Monitoring for Environmental Water Quality of Ramadi City: Influence of Temperature upon Chemical and Microbiological Characteristics

This report is a review of literature pertaining to the 1980 eruptions of Mount St. Helens, and to the subsequent effects of those eruptions on physical, chemical, and biological characteristics of surface water, ground water, and precipitation in the Pacific Northwest, Montana, and Colorado. Scores of studies dealing with the eruption and changes in water quality have been published; however, the data and information are contained in numerous U.S. Government and State government publications, proceedings of symposia, and a myriad of scientific journals. The salient published findings and conclusions on eruptionrelated, water-quality topics are compiled and categorized here to illustrate the scope of previous investigations. Conclusions, other than those reported by the authors listed in the Selected References, are not presented. This report contains quantitative information and descriptions of changes in the physical, chemical, and biological characteristics of water quality caused by the volcanic activity of Mount St. Helens during 1980. Lakes that received only ashfall experienced fewer effects than lakes that were within the blast zone. Phenomena occurring in new lakes created by the eruption are unique, and in some cases, had never been observed or documented prior to 1980. Different lakes are described, using a casestudy approach that includes sufficient background information on each lake to put the effects of the eruption in perspective. The changes attributable to the volcanic blast, mudfiows, and ashfall varied dramatically from one lake to another depending on the location of the lake under the ash plume, the distance of the lake from Mount St. Helens, and other physical circumstances. Similarly, the effects on rivers and streams varied in magnitude from barely perceptible changes to profound alterations that virtually created new drainage systems. Limited literature exists about the effects of the eruption on ground water. Changes in ground-water levels and chemistry are principally associated with the most heavily effected river systems those which lay in the path of mudflows generated by the volcanic eruption. Potentially toxic chemical compounds, such as phenols, were identified by researchers in several investigations. Ground-water levels in parts of the Cowlitz River system appear to have been raised above historical levels. Few studies were done about the effects of the eruption on precipitation. Observations from investigations in Colorado and Oregon suggest that physicochemical changes, such as altered specific conductance and pH of rainwater samples, were not long-lived.

The main objective of this study is to evaluate the Euphrates river at Ramadi city and Al-Dhiban canal for different purposes, and to study the variation of cations, anions, electrical conductivity, total dissolved solids, total hardness, sodium adsorption ratio and percentage of sodium for the period (1992-1998). The results indicate that water in Euphrates river at Ramadi city and Al-Dhiban canal is suitable for drinking, irrigation and for different industrial purposes according to the world and Iraqi standard except the total hardness. This exceeded the permissible limits for some months during the study interval which causes additional limitation for domestic and industrial purposes. The results also revealed an increase in parameter values in Al-Dhiban canal in contrast to Al-Ramadi location due to the effect of Al-Warrar canal and Al-Habbaniyah lake. The study concluded that calcium is the cations which are the most available elements in both locations, followed by sodium, magnesium, and potassium. As for anions it was observed that sulfate concentrations are higher than chloride concentrations.

ABSTRACTThe relation between sediment and water quality involves the individual relations between sediment and the physical, chemical, and biological characteristics of water as these characteristics determine the suitability of water for an intended use. Both the physical and chemical properties of fine‐grained sediments must be considered in evaluating these relations, whereas only the physical properties of coarse‐grained sediments are significant. Most of the literature concerning this subject has considered sediment only as a physical entity. In amount, it is the prime pollutant and is one of the major considerations in evaluating the suitability of water for an intended use. Losses in the United States from sediment and associated flood water damages are measured in billions of dollars annually. Sediments also indirectly affect water suitability through their (physical) influences on biological activity. Fine‐grained sediments, that is, clay minerals and amorphous and organic materials, have chemically active surfaces. These sediments may either sorb ions from solution or release ions to solution depending upon the chemical environment. Unfortunately, not enough is known about the ternary system–sediment‐water‐dissolved chemical load–to adequately define its influence on either the biological characteristics of water or the suitability of water for various long‐term uses. This paper attempts to define the problems concerning the role of sediment in this ternary system.

