Water quality assessment with aquatic non-structural blocks made of coal ash aggregates mortars
A handful of biochemical processes occur in aquatic environments. One of the problems that are mostly encountered in such environments is caused by excess nutrient input and subsequent algal bloom. A series of studies were ...
Disinfection by-products occurrence and Escherichia Coliform removal in a point-of-entry cistern purification unit
This research aims to develop and test a Point-of-Entry Cistern Purification Unit (POE-CPU) to guarantee water quality for household purposes, with an emphasis on turbidity, E. coli removal and minimal occurrence of ...
Historical assessment of chlorinated volatile organic compounds (CVOCs) and phthalates contamination in the northern karst aquifer of Puerto Rico using GIS
Contamination in Puerto Rico (PR) is extensive with more than 150 contaminated sites and a vast contamination of water resources. Among the most impacted areas is the northern coast karst aquifer. This project (1) evaluates ...
Development of ternary relationships among soil characteristics, CAAs amount, and groundwater quality: column percolation
Coal ash aggregates (CAAs) from a coal power plant was evaluated for use as a backfilling substitute in open pit restoration. The restoration was successfully simulated under laboratory conditions by using three dissimilar ...
