This resource inventory, encompassing the economically viable area within the Turrialba Diversification Project (which includes the canton of that name and a portion of the adjoining District of Tucurrique), was carried out during July-September, 1968, by five students of the Resources for Development Unit of the Training and Research Center of the Inter-American Institute of Agricultural Sciences, under the guidance of faculty and associated members of that Unit. Its objectives wer to obtain a systematic knowledge of the physical and human resources of the study area and to assess, in preliminary fashion, the possibilities for expanding and systematizing the existing diversification program of the municipality. The scope of the inventory was restricted, firsts of all, to the time and personnel available and, secondly, by the fact that the terms of reference included only agriculture and silvicuture rather than a complete range of employment and land use alternatives for diversification (industri, touris, etc.). Maps were fist compiled on the physical characteristics of the area in question: geomorphology, slope, soils, ecology, and various aspects of climate. Partially summarized in a land capability map, these factors were then used to delimit areas which seemed most suitable for certain crops, selected from a much more extensive list, that were deemed to be particularly promising given the physical conditions of the study area. |

The reuse or recycling of wastewater provides environmental and economic benefits, representing a sustainable and circular alternative for the management of liquid waste. However, the application of effluents to agricultural crops via spraying creates a potentially dangerous situation for individuals exposed to airborne pathogens. This study used Quantitative Microbial Risk Assessment (QMRA) tools to quantitatively assess the microbial risks of occupational and public exposures to bioaerosols in fertigation scenarios by spraying untreated and treated dairy cattle wastewater. Analyses of Escherichia coli (EC) and spores of Clostridium perfringens (CpSP) in raw and treated effluents aswell as pathogen / indicator ratios fromthe literaturewere used to estimate the concentrations of Escherichia coli O157:H7 (EC O157:H7) and Cryptospodirium spp. (Crypto) in the air, and the results were applied to an atmospheric microbiological dispersion model. From the concentrations of pathogens in the air, infectious risks for downwind receptors were calculated. The risks of infection by EC O157:H7 to workers at 10mand 50maway fromthe emission source ranged between 3.81 × 10 1 and 2.68 × 10 3 pppy (per person per year), whereas to residents at 100m and 500 m ranged from4.59 × 10 1 to 1.51 × 10 4 pppy. Peak values (95th percentile) of occupational and public risks associated with the exposure to Crypto were 3.41 × 10 3 and 6.84× 10 4 pppy at 10mand 50mfromthe source, respectively, and were lower than 1.48× 10 6 pppy regarding. exposures to CpSP. Anaerobic digestion reduced risks by approximately one order of magnitude. The distance fromthe sourcewas inversely proportional to the risk of exposure. It is recommended that wastewater is treated prior to its reuse and the adoption of application methodswith lowaerosolization potential. In addition, the need for workers to use personal protective equipment (PPE) is highlighted.
