Resumo:
This paper proposed agribusiness activities correlate with human and environmental
health, and the Irrigated Perimeter of São Gonçalo - PB, as a study. For this we
analyzed the raw and treated water coming from said perimeter, through physical,
chemical and microbiological parameters, such as increased under investigation. The
research is characterized quantitative, qualitative and descriptive nature. Eight
sampling were geocoded, and four points were raw water and treated water four. The
collections were made in 2012, for six months, for April, May and June as period and
reverse, October, November and December as the dry season. And he made a
survey of the basic indicators of health and environmental conditions that directly
influence human health and the ecosystem. The physico-chemical and
microbiological outcomes were assessed based on the current legislation. Thus, it
was found that both samples of raw water and treated in relation to physico-chemical
properties, these remained within permitted limits (CONAMA Resolution 375/05 and
MS Portaria No. 2914/11, respectively). The microbiological results found presence
of coliforms, total and thermotolerant presence for raw water samples, in both winter
and summer periods. The criteria for bathing waters showed satisfactory these same
aspects for the A3 and A4 point (see point analysis) and unfit for A6 and A8 points
(CONAMA Resolution 274/2000). Thus, the treated water showed foci of microbial
contamination at all points, observing the boundaries of the MS 2914/2011, by the
presence of total coliforms. Samples of treated water showed that the housing units II
and III (and NHIII-2 NHII-2) showed values of more than Probable Number (MPN) of
total coliforms and thermotolerant high, it is believed that such contamination is
attributed to poor maintenance the hydraulic network, and / or inefficient cleaning. It
is important to mention that the average rainfall in 2012, survey period, was lower
than expected, contributing to a significant decrease in the total volume in cubic
meters ( m³ ) Açude of São Gonçalo. This situation is worrying because, with the
decrease of water promotes the process of eutrophication. After analysis of the
indicators, it was concluded that such situations, for example, the supply and
treatment of water, Sewage facilities and solid waste, reflect a pre-condition to the
population as diseases can also compromise the agribusiness activities developed in
the irrigated area under study.
