At present owing to increase of anthropogenic impacts on the environment in Kaluga region the problem of surface and groundwater pollution has been attached more importance to. Objects of research are underground springs. Anthropogenic activity of person is the main reason of their pollution. People founding settlements, industrial enterprises, agricultural facilities, laying pipeline, building roads, dumping and etc. in zone of springs feeding degrade water quality of rivers and lakes having usually have close hydraulic connection with underground waters, and cause emer-gence and development of steady pollution in underground water-bearing systems. The carried out analyses of spring water pollution reveal that the qualitative composition has considerably worsened for 10 years past. One of effective physical and chemical methods of natural waters purification from microbial pollution is the method of water treatment with coherent radiation. The new method of laser influence will help to optimize water treatment system and also to increase products quality.
