In order to further study the problems of urban engineering geological environment, taking Jinan as an example, the environmental engineering geological problems are divided into four aspects: primary environmental engineering geological problems, secondary environmental engineering geological problems, the influence of human activities and the restriction of spring water on engineering construction. A multi-level, multi-objective and multi factor evaluation index system suitable for environmental engineering geology is established. The mathematical model is established by using analytic hierarchy process and fuzzy comprehensive evaluation method to evaluate the primary environmental engineering geological problems, secondary environmental engineering geological problems, the impact of human activities and the restrictive effect of spring water on engineering construction. The mathematical model is established by using Nemero index method to comprehensively evaluate the environmental engineering geological problems in Jinan, and the suitability zoning of engineering construction is carried out.

Resumo: A área de estudo está inserida na Bacia do Rio Pirangi, RN, ocupando superfície de 370 km², onde situase a cidade de Parnamirim. A expansão urbana no município de Parnamirim dá-se de forma acelerada e sem uma estrutura adequada, notadamente pela ausência de rede esgotos, com riscos de contaminação das águas subterrâ-neas, que constituem a principal fonte de suprimento hídrico das demandas urbanas e rurais. O presente estudo foi elaborado com o objetivo de quantificar o uso e avaliar as potencialidades das águas subterrâneas, considerandose a necessidade do aumento da oferta de água de boa qualidade e menores riscos de serem afetadas por atividades antrópicas. Foi realizado um cadastro atualizado de poços e a caracterização do arcabouço hidrogeológico, seguido da avaliação dos parâmetros hidráulicos do aquífero e do comportamento do fluxo subterrâneo. A espessura saturada do Sistema Aquífero Barreiras aumenta de oeste para leste, variando de 15,47 a 56,5 m (com média de 32,45 m). Os parâmetros hidrodinâmicos foram estimados a partir da interpretação de ensaios de bombeamento, que forneceu transmissividade média de 5,9x10-3 m²/s, condutividade hidráulica média de 2,82x10 -4 m/s e porosidade efetiva média de 15%. O sentido do fluxo subterrâneo é em geral de oeste para leste, sendo possível identificar as correspondentes zonas de recarga e de descarga das águas subterrâneas. A Recarga foi estimada em 253 mm/ano, que corresponde à uma taxa de infiltração de 16,4% da precipitação.Palavras-chave: Sistema Aquífero Barreiras. Desenvolvimento urbano. Potencialidades Hidrogeológicas. Abstract:The study area is within the Pirangi River Basin, situated in the state of Rio Grande do Norte, Brazil, covering about 370 km², where is located Parnamirim city. Urban expansion in the municipality of Parnamirim occurs under accelerated rates, and it takes place under no proper infra structure, notably by the lack of sewage networks, presenting high risks for groundwater contamination. Groundwater consists on the main source of water to supply urban and rural demands. The main purposes of this study were to quantify the use and evaluate the potential of groundwater in the area, considering the requirements of good quality water supply preventing the possibility of risks against human activities. During this study an updated register of wells and a characterization of the hydrogeological framework of the area were carried out, followed by the assessment of hydraulic parameters of the aquifer and the groundwater flow behavior. The saturated thickness of the Barreiras Aquifer System increases from West to East, presenting values ranging from 15.47 to 56.5 m (average of 32.45 m). The hydrodynamic parameters were estimated based on the interpretation of pumping tests, which provided transmissivity average 5.9x10 -3 m²/s, hydraulic conductivity average is 2.82x10 -4 m/s and specific porosity average of 15%. Groundwater flow direction is generally from West to East, allowing the recognition of recharge and discharge areas. Recharge w...

This study aims to assess the extent of hydrocarbon and heavy metal contamination in soils from specific areas on Azerbaijan's Absheron Peninsula, including Absheron, Suraxanı, and Baku, and to evaluate the impact of this contamination on soil properties. Soil samples were analyzed for Total Petroleum Hydrocarbons (TPH) and heavy metals, including aluminum, arsenic, cadmium, lead, and iron, alongside assessments of soil physical, chemical and biological properties. The results revealed significant contamination across all studied areas, particularly in Suraxanı, where TPH levels reached 190 ± 20 mg/kg, exceeding the environmental standard of 100 mg/kg. Similarly, Suraxanı soils exhibited alarmingly high concentrations of heavy metals, with aluminum at 30,128 ± 1,500 mg/kg, arsenic at 50.94 ± 2.5 mg/kg, and cadmium at 0.153 ± 0.01 mg/kg, all surpassing acceptable limits. These contaminants severely degraded soil health, evidenced by increased bulk density (1.7 g/cm³ in Suraxanı) and reduced soil porosity. Microbial activity, a key indicator of soil fertility, was also markedly lower in contaminated regions, with the total bacterial count in Suraxanı being less than half that of the uncontaminated area. The findings underscore the urgent need for comprehensive soil management practices and stricter environmental regulations to mitigate contamination's adverse effects and protect both ecosystems and public health in Azerbaijan’s petroleum contaminated areas.
