“…The wider issues regarding the excessive use of nitrate fertilisers for the growth of vegetables and the need to apply the legal limits already in operation in Switzerland and Holland have been discussed elsewhere (9,10). We wish to thank Dr. John Potter and Dr. Peter Bond, Principal and Head of Science Department respectively, Farnborough College of Technology and the Geoffrey Taylor Foundation for its continued financial support.…”

“…The maximum permitted N-NO 3 is 10 mg/L, whose concentration has been established on international drink-water quality legislation to avoid the methemoglobinemia. This disease could cause the death of children and aged between nitrate and nitrite ingestion and the occurrence of some cancer types, and worldwide the public policies neglect this fact, and do not define a maximum value for such risks (WALTERS, 1983).…”

This research aimed to investigate the relation between sanitary situation and groundwater quality, using the concentration of nitrogenous compounds. The aquifer studied is unconfined and situated in the periurban zone of Fortaleza (NE Brazil). Through the Geographic Information System (GIS), a relational database was created using data from the IBGE demographic census (2011), to analyze numbers of households linked to septic tanks or rudimentary cesspit. The groundwater quality was evaluated based on nitrogen compounds (N-NH3 +; NO2 -; N-NO3 -), pH, and total dissolved solids (TDS). The highest concentrations of nitrates are found in areas with a higher density of septic tanks and rudimentary cesspit. Furthermore, nitrate was more present in water table above 6.6 m, mainly in the interfluvial zones, which have a high oxidation potential. The results contribute to the loss of contamination, based on the number of households with septic tanks and rudimentary cesspit, in unconfined aquifers, which were more vulnerable to contamination, mainly in peripheric expansions areas in the cities, where the deficit in sewage services tends to be high.
