Title in Portuguese
Avaliação da influência da disposição de lodo gerado por estação de tratamento de água (ETA) sobre a qualidade do solo e da água subterrânea na área da barragem Taiaçupeba, Suzano, SP

Abstract in Portuguese
A dcmanda por agua para abastecimento publico em areas com c1evado adensamento populacional envolve a producao de residuos increntes ao processo de tratamento. Na Regiao Metropolitana de Sao Paulo, a producao de agua excede 70 metros cubicos por segundo, e a geracao de lodo nas estacoes de tratamento de agua (ETA) produz elevadas quantidades de lodo. A dcstinacao desse residuo solido, atualmente, tem sido em atenos sanitarios, A caracterizacao do lodo de ETA pode definir outros usos para esse material, minimizando os impactos negativos da producao de agua. Na ETA Taiacupeba, a geracao de lodo e em media de 350 toneladas/rnes de lodo seco. A disposicao direta desse material sobre 0 solo na area da barragem de Taiacupeba foi objeto de cstudo dessa pesquisa, na caracterizacao e avaliacao do material sobre 0 solo e agua. Os resultados indicaram a presenca de metais pesados em amostras de solo+lodo na area de deposicao, sem, no entanto, ocorrer a disponibilizacao desses metais para a agua do aquifero freatico. A grande quantidade de materia organics e a indicacao de poliacrilamida residual no solo advinda do lodo sao responsaveis pelos altos teores de compostos nitrogenados na agua do aquifero.

Abstract in English
The Demand for water for public supply in areas with high population density involves the production of waste inherent to the process of treatment. In the Metropolitan Area of Sao Paulo, water production exceeds 70 cubic meters per second, and the sludge generation in the water treatment plants (WTP) is high. This solid waste has currently been disposed of in landfills. The characterization of the ETA sludge can provide other uses for this material, minimizing the negative impacts of water production. In the Taiacupeba ETA, the dry sludge generation is on average 350 tons / month. The direct disposal of this material on the ground in the Taiacupeba dam area was the object ofstudy in this research in the characterization and evaluation of the material on the ground and the water. The results indicated the presence of heavy metals in soil and sludge samples of the deposition area , without, however, having these metals available in the groundwater aquifer. The large amount of organic matter and the indicatives of residual polyacrylamide in the sludge from the soil are responsible for the high levels of nitrogen compounds in the water from the aquifer
