TL;DR: A two-stage system for treating high-strength wastewater from an abattoir at Pachuca, Mexico is described in this paper, which consists of an anaerobic digester followed by an artificially-constructed wetland which employs horizontal subsurface flow through the root zone of emergent hydrophytes planted in a gravel substrate.

TL;DR: In this paper, the environmental effects of wastewater irrigation on the subsurface at two locations in Mexico; Leon and the Mezquital Valley were analyzed for a range of physico-chemical and microbiological parameters using standard methods.

TL;DR: A survey of pathogenic and free-living amoebae in swimming pool waters of Mexico City was performed and it was shown that the free residual chloride values of 0.50 to 1.5 mg/liter, ordinarily used in pool waters, are not adequate for elimination of amoEBae.

TL;DR: The constant presence and diversity of free-living amoebae in the treatment system were important findings due to the characteristics of the wastewater from the textile plant in terms of the residue content from colorants, fixers, carriers, surfactants, etc., used in fabric dyeing and finishing processes.

TL;DR: In this article, the authors characterize the presence of pathogenic free-living amoebae and bacterial indicators (total and fecal coliforms), and ascertain the removal efficiencies of physical and chemical pollutants, in a constructed wetland treating domestic wastewater from a single household.
