Prof. Ahmed Abdullah Ramadan, a lecturer in the Department of Petroleum Technology, published a research entitled "The chemical and theoretical content of rainwater and the preparation of the rain line in the city of Baghdad".

The objective of the research is to determine the properties of chemical, physical, and isotopic rain water and to prepare the rain line for the city of Baghdad.

The researcher found that the values ​​of pH (5.5-6.44) ranged from mild acidity to neutral and, the total soluble salts from (84-189) ppm , the negative and positive ions / values ​​of sodium ions (11.59-28) mg / L , potassium ions (0.05- 1.05) Mg / L , magnesium ion (2.2-9.7) mg / L , calcium ion (11.22-36.2) mg / L , chloride ion (17.5-39.82) mg / L and bicarbonate (18.3-49.57) mg / L and sulfuric acid (12.47-38.34) Mg / L as well as the determination of the isotopic content of (9) rainwater samples including deuterium and oxygen-18, with values ​​of deuterium (-7.25-0.79%) and oxygen -18 (-48.78-18.75%).
