goiana River estuary, as well as identifying the main drivers of such changes. We considered three estuarine areas or habitats (upper estuary, middle estuary and lower estuary), and two seasons (dry and rainy) for anchoring sample design. The information collected for surface and bottom water include water temperature (• C), salinity, dissolved oxygen (mg L −1), saturation (%) and Secchi depth (cm) (n = 864). The monthly total rainfall (mm) was compiled from public database. Multivariate analyses highlight inter dependency among these parameters. Water quality was reduced in dry periods (including episodes of hypoxia), but generally increased toward the mouth of estuary. Rainfall is the most important factor in the renewal and maintenance waters of small tropical estuaries. Regions most sensitive to climate change where water resources are depleted and/or compromised should pay even more attention to upcoming changes in rainfall (seasonal) and climatic patterns in addition to better water management practices.

“…As Tobler's First Law of Geography states, "Everything is related to everything else, but near things are more related than distant things" (Tobler, 2004). Upon further investigation of related literature, Shah and Pant (2012) revealed that the Sirisya river had severely degraded water quality because of the wastewater sewage that it receives from the 250 industrial buildups that surround it. To elaborate, Shah and Pant (2012) stressed that Parsa district was a special economic zone and although chemical parameters such as pH, Ammonia, and total dissolved solids were within standard limits (in their study), grease and oil from the factory effluents severely impacted the water quality which in turn, impacted the health of surrounding residents.…”

<p>The purpose of this major research paper was to gain an understanding of the water crisis that exists in Nepal, specifically, how the quality of water and accessibility to natural water resources differs between three areas. The evaluated areas comprise Kaski, Terai, and Kathmandu. The creation of a water quality index and distance accumulation spatial analysis techniques, indicates that Kaski has the highest quality of water while placing second for accessibility. Terai ranks second for water quality, with the highest number of settlements with natural water accessibility. Kathmandu has the worst water quality and the least number of settlements in proximity to natural water resources. Since such a wide disparity exists, further research needs to be conducted to investigate possible correlations between the aforementioned variables and socioeconomic differences. In doing so, mitigative techniques can be devised to ensure that the Nepali population, regardless of class, have access to clean drinking water.</p>

“…Owing to its paramount significance, numerous investigations concerning the quality of surface water have been conducted in various parts of Nepal, including the Bagmati River in the Kathmandu valley Karn & Harada (2001), Kodku Khola, Lalitpur Maharjan (2006), Sirsiya River of central southern Nepal Shah & Pant (2013), Gosainkunda Lake Raut et al(2013), Bagmati River in Kathmandu Valley Gautam et al (2013), Kolpu Khola in Sisdol Landfill Area of Nuwakot District Shrestha et al (2015), Chimdi in Sunsari district , Pokhara lake , Betana wetland in Morang Das et al (2018), Sanbarish Pond of Morang District Das et al (2020), Lakes of Chitwan National Park, Central Nepal Bhusal & Devkota (2020) and Rara Lake Kaphle et al (2021). Keeping these aspects into consideration, the present study has been designed to assess the Triyuga river water on the basis of physicochemical characteristics.…”

The present investigation has been conducted to assess the status of physiochemical and microbiological parameters to understand the present scenario of water quality at Triyuga River water at Belaka municipality of Udayapur district, Nepal. The temperature ranged from 180C to 200C, the TDS value ranged from 89 mg/L to 112 mg/L and were below the WHO guideline value of 1200 mg/L, the pH values of the surface water sources in the present study were found to be alkaline ranging above from 7.6 to 7.9 were found within the range of WHO guideline value of 6.5-8.5. Similarly the values of dissolved oxygen ranged from 6.4 mg/L to 10.4 mg/L and were above the WHO guideline value of 5 mg/L, the bicarbonate (HCO3) value ranged from 105 mg/L to 125 mg/L and were below the WHO guideline value of 125-350 mg/L, the values of Nitrate ranged from 3 mg/L to 5 mg/L and were below the WHO guideline of 50 mg/L, the values of Nitrite ranged from 0.3 mg/L to 0.5 mg/L, the value of Ammonium ranged from 0 mg/L to 0.3 mg/L, the values of Iron ranged from 1 mg/L to 1.5 mg/L and were above the WHO guideline of 0.3 mg/L and the phosphate was not detected in all the three different sites of surface water samples. The fecal coliform was found to be positive in all the samples and the value of fecal coliform recorded was 15, 15 and 21 MPN/100ml in Site I, II and III respectively.
