Nowdays the problem of fires is becoming more widespread and global in scale. According to statistics published by the Ukrainian Research Institute of Civil Protection obtained as a result of analysis of the fire registration cards of the SES of Ukraine – for 11 months of 2019 the number of fires in Ukraine increased by 23.1% compared to the same period last year. The most common extinguishing agent being used by fire and rescue units today is а foam. The main component of different foaming agents are surfactants. Their excessive emission into the environment leads to pollution of the surrounding areas. The constant increasing of the land areas affected by the effects of firefighting influence both the state of the environment in the region as a whole and the level of soil fertility. Microbiological indicators and the content of harmful substances in crops are increasing and thus the negative impact on public health grows. The analysis of microbiological monitoring methods with the aim of the contaminated solutions foam makers impact on the nearby territories’ soils estimation has been carried out. The pros and cons of modern physical and chemical methods of soils quality estimation have been defined. The necessity of microbiological methods usage which allow to get full and sufficient information not only about the pollution volume, but also to rate the results of such pollution has been justified. It is determined that in order to obtain the most complete and objective information about the microbiological condition of soils contaminated with foaming agents for fire extinguishing, a complex of bioindication methods should be used. It should include a growth test and a chromosome aberration test, with the use of test organisms that are most sensitive to the chemical composition of the test solution for firefighting.
