A Public Health Legal Guide to Safe Drinking Water
A Public Health Legal Guide to Safe Drinking Water Prepared by Alisha Duggal, Shannon Frede, and Taylor Kasky, student attorneys in the Public Health Law Clinic at the University of Maryland Carey School of Law, under the supervision of Professors Kathleen Hoke and William Piermattei. Generous funding provided by the Partnership for Public Health Law, comprised of the American Public Health Association, Association of State and Territorial Health Officials, National Association of County & City Health Officials, and the National Association of Local Boards of Health August 2015 THE PROBLEM: DRINKING WATER CONTAMINATION Clean drinking water is essential to public health. Contaminated water is a grave health risk and, despite great progress over the past 40 years, continues to threaten U.S. communities’ health and quality of life. Our water resources still lack basic protections, making them vulnerable to pollution from fracking, farm runoff, industrial discharges and neglected water infrastructure. In the U.S., treatment and distribution of safe drinking water has all but eliminated diseases such as cholera, typhoid fever, dysentery and hepatitis A that continue to plague many parts of the world. However, despite these successes, an estimated 19.5 million Americans fall ill each year from drinking water contaminated with parasites, bacteria or viruses. In recent years, 40 percent of the nation’s community water systems violated the Safe Drinking Water Act at least once.1 Those violations ranged from failing to maintain proper paperwork to allowing carcinogens into tap water. Approximately 23 million people received drinking water from municipal systems that violated at least one health-based standard.2 In some cases, these violations can cause sickness quickly; in others, pollutants such as inorganic toxins and heavy metals can accumulate in the body for years or decades before contributing to serious health problems. -
Water Quality Monitoring
Intermediate Student Guide to Water Quality Monitoring Developed in cooperation with the Texas Stream Team. Guadalupe-Blanco River Authority flowing solutions Monitoring Manual Intermediate School Level Introduction to Student Field Guide The Guadalupe-Blanco River Authority and Texas Stream Team encourages ordinary folks to be curious about how clean the water is in their creeks, rivers, and ponds. The program teaches citizens how to spot problems in water quality. Before we get started, we should discuss the term “water quality”. When we observe a water body like a creek or river, we look at the condition of the water – does it appear clear? Does it have a smell? Is the water moving, or is it still? Answering these types of questions tell us about the quality of the water. Did you ever stop to think about water as being healthy or non-healthy? Sure you did! Just think about it…. You’ve likely seen nice clean streams or rivers…. These are examples of ‘good’ water quality. You may have also observed water that is not too appealing…or ‘poor’ water quality. When you make these simple observations, you are judging the health of the water. Ok, we’ve made it pretty clear -- when we are involved in water quality studies, we are determining the health of a body of water. This guide will assist you in learning how to identify if there are any problems in water quality. You will work with a nearby creek, river, or lake – your teacher will decide what your study area will be. You will learn how to conduct simple tests. -
Standard Methods for the Examination of Water and Wastewater
Standard Methods for the Examination of Water and Wastewater Part 1000 INTRODUCTION 1010 INTRODUCTION 1010 A. Scope and Application of Methods The procedures described in these standards are intended for the examination of waters of a wide range of quality, including water suitable for domestic or industrial supplies, surface water, ground water, cooling or circulating water, boiler water, boiler feed water, treated and untreated municipal or industrial wastewater, and saline water. The unity of the fields of water supply, receiving water quality, and wastewater treatment and disposal is recognized by presenting methods of analysis for each constituent in a single section for all types of waters. An effort has been made to present methods that apply generally. Where alternative methods are necessary for samples of different composition, the basis for selecting the most appropriate method is presented as clearly as possible. However, samples with extreme concentrations or otherwise unusual compositions or characteristics may present difficulties that preclude the direct use of these methods. Hence, some modification of a procedure may be necessary in specific instances. Whenever a procedure is modified, the analyst should state plainly the nature of modification in the report of results. Certain procedures are intended for use with sludges and sediments. Here again, the effort has been to present methods of the widest possible application, but when chemical sludges or slurries or other samples of highly unusual composition are encountered, the methods of this manual may require modification or may be inappropriate. Most of the methods included here have been endorsed by regulatory agencies. Procedural modification without formal approval may be unacceptable to a regulatory body. -

In these cases, a necessary first step toward solving household water parts per billion (ppb) is used. Some contaminants have quality** problems. Before seeking testing, you may units that are specific to the test like those used forradon , have had concerns about the safety of the water used in hardness, conductance, and turbidity. Others, such as the household. Or you may have noticed objectionable pH, are expressed as an index number and not in terms of symptoms when using the water for drinking, cooking, concentration, and therefore have no units. or other household purposes. Perhaps you have routinely Even with modern techniques and expensive equipment, monitored your household water quality through periodic there are limits to which a water testing laboratory may testing and have recently noticed differing results between determine the amount of a given contaminant in water.

Laboratory Equipment Used in Filtration
KNOW YOUR LAB EQUIPMENTS Test tube A test tube, also known as a sample tube, is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top and closed at the bottom. Beakers Beakers are used as containers. They are available in a variety of sizes. Although they often possess volume markings, these are only rough estimates of the liquid volume. The markings are not necessarily accurate. Erlenmeyer flask Erlenmeyer flasks are often used as reaction vessels, particularly in titrations. As with beakers, the volume markings should not be considered accurate. Volumetric flask Volumetric flasks are used to measure and store solutions with a high degree of accuracy. These flasks generally possess a marking near the top that indicates the level at which the volume of the liquid is equal to the volume written on the outside of the flask. These devices are often used when solutions containing dissolved solids of known concentration are needed. Graduated cylinder Graduated cylinders are used to transfer liquids with a moderate degree of accuracy. Pipette Pipettes are used for transferring liquids with a fixed volume and quantity of liquid must be known to a high degree of accuracy. Graduated pipette These Pipettes are calibrated in the factory to release the desired quantity of liquid. Disposable pipette Disposable transfer. These Pipettes are made of plastic and are useful for transferring liquids dropwise. Burette Burettes are devices used typically in analytical, quantitative chemistry applications for measuring liquid solution. Differing from a pipette since the sample quantity delivered is changeable, graduated Burettes are used heavily in titration experiments. -
