SUMMARY:

One of the major environmental problems of today
in urban areas it is still the inadequate final destination of solid waste. the landfills
controlled areas still continue to be a strong source of soil and water pollution,
especially the superficial ones. The present work sought to evaluate the impact of the landfill
controlled from Juazeiro do Norte – CE in the water quality of water bodies
existing in its area of direct influence. The COD parameters were verified,
OD, ST, EC, pH and T. From the physical-chemical analyzes it was observed that the
parameters that measure water pollution such as COD and OD indicate the compromised
of the water quality of the internal lagoon, with the OD well below the values
established by CONAMA 357/05, while the water from the lagoon outside the area of
waste disposal has a better quality when compared to ponds
of the area inside the embankment. Thus indicating that the controlled landfill impacts the water
surfaces in its waste disposal area. In Brazil, even with the
determination of the closure of landfills by law 12.305/2010, which sanctioned the
National Solid Waste Policy, there are serious issues involving aspects
socioeconomic and environmental factors that make such closure difficult. In Juazeiro do Norte -
EC, for example, since 2018, there has been an Area Recovery Plan
Degraded (PRAD) for the area of the old landfill. Among the measures aimed at
evaluation of the effectiveness of the performance of interventions adopted for the recovery of
This area is for monitoring the quality of surface water. However, beyond
this measure was only carried out in 2018, no more complete study has been
carried out, nor proposed in the PRAD, to assess the socioeconomic conditions and
demographic characteristics of the population living around the landfill area and waste pickers.
recyclable waste. In this context, this research aimed to evaluate the
socio-environmental degradation of the area of direct influence of the old dump in Juazeiro do
North - EC. For this, hypsometry and flow direction maps were elaborated.
superficial areas of the area, physical-chemical analyzes were performed (COD, OD, SD, pH, EC and T)
in water samples collected in natural and manure lakes, located in the area of the
landfill and its surroundings, and soil samples were collected from the said dump for analysis

of the TOC, C-labile, CSA, pH and EC parameters. For the statistical treatment of data
obtained from the analyzes of water and soil samples, the PAST software was used.
Forms containing questions related to the situation were also applied
socioeconomic and work of recyclable waste pickers, and on issues
social, health and well-being of residents adjacent to the landfill area. Starting from
obtained results it was found that, in the dry season, the average values of
COD in the leachate pond and in the natural pond inside the dump were characteristic of
manure, with concentrations of 3,383mg/L and 1754.67 mg/L, respectively,
while at the end of the rainy season, due to the dilution effect, the COD values
significantly reduced (120 mg/L, manure pond and 42 mg/L, natural pond).
Non-compliance of OD values with Resolution 357/2005 was also verified
from CONAMA, for class 2 water bodies. Finally, it was verified that the quality of the
soil, the health and quality of life of the population in the studied area were also
heavily affected by the landfill. Another group that also felt the harmful effects of
landfill were the collectors, who worked in subhuman conditions, exposed to
various risks and exhausting working hours. This group of workers had
their conditions worsened with the arrival of the Covid-19 pandemic, since
it affected his income and his mental health.
