The present study has been conducted to investigate the effect of organic substance of klkoz and the clover added to the soil on the decomposition of dayizon pesticide in the soil , and the effect of this on the microbial activity of microorganisms in addition of the organic Carbon ,Nitrogen and Phosphorus in the soil –A type of mixed soil was used in the study – It was brought from an agricultural field in the city of Ramadi in which no type of pesticides had been used for a period of more than ten years . The organic substance of klkoz and the dry clover remaining had been added and cultivated well in the soil at a ratio of %1 for all treatments. Three concentrations(0, 250,500) ML.100L. Donam had been added to the soil according to the treatment. All these treatment had been incubated at a tempreture%28 for(20,40,60)days. Then, the total number of microbe, fungi, Actinomycetes ,Bacteria solvent for phosphate ,cellulose decomposing Bacteria, Aozossberellim Bacteria , and the Azutobkatr Bacteria were estimated in the soil .Besides, the Nitrogen, the organic carbon, and phosphor , were also estimated in the soil under study .The results revealed that the addition of the organic substance has a great role in the increase of different races of microorganism in the soil and in the decrease in the inhibitory effect of pesticide under study . It was indicated that there was a differentiated effect of adding an organic substance to the soil at %1. This led to an increase in the total numbers of the treatment that used a pesticide . The numbers reached the higher level after a period of incubation of (60) days on the other hand , when the pesticide used without an organic substance , the effect was higher that the total numbers of microbe decreased differently according to the difference in the concentration used and the period of incubation , so that difference between the treatment of comparison and au treatments of the pesticide was significant from the period of incubation (20) days until the end of the experiment (60) days . This recorded the less effect of the recommended dose of the used pesticide on the other hand the effect was inhibitory , signification and clean when using a double dose of pesticide recommended in the field. The decrease in the numbers as a result of using the pesticide with the existence of the or organic substance was little ,and this indicates that using the organic substance kolkhoz and clover led to a decrease in the effect inhibited to the pesticiot on the total number of microbe especially used in the case of uling a double close of pesticide used in the study . At the end of the experiment ,it was showed that the inhibitory effect, during a period of incubation and to days, was clearly least at using the organic substance with the three concentrations of pesticide. The result, also rescaled that the Nitrogen .and phosphorus in the soil reached the higest value after a period and (60)days and incubation in the treatment in the which the organic substance was used without wing the pesticide. But when the pesticide was used without the existence y the organic substance, the effect on the Nitrogen and phosphor was higher. The fixed effect was little especially at using the organic substance on the pesticide with all its three concentrations. whilst ,it is found that the organic carbon in the soil decreased gradually with the increase of the in cubation .Period. This is due to activity of the microbe in the soil

Our study was aimed to assess seasonal variation of Main Outfall Drain and: Al-Es'haky, Sabe'e Al-Bor, Al-Saglawia and Al-Shuala trocars using several physical and chemical variables, water samples were collected from the surface about 10-15 cm in depth from these sites from February 2010 to January 2011. The results show that the mean of temperature was significantly (P ≥ 0.05) affected by seasonal temperature and seemed to be lowered during winter (13.26 ± 2.6 to 14.3 ± 1.9) and was high in summer ( 22.6 ± 2.6 to 23.9 ± 1.2 ) but un affected (P≤0.05) by water collecting sites. For pH values, the obtained results seem to be almost not acidic and also not significantly influenced by either the climate seasons or by collection sites and found to range from 7.8 ± 0.2 to 8.8 ± 0.3. However, similar findings were recorded for electric conductivity where again insignificant impacts (P ≥ 0.05) of both climate seasons and collecting sites and mean values varied from 188.0 ± 0.0 to 2380.3 ± 10.0 µS/cm. Mean dissolved salt content was found to be significantly affected (P ≥ 0.05) by collecting sites but not by climate season and highest value (1260.0 ± 14.2 mg/l) was recorded in Al-Es'haky samples while the lowest value (1670.3 ± 30.0 mg/l) was in the Main Outfall Drain samples. However, the mean dissolved oxygen content was in general high in winter, spring and autumn and relatively lower in summer and such data were insignificantly differed (P ≤ 0.05) from each other in case of climate season but were very significant (P ≥ 0.05) in case of collecting sites. Al-Shuala samples had the lowest values (6.0 ± 0.4 to 8.0 ±0.2 mg/l) while Main Outfall Drain sample showed highest (8.4 ± 0.0 to 9.0 ± 0.1 mg/l) values. For oxygen saturated percentage, it was found that the mean value was not significantly (P ≤ 0.05) affected by both clime season and collecting sites except for Al-Shuala samples which was significantly (P ≥ 0.05) different. Similar findings were found for BOD mean values where the recorded data were again insignificantly (P ≤ 0.05) influenced by both climate season and collecting sites except Sbe'e Al-Bor trocar which had the significantly (P ≥ 0.05) lowest values ranging from 1.3 ± 0.3 mg/l in winter to 2.6 ± 0.3 mg/l in summer.

Turbidity is one of the of drinking water treatment problems. Turbid water contains molecules, plankton and colloids, is dealt with through the addition of coagulation chemicals in a process called coagulation and flocculation. In this research, three of the most commonly used coagulants used in water treatment process were examined for their efficiency in reducing turbidity. Those are Aluminum sulfate (alum), Ferric chloride and Poly aluminum chloride (PACl). Experiments were conducted using synthetically prepared turbid water by adding kaolin and using a Jar test instrument to define the optimum dosage from each chemical. The tests were conducted for two turbidity levels; 52 and 580 NTU. The results showed that Poly aluminum chloride is more efficient than both alum and ferric chloride. A dosage of 75 mg/l from PACl reduces the turbidity of the water from 580 to 4.55 NTU (99.2%), and from 52 to 1.5 NTU (97.1%). Applying the same operating conditions, Alum and FeCl3 should be a lower efficiency for turbidity removal. The efficiency of Alum and Ferric were 98.5% and 93.8% for water with 580 NTU, and 98.8% and 86.1% for water with 52 NTU.
