This book was released on 2021 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, Lake Erie has seen a surge in harmful algal blooms that are largely attributed to agricultural runoff in the Maumee River Watershed. Local action and public influence can improve local water quality, but changing behaviors relies on an understanding of the beliefs or perceptions that motivate action. A better understanding of what influences public perceptions of local water quality and how accurate these perceptions are compared to actual water quality may be necessary to motivate local pro-environmental behavior. There is not currently a consensus about how different factors will influence public perceptions and accuracy of water quality. Although there is a clear focus in the literature on how organoleptic properties drive public perceptions (e.g., a water body is considered good if it smells and looks good). This study uses observational water quality data combined with perceptions of water quality to determine how demographic factors (such as age, gender, education, income, and proximity) and information environments (such as issue attentiveness, issue understanding, and trust in stakeholders) influence local perceptions and the accuracy of those perceptions in the Maumee River Watershed. Our results indicate that demographic factors are poor predictors of both perceptions and accuracy, while the most predictive factor was a respondent’s trust in agricultural stakeholders. Specifically, we find that water quality is more likely to be perceived as good and better than it actually is among those who highly trust agricultural stakeholders. This suggests that future research and communication efforts should focus on how different channels of communication are presenting local water quality issues. In this area with a particularly large agricultural influence, these results may indicate that individuals are motivated to believe the water is better than it is due to their agricultural interests. On the other hand, they may actually be receiving information from agricultural stakeholders that downplays local issues, versus information from environmental stakeholders that may overstate the problem.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding water quality dynamics in recreational rivers is integral in shaping management strategies that maintain ecosystem health, perceived value and appeal, and regional economic significance in a changing environment. Optical water quality describes the behavior of light in water as governed by its physical and chemical composition, and is among the strongest influences on human perceptions of water quality. Ethnohydrology is the study of culturally constructed knowledge and understanding of water. This work is the culmination of an interdisciplinary approach to water resources research -- integrating optical water quality and ethnohydrology methods to recognize the intersection between measured water quality and visible characteristics influencing human perceptions. Relationships among particulate concentrations as a function of the hydrograph during receding flow in five popular recreational rivers of the southwestern Ozarks of Arkansas, USA were dependent upon catchment characteristics, and optical water quality measures may be well-suited for describing these dynamics in the absence of more intensive monitoring programs. Measurement of horizontal black disk visibility was a particularly accessible and intuitive scientific tool for characterizing optical water quality and suspended sediment variability. Analyses of 167 surveys and pile-sorts deployed at regional events indicated that, despite some variability, individuals may use similar cognitive processes to discern differences among images of aquatic conditions in rivers, and these judgments can be directly linked to optical water quality measurements. This work suggests important physical and chemical parameters of water quality may be communicated meaningfully across stakeholders in terms of how they relate to visible attributes, thus expressing water quality in terms of its true meaning to society and the environment.

This book was released on 2011 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: State and federal agencies measure water quality in streams using different sampling regimes. The Ohio EPA uses geometric sampling of 80+ sites in 11 digit HUC watersheds, whereas the US EPA uses probabilistic sampling of 25 sites in Ohio. I analyzed OEPA fish (IBI) and macroinvertebrate (ICI) indices from 9 watersheds (3 agricultural, 3 urban, and 3 with little disturbance) along with US EPA data. Results suggest that the number of sites sampled by OEPA is insufficient to reproduce statistically similar IBI or ICI scores. Most sites should be sampled on third order streams and the least on first and fifth order streams. Similarly, more sites should be sampled in agricultural watersheds than in least disturbed or urban watersheds. IBI scores from OEPA and US EPA were positively correlated, but ICI scores were negatively correlated. Both OEPA and US EPA need to collect more data to manage and improve watersheds.

Download or read book Assessing Effects of Sampling Frequency on the Estimation Accuracy of Different Water Quality Indicators written by Lin Gao and published by . This book was released on 2017 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field sampling is an important component of water quality assessment and for early detection of water quality deterioration caused by human activities. Theoretically, the accuracy of water quality indicators estimated from water samples should increase with increasing the number of samples or the sampling frequency. However, costs related to water sample collection, transportation, storage and laboratory analyses, will also increase with increasing sampling frequency. It is a challenge to determine an adequate sampling frequency that achieves both acceptable accuracies for estimating the change in water quality indicators and acceptable cost for sample collection and laboratory analyses. The objective of this study was to analyze the effects of variation in sampling frequency on the accuracy of selected water quality indicators. Water quality variables analyzed in this study include suspended solids (ton ha-1), and concentrations of agricultural nutrients (nitrate nitrogen potassium, ortho-phosphorus, calcium, and magnesium). Water quality indicators included in this study were annual loading and Concentration Exceedance Frequency (CEF). Water quality data from Little River Watershed and its tributary Black Brook Watershed in New Brunswick were used to generalize the relationship between the estimation accuracy of the above-mentioned water quality indicators and the different sampling frequency by statistical approaches. The coefficient of variation, the relative bias, and the probability of potential error were used as measures of estimation accuracy. Results indicated that these three measures of estimation accuracy in annual loading decreased with increasing sampling frequency for sediments and all agricultural nutrients. As expected, these measures of estimation accuracy in CEF also decreased with increasing sampling frequency. This means accuracies of both annual loading and CEF increased with increasing sampling frequency.

Available in PDF, EPUB and Kindle. Book excerpt: Analysis of water quality data and landuse/landcover changes are important aspects of water quality management. This study examines water quality trends within the Cuyahoga and the Maumee Rivers using U.S Geological Survey and Ohio Environmental Protection Agency data collected from 1976 through 2003. Landuse/landcover changes for the watersheds were determined using Landsat imagery. Trend analyses performed using an ANCOVA model revealed a decrease in point source load and ambient concentration of ammonia plus organic nitrogen and phosphorus for both rivers. Nitrite plus nitrate concentration for the Cuyahoga River increased but decreased in Maumee River. Nitrite plus nitrate load increased in both rivers. A post-classification comparison technique showed an increase in forests for the Cuyahoga basin and an increase in agriculture for the Maumee basin. The study concludes that the general improvement in water quality seems to be the result of effective BMPs.

Available in PDF, EPUB and Kindle. Book excerpt: Data on water quality and other environmental issues are being collected at an ever-increasing rate. In the past, however, the techniques used by scientists to interpret this data have not progressed as quickly. This is a book of modern statistical methods for analysis of practical problems in water quality and water resources. The last fifteen years have seen major advances in the fields of exploratory data analysis (EDA) and robust statistical methods. The 'real-life' characteristics of environmental data tend to drive analysis towards the use of these methods. These advances are presented in a practical and relevant format. Alternate methods are compared, highlighting the strengths and weaknesses of each as applied to environmental data. Techniques for trend analysis and dealing with water below the detection limit are topics covered, which are of great interest to consultants in water-quality and hydrology, scientists in state, provincial and federal water resources, and geological survey agencies. The practising water resources scientist will find the worked examples using actual field data from case studies of environmental problems, of real value. Exercises at the end of each chapter enable the mechanics of the methodological process to be fully understood, with data sets included on diskette for easy use. The result is a book that is both up-to-date and immediately relevant to ongoing work in the environmental and water sciences.
