• Abstract:

  Cemeteries represent social facilities that deserve the attention of managers and planners of public sanitation policies with an emphasis on health, water use, soil and territorial planning. Since the products generated by cemetery activities, such as necrochorume, trace metals and pathogens, cause negative environmental impacts to soils, water, edaphic and aquatic biota and risks to public and collective health. This article aimed to investigate the level of influence of the Complex of cemiteries: Quinta dos Lázaros (CCQL), Salvador, Bahia, Brazil, on the chemical and microbiological contamination of groundwater by the product of cadaveric decomposition (necrochorum). Groundwater samples were collected in tubular wells and water from sources, measuring in situ the physical-chemical parameters, with the aid of a multiparameter probe (Horiba U-50), taking aliquots for chemical and microbiological laboratory analyses, carrying out a spatial analysis of geoenvironmental aspects such as modeling and land uses. The results of ammoniacal nitrogen, nitrate and microbiological indicators indicated the loss of water and socio-environmental quality, and local restrictions on use, including potability, in disagreement with Consolidation Ordinance No. 888/21, whose use of these waters represents a risk factor for exposure to pathogens and pollution. It is concluded that the results of the chemical and microbiological analyzes of the water and the spatial analysis of geoenvironmental aspects pointed to an environmental change associated with the activities of the CCQL, which demand environmental monitoring, health surveillance and the framing of the area of ​​influence to the legislation, as provided for CONAMA Resolutions no. 357/05, no. 368/06, number: 402/08, NBR 10.157/87, NBR 15.495-1/07 and NBR 15.495-2/08.
