Tailings which are by-product of the extraction of various metals (copper, gold, silver, molybdenum, etc.) are often stored in so called Tailings Storage Facilities (TSF), where they are deposited as a soil-water mixture by spigotting. In many cases the water discharged together with tailings to the TSF is rich in salts and other chemical compounds imposing negative pressure to the groundwater environment. Even in the case of total or partial lining of such facilities and well-developed drainage systems to control leaching, some portion of contaminated water often seeps either through the surrounding dams or the bed into adjacent groundwater bodies. Numerical models can be very helpful tools to assess the extent of the contamination and particularly to predict its potential development in the future. This paper and the companion one describe such a numerical model developed for Żelazny Most Tailings Storage Facility (south-west Poland), one of the world’s largest tailings sites. In the first part general information about the facility is provided and a 3D hydrogeological numerical model of the structure is described. Groundwater flow pattern near the facility obtained from numerical simulations is confronted with the measurements from a comprehensively developed monitoring system. Part II will be focused on the modelling of chloride transport in groundwater.

The City

The soil over the bedrock in the city of Guangzhou is thin, with a depth of only about 11 m. Under such conditions, excessive exploitation of the underground space is very likely to affect the groundwater environment. In this paper, the impact of intensive underground structures, which act as barriers, on the groundwater flow in Guangzhou is investigated. The emphasis is on the impacts in terms of hydraulic head, Darcy velocity and groundwater balance. The study finds that: (1) Under the current underground structure density, the impact on the hydraulic head is small, and most of the change is in the range of ±0.5 m. (2) The Darcy velocity appears to be more susceptible to being affected by the structures. (3) The barrier effect of the intensive structures increases the overflow at the foot of the hills and reduces the transmissivity of the aquifer.

Static Water Level

The lack of reliable municipal water supply in the city of Port Harcourt has led to indiscriminate drilling of boreholes by the residents however, the direction of groundwater flow within the entire city has not been established. Hence, the research investigated the flow direction of groundwater in the study area in order to understand the best location for siting septic tanks and dumpsites with respect to the position of the existing or proposed borehole. This was achieved by determining the hydraulic heads (Hh) of twenty boreholes evenly distributed within the city by subtracting the static water level (SWL) from the corresponding earth surface elevation (E) with the use of a GPS and dipmeter. Results revealed that the hydraulic heads ranged from 0.14 – 23.16m while the surface elevation and static water level lies between 1.93 – 39.33m and 1.79 – 17.27m respectively. The contour map of the hydraulic heads indicated that the groundwater flows towards the southern and south-western directions hence, the residents were advised to take into cognizance when sitting dumpsites, landfills, and septic tanks with respect to proposed or existing boreholes.
