Resumen:
Abstract.- To test the effect of the treatment plant of theMar del Plata city, a series of samplings were carried out in themussel beds around the sewage effluent. The hypothesis is thatthis treatment plant produces an effective mitigation processin the health of the environment, and cover and quantitativemethods produce similar results being both useful for assessingsewage impact in intertidal mussels community. Samplingswere performed in four locations (Impacted, North, South andControl) and three stations were placed into each location.Replicated cover (ten 0.5 m2 squares) and quantitative (four78 cm2 corers) data were obtained in each station four timesduring 2004, before and after each of the two stops of thetreatment plant for maintenance. Analyses included nonparametricand parametric methods for both cover andquantitative data. Results showed significant differences in bothcover and quantitative data for Before-After and amonglocations, in both parametric and non-parametric analyses. Thefunctioning of the treatment plant has a significant effect onthe health of the environment, as shown by the structure of theintertidal benthic community.
