This study was conducted on nine wells water within Kirkuk city for the period 1st July 2015 until 13th June 2016 to assess the electromagnetic field's effectiveness in groundwater purification, where the study focused on the design apparatus with different electromagnetic fields accomplished by exposing the water to electromagnetic fields while the water is passing through the device. Electromagnetic water treatment process consists of two phases , the first by using different electromagnetic fields 1.4,1.7,1.9 Tesla with the stability of the water passage time 20 minutes through electromagnetic field and the second phase is consists of fixed electromagnetic field intensity 1.9 Tesla with change water retention time 5, 10, 20 minutes during the electromagnetic field. Study showed the effect of electromagnetic treatment on bacterial pollution indicators (total number of aerobic bacteria and total coliform bacteria) the number of bacteria colonies decreased at a rate of 90% at a field intensity 1.9 Tesla and to 93% at a retention time 20 minutes, as the coliform bacteria decreased at a rate of 94% when field intensity 1.9 Tesla ,and [98thvd retention time 20 minutes

Study showed the effect of electromagnetic treatment on wells water hardness. The total hardness decreases at a rate of 18% when the field intensity 1.4 Tesla and 31% when the field intensity1.7Tesla , while the total hardness value decrease at a rate of 48% when the field intensity 1.9. The total hardness decreased at a rate of 15% when retention time 5 minutes and to 30% when retention time 10 minutes , while the total hardness decreased at a rate of 57% when retention time 20 minutes
This study has been conducted form July 2012 to June 2013 to realize the influence of sewage treatment by sedimentation and filtration and use for irrigation of Celery plant Apium graveolens L.Physical and chemical tests has been conducted for irrigation water before cultivation, soil testes included pH , Electrical conductivity, soil texture, cation Exchange Capacity, Organic matter and the concentration of ions and heavy metals,water tests included pH , Electrical conductivity, temperature, Biological Oxygen demand, Total dissolved solids,Total suspended soils and concentration of ions included heavy metals. Results indicated that treatment by sedimentation and by filtration redused most Physical and chemical values of sewage water as compared with untreared water (control),and the concentration of cadmium and lead in four samples of water in the current study were very low, and not sensed by atomic absorption spectrometer. Zinc ion concentration was not affected significantly in treated water as compared with untreated water (control), and the concentration of lead in parts of the plant was very low, and not sensed in the test, there were no significant changes in cadmium and zinc concentrations in celery roots irrigated with water treated by sedimentation and filtration, while zinc concentrations decreased in celery shoots. Irrigated with water treated by filtration by 58.62%, and the consumption of these crops will cause health problems for community in the future.
