The contamination levels were high enough to cause significantly severe effects on human health and the ecosystem (Osuji & Iruka, 2006; Osuji & Opiah, 2007; Nwankwoala et al., 2013). It is reported that surface waters had extractable petroleum hydrocarbons (EPHs) (>10-C40) concentration of up to 7420 μg/l, found in drinking water wells and 9000 μg/l benzene in groundwater (Nwankwoala & Mzaga, 2017). These values are 900 times higher than the WHO guidelines of 2009. Sediments had as high as 17, 900 mg kg−1 EPH concentrations with Polycyclic aromatic hydrocarbons concentrations values recording 8.0 mg kg−1, in most of the samples analysed. The UNEP (2011) assessment reported that the effects of the contamination have destroyed mangrove areas. Climatic conditions are favourable for natural degradation of petroleum hydrocarbon contaminants however continuous re-pollution has prevented quick environmental regeneration (Atlas, 1981; Clay 2014).","PeriodicalId":268857,"journal":{"name":"Open Access Journal of Environmental and Soil Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129893778","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}

Twenty-two species of water birds identified on the islands. Eight species of them were breeder and reminder (14 species) was passage. The dominant species was Bridled Tern Sterna Anaethetus with 170427 breeder pairs that had bred on sandy ground under the Atriplex bushes. The populations of Lesser Crested Tern Sterna bengalensis and Greater Crested Tern Sterna bergii were 19933 pairs in Nakhilou and Om-al-Gorm Islands that had bred also on the Sandy ground. The breeder population of Western Reef Heron Egretta gularis was 12, 72, and 45 pairs in Om-al-Gorm, Nakhilou, and Khan Islands respectively. The nests have been built on the short bushes. The breeder population of Crab Plover Dromas ardeola was 2266 on Nakhilou and 481 on Om-al-Gorm. The nests of this species have been built under ground in tunnels. Soil texture of tern’s nests sites in Nakhilou, Island consisted of 94.6% sand, 1.3% silt and 4.1% Clay, and under Atriplex bushes was 95.4% sand, 1.7% silt and 3.9% Clay. Soil texture of terns nesting sites in Om-al-Gorm, Khan, and Tahmadon consisted of 93.4% sand, 1.7% silt, and 4.9% clay; 92.8% sand, 2.7% silt and 4.7% clay, 89.4% sand, 3% silt and 7.6% clay respectively.

Five borings were carried out at the depths of 42.3 m and 3 m at intervals of 1m and 4.7 m respectively. The samples were taken to the laboratory for Sieve analysis, compaction test, California Bearing ratio test, plasticity index, maximum dry density, unconfined triaxial test, and shrinkage test to determine the bearing capacity of the soil. The results revealed that the subsurface displayed good bearing capacities characteristic of (1.5m and 467.20KN/m2). Settlement predictions based on a loading of 100KN/m2 indicated a settlement of 1.68 mm. Hence, the subsurface is adjudged to be suitable for the proposed construction with the expected superstructure. Seismic refraction was also carried out in the locations the geotechnical borings were made using a 12channel seismograph (Teraloc) model DPU 411 to determine the bearing capacity of the subsurface. The five selected locations that were investigated shows that the hammer source penetrated the first three layers of the earth. A software seislmager was used to analyze the data. The range of Velocities for the first three layers were 276 m/s to 1148 m/s, 544 m/s to 2270 m/s and 1134 m/s to 5368 m/s, their depths to bottom were 1. 7 m to 8.1 m and 7.2 m to 13.5 m and the shear modulus (μ) of 0.97 x 108N/m2, young modules (E) of 2.06 x 108N/m2 to 331 x 108N/m2, Lame’s constant (λ) of 0.14 x 108N/m2 to 927 x 108N/m2 and Poisson ratio (σ) of 0.01 to 0.3 were calculated, the soil identified in the survey area were mainly sand, clay, shale, gravel, and granite. Seismic refraction and geotechnical results show a good agreement that the soil is well consolidated, and it is suitable for the expected deep foundation building.","PeriodicalId":268857,"journal":{"name":"Open Access Journal of Environmental and Soil Sciences","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128563794","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}
