The paper deal with learning actual problem on-farm land management that is estimating of the state of water bodies and the overall level of their technogenic load. It is noted that one of the most objective and reliable indicators required for such estimating is the content of heavy metals in the bottom sediments of a water body. We are systematized and described various methods for estimating pollution of bottom sediments with heavy metals, which based on the using the regional clarks of the content the elements in the soils and bottom sediments of background and conditionally background territories. Methods for calculating various criteria that reflect the degree of pollution the bottom sediments with heavy metals and conclusions about environmental risks based on such calculations are presented and analyzed.
