Fresh groundwater, as an essential component of global water resources and a special type of mineral wealth, has a whole set of features that affect social infrastructure, the economy and the environmental well-being of the population. At the same time, groundwater is vulnerable and limited despite its replenishable nature and vast reserves. Recently, in some countries, the practice of extracting groundwater resources by private individuals on their territory has been actively spreading, but not in all states. This is considered acceptable and is enshrined in national regulations. Uncontrolled exploitation of aquifers by small water users can affect the safety of ecosystems and the depletion of drinking groundwater reserves. In this regard, the state policy and system for regulating access to groundwater resources for all subsoil users should be based on a well-thought-out concept. This article is devoted to the organizational, economic, and regulatory issues of groundwater extraction by individuals for their own needs in the Russian Federation. A comparative analysis of the state approach to groundwater extraction by private individuals in other states (mainly in the example of Germany and China) is made. The latest trends in legislation in this area are analyzed, shortcomings in the system of state regulation of groundwater use are identified, and mechanisms for legalizing the activities of individual water users are proposed. Global groundwater regulation should be based on rationality, control, safety, protection, sustainability, and future generations’ care.

In an era of rising population density and industrialization, the environment confronts growing challenges. Soil, agricultural land, and water bodies are becoming increasingly polluted by petroleum waste and hydrocarbons. While hydrocarbons are naturally present in crude oil, refining processes compound the complexity and toxicity of hydrocarbons. This is particularly evident in polycyclic aromatic hydrocarbons (PAHs) found in the air and soil, known for their carcinogenic, mutagenic, and teratogenic properties. In response, biodegradation emerges as an eco-friendly, cost-effective solution, especially in petroleum-contaminated settings. Biodiverse microbial communities play a pivotal role in managing hydrocarbon contamination, contingent on location, toxicity, and microbial activity. To optimize biodegradation, understanding its mechanisms is essential. This review delves into varied bioremediation techniques, degradation pathways, and the contributions of microbial activities to efficiently removing hydrocarbon pollutants. Recent research spotlights specific microorganisms like bacteria, microalgae, and fungi adept at hydrocarbon degradation, offering a contemporary perspective on petroleum hydrocarbon pollutant bioremediation. These microorganisms efficiently break down petroleum hydrocarbons, with enzymatic catalysis markedly accelerating pollutant breakdown compared to conventional methods. Given the intricate nature of hydrocarbon contamination, cooperative bacterial consortia are instrumental in effective cleanup, driven by specific genes guiding bacterial metabolism. For cost-effective and efficient removal from compromised environments, it is advisable to adopt an integrated approach that combines biostimulation and bioaugmentation.

The increasing population density and industrialization are adversely affecting the environment globally. The contamination of the soil, agricultural lands, and water bodies with petroleum wastes and other hydrocarbon pollutants has become a serious environmental concern as perceived by the impacts on the aquatic and marine ecosystem. Various investigations have provided novel insights into the significant roles of microbial activities in the cleanup of hydrocarbon contaminants. However, the burden of these pollutants is expected to increase many folds in the next decade. Therefore, it is necessary to investigate and develop low-cost technologies rapidly, focusing on eco-sustainable development. An understanding of the details of biodegradation mechanisms paves the way for enhancing the efficiency of bioremediation technology. The current article reviews the applicability of various bioremediation processes, biodegradation pathways, and treatments, and the role of microbial activities in achieving efficient eco-sustainable bioremediation of hydrocarbon pollutants. It is envisaged that an integrated bioremediation approach, including biostimulation and bioaugmentation is preferably advocated for the cost-effective removal of toxic petroleum hydrocarbons and their derivatives.
