| Resumo: | The municipality of Guamaré is located on the north coast of RN, Salineira zone, with
a land area of 259 km2 and a population of approximately 12,500 inhabitants (IBGE, 2010).
Presents strong morphological instability caused mainly by the influence of human activities
in the region. The present study aims to assess the existing levels of salts in the springs of the
region, by evaluating the electrical conductivity, pH, salinity, chlorides, hardness, calcium,
magnesium and heavy metals in the water. The collection and analysis methods adopted in the
survey are based on APHA (2005). The electrical conductivity, salinity and chloride behaved
similarly throughout the study. Some points suffered the direct effect of the salt ponds and
others. Given the existence of a drainage ditch between the saline and monitored region, there
was little change in the environment, including the native vegetation. The opposite situation
occurred in farms where the region is fully committed local vegetation and water holes and
wells used in the past for domestic use are practically disabled (high salt content). In Rio
Miassaba formation of an estuary is reversed, with the farther out from the sea showing higher
salt concentracions, which may be associated with the discharge of organic matter and natural
evaporation rate. In periods of no rainfall had a few points higher than the levels of salts
found in seawater and may be associated with high evaporation in the region. Detected a
positive factor is the high resilience and reducing salt, after periods of rainfall incidence |
