The consequences of contaminated groundwater can seriously affect sustainable development; present and future generations being seriously affected by inadequate drinking water quality, loss of water supply, degraded surface water systems, high remediation costs, more expenses for other water supplies, and likely health issues. Therefore, an effective way to protect groundwater resources is by assessing the risk of groundwater contamination. An assessment of groundwater pollution should be performed to determine the level of risk posed by soil and groundwater contamination and establish if remediation strategies are required to protect controlled waters from site-derived contamination. Furthermore, if remediation is deemed necessary, site-specific remedial targets should be derived. A case study is presented, where a Conceptual Site Model was derived based on a “Source-Pathway-Receptor” exposure mechanism using historical information. Primary sources of contamination at the site are residual contamination within the soil and groundwater, and samples were collected from the site and tested in the laboratory; the concentration of water samples was compared to Romanian Drinking Water Standards. The following potential migration pathways have been identified: Leaching from soil and Migration of contaminated groundwater. The Detailed Quantitative Risk Assessment (DQRA) has modelled the leaching of contaminants from the site via infiltration and vertical migration to the groundwater and subsequent lateral groundwater migration, with dilution and attenuation process active, to the compliance point, using Ogata-Banks equation. The results of this assessment indicate that the concentration of contaminants does not represent a significant risk to controlled waters.

Stone blocks, such as marble, granite, and sandstone, are natural materials with excellent properties. The most important dimension stone in Romania is Ruschita marble, a natural stone known for its resistance to wear and ability to maintain its natural beauty, regardless of its colour. Regarding colour palette, Ruschita marble stands out for its excellent quality to suit even the most demanding requirements. It is available in shades such as yellowish, orange, pale pink or pink, with a compact structure and characteristic veining. Ruschita is Romania’s most famous marble deposit, exploited since the end of the 19th century. The quarry exploitation is conditioned by naturally occurring fractures and discontinuities, such as faults, joints, and fissures, precluding larger blocks excavating with more significant commercial value. This paper describes two largely used techniques for discontinuity investigation, namely the televiewer and scanline methods used at the Ruschita marble quarry.
