Testing and analyzing the water quality had been conducted by combining several characteristics of sensors (temperature, turbidity and heavy metals) integrated in the wireless network system to determine the quality comparator parameters of water worth drinking in coastal areas. Using sensors made of chitosan compounds to detect heavy metals contained in water. Testing was also done using the DS18B20 sensor (temperature) and TDS (salt levels) by operating a wireless network to transmit data in real time to the web through the GPRS network with the automation system. The sampling used purposive sampling by seafront distance, ± 1 km distance and ± 3 km distance. Testing of copper chips with the addition of Chitosan showed a more stable reading result than without using copper plates (read: pure PCB). At Chitosan biosensors, the addition of CMC shows more varied readings compared to using chitosan biosensors alone. The Ds18b20 Sensor was able to work at high temperatures, with stable value readings. From Sensor readings TDS (EC meter), it’s obtained that the higher the water solution, the greater the reading from the TDS sensor. It was shown on a chart that describing the closer to the sea area, the higher the level of the dissolved substances. The tool was accessed in real time through the Thing Speak platform in accordance with the specified account.

This paper presents the transformation of the water system of the Education City in Doha (Qatar) into a smart water system. This city covers an area of 14 km2 and includes 80 buildings. The water system provides drinking, irrigation and fire protection services. It suffers from the use of fragmented management systems and from a lack of real-time monitoring, which result in a deterioration of efficiency of the water system and users’ information The paper describes the water system and then the architecture of the smart water solution and its use for leak detection, water quality control and operation safety.

Irrigation Water Quality

In order to provide the real-time monitoring for identifying the sources of pollution and improving the irrigation water quality management, the integration of continuous automatic sampling techniques and cloud technologies is essential. In this study, we have established an automatic real-time monitoring system for improving the irrigation water quality management, especially for heavy metals such as Cd, Pb, Cu, Ni, Zn, and Cr. As a part of this work, we have first provided several examples on the basic water quality parameters (e.g., pH and electrical conductance) to demonstrate the capacity of data correction by the smart monitoring system, and then evaluated the trend and variance of water quality parameters for different types of monitoring stations. By doing so, the threshold (to initiate early warming) of different water quality parameters could be dynamically determined by the system, and the authorities could be immediately notified for follow-up actions. We have also provided and discussed the representative results from the real-time automatic monitoring system of heavy metals from different monitoring stations. Finally, we have illustrated the implications of the developed smart monitoring system for ensuring the safety of irrigation water in the near future, including integration with automatic sampling for establishing information exchange platform, estimating fluxes of heavy metals to paddy fields, and combining with green technologies for nonpoint source pollution control.

Artisanal Gold Mining

Introduction: Unsustainable natural resources utilization is on the increase in the developing countries thus the ability of many local communities to meet their basic needs including food, water and shelter is jeopardized. Uncontrolled gold-mining in Sikasso region is one such an anthropogenic activity that is of great environmental concern to the local and national governments of Mali owing to its potential impacts on water quality, human health and environment. This study was conceived to assess the impacts of artisanal gold mining on water quality in Tangandougou in Sikasso region of Mali.Materials and Methods: In this descriptive study, water samples were collected, processed and analyzed for heavy metals (Lead, Cadmium and Arsenic) according to APHA protocols. Measurements of physical parameters of water quality were done according to APHA protocols. Data were analyzed using both descriptive and inferential statistics.Results: There were no significant spatial differences in physical and chemical parameters (pH, Temperature, Conductivity, total dissolved solids and Salinity) of water quality amongst the sampling sites. However, the heavy metals concentrations in the sampled water exceeded WHO drinking water quality guidelines.Conclusion: It was concluded that the water of Sankarani River and its tributaries is contaminated and may cause adverse effects on human health due to biomagnification and the bioaccumulative nature of heavy metals. Therefore, the study recommends continuous monitoring of the water quality in all water sources adjacent to gold-mining areas to protect human and environmental health.

The quality and the temperature of pond water is an important parameter that need to get attention in fish cultivation. Every type of fish has their own characteristic towards water condition and pond temperature. The monitoring of water quality in cultivation pond is done manually and it takes a lot of time. The purpose of this research is to design web-based control system device and monitoring the quality of the water of fish cultivation pond including salinity, temperature and the hardness in real time using special application. This device design consists of salinity sensor, hardness sensor, and temperature sensor. Temperature can be controlled and monitored automatically on the application via computer/laptop. The result of this research is temperature drop by 0,1 oC on a 10 liters pond that takes 18 seconds, and to decrease the temperature of 1 oC takes 180 seconds (3 minutes). To raise the temperature of 0,1 oC takes 264 seconds or 4,4 minutes, and to raise the temperature of 1 oC takes 2640 seconds or 44 minutes. The percentage of error for sensor reading is ranged 2,4% - 3,9%.

This paper presents a study on assessment of water quality. According to a study, mining activities have a significant impact on water quality (lakes, surface water and groundwater), which has become a major problem globally. Due to mining and exploitation processes, lakes can be formed around these mines. Also, these lakes have been formed around the world and are steadily increasing. The purpose of this study is to watch the quality of water from the area around mining activities. This study refers to the, Groapa Burlacu lake around the mining exploitation Targu Ocna, Romania. This lake was formed on the northern bottle of the massive salt, strongly affected by the underground activities. Sampling for the determination the concentrations of Cl- and NaCl from the studied area was made at different depths (0 m, -5 m, -10 m, -15 m, -20 m, -25 m, -30 m, -35 m -40 m). Besides these concentrations, physical parameters of the water (pH, turbidity, electrical conductivity, dissolved oxygen and temperature) were also measured. To determine the physical parameters in the monitored area, sampling was done from four different points of the area and then put together for analysis. These parameters were measured on site using portable equipment. The data on the analyzed concentrations indicate that at depths of less than 5.0 m, the NaCl concentration values are more than 250 g/L.
