The experiment was conducted at Nile River (Rosetta branch) in Edfina, Beheira Governorate during three months
(December 2016, January and Febrauary 2017). The physical parameters such as (Temperature (T), pH, Electrical
Conductivity (EC) and total dissolve solid (TDS)) were measured in surface water. The results showed that temperature and
TDS were low significant within the permissible limits, but the pH was high significant (8.83) in February 2017. Also, chemical
parameters were evaluated and the Dissolved Oxygen (DO) was high significant in January 2017, Biological Oxygen Demand
(BOD), Chemical Oxygen Demand (COD) in December 2016. The concentration of ammonia ion (NH3-N), nitrite (NO2-N)
and nitrate (NO3-N) were fluctuation during the period of study. Some heavy metals were estimated in this study; cadmium,
iron, cooper, lead, manganese and zinc were less significant than the permissible limits. The results indicated that were within
the allowable limits according to Egyptian law number 48 of 1982. Microbiological tests were also carried out in the present
study measuring total coliform, total fecal coliform and number of algae, the results showed that the highly significant values
of the bacteriological counts such as total coliforms (130001.33 MPN/100ml), faecal coliforms (17002.33 MPN/100ml) in
February 2017, but the low significant values in the counts of total and fecal coliform and recoded 35003.33 in December 2016
and 1401.33 in January 2017, respectively. Also, the results obtained the algae were high significant (1621.33 N/ml) in January
2017 and low significant (406.33 N/ml) in December 2016. The results indicate that the river is highly polluted by various
chemical pollutants and pathogenic bacteria. Regular monitoring and immediate measures are required to reduce risks on
public health and the environment.
