A Secretaria de Meio Ambiente e Urbanismo (Semurb) recebeu na \u00faltima ter\u00e7a-feira (18) o resultado da an\u00e1lise microbiol\u00f3gica da \u00e1gua coletada, em 3 de fevereiro, pr\u00f3ximo ao Morro do Careca, em Ponta Negra. O laudo confirma que n\u00e3o se trata de esgoto, mas de afloramento do len\u00e7ol fre\u00e1tico, naquele local.<\/p>\n\n\n\n
A an\u00e1lise f\u00edsico\/qu\u00edmica, realizada pelo Instituto Federal de Educa\u00e7\u00e3o (IFRN), campus Natal\/Central, apresentou de fato a ocorr\u00eancia de nitrato, caracter\u00edstico de oxida\u00e7\u00e3o de mat\u00e9ria org\u00e2nica h\u00e1 v\u00e1rios anos, tem odor caracter\u00edstico, mas n\u00e3o tem presen\u00e7a de coliforme fecal, ou seja de esgoto, disse o supervisor geral de Fiscaliza\u00e7\u00e3o Ambiental da Semurb, Leonardo Almeida.<\/p>\n\n\n\n
Esse fen\u00f4meno de afloramento de len\u00e7ol \u00e9 explicado pelo ge\u00f3grafo e fiscal ambiental da Semurb, Gustavo Szilagyi. Segundo ele, o litoral potiguar \u00e9 formado pela jun\u00e7\u00e3o de barreiras e dunas, que ficam sobrepostas. As dunas atuam como filtros naturais e quando as \u00e1guas encontram a forma\u00e7\u00e3o barreiras, que atuam como uma capa imperme\u00e1vel, ela come\u00e7a a escorrer para o mar, foi o que ocorreu em Ponta Negra. \u201cComumente iremos observar esses afloramentos ap\u00f3s per\u00edodos de chuvas intensas, como a que tivemos agora no final de janeiro”, explica ele.<\/p>\n\n\n\n
Segundo ele, essa \u00e1gua rica em mat\u00e9ria org\u00e2nica j\u00e1 decomposta e que s\u00e3o formadas por nitratos, como a pr\u00f3pria an\u00e1lise laboratorial mostrou, gera um odor c\u00edtrico caracter\u00edstico, muitas vezes, leva as pessoas a deduzir que se trata de um esgoto. \u201cMas na verdade \u00e9 apenas \u00e1gua do len\u00e7ol fre\u00e1tico, aflorando na praia, portanto, n\u00e3o gera preju\u00edzo \u00e0 sa\u00fade p\u00fablica\u201d, afirmou Szilagyi.<\/p>\n","protected":false},"excerpt":{"rendered":"
