“…In this research all of these dependent parameters were calculated except to turbidity and fecal coliform. The calculation of new weight score is agreed with Effendi et al [79] and Radwan et al [80] as the total remain is one. The used dependent parameters being used are DO, pH, BOD, T°C, TP, NO3 and TDS (is used instead of TS) with new modified values of 0.206, 0.144, 0.144, 0.134, 0.134 and 0.104, respectively.…”

The study focused on the comparison between water quality and its suitability for irrigation in three important drains (El-Serw, Hadous and Bahr Elbaqar Drains), East Nile Delta of Egypt using different indices and factors. The analyses of various water parameters namely; physiochemical parameters (pH, T°C, EC and TDS), organic indicators (OM, DO, BOD and COD), soluble anions (CO3, HCO3, Cl and SO4), cations (Na, K, Ca and Mg), Nutrients (TP, TN, NH4, NO2, NO3, SiO4 and PO4) and metal ions (Fe, Ni, Cd and Co). The data were supported by different statistical analyses (Principal Component Analysis (PCA) and Box plots). Sodium adsorption ratio values give indication to unsuitability for use in the three drains. Water quality index values are more than 100 in three drains meaning unsuitability for use, which attained value of 106.47, 136.87 and 176.63 for El-Serw, Hadous and Bahr El-Baqar drains, respectively. The National Sanitation Foundation-water quality index NSF-WQI also categorized water into medium for El-Serw drain and bad for Hadous and Bahr Elbaqar drains. The permeability index (PI) showed a moderate class for each drain. The potential salinity (PS) give indication to unsatisfactory for use. The Kelly index (KI) and percent sodium Na% give indication to unsuitability except the magnesium hazard that ranked water as good where magnesium percent in the normal range. Heavy metals concentrations of Fe, Ni and Co are within the limits of Environmental Protection Agency (EPA 2002) except for Cd that exceed those limits, this is may be attributed to the high usage of phosphatic fertilizers and pesticides especially in Bahr Elbaqar drain.

“…Changes in hydro-climatic, biological, and chemical factors of the aquatic ecosystem have affected the distribution and abundance of Phytoplankton communities which indicate the water quality 6 . Since Phytoplankton communities are generally more sensitive to pollution, therefore, they are the best biotic indicators of pollution in the aquatic habitat 7 .…”

Biodiversity is one of the important biological factors in determining water quality and maintaining the ecological balance. In this study, there are 223 species of phytoplankton were identified, and they are as follows: 88 species of Bacillariophyta and were at 44%,70 species of Chlorophyta and they were at 29 %, 39 species of Cyanophyta and they were at 16 %, 12 species of Euglenozoa and they were at 4 %, four species of Miozoa and they were at 3 %, and, Phylum Charophyta and Ochrophyta were only eight and two species, respectively and both of them were at 2%. The common phytoplankton recorded in the sites studied include Nitzschia palea, Scenedesmus quadricauda, Oscillatoria princeps, and Peridinium bipes, These species recorded a significant positive correlation with Ec, Sio3, and WT. Phytoplankton including Gomphosphaeria semen-Vitis, Dicloster acuatus, Tetrastrum heteracanthum, and Dictyocha fibula, recorded a significant positive correlation with NO3, PO4, DO, and PH. Water temperature ranged between 14.200 -33.900 ºc in Al-Mansoury and Al-Sada respectively. Electrical conductivity ranged between 2.790 -11.900 ms/cm in Al-Sada and Al-Mansoury respectively. PH ranged between7.750-8.600 in Al-Dawody and Al-Mansoury respectively. Dissolved Oxygen (DO) ranged between 5.950 -13.000 mg/l in Al-Dawody and Al-Mansoury respectively.WT recorded negative correlation with pH (r= -0.591), NO3 -2 (r= -0.463) and DO (r= -0.603). Nitrate ranged between 0.570-12.200 µg /l in Al-and Al-Sada respectively. Phosphate ranged between 0.003-0.154 µg/l, in Al-Dawody and Al-Mansoury respectively. Silicate ranged between 51.200-198.600 µg /l in Al-Baraka and Al-Dawody respectively. Shannon -Weiner index (H`) ranged between 2.275-3.162 in Al-Dawody and Al-Mansoury respectively. Simpson index ranged between 0.856-0.950 in Al-Mansoury and Al-Sada respectively, while the Evenness index was 0.514-0.933 in Al-Dawody and Al-Baraka respectively. Shannon-Weiner index (H`) recorded a significant positive correlation with the Simpson index .

“…Lake Edku is the third largest northern Egyptian coastal lake in the Nile Delta in the Beheira Governorate and one of the most threatened aquatic environments in Egypt due to anthropogenic activities and pollution (Emam et al, 2021). Lake Edku suffers from numerous pollutant sources, represented in point and non-point sources due to anthropogenic activities such as agricultural and municipal wastewater, which may represent a significant threat to the aquatic environment (Radwan et al, 2019).…”

Organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) have the ability to bioaccumulate in food chains and bodies. For Lake Edku, hexachlorocyclohexane (HCH) was isometrically arranged as β > γ > α during both seasons and seasonally arranged as spring> summer. The β-HCH was the most dominant isomer that can be attributed to the biodegradation of α-HCH and γ-HCH to β-HCH. Total Cyclodienes were arranged as Aldrin> Dieldrin> Endrin, and seasonally as spring> summer. The average contributions of DDT congeners mixture detected in Edku Lake waters were in the order of o,p′-DDD> o,p′-DDT> o,p′-DDE> p,p′-DDE>p,p′-DDT > p,p′-DDD during spring and o,p′-DDT> o,p′-DDE> o,p′-DDD> p,p′-DDE and p,p′-DDT > p,p′-DDD during summer; total DDTs recorded higher values during the summer compared to spring. Seasonal distribution is referred to the fact that PCB 28> 52>138> 101> 118> 153> 180 during both seasons. α-HCH/γ-HCH indicated the dominance of lindane. β-/(α+γ)-HCH ratio suggested the recent HCH input for station VI and past input for most stations. DDE/DDD ratios indicate anaerobic and aerobic degradation. (DDE + DDD)/∑DDTs ratios suggesting past input for DDT for most stations during both seasons. o,p′-DDT/p,p′-DDT ratio indicates that stations (I and VIII), as well as station VIII during spring and summer, respectively, recorded technical grade DDT, while the rest of the stations recorded dicofol-type DDT. While, the risk quotient recorded very high risk, except for α-HCH which recorded a moderated risk at some stations. Upon comparing the results of the current study with water quality standards, it was noted that some OCPs and PCBs recorded values higher than the criteria continuous concentration (CCC), while others were higher than the criteria maximum concentration (CMC) during spring and summer.
