Highly Efficient

The main problems in the practice of traditional shrimp aquaculture are related with maintaining good water quality and reducing high operational cost. In this paper it will be described the application of wireless sensors and Android based application as mobile monitoring tool in achieving highly efficient shrimp aquaculture monitoring system. A set of four water quality parameter sensors (pH, temperature, conductivity and DO) were submerged into the pond using a buoy, in which an electronics and Xbee wireless transmitter have been installed to transmit the measured data into a fixed monitoring station. The main component of the fixed monitoring station was a smart data logger capable of performing automatic aeration system. Data transmission from the monitoring station to the master station was done through GSM/GPRS module of a Raspberry microcontroller. Using internet connection, a web based server has been developed from which the Android based application retrieved the measured parameter data. Graphical analysis of water quality data can be performed from a mobile phone, allowing users to monitor the aquaculture regardless of their geographical location. This system has been implemented in a shrimp aquaculture in Bangka island, Indonesia. In addition to giving real-time water quality data, the system was able to reduce the operational electricity cost because of the automatic aeration feature. Consistenly, the system has been sending the measurement data to the web server, which is accessible using Android mobile phones worldwide.

Short Pulses

As the transport of many pollutants occurs during high floods monitoring programs must focus on these intermittent events. In small rivers the pollutants start their travel as short pulses often associated with fine particles, but disperse on their way downstreams. Therefore the chemical data of a flood event are only representative of a small part of the basin adjacent to the monitoring station. This is usually not taken into account by evaluating water quality data.

Selection Of Variables

Abstract Monitoring water body quality parameters with high spatial and temporal resolutions is crucial because mitigation of pollution is usually costlier than early prevention/intervention. The existing monitoring methods for irrigation ponds in Taoyuan, Taiwan, are based on field measurements that have low spatial and temporal resolutions. In this study, using Landsat 8 satellite imagery, a multiple regression-derived relationship between the satellite band reflectance and the concentration of total phosphorus (TP) was established. The satellite imagery was atmospherically corrected with ACOLITE based on shortwave infrared (SWIR) bands. This method was used to select predictor variables in the multiple regression-derived equation based on forward selection of variables using a p-value and variation inflation factor (VIF) threshold. The derived equation yielded a coefficient of determination (R2) of 0.67. The near-infrared band (band 5) was found to be most significant. The Landsat 8 imagery retrieved for two of the three pond studies included only a few pixels from the ponds because parts of the pond surfaces are covered by floating photovoltaic power plants. The TP concentrations resulting from the derived equation indicate the feasibility of using satellite remote sensing methods to monitor the water quality. The derived relationships are potentially applicable to extend the availability of temporal and spatial water quality data for these irrigation ponds.

ABSTRACT Ultrafiltration (UF) is increasingly being recognized as a potentially effective procedure for concentrating and recovering microbes from large volumes of water and treated wastewater. Because of their very small pore sizes, UF membranes are capable of simultaneously concentrating viruses, bacteria, and parasites based on size exclusion. In this study, a UF-based water sampling procedure was used to simultaneously recover representatives of these three microbial classes seeded into 100-liter samples of tap water collected from eight cities covering six hydrologic areas of the United States. The UF-based procedure included hollow-fiber UF as the primary step for concentrating microbes and then used membrane filtration for bacterial culture assays, immunomagnetic separation for parasite recovery and quantification, and centrifugal UF for secondary concentration of viruses. Water samples were tested for nine water quality parameters to investigate whether water quality data correlated with measured recovery efficiencies and molecular detection levels. Average total method recovery efficiencies were 71, 97, 120, 110, and 91% for φX174 bacteriophage, MS2 bacteriophage, Enterococcus faecalis, Clostridium perfringens spores, and Cryptosporidium parvum oocysts, respectively. Real-time PCR and reverse transcription-PCR (RT-PCR) for seeded microbes and controls indicated that tap water quality could affect the analytical performance of molecular amplification assays, although no specific water quality parameter was found to correlate with reduced PCR or RT-PCR performance.

Transport Pathways

The causality between hydrologic parameters and water quality variations has been studied for a small upland agricultural watershed using a time-series analysis approach. The stage at the outlet of the watershed, which is a proxy for the outflow, and the average saturation deficit, which is a surrogate for the groundwater level, were used as hydrologic variables. The stages were measured at a triangular weir at the watershed outlet. The saturation deficits were obtained by means of a rainfall-runoff simulation model for agricultural upland watersheds (an extended version of TOPMODEL). Sequential water quality data were also collected at the watershed outlet. A systematic procedure for testing the causality between the hydrologic and water quality time-series is presented and used to investigate possible relationships between the two systems. The stochastic structure of a causality between hydrologic and water quality systems is shown. This stochastic structure is associated not only with the transport pathways (surface or subsurface) of each water quality parameter but also with the characteristics of the rainfall events.

Environmental Indices

Abstract The necessity of protecting our environment has promoted the development of new ways to communicate environmental information to both policy makers and the general public. In response to an increased interest in environmental indices, this paper forwards a new formulation which translates water quality parameter values into simple numerical results which can then be summed to give water quality index scores. The mechanism uses the matrix format to organize and display results with water quality parameters on one axis and common water activities on the other. The mechanism's task is then to assess the suitability of each parameter to each activity, and subsequently, to render the results into simple scores. The index can be applied to any situation in which water quality is a consideration. Its applicability lies in its offering to the perspective user the opportunity to calibrate the index to the needs of a specific situation. The procedure offers a systematic approach that is highly flexible and that generates results which are easily understood. The principal reasons for developing this index mechanism are to enable presentation of a simplified measure of water quality and to augment expert assessment of raw water quality data, not to supplant this important aspect of water quality management.
