ABSTRACT Objective To assess environmental health conditions at La Chaparrala subbasin, in the Andes Mountains of Colombia, during 2015. Method Descriptive cross-sectional study on sanitary and environmental conditions of the dwellings, as well as on immediate environment, and environmental health prejudices. A survey was applied to 117 families settled in the main axis of the creek. The physicochemical quality of the water was analyzed. Results Men were predominant as head of household, with an average of four people per house. 69 of the houses were in the urban area, while 48 were rural; the permanence was greater than 20 years for the first, and less than five years for the second. Most of the houses are owned with deeds, and 75 % of them had a connection to the aqueduct and 73 % to the sewer. The houses in the urban area were predominantly made of tile roof and tile floor, while rural houses were made of mud tile and concrete floor. Both types of construction had adobe walls. The water from the creek complied with the physicochemical parameters established in the technical regulation of the sector for drinking water and basic sanitation, and with resolution No. 2115 of 2007. Non-compliance was observed in turbidity and nitrite levels, and occurrences and concurrences on environmental health were found. Discussion The socio-demographic characteristics and environmental and health conditions of the dwellings and their surroundings are similar to those reported in Encuesta de Demografía y Salud 2010 (Demographic and Health Survey) and Encuesta Nacional de Salud 2007 (2007 National Health Survey). The creek may continue to be a source for human consumption with conventional treatment and environmental health directed to care and protect the environment, differing from the concept of World Health Organization (WHO).(AU)

OBJECTIVE: To assess environmental health conditions at La Chaparrala subbasin, in the Andes Mountains of Colombia, during 2015. METHOD: Descriptive cross-sectional study on sanitary and environmental conditions of the dwellings, as well as on immediate environment, and environmental health prejudices. A survey was applied to 117 families settled in the main axis of the creek. The physicochemical quality of the water was analyzed. RESULTS: Men were predominant as head of household, with an average of four people per house. 69 of the houses were in the urban area, while 48 were rural; the permanence was greater than 20 years for the first, and less than five years for the second. Most of the houses are owned with deeds, and 75 % of them had a connection to the aqueduct and 73 % to the sewer. The houses in the urban area were predominantly made of tile roof and tile floor, while rural houses were made of mud tile and concrete floor. Both types of construction had adobe walls. The water from the creek complied with the physicochemical parameters established in the technical regulation of the sector for drinking water and basic sanitation, and with resolution No. 2115 of 2007. Non-compliance was observed in turbidity and nitrite levels, and occurrences and concurrences on environmental health were found. DISCUSSION: The socio-demographic characteristics and environmental and health conditions of the dwellings and their surroundings are similar to those reported in Encuesta de Demografía y Salud 2010 (Demographic and Health Survey) and Encuesta Nacional de Salud 2007 (2007 National Health Survey). The creek may continue to be a source for human consumption with conventional treatment and environmental health directed to care and protect the environment, differing from the concept of World Health Organization (WHO).

Optimización del tratamiento de aguas residuales de cultivos de flores usando humedales construidos de flujo subsuperficial horizontal / Optimization of wastewater treatment from a flower crops using a horizontal sub-surface flow constructed wetland / Otimização do tratamento de águas residuárias em plantações de flores usando alagados construídos de fluxo subsuperficial horizontal

Objetivo: optimizar un sistema de tratamiento de aguas residuales de cultivos de flores, con el fin de mejorar la eficiencia en la remoción de los contaminantes, usando humedales construidos de flujo subsuperficial-horizontal. Metodología: se realizó un estudio de tipo exploratorio experimental en dos etapas, en la primera se efectuó el acondicionamiento fisicoquímico y biológico del sistema de tratamiento, en la segunda, se llevó a cabo el seguimiento de la remoción de los contaminantes durante nueve meses, para lo cual se monitoreó la demanda química de oxígeno, demanda biológica de oxígeno, sólidos totales, sólidos suspendidos totales, pH y oxígeno disuelto. Resultados: Se logró mejorar la eficiencia del sistema de tratamiento en 7,1% para la Demanda biológica de oxígeno, 4,1% Demanda química de oxígeno, 56,9% sólidos totales y 117,2% solidos suspendidos totales. Conclusión: La concentración de DQO disminuyó con el tratamiento primario (Precipitación y oxidación química) y favoreció la eficiencia del sistema de tratamiento secundario, dado que las aguas a tratar tenían valores muy altos de DQO que pueden saturar los humedales con contaminantes persistentes. Se podrían obtener mayores eficiencias, si se logra mejorar el sistema de tratamiento primario.

Objective: to optimize the wastewater treatment system of flower crops in order to improve pollutant removal efficiency, using a horizontal subsurface flow constructed wetland. Methodology: An exploratory experimental study was conducted in two stages; in the first stage the treatment system was conditioned physically, chemically and biologically. In the second stage pollutant removal was monitored for nine months. To achieve this, chemical oxygen demand, biological oxygen demand, total solids, total suspended solids, pH and dissolved oxygen were monitored. Results: It was possible to improve the efficiency of the treatment system in 7.1% for biological oxygen demand, 4.1 % for chemical oxygen demand, 56.9 % for total solids and 117.2 % for total suspended solids. Conclussion: the concentration of COD decreased with the primary treatment (precipitation, chemical oxidation) and favored the efficiency of the secondary treatment system since the water to be treated had very high values of COD which may saturate the wetlands with persistent pollutants. Higher efficiency could be obtained by enhancing the primary treatment system.

Objetivo: optimização do sistema de tratamento das águas residuárias de cultivos de flores, a fim de melhorar a eficiência na remoção dos contaminantes, usando alagados construídos de fluxo subsuperficial horizontal. Metodologia: realizou-se estudos experimentais em duas etapas, na primeira efetuou-se o desenvolvimento fisico-químico e biológico do sistema de tratamento, na segunda, o acompanhamento da remoção dos contaminantes durante nove meses, foi monitorado a demanda química de oxigênio, demanda biológica de oxigênio, sólidos totais, sólidos suspendidos totais, pH e oxigênio dissolvido. Resultados : Foi possível melhorar a eficiência do sistema de tratamento em 7,1% para a demanda biológica de oxigênio, 4,1% demanda química de oxigênio, 56,9% sólidos totais e 117,2% sólidos suspendidos totais. Conclusão: A concentração de DQO diminuiu com o tratamento primário (Precipitação e oxidação química) e favoreceu a eficiência do sistema de tratamento secundário, uma vez que as águas a tratar tinham valores muito altos de DQO que podem saturar os alagados com contaminantes persistentes. Poderiam alcançar maiores eficiências, consegue-se melhorar o sistema de tratamento primário.
