“…Seasonally, EC was lower in spring and summer than in autumn and winter seasons. Spring-summer minima were due to nutrient assimilation by autotrophs [67]. The lake exhibited higher value of EC which reflects the high degree of anthropogenic activities such as waste disposal and agricultural runoff.…”

Multivariate techniques, discriminant analysis, and WQI were applied to analyze a water quality data set including 27 parameters at 5 sites of the Lake Wular in Kashmir Himalaya from 2011 to 2013 to investigate spatiotemporal variations and identify potential pollution sources. Spatial and temporal variations in water quality parameters were evaluated through stepwise discriminant analysis (DA). The first spatial discriminant function (DF) accounted for 76.5% of the total spatial variance, and the second DF accounted for 19.1%. The mean values of water temperature, EC, total-N, K, and silicate showed a strong contribution to discriminate the five sampling sites. The mean concentration of NO 2 -N, total-N, and sulphate showed a strong contribution to discriminate the four sampling seasons and accounted for most of the expected seasonal variations. The order of major cations and anions was Ca 2+ > Mg 2+ > Na + > K + and Cl − > SO4 2− > SiO 2 2− respectively. The results of water quality index, employing thirteen core parameters vital for drinking water purposes, showed values of 49.2, 46.5, 47.3, 40.6, and 37.1 for sites I, II, III, IV, and V, respectively. These index values reflect that the water of lake is in good condition for different purposes but increased values alarm us about future repercussions.

“…This is attributed to the release of wastewaters from house boats especially during summer. Low values of EC, PO 4 -P, NH 4 -N and NO 3 -N during summer could be attributed to the higher rate of assimilation by biota due to their peak growth [18]. BOD 5 and COD ranged from 2.07 mg/l at S2 during autumn to 4.47 mg/l at S1 (Hazratbal basin) during summer and 18 mg/l at S2 during summer to 31 mg/l at S1 during winter respectively.…”

Seasonal variation in surface water quality of Dal Lake was assessed using multivariate statistical techniques. Water quality data collected from 4 sampling sites during 4 seasons was analysed for 13 parameters. Significant variation (p<0.05) in temperature, pH, EC, Ca, Mg, Na, K, DO, BOD 5 , COD, PO 4 -P, NH 4 -N and NO 3 -N of sampling sites during different seasons was observed. Cluster analysis grouped 4 sampling sites during 4 seasons into three clusters of similar water quality as relatively less polluted (LP), medium polluted (MP) and highly polluted (HP) sites. The principal component analysis/factor analysis applied to extract and recognize the factors responsible for water quality variations in four seasons of the year resulted in three principal components for each season accounting for 75.78%, 83.25%, 87.33% and 78.96% of total variance for winter, spring, summer and autumn seasons respectively. Parameters like NH 4 -N, NO 3 -N, BOD 5 and COD have strong positive loading whereas temperature and dissolved oxygen has strong negative loading. Thus, from the principal component/factor analysis it is clear that the domestic wastewaters, agricultural runoff and catchment geology play significant role in water quality variations in the Dal Lake for all the four seasons.

“…All these consequences have promoted the use of phytoremediation for the removal of toxic pollutants, because aquatic plants grow and flourish naturally in drainage canals [2]. Phytoremediation, using aquatic plants such as Reed plants, provides a chance for its use as a feasible non-destructive technology to eliminate pollutants from soils or water ecosystems.…”

Water pollution has been a growing issue for the last decades. This is mainly because of the boost in human population, and the motivations that lead to technological advances for the welfare of the society. Water pollution originates from different sources such as agricultural, municipal, industrial, and landfills drainage waters. These pollutants, which are either organic, nutrient, or heavy metals pollutants, are very deleterious to the natural ecosystems and eventually harmful to humans. Different procedures have been proposed for handling heavy metals water pollution, which encompass electro-osmosis, ion exchange, electrokinetic, sludge activation, as well as phytoextraction. Water contaminants are also removed using flotation, membrane filtration, aeration, precipitation, coagulation-flocculation, ion exchange, and electrochemical treatment. These procedures are costly and have prompted the use of other techniques, such as phytoremediation. Phytoremediation involves the utilization of plant species to alleviate the impacts of environmental pollution. It could be implemented to eliminate pollutants from various natural ecosystems including water, soil, and air or to develop new vegetation growth on disturbed or barren ground. Different plant species have been used for phytoremediation. This chapter addresses trace elements pollution of natural water resources in details and the abilities of Aquatic plant communities such as Reed plants (Phragmites australis) to absorb soluble trace elements from water.

Phytoremediation to remove nutrients and improve eutrophic stormwaters using water lettuce (Pistia stratiotes L.)

Abstract: The results from this study indicate that water lettuce has a great potential in removing N and P from eutrophic stormwaters and improving other water quality properties.
