Environmental factors in the form of soil and water quality are the important factors of aquaculture pond productivity, including total production (tiger shrimps, Penaeus monodon, and milkfish, Chanos chanos) in Pasuruan, East Java Province. The objective of this study was to analyze the direct or indirect effects of soil and water quality on the total production of ponds in Pasuruan using a path analysis application. Data were collected in the pond areas around Pasuruan Regency including Nguling, Lekok, Rejoso, Keraton, and Bangil Sub-Districts as well as Pasuruan City. Soil quality was determined as a free variable and exogen; water quality as mediate variable, suspended, and endogen; as well as milkfish production as suspended variable and endogen. Environmental characteristics were illustrated using descriptive statistics, while environment factor effects on total production were analyzed using path analysis. The results of path analysis show that from the 12 analyzed soil quality variables, only two variables were affected in the total production of pond (tiger shrimps and milkfish) namely: contents of soil organic carbon and soil phosphate. While based on 11 water quality variables, two variables (water salinity and water iron) were affected the total production of ponds in Pasuruan Regency. The direct effects of soil organic carbon and phosphate on the total production were 0.314 and -0.600, respectively. Water salinity and water iron gave direct effects on total production amounting to -0.678 and 0.358 respectively. It is also found that two soil variables which were affected in the total production, did not indicate the effect towards water quality in ponds. Further implication of this research is put more attention for these variables into pond’s management in order to gain more production. Technical application could be appropriate for pond preparation and frequently water changing during grow out.

“5.12 Wenchuan earthquake”triggered floods, landslide, collapse and secondary geological disaster, trigger a new soil and water loss, having the significant influence to the local river water quality.This article through the statistical analysis of minjiang river and jiangyou wenchuan, beichuan station 2006 ~ 2011 water conditions material, discussing the before and after the earthquake disaster areas of river water quality change characteristics. The results showed From ammonia nitrogen source analysis, urban sewage and industrial waste water, agricultural non-point source pollution and earthquake that triggered the new soil and water loss is the main pollution source. Based on the hydrological site total hardness concentration prediction, we can find wenchuan earthquake disaster area total hardness concentration significantly increase trend.

The aim of this study is to evaluate the potential impacts of 8.5 MW thermal power plant on soil and water quality within its location, Lekki area, Lagos State. The study area was geo-referenced using the existing map and Geographical Positioning System. Auger was used to sample soil at three different locations within the power plant. The soil samples were prepared and analyzed for the following parameters using standard analytical methods. The parameters include soil texture, Exchangeable cations and anions (H+, Na+, Ca2+, Mg2+, Cl- and SO42-) Nutrients compounds (NO3-, Total Nitrogen (TN), Organic Carbon (OC) and heavy metals (Fe, Cd, As, and Mn). Surface and groundwater samples were collected within the power plant in triplicate and analyzed for true colour, turbidity, conductivity, salinity, THC and Coliform. Dissolved Oxygen (DO), BOD5, Total Organic Carbon (TOC), Organic Matter (OM) and heavy metals (As, Ag, Fe and Mn) of water samples were also analyzed. The soil from the study area is loamy-sand in texture. The average As, Ag, Fe and Mn in surface and groundwater samples were 0.055, 0.025, 3.150, 0.735 and 0.12, 0.080, 6.440 and 0.180 mg/L, respectively. The gas-fired power plant has contaminated the soil and water within its premises with petroleum and heavy metals. The engine stack should be modified to minimize the pollution effects of the power plant on the environment.
