“…Estudios previos reportan en el agua y sedimento de esta zona del CARL, compuestos orgánicos persistentes (COP) entre los cuales se encuentran el nitrobenceno, terfenil, 2 fluorobifenil, fenol d6, 2 fluorofenol, 2,4,6 tribromofenol, entre otros, así como los metales cromo, cobre, zinc y plomo, todos ellos considerados como tóxicos para la biota acuática (Tejeda et al 2005, Carreño 2008, Zarazúa 2008. Debido a las condiciones fisicas y químicas de este cuerpo de agua, la anoxia, la alta concentración de la demanda química y bioquímica de oxígeno (Hinojosa 2006, Zarazúa 2008, es que los contaminantes orgánicos persistentes y los metales pueden asociarse a otros compuestos y/o elementos, formando compuestos insolubles y así, depositarse en el lecho de los sedimentos con lo que se incrementaría su concentración, enriquecimiento y toxicidad (Coz et al 2008, Karlsson et al 2010.…”

“…Análisis físicos y químicos de los sedimentos A cada muestra de sedimento se le determinó el pH con un potenciómetro marca "Hach" (SCOFI 1984) y el contenido de carbono orgánico total (COT) con un analizador elemental "OI Analytical". Se seleccionaron estos parámetros ya que pueden influir en la toxicidad y movilidad de los contaminantes (Coz et al 2008, Karlsson et al 2010). …”

Palabras clave: microtox®, contaminación en agua RESUMEN El objetivo de este estudio fue determinar la toxicidad de los sedimentos del curso alto del río Lerma (CARL), Estado de México, por medio del ensayo Microtox® con el protocolo básico en la fase sólida. Se colectaron muestras de sedimento superficial en 23 sitios distribuidos sobre el CARL: 12 sobre el cauce del río y 11 en sus tributarios, durante dos campañas de muestreo en un periodo de un año. La concentración efectiva media (EC50) en Vibrio fischeri varió para los sedimentos riverinos entre 139 mg/L y 3588 mg/L y para los de las descargas fue entre 108 mg/L y 16436 mg/L. En general los sedimentos del CARL pueden clasificarse como extremadamente tóxicos, lo cual es un indicativo del impacto de las contribuciones antrópicas de origen doméstico e industrial que recibe este importante cuerpo de agua. Key words: microtox®, water pollution ABSTRACTThe aim of this study was to evaluate the toxicity of sediments in the upper course of the Lerma River (UCLR), in the State of Mexico by means of Microtox® test using the basic solid phase test protocol. The surface sediment samples were collected in 23 sites distributed following the main stream flow of the river: 12 on the river and 11 on its tributaries for two sampling campaigns in a one year period. Half maximal effective concentration (EC50) in Vibrio fischeri varied in the river sediment from 139 mg/L to 3588 mg/L and for the tributaries it varied between 108 mg/L to 16436 mg/L. In general, sediments of the UCLR can be classified as extremely toxics which show the impact of anthropogenic contributions that come from urban and industrial untreated discharges.

“…In addition, the TSS removal had a moderate impact on particulate Cd and NH 4 -N, indicating that it is a good predictor of pollutant removal efficiency. The difference in TSS removal between the 13 storm events could be attributed to the high variability in the inlet TSS concentrations which are, themselves, most likely attributable to the effect of ADDs (Revitt et al 1999;Karlsson et al 2010) and/or rainfall intensity (Nie et al 2008;Francey et al 2010). However, the outlet TSS concentrations were relatively stable year-round.…”

This study monitored the stormwater runoff quantity and quality treatment performance of a 6.8 ha 19-year old combined pond-wetland system, located in south Sweden, over one year. The mean volume reductions for 53 storm events for the pond and wetland were 40% and 28%, respectively, while the mean flow reductions were 60% and 76%, respectively. Pollutant concentrations in the influent to the wetland were highly variable. The pond-wetland system could efficiently remove an average of 91%, 80%, 94%, 91%, 83% and 92% of TSS, TP, particulate Cd, Cu, Pb, and Zn, respectively, whereas the removal of particulate and dissolved Ni was highly variable with an average of 67% ± 62% and −5% ± 41%, respectively. The removal of TN, NH 4 -N and NO 3 + NO 2 -N was highly variable with an average of 45% ± 27%, 12% ± 96% and 45% ± 43%, respectively. These removal percentages are high in comparison to other studies and underline that relatively old systems can also provide efficient treatment. Although the pond accounted for a substantial reduction of pollutant concentration, the wetland significantly enhanced both the treatment performance and the peak flow reduction. This underlines that a combined pond/wetland system is a more beneficial solution than a pond only. The pollutant removal efficiency was significantly influenced by some factors including Antecedent Dry Days, seasonal variations, air temperature, retention times, rainfall depth and duration, and peak rainfall intensity.

“…Downstream ecosystem health impairment is possible due to pollution found in pond sediment. A large percentage of the metals in sediment are in potential mobile forms and pond sediment can display a toxic response (Karlsson et al, 2010;Marsalek & Marsalek, 1997). A specific examination of 30 pond and wetland forebays illustrated that certain metals frequently (up to 50% of the time) reach levels of toxicity in captured forebay sediment (McNett & Hunt, 2011).…”

Great investment is made in the design and installation of stormwater control measures (SCMs). Substantial research investment, too, is made to optimise the performance of SCMs. However, once installed, SCMs often suffer from lack of maintenance or even outright neglect. Key maintenance needs for wet ponds, constructed stormwater wetlands, bioretention, infiltration practices, permeable pavement, swales, and rainwater harvesting systems are reviewed with many tasks, such as the cleaning of pre-treatment areas and the preservation of infiltration surfaces, being common maintenance themes among SCMs. Consequences of lacking maintenance are illustrated (mainly insufficient function or failure). Probable reasons for neglect include insufficient communication, unclear responsibilities, lack of knowledge, financial barriers, and decentralised measures. In future designs and research, maintenance (and lack thereof ) should be considered. Assessing the performance of SCMs conservatively and including safety factors may prevent consequences of under-maintenance; and requiring regular inspection may help to enforce sufficient maintenance.
