In this paper, the corrosive properties of the water treatment plants system and biological stability were clarified. Several studies and dissertations published in this subject were reviewed in this paper. The problem of corrosion was explained and the reasons for their occurrence, Methods are used to reduce this characteristic, water stability and the factors affecting corrosion, Stability and correlations, which included five indicators: Langelier Saturation Index (LSI) ,Ryznar Stability Index (RSI), Puckorius Scaling Index (PI, Larson–Skold Index (LS), Aggressive Index (AI).

Precipitation is an important but highly variable atmospheric parameter. Existing rain gauge networks cannot provide the temporal and spatial coverage that is needed to monitor it sufficiently. Satellite measurements have the advantage of providing spatially homogenous observations over large areas. The aim of this research is to estimate rainfall over Iraq using satellite data. Hourly and daily observations of rainfall measured by ground stations, for several locations in Iraq, were compared with estimations of rainfall obtained from Meteosat 9 and Climate Prediction Center (CPC) Images.Results of these comparisons indicated that the hourly values of rainfall measured by ground station at Baghdad were very close to the estimates obtained by satellite. The comparisons of daily rainfall values, for Baghdad, Basra, Mosul, and Rutba,with the estimated values of rainfall obtained from CPS showed that 73% of the case studies for the period of 2001 to 2008 were in a good agreement. These results suggest that rainfall estimates from satellite date can be very useful for many applications such as agriculture and water resources.

Phenol [C6H5OH] is a sweet-smelling compound generally present in effluents of numerous businesses. Phenol is far reaching toxin in the earth, amazingly perilous and determined in water speaking to genuine environmental issue and general wellbeing hazard. The destiny and conduct of phenol in nature is about the worry for the ecological toxicology and general wellbeing checking. Different microorganisms are engaged with the vigorous biodegradation process other than natural parameters that influence phenol debasement. Supplement prerequisite, bioavailability of phenol and other natural variables assume a significant job in understanding the procedure of phenol debasement. Be that as it may, the current the phenol in condition parts has been the real natural toxin present among the wide assortment of poisonous natural synthetic concoctions and biodegradation is an alternative that give the likelihood to crush different innocuous contaminant of phenol utilizing common organic activity.

In this study, an electro-kinetic method applied for the purpose of eliminating lead from contaminated soil (sandy), and this technology is applicable in low permeable soils. Many sets of experiments conducted with different enhancedconditions, including different electrode purging solutions, voltage gradient. Bitter orange peels (BOP) was used as a low cost adsorbent material to prevent reverse osmosis flow, which may affect the removal efficiency. The results showed that the removal efficiency increase with decrease in pH of the purging solutions, three tests were conducted using purging solution at pH 4.5, 6 and 7.5 respectively, the best removal efficiency was 85.16%at pH=4 comparison with other two tests at pH 6 and 7.5, where the removal efficiencies were 80.32% and 72.4%, respectively. The experiments proved that the pb removal from the soil increased when voltage gradient increased, where the removal efficiency at 1.5 V/cm was 85.16% comparison with the test at 1 V/cm, where the removal efficiency was 82.1%. This study proved that the (BOP) is a good adsorbent material to prevent the reverse electro-osmotic flow, and hence it could be considered economically and beneficially as a good adsorbent medium.

The levels of natural radioactivity and noise at a number of locations in industrial area of Hillah city have been measured. The measurements were done by using tow devices: Alert (Inspector 33290), Noise meter (NM 104), for several days (December of 2017), during day-time from 9 am.-12 am. With respect to measure the radioactivity, there are three repetitions per location test were taken. Moreover the distance between the device and measured material was (30 cm). The results show that all the values of natural radioactivity are within the permissible limits, where the highest averages for radioactivity rats is (0.0095 μSv/hr) registered at the house of worship, likewise the lowest value is (0.005μSv/hr) recorded near of Al Wa’illy school. On the other hand the averages of noise levels at entire locations are significantly elevated, where the highest values recorded at the interior of industrial area (2.7 dB), and the lowest averages at the interior of industrial area (64.9 dB) was registered at the Bazar area.
