In the past two decades, freshwater bodies and their water quality have deteriorated rapidly due to several natural and anthropogenic causes, as well as rapid urbanization and industrialization. Using environmental assessment tools, eight sampling stations were used to assess the water quality of the upper Ganga and its major headstreams between January 2019 and December 2021 and to assess the impact of human-led activities on the environment and the suitability of the catchment basin to perpetuate aquatic ecological diversity. During the current study period, water quality indices such as the Water Quality Index (WQI), Nemerow Pollution Index (NPI), and the Overall index of pollution (OIP) were employed to assess water quality. Twelve physicochemical parameters were examined using appropriate techniques and then compared to international standards. A small increase was observed in some physicochemical parameters, such as pH, Tur-bidity, Dissolved Oxygen, and Biological Oxygen Demand, at sampling stations 7 and 8. In the upper Ganga basin, all three indices (WQI, NPI, and OIP) accurately recorded numerous natural and human events at the selected sample sites. The water quality demonstrated that aquatic species were abundant. The water quality at some sample stations was also

The most important waste stream created during oil and gas production is oilfield-produced water. When discharged without treatment, it poses a significant risk of pollution of marine ecosystems. While adequate treatment before disposal is acceptable, achieving authorized discharge criteria continues to be a problem for the petroleum sector. This research examined the physicochemical characteristics of produced water at various month intervals before and after treatment. Heavy metal and organic component concentrations in water samples were determined using atomic absorption spectroscopy and gas chromatography. The results indicate that produced water from a certain Niger Delta oilfield contains significant amounts of heavy metals and some organic compounds after treatment. The present laws, as well as the measurement of dispersed oil and grease content, have been in place for a long period of time without considerable change, even though most dangerous components in produced water are dissolved. It is recommendable for the prospective field developers/operators to consider the dissolved components of produced water and consider the economic consequences of adopting tertiary produced water polishing technologies.

Water quality data of the Cileungsi-Cikeas-Bekasi River (survey results and monitoring data) were analyzed using the Pollution Index (IP) according to the calculation guidelines listed in the Ministry of Environment Decree No. 115 of 2003 concerning Guidelines for Determining Water Quality Status. The goal was to determine the status of the quality or level of river water pollution. The quality standard used in the calculation refers to the class II quality standard based on the West Java Governor Regulation No. 12 of 2013 concerning Water Quality Standards and Water Pollution Control in Cimanuk River, Cilamaya River, and Bekasi River. The PI value of the Cileungsi River shows that the quality status of the Cileungsi River was in moderate pollution, except in the upstream part (good condition). Status of Cikeas River water quality was still in good condition, except in the downstream segment (light pollution). Based on data from the 2019 survey and monitoring of Environmental Agency (DLH) of Bekasi City in the second semester of 2018, the water quality status of Bekasi River is moderate pollution in all segments.

The Cipeles watershed is the largest subsystem of the Cimanuk watershed, which is located in an agricultural area. Some segments of the Cipeles River are appropriate for aquatic life habitat. To assess the pollutant risk from heavy metals, which tend to accumulate in the environment, this study determined the heavy metal concentrations as a basic database, calculate the heavy metal pollution index (HMPI), and assess the correlation between heavy metals from the surface and pore waters of Cipeles River. Samples from 11 sampling stations at the end of the wet season were collected, preserved, and characterized using inductively coupled plasma mass spectrometry. The heavy metal concentrations were then plotted on a map using a geographic information system. As a result, the heavy metal occurrence in pore water was found to be Mn > Fe > Ba > Co > Zn > Cu > Pb > Cr in the order of abundance, while the order was slightly different in surface water, i.e., Fe > Mn > Zn > Ba > Cu > Pb > Co > Cr. Both pore and surface waters showed similar dominance for iron and manganese, where they mostly originated from the run-off water from the laterite and alluvial soils at the sampling locations. The other micro-concentrations of heavy metals indicate the anthropogenic source of pollutants. The HMPI indicated a low level in the upstream area, medium to high levels in the city center, and high levels in the downstream area. Moreover, there is a significant correlation between the heavy metal concentration at pore and surface waters, especially for Mn and Co in the city area and also Zn and Ba in the downstream area.

The water quality of a Nigerian river was studied between December 2017 and November 2018 in six stations in relation to anthropogenic impacts and suitability to support aquatic biodiversity using water quality indices. The indices used were Water Quality Index (WQI) and Nemerow’s Pollution Index (NPI). Thirteen parameters were evaluated using standard methods and compared with national standard. Some parameters like turbidity, pH, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand and phosphate did not meet the standard especially in station 4. The indices (WQI and NPI) in the six stations effectively captured the effect of the anthropogenic activities in the river and showed that the water quality was suitable to sustain biodiversity. It can be concluded that human activities including sand mining has not negatively impacted the water quality. However, the activities need to be monitored and regulated.

Water quality of natural water bodies is on a rapid decline due to activities and discharges arising from population growth, urbanisation and industrialisation. The water quality of a south eastern Nigerian river was studied between January and June 2018 in 3 stations in relation to anthropogenic impacts and suitability to support aquatic biodiversity using water quality indices. Thirteen parameters were evaluated using standard methods and compared with national standard. Some parameters did not meet the standards; pH and dissolved oxygen in all the stations and biochemical oxygen demand in Station 1. The indices in the three stations effectively captured the effect of the anthropogenic activities in the river and showed that the water quality was suitable to sustain biodiversity. It can be concluded that human activities including effluent discharge did not give negative impact on the water quality. However, the activities need to monitored and regulated.
The abundance of natural fossil fuel in the Niger Delta of Nigeria has instituted generation of oilfield produced water (PW) in large volume. This constitutes environmental pollution when discharged outside the permissible limit given by Nigerian Upstream Petroleum Regulatory Commission (NUPRC). PW can be used for soil irrigation if its constituents are remediated after treatment. This research assessed the physicochemical properties of untreated and treated samples of oilfield PW from Awoba, Imo River and Kolo creek oil fields of Niger Delta using electrometric, argentometric, colorimetric, titration, atomic absorption spectroscopy, APHA and HACH standard methods. Oil-treatment facilities effectiveness was investigated by comparing laboratory results for treated-PW with the permissible regulatory values of NUPRC. The pH, salinity hazard, sodium hazard, boron, chloride, TDS, carbonate and nitrate of treated-PW were measured to check the suitability of treated-PW quality for soil irrigation. Measured values were compared with the permissible standard of US EPA. Sodium adsorption ratio (SAR) and electric conductivity (EC) were used to determine the level of sodium and salinity hazards respectively. The results indicated that none of the untreated-PW samples complied with NUPRC permissible limit. Physicochemical properties of treated-PW revealed samples to be close to or within approved NUPRC standards except in few cases. All the measured parameters of treated-PW from Awoba and Imo River oil fields conformed to the US EPA standard value except their ECs and SAR of Imo River oil field which measured 2.46 and 2.93 ds m−1, and 2.57 respectively. However, all other parameters measured for treated-PW from Kolo creek oil field did not conform to the standard except pH and nitrate which measured 7.7 and 4.86 mg/L respectively. In conclusion, oil treatment facilities should be more robust to degrade a wide range of recalcitrant compounds in PW pollutants in order to minimize the impacts of toxic compounds in PW on the environment.
