Groundwater usually contains quite large amounts of iron (Fe). The Fe content in water causes health problems and can also cause a metallic taste or smell in drinking water and a yellow color on the walls of the tub and clothes. Iron content: high levels of water consumed will affect the health of the human body, namely damage to the liver, kidneys, and nerves. The presence of iron in water must comply with the quality standard values set by the government, namely 0.3 mg/l for drinking water and 1 mg/l for clean water. By combining various filtering media, such as zeolite and ferrolite, with oxidation reactions using aeration techniques, it is possible to reduce the amount of iron in water. This research aims to determine the effect of bubble aeration and various filtration media on the levels of Fe in excavations. Materials and Methods: The first treatment is for control, then the second treatment is carried out, namely using variations of bubble aeration and then combined with filtration media such as zeolite, ferrolite, and a combination of both. Data analysis was carried out using the one-way ANOVA statistical test. Results: The study's findings showed that Fe levels dropped by 16.61% when there was no aeration or when there was aeration at 5, 10, 15, 20, and 30 L/min. They dropped by 31.63% and 45.05% when there was aeration at those rates. %, 51.99%. 55.40% and 67.69%. Variations in bubble aeration discharge can significantly influence Fe levels in dug well water, with a significant value of 0.000. Conclusion: The use of aeration techniques to reduce Fe levels in dug well water can be done, but it should be combined with other water treatment techniques such as sedimentation and filtration.
