We used Bacteriological studies to determine the quality of water, through quick methods, simple and sensitive detection of water contaminants, and in particularly bacteria that indicated the health status of water quality. We presented in this study
the effect of sewage on distribution nutrients and the Streptococci bacteria. Seven samples were taken during the period 2013 to 2014, at a rate of two cruises per season. Some of these samples were taken in near sewage stations, others, to make a comparison, were taken in distant ones. The study showed an increase in nutrients. These bacteria were linked to a positive relationship with nutrients because the presence of nutrients stimulated bacterial growth.
The big value of dams in the Syrian coast comes from using them for irrigation and sometimes as source of potable water. This study aimed to determine some chemical indicators of water quality in Lattakia dams during ten years (2002-2011). The
conce
ntrations of ions (Cl-1, SO4-2, NO2-1, NO3-1, PO4-3, K+1, Na+1) in five dams (Balloran, 16 Tishreen, Al-thawra, Alsafarkia and Alhweez) were studied. The results indicated that most of the ions showed significant difference in concentrations during 2002-2011.The ions concentrations in most studied dams increased. The increase related to characteristics of dams (location, capacity, the activities located around the dam…).
Water quality in Mzereb lake was assessed during 2010-2011 by measuring
number of physical, chemical and microbiological parameters which are
important in determination water quality.
This research aims to study dynamics cyanobacteria population in the
Room reservoir (in the south Syria: Sweeda), which affected by water quality
environmental conditions, and seasonal. 17 genera where identified and their
dynamics studied monthly
during 2007, calculate the biomass of the prevail
genera. The bloom was occurred in October, and the value of diversity
coefficient was the highest in July in the Room reservoir, but didn't occurred in
the Jouelen reservoir.
This research aims to evaluate the water quality of the Al-Sain lake which feeds
mainly the Lattakia city and a part of the Tartous city of drinking water purpose.
In this paper, we study a group of physical and chemical factors for the water of th
e
Al-Sain lake during the years of available data (1991-2004-2007-2011), samples were
taken from four different locations according to the program approved by the concerned
staff to monitor and protect the lake, namely: (Lattakia water supply point, Tartous water
supply point, irrigation point, southern spring observatory), and we calculated the quality
index for drinking purposes using US approved methodology of National Sanitation
Foundation. Nine factors have been adopted: (dissolved oxygen, fecal coliforms, pH,
BOD5, temperature, phosphate, nitrates, turbidity, and total solids).
The research result showed that the classification of water quality was good in all
four monitoring points during the years 1991 and 2004, noting a significant improvement
of the quality in 2004, and decreases slightly during the years 2007 and 2011 for
monitoring points in the Lattakia water supply and irrigation points, but water quality still
keep maintain a good classification, while the quality of the water goes down within the
threshold of middle classification for the Tartous and southern spring observatory
monitoring point.
This research discusses the problem of drinking water shortage and
distribution instability in Salamyeh city due to the current crisis.
Salamyeh city dependents on Orontes River as a source for drinking
water through Hama water supply facility, wh
ich sufferes repeated
sabbotage attacks. As a result, an emergency measure was implemented
by depending on local water sources within the city, which are deep wells
that produce water of sulphuric nature.Three desalination plants were
provided to treat local sulphuric water producing suitable safe water, but
these plants production is way less than the city needs.
Al-Sourani Dam was built to provide drinking water for inhabited villages in Sheikh
Badr –Tartous, but the lake water is exposed to pollutants from several sources. In this
paper, we discuss the mechanism of pollution and the appropriate measures,
by
determining some physical, chemical and biological characteristics of water in different
sites.
The results showed that turbidity and pH values arise in the autumn and winter
especially in the water of tributaries compared with the water of the lake, this may be due
to the activated runoff following rainfall in this period. Whereas the ammonium ion
showed a significant increase in the lake's tail, that can be attributed to sewage residues
from Broummana Al-Mashaeikh that threw directly into the lake. The results also showed
remarkable seasonal changes concerning the total microorganisms in all studied sites,
where the highest value was recorded in winter that reached 5.36 × 104 cells / 100 ml in
Aine Alzaaror tributary.
we conclude that the main source of pollution of lake's water, was the polluted water
coming from Broummana Al-Mashaeikh, in addition to Aine Alzaaror tributary, that flows
near a restaurant. The second source is Al-Wade Alakhdar tributary that feeds permanently
the lake. So, the lake's water should be sterilized before using for drinking.
An experiment was conducted for two seasons 2015 -2016, to study the effect
of treated waste water (TWW) on some fodder crops productivity at Salamieh
Research Center (GCSAR), on triticale and sesbania crops within crop rotation. This
experiment w
as conducted with collaboration between (ACSAD) and (GCSAR).
The experimental design was split plot design with three replicates, using drip
irrigation (DI) and surface irrigation (SI) systems with two treatments namely fresh
water (FW) and (TWW). Soil and water were analyzed before cultivation.
