However, supply companies have problem to ensure this efficiency due to several structural factors – among these, they can be cited: the age of the distribution networks, the type of material used, the depth, location and the lack of information about the pipes. Thus, this study aimed to carry out the mapping of the asbestos cement pipe in water distribution network of the county of Princesa Isabel – PB. For this, the following methodology was established: collecting information through reports and application form about the distribution network, systematization of data, field demarcation of the points where there was asbestos cement pipe and digital mapping of this pipe using the Google Earth software. From the mapping, it was realized that the asbestos cement pipe covers the central area of the county, covering half of the total pipe water distribution network. In this sense, the map prepared at this research could contribute information relevant to the future replacement of the pipe under study, as well as provide initial data to the onset of new research and database creation.","PeriodicalId":31439,"journal":{"name":"Revista Principia","volume":"36 1","pages":"69-76"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67739824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides, it also highlights the potential risk of contamination of the shellfish. The study was developed in the area of shellfish extraction, located in Paraíba River, in CabedeloPB. The samples were collected from three sandbanks. In each sandbank two points three times, between the months of May and August of the year 2014, totalizing an amount of 18 samples analyzed. The parameters (temperature, turbidity, pH, electric conductivity, dissolved oxygen (DO), ammonia, nitrite and phosphate) were evaluated following the methodology of APHA (1998). The results ratify the existence of activities that cause the elevated concentration of the content of ammonia and the low level of DO in the water environment. The dynamics of the tide and the physical conditions of the environment accelerate the reaction of nitrification. The concentrations of phosphate and nitrite were in the maximum limit established by the resolution number 357/05 of the CONAMA. Considering the potential risks of the contamination of the shellfish due to hydric pollution, it is necessary an intervention of inspection agencies in relation to the direct disposal of solid and liquid wastes in the estuary as a way of warranting the integrity of the water environment and the health of consumers.","PeriodicalId":31439,"journal":{"name":"Revista Principia","volume":"1 1","pages":"47-54"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67738229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