: A number of physical and chemical ambient water characteristics of the Tigris and Euphrates rivers were studied on a monthly basis over the year (2011). Samples through 61 sampling station was collected, which distributed by 39 stations along the Tigris river and 22 station along the Euphrates river. Samples collected were analyzed to find a number of variables. The variables measured include cations group (Ca, Mg Mg, Na Na), anions group (Cl, SO4), nitrate NO3, phosphate PO4, total dissolved solids TDS, in addition to measuring pH.Data were analyzed statistically to extract the results. Results showed that average concentrations of calcium ions to the Tigris River 69 mg /L, and the Euphrates River 139 mg /L. The average concentration of magnesium ions of the Tigris River is 34 mg /L, while of the Euphrates River is 67 mg /L. Average concentration of sodium ions of the Tigris River is 58 mg /L, and the Euphrates River is 247 mg /L. Average concentration of sulfate ions of the Tigris River is 154 mg /L, and the Euphrates River is 425 mg /L. Average concentration of chloride ions of the Tigris River is 98 mg / L, and the Average of the Euphrates River is 375 mg /L. Average concentration of nitrate ions of the Tigris River is 3.48 mg /L and the same average value registered to the Euphrates River. Phosphate ions concentration rate of the Tigris River is 0.24 mg / L, and the Euphrates River is 0.20 mg /L. Average concentration of total dissolved solids of the Tigris River is 530 mg / L, while the Euphrates River is 1419 mg /L. Average pH value of the water for the Tigris River is 7.6 and 7.8 for Euphrates River. Water quality of the Tigris and Euphrates rivers varies from one section to another. Water quality is better in the upstream sections of the rivers. There is a general trend to increase salinity and degradation of water quality whenever river stream Turn south because of decreasing water level and accumulation of pollution loads. Water quality of the Tigris generally better than the quality of waters of the Euphrates, where many tributaries supply Tigris river with freshwater inside Iraqi territory while Euphrates River exposed to different effluent inside Syrian territory before entering the Iraqi border. Recorded values of most variables measured of the Euphrates river greater than the values of Tigris River at the beginning of the entry of the rivers into the Iraqi border. Euphrates River compared with the Tigris River was exposed to different effluent discharges especially agricultural discharge in the central and southern regions in addition to changing hydrological conditions.

This study evaluates airborne concentrations of common trihalomethane compounds (THM) in selected living spaces of homes supplied with chlorinated tap water containing >85 ppb total THM. Three small homes in an arid urban area were selected, each having three bedrooms, a full bath, and approximately 1000 square feet; two homes had standard (refrigeration-type) central air conditioning and the third had a central evaporative cooling system (“swamp cooler”). A high-end water-use pattern was used at each home in this exposure simulation. THM were concurrently measured on 4 separate test days in tap water and air in the bathroom, living room, the bedroom closest to the bathroom, and outside using Summa canisters. Chloroform (trichloromethane, TCM), bromodichloromethane (BDCM), and dibromochloromethane (DBCM) concentrations were quantified using U.S. EPA Method TO-14. The apparent volatilization fraction consistently followed the order: TCM >BDCM >DBCM. Relatively low airborne THM concentrations (similar to outdoors) were found in the living room and bedroom samples for the home with evaporative cooling, while the refrigeration-cooled homes showed significantly higher THM levels (three- to fourfold). This differential remained after normalizing the air concentrations based on estimated THM throughput or water concentrations. These findings indicate that, despite higher throughput of THM-containing water in homes using evaporative coolers, the higher air exchange rates associated with these systems rapidly clears THM to levels similar to ambient outdoor concentrations.The data collection and preliminary data analysis were funded by defendants in a toxic tort lawsuit who were attempting to validate the accuracy of modeling assumptions and results that were offered in that litigation. The time and costs of writing this article were borne by the authors. The assistance of Tom Flahive, Gwen Corbett, Rick Hamaker, and Steve Hoyt was greatly appreciated.A poster session including the data described in this report was presented at the Society of Toxicology annual meeting and published in the following abstract: Paustenbach, D. J., Richter, R. O., Suder, D., Corbett, G. E., Flahive, T. P., and Kerger, B. D. 1998.

