After building of Grand Ethiopian Renaissance Dam (GERD), 
significant drastic shortage in Nile water resources in Egypt 
is predictable. This situation of water shortage would force 
Egyptian farmers to use low quality water resources impreg-
nated with a variety of contaminants that will inserted in 
food chain. In a complete randomized plot design green-
house experiment, soil samples collected from Abou-Rawash, 
Sinai and Kafr El-Shekh Governorated irrigated with varied 
types of low quality waters for extended periods were trailed 
for the sake of valuation of new innovative phytoremedi-
ation practices. In the used three soil ecosystems, the Zn 
equivalent parameter, that indicates the safety of cultivation, 
ranged between 340 and 630, while the safe level should not 
exceed 250. Integrated management practices were applied 
using canola and Indian mustard hyper accumulator plants, 
in association with Acidithiobacillus thiooxidans and Arbus-
cular Mycorrhiza (AM) after furnishing the soil ecosystem 
with the chemical stabilizer of PTE’s probentonite. Results 
indicated that the canola hyper accumulator plant was more 
efficient than Indian mustard plant especially in Ni uptake 
compared to Cu or Zn uptakes. In addition, the introduction 
of Acidithiobacillus thiooxidans and AM to the contaminated 
soil ecosystems significantly enhanced the uptake of PTE's. 
The kinetic parameters of both theoretical and empirical 
models confirmed that the mixture of all remediative amend-
ments was the best in minimizing Zn equivalent value to a 
save level. The different mechanisms that might take place 
between the applied remediative amendments and PTE’s in 
the three contaminated soil ecosystems were discussed.

Sewage effluent samples were monthly collected during the 
period from January to July 2012 from the main canals of 
Konbora (Abu-Rawash site) and Zenine (El-Motamadia site) 
that are frequently used in irrigating different eaten raw field 
and horticulture crops. Nile water samples were periodically 
collected from El-Khanater El-Khayria as standard irrigation 
water. The chemical characterization of sewage effluent and 
Nile water samples included pH, conductivity, SAR, solu-
ble cations as well as potential toxic elements (PTEs) using 
standard analytical methods. Results confirmed significant 
variations in these studied chemical parameters between the 
two studied sewage effluents. A significant increase in EC, pH 
and SAR values in both sewage effluents samples compared 
Nile water, representing save levels for irrigation water ac-
cording to FAO standards, were noticed. The content of PTE’s 
in both sewage effluents  showed that the concentrations of 
Cd2+, Cu2+, Mn2+ and in some months and those of Zn2+ 
in certain months far exceeded the safe levels found in Nile 
water. Despite that the Doneen parameter, that estimates 
water quality (Cl- + 0.5 SO42) should not exceed 5 in irriga-
tion water, both sewage effluent samples had values higher 
than the safe level. Special precautions and remediation 
biotechnologies should be considered to minimize health 
and environmental hazards for such waters.
