Abstract. The history of mining activity, which has been the economy engine in the region and has contributed to the formation of many localities, has been deleted too quickly. During all this time, in the world countries which have invested in mining sector have made considerable progress. The paper brings in question, within the framework of the theme, the implications arising from the abandonment of the Romaltyn project which mainly affects two objectives: Central Tailing Pond and Aurul Tailing Pond. The Central tailing pond constitutes an unfortunate source of pollution for groundwater, surface water, soil and air on a large area around it, because its location upstream of Baia Mare city and in the vicinity of a agricultural production zone. The consequences of the tailing pond maintenance in the current situation are: presence of sclerozing dust with sulphurs content scattered over large agricultural area; soil pollution by acidification; heavy metals release which enter in food chain and will be found in food. The final disposal of the pollution source is the only solution really safe in long term. Abandoning Aurul tailing pond in the current phase of construction involves high environmental risks. Taking in consideration the potential and the huge soil volume which are necessary for rehabilitation, isolation and rehabilitation of this area involve extremely high costs and the realization is, technically, almost impossible in the current context.

The paper presents the context in which the closure of the mining in the Maramureş county took place by carrying out some inappropriate works that generated phenomena with a strong environmental impact through manifestations, physical and chemical in nature. The analysis performed so far shows that these events will amplify the environmental impact on the public health in the future, with long-term consequences.

The topic presented in the paper refers to two significant aspects regarding the impact of mining operations on the environment and the development of an alluvial mining project in the affected area. The mine waters that drain from the Cizma mining perimeter have an acidic character with a pH of 2.5 at the exit of the gallery with a load of heavy metals in ionic and precipitated form, discharging into a mountain stream, which later reaches in the area of some communities. The perimeter is located in a protected area, which encumbers exploitation projects in these areas.

Waste management in Romania has become a problem with a very high environmental impact, especially in Maramureş County where it has overlapped with the pollution of mining waste. The article highlights the current context in which the population does not accept the construction of landfills, the authorities are not able to provide proof of competence, reaching a vicious cycle in which everyone loses. In this context, we consider that the substratum of the problem is the ignorance that manifests itself in the form of hypocrisy, most of those involved are "ecological", but in reality the environmental impact of irresponsible waste management is very serious.