About one-half of the homes on First Nations (FN) reserves in Manitoba, Canada, receive piped water from a water treatment plant (WTP). Many other homes (31%) are equipped with cisterns that are filled by a water truck, and our objective was to determine how the use of cisterns affects drinking water safety relative to drinking water piped directly to homes from the WTP. The study included belowground concrete cisterns, belowground fiberglass cisterns, and aboveground polyethylene cisterns stored in insulated shelters, and all the data collection methods showed that the tap water in homes with cisterns were relatively more contaminated with coliform bacteria than the tap water in piped homes. The frequency and severity of Escherichia coli and total coliform contamination were numerically greater in drinking water samples from belowground concrete and fiberglass cisterns than in piped water samples in each community, and the contamination of belowground cisterns by coliform bacteria was greatest in late spring. As well, data obtained under the Access to Information Act showed no statistical differences in the percent of satisfactory samples (no detects) between 2014 and 2018, suggesting no clear indication of improved water quality in any of the Tribal Councils in which these three and other communities are a member off. Our results point to the need for additional treatment of drinking water in homes supplied by belowground concrete or fiberglass cisterns and replacement of belowground cisterns with aboveground cisterns or piped water to reduce the risk of water-borne illnesses.

This study aims to assess the quality of storm sewer water in Ramadi city before its discharge into the Euphrates River and Al-Warrar Canal. Several samples were taken from the storm sewer in two different periods October and April months. Samples were tested in laboratories which included (PH), electrical conductivity (EC), alkalinity (Alk), total hardness (T.H), calcium (Ca), biological oxygen requirements (BOD5), chemical oxygen requirements (COD), nitrate (NO3). sulfate (SO4) dissolved solids (TDS), suspended solids (TSS), and some heavy metals such as copper (Cu) and zinc (Zn). In this study, the authors suggested a new approach for calibrating WQI values using the multiple linear regression (MLR) model and coefficients analysis The results showed that the (MLR) model is acceptable, the multiple linear regression analysis (MLP) was applicable to calibrate WQI values, and new WQI equation with four variables was developed (SO4, BOD5, TSS and TDS), The results showed that the MLR model has a coefficient of R2 equal to (0.859), which indicates that 85.9% of the variance of the data was explained as well as obtaining significance values greater than 0.05 for each of the absolute WQI value. According to analysis, SO4 is the parameter that has the greatest effect on WQI.

This study was conducted with the aim of showing the effect of different locations and water quality on some blood enzyme properties of common carp (Cyprinus carpio L.). This study was carried out in four different locations in central Iraq for the period from June 1, 2022 to November 30, 2022. The Dujail and Suwayra sites on the Tigris River were used, and the Fallujah and Mahaweel sites on the Euphrates River were used. 120 fish were collected from the four sites, 30 fish for each site, and some biochemical traits were measured, including total protein, albumin, kinase phosphatase, glucose and total cholesterol. The results of the current study showed that the values of blood enzymes increased with the rise in temperatures during the hot months and decreased with the decrease in temperatures in the cold months. It was also found that there were highly significant differences between the Tigris and Euphrates rivers in the values of total protein, kinase phosphatase, glucose and total cholesterol, as the Tigris River was significantly superior to the Euphrates River in the values of these four enzymes, and this indicates that the Euphrates River is better than the Tigris River. As for the value of the two albums, there are no significant differences between the Tigris and Euphrates rivers. The current results also showed that there were significant differences in the values of total protein and kinase phosphatase, as these values were significantly higher in the Dujail site than in the Fallujah site, while no significant differences were observed between the Suwayrah and Al-Mahaweel sites. The current results also showed that there were no significant differences between the four sites in the value of the two albums. The current results showed higher values of blood enzymes in the Dujail site compared to the Fallujah site, and this indicates that the Fallujah site is one of the best sites in the values of enzymes, being close and within the natural limits, and this is due to the availability of an appropriate healthy environment in the Fallujah site compared to other sites.

Water quality monitoring is a very important undertaking that would ensure safe and clean water being delivered to the end users. Water quality monitoring is essential in controlling physical, chemical and biological characteristics of water. To ensure a complete and an all inclusive monitoring of the underground water and surface water, data sampling need to be carried out at many different locations within and without the study phenomenon. The current water quality monitoring methods in Zambia are mostly sparse and manual. This paper proposes the use of Wireless Sensor Networks to monitor water quality using cheap, effective and efficient sensors that have the ability to sense, process and transmit the sensed data.

