2007 Lake Monitoring Report Mecklenburg County Water Quality Program SWIM Phase I Part 2-CO
2007 Lake Monitoring Report Mecklenburg County Water Quality Program SWIM Phase I Part 2-CO Prepared by: David Buetow Final Report for FY2007-2008 PURPOSE AND BACKGROUND The Mecklenburg County Water Quality Program (MCWQP) has an ongoing program to monitor the water quality in the three Catawba Lakes bordering the county: Lake Norman, Mountain Island Lake and Lake Wylie. Samples are also routinely collected at the two water bodies in the northern end of Mecklenburg County cut off from Lake Norman proper by I-77: Lake Cornelius and Lake Davidson. Data collected from all lake sites are used to screen for environmental problems using MCWQP Action and Watch levels for various pollutants and also to rate the overall water quality at sampling locations in the lakes using a water quality index. Additional objectives are to describe seasonal trends and address spatial variability in the data. This report presents the lake monitoring data for the calendar year 2007 ACTIVITIES AND METHODS Regular monthly lake sampling was conducted at seven locations in Lake Norman and one location each on Lake Cornelius and Lake Davidson (Appendix A), ten locations in Mountain Island Lake (Appendix B) and eight sampling locations in Lake Wylie (Appendix C). In May 2007, the sampling program was changed in Lake Wylie to add several new cove monitoring sites. This resulted in an increase in regular sampling sites in Lake Wylie from eight to thirteen (Appendix D). Lakes Norman, Wylie and Mountain Island were sampled monthly from May through September and every other month during the rest of the year, i.e. -
Using the Water Quality Index (WQI), and the Synthetic Pollution Index
Sains Malaysiana 49(10)(2020): 2383-2401 http://dx.doi.org/10.17576/jsm-2020-4910-05 Using the Water Quality Index (WQI), and the Synthetic Pollution Index (SPI) to Evaluate the Groundwater Quality for Drinking Purpose in Hailun, China (Penggunaan Indeks Kualiti Air (WQI) dan Indeks Pencemaran Sintetik (SPI) untuk Menilai Kualiti Air Bawah Tanah untuk Tujuan Minuman di Hailun, China) TIAN HUI*, DU JIZHONG, SUN QIFA, LIU QIANG, KANG ZHUANG & JIN HONGTAO ABSTRACT Due to the impact of human agricultural production, climate and environmental changes. The applicability of groundwater for drinking purposes has attracted widespread attention. In order to quantify the hydrochemical characteristics of groundwater in Hailun and evaluate its suitability for assessing water for drinking purposes, 77 shallow groundwater samples and 57 deep groundwater samples were collected and analyzed. The results show that deep groundwater in - aquifers in the study area is weakly alkaline, while that in shallow is acidic. The abundance is in the order HCO3 > - 2- 2+ + 2+ Cl > SO4 for anions, and Ca > Na > Mg for cations. Groundwater chemical type were dominated by HCO3-Ca, HCO3-Ca• Mg, and HCO3-Ca• Na. Correlation analysis (CA) and Durov diagram showed that rock weathering and dissolution, human activities, and the hydraulic connection between shallow and deep water are the main reasons affecting the chemical composition of water in Helen. The analysis of water samples based on the WQI model showed that about 23.37, 23.37, 32.46, 12.98, and 7.79% of the shallow groundwater samples were excellent, good, poor, very poor, and unsuitable for drinking purposes, respectively, and that 61.40, 30.90, 5.26, 1.75, and 1.75% of the deep groundwater samples were excellent, good, poor, very poor, and unsuitable for drinking purposes, respectively. -

Controlling Groundwater Pollution from Petroleum Products Leaks
Environmental Toxicology III 91 Controlling groundwater pollution from petroleum products leaks M. S. Al-Suwaiyan Civil Engineering Department, King Fahd University of Petroleum and Minerals, Saudi Arabia Abstract Groundwater is the main source of potable water in many communities. This source is susceptible to pollution by toxic organic compounds resulting from the accidental release of petroleum products. A petroleum product like gasoline is a mixture of many organic compounds that are toxic at different degrees to humans. These various compounds have different characteristics that influence the spread and distribution of plumes of the various dissolved toxins. A compositional model utilizing properties of organics and soil was developed and used to study the concentration of benzene, toluene and xylene (BTX) in leachate from a hypothetical site contaminated by BTX. Modeling indicated the high and variable concentration of contaminants in leachate and its action as a continuous source of groundwater pollution. In a recent study, the status of underground fuel storage tanks in eastern Saudi Arabia and the potential for petroleum leaks was evaluated indicating the high potential for aquifer pollution. As a result of such discussion, it is concluded that more effort should be directed to promote leak prevention through developing proper design regulations and installation guidelines for new and existing service stations. Keywords: groundwater pollution, petroleum products, dissolved contaminants, modelling contaminant transport. 1 Introduction Water covers about 73% of our planet with a huge volume of 1.4 billion cubic kilometers most of which is saline. According to the water encyclopedia [1], only about 3-4% of the total water is fresh. -

PUBLICATION 8084 FWQP REFERENCE SHEET 11.2 Reference: Groundwater Quality and Groundwater Pollution THOMAS HARTER is UC Cooperative Extension Hydrogeology Specialist, University of California, Davis, and Kearney Agricultural Center. roundwater quality comprises the physical, chemical, and biological qualities of UNIVERSITY OF G ground water. Temperature, turbidity, color, taste, and odor make up the list of physi- CALIFORNIA cal water quality parameters. Since most ground water is colorless, odorless, and Division of Agriculture without specific taste, we are typically most concerned with its chemical and biologi- and Natural Resources cal qualities. Although spring water or groundwater products are often sold as “pure,” http://anrcatalog.ucdavis.edu their water quality is different from that of pure water. In partnership with Naturally, ground water contains mineral ions. These ions slowly dissolve from soil particles, sediments, and rocks as the water travels along mineral surfaces in the pores or fractures of the unsaturated zone and the aquifer. They are referred to as dis- solved solids. Some dissolved solids may have originated in the precipitation water or river water that recharges the aquifer. A list of the dissolved solids in any water is long, but it can be divided into three groups: major constituents, minor constituents, and trace elements (Table 1). The http://www.nrcs.usda.gov total mass of dissolved constituents is referred to as the total dissolved solids (TDS) concentration. In water, all of the dissolved solids are either positively charged ions Farm Water (cations) or negatively charged ions (anions). The total negative charge of the anions always equals the total positive charge of the cations. -
