Septic systems that are built in compliance with regulations are generally not expected to be the cause of groundwater borne disease outbreaks, especially in areas with thick vadose zones. However, this case study demonstrates that a disease outbreak can occur in such a setting and outlines the combination of epidemiological, microbiological, and hydrogeological methods used to confirm the sour...
18 Groundwater contamination was characterised using a methodology which combines 19 shallow groundwater geochemistry data from 17 piezometers over a 2 yr period in a 20 statistical framework and hydrogeological techniques. Nitrate-N (NO3-N) 21 contaminant mass flux was calculated across three control planes (rows of 22 piezometers) in six isolated plots. Results showed natural attenuation occu...
Quasi three-dimensional (quasi-3D)modelling plays a major role in analysis of groundwater flow in multiaquifer systems and it can be an efficient tool for artificial recharge modelling. As the role of artificial recharge in groundwater management continues to increase, analysis of responses to artificial recharge has a particular significance. This paper deals with some practical aspects of the...
In 2010–2012, the hydrogeological model (HM) of Latvia LAMO was established by scientists of Riga Technical University (RTU). The commercial program Groundwater Vistas (GV) is used for running LAMO. Efficient methods have been used for creating geometry of HM, the arrangement of various boundary conditions (digital terrain map, hydrographical network, infiltration flow, conditions on the HM she...