Water quality is a term used to describe the chemical, physical and biological characteristics of water in respect to its suitability for a particular purpose and related with a set of standards. The knowledge of water quality and its content are essential to track any influx of water pollutants that are detrimental to human and ecosystem. The study aimed to examine the water quality status of Sg. Sarawak particularly in Waterfront and Satok Bridge based on three water quality monitoring approaches namely Water Quality Index (WQI), average NWQS and the extended NWQS (eNWQS). The eNWQS was designed based on Partial Least Square (PLS) regression where multivariate water quality data is correlated to training samples created according to the guideline of NWQS. Generally, the average NWQS and eNWQS corresponded well with the WQI in determining the river water quality status. The river water quality for both sampling points was categorized as slightly polluted with the index ranged from 62 to 68. In terms of sensitivity, the average NWQS approach was less sensitive because only discrete classes of I, II, III, IV and V were considered. The eNWQS shows better sensitivity but further study is required to verify the sensitivity level between eNWQS and WQI. This study emphasizes that the eNWQS may be useful and practical.

Water quality refers to the physical, chemical, and biological characteristics of water, and it is a measure of the condition of water relative to any human need or purpose. A particular problem with measuring the condition of water quality at drinking water reservoirs is the requirement of collecting a large number of samples. To handle this problem, we focus on the practical use of two different portable and low-cost approaches for continuous monitoring of water quality: miniboats loaded with sondes with probes and wireless sensor network- (WSN-) based monitoring system. These approaches bring several advantages over traditional monitoring systems in terms of cost, portability, and applicability. Our simulation studies show that these systems can be used to monitor water quality at drinking water reservoirs such as dams and holding ponds. Field tests to prove the effectiveness of the proposed systems are in progress.

Water quality is the term used to describe the chemical, physical, and biological characteristics of water. Furthermore, the physical, chemical, and biological characteristics of a water body, “its water quality”, determine the suitability of that water for a particular value, for example, potability, ecosystem status, agriculture, industry, recreation. Water‐quality issues have become a rapidly evolving component of the environmental sciences primarily due to the increasing demand on water resources and amenity value and the intricate linkage between water‐quality use and ecosystem health. Water quality varies markedly in time and space. Episodic temporal water‐quality variations can occur in minutes whereas, periodic variations can occur on short timescales from diurnal, associated with variations in light and temperature, to seasonal and longer associated with climatic variations. Spatial variations also vary markedly from millimeters and centimeters in soil profiles to very large‐scale variations (>1000 km), for example, associated with water residence times, lithology, landscape position, land use, and bioclimatic zone. In the absence of the effects of human activities, water quality is primarily controlled by climate (precipitation and temperature) and geology (lithology, geomorphology, soil). The water quality of a given volume of water is derived from the sum of effects of mixing and interactions from all upstream sources including atmospheric deposition (precipitation and dry deposition), soil water (matrix and macropore), groundwater, springs, wetlands, irrigation ditches and canals, streams, ponds, lakes, reservoirs, rivers, and estuaries. In most parts of the world, human activities have now caused multiple and complex changes in background water quality.

Towards Monitoring the Water Quality Using Hierarchal Routing Protocol for Wireless Sensor Networks

Silver nanoparticles (AgNPs) have been used in a wide range of industrial products. The release of AgNPs as antimicrobial agent into the river or lake can raise the ecological concern because they have been proven to be associated with toxicity of the aquatic animals. An exclusive review of AgNPs adsorbed by the various synthetic and natural adsorbent materials is important to understand the behaviour of AgNPs in the complex environmental conditions. The transformation of AgNPs into various forms in an aquatic environment depends on the physical, chemical, and biological characteristics of water. Many types of natural materials can be used to fabricate the adsorbents because pore structure, surface area, and active sites of functional groups of the adsorbent can be developed during the carbonisation and activation stages. The mass transfer factor and modified mass transfer factor models would be considered tools that can be used to describe the mechanism and kinetics of AgNPs adsorption onto the natural adsorbents influenced by the electrostatic and van der Waals forces. This exclusive review provides the valuable insights into future challenges of AgNPs adsorption to contribute to sustainable improvement in the management of aquatic ecosystems.
