Geochemical and petrographic assessment of clay outcrops and archaeological ceramics from the pre-hispanic site of Aguas Buenas (cal 400–1250 CE), Central Nicaragua

This research characterizes and reconstructs clay procurement and production practices through the integration of in-situ portable XRF and petrographic analysis on ancient ceramics and clay materials recovered from the Mayales river subbasin (central Nicaragua). A particular choice for this study was the largest and arguably most significant...

As(V) rejection by NF membranes using high temperature sources for drinking water production

In Nicaragua, a Central American country, geothermally influenced waters are frequently found to be contaminated with arsenic (as As(V)). This study investigated the effect of high-temperatures (25–50 °C), as found in geothermally influenced source waters, on the rejection of monovalent H2AsO4 - and divalent HAsO4 2- species (at pH 6,7 and 8)...

Arsenic contamination of rural community wells in Nicaragua: A review of two decades of experience

Several surveys have been conducted in Nicaragua between 1996 and 2015 confirming the presence of high levels of arsenic (>10 μg/L). In this paper, these peer-reviewed (n = 2) and non-peer reviewed sources (n = 14) have been combined to provide an extensive overview of the arsenic contamination of drinking water sources in Nicaragua. So...

Arsenic removal from geothermal influenced groundwater with low pressure NF pilot plant for drinking water production in Nicaraguan rural communities

This research evaluated the effect of different fluxes (16, 23 & 30 L/m ² h) and temperatures (31,35 & 43 °C) on the rejection of As(V) during nanofiltration (NF) of natural geothermal influenced groundwater in Nicaragua. A NF pilot plant powered by solar panels was built and operated in rural community Telica, exposed to...

The Arsenic Project: A multidisciplinary Project in Nicaragua

In Nicaragua, active research for arsenic started in 1996, after the first case of arsenic poisoning was reported in a rural community. Arsenic concentrations present in drinking water cause chronic poisoning, which depending on the exposure, lead to several life-threatening long term effects. It is however unknown to what extent this...

Nicaragua Canal Project Description

The Canal de Nicaragua (Project) is a major infrastructure project with the potential to transform global trade and make Nicaragua a major center for transport and global logistics. The Project would be one of the largest civil works projects ever undertaken. This Project Description is being released by HKND to inform the Government of...

Rebinding the centre: An urban restructure proposal of the Historical City Core of Managua through its cultural, landscape & heritage assets

The process of the phenomena of urbanization within developing countries in Latin America, such as Nicaragua, has increased the appearance of urban informality in the socio-spatial structure. Moreover, the lack of a clear planning framework has led Nicaraguan cities such as Managua, to an urban structure, which is no longer related to its...

Anaerobic Treatment of Coffee Wastewater: A study on monitoring and implementation of biogas at Finca el Socorro, Matagalpa, Nicaragua

In order to achieve the Millennium development goals of the UN, different initiatives have been established worldwide. One of these initiatives has been developed in Matagalpa, Nicaragua. Through the program Agua para Todos – Agua para Siempre different institutions work together, the common goal being to provide safe drinking water and...
