In Watsr, after a four-year review of the bottled-water industry and its Wateer standards, NRDC concluded that there is no assurance that bottled is cleaner or safer than tap water. In fact, an estimated 25 percent or more of water sold in a plastic bottle is really just tap water in a bottle—sometimes further treated, sometimes not.
Of the 1, bottles tested, the majority proved to be relatively clean and pure. About 22 percent of the brands tested contained chemicals at levels above state health limits in at least one sample. If consumed over a long period of time, some of those contaminants could cause cancer or other health problems for people with weakened immune systems.
Though it's mostly safe, tap might at times also present issues—especially if you live in a rural community with a higher likelihood of pesticide runoff contamination, or if you get your water from a private unregulated well or live in an older home.
Under "right-to-know" provisions in the drinking water law, all tap suppliers must provide annual quality reports to their customers. You also can test your water yourself. Standard consumer test packages are available through large commercial labs at a relatively reasonable price.
Call your state drinking-water program or the EPA Safe Drinking Water Hotline for a list of contacts. Your water report will point out possible risks to health; fortunately, a home filter designed explicitly to strip contaminants will resolve most cases.
If you want to take extra precautions, you should purchase filters certified by NSF International. These models are designed to filter out specific contaminants, so you can select one based on your needs.
Even though both the federal government and most states have bottled-water safety programs, regulations don't adequately assure consumers of either purity or safety.
A few state programs for example, those in Massachusetts and New York maintain lists of the sources, but not all do. Carefully check the label and even the cap; if it says "from a municipal source" or "from a community water system," this means it's derived from tap. If you don't find any information on the bottle, you can call the bottler or the program in your state or the state where it was packaged and ask about the source.
Recent research suggests there might be cause for concern. Chemicals called phthalateswhich are known to disrupt testosterone and other hormones, can leach from the container into the water over time.
One study found that water that had been stored for 10 weeks in plastic and in glass bottles containing phthalates, suggesting that the chemicals could be coming from the plastic cap or liner.
Although there are regulatory standards limiting phthalates in tap, there are no legal limits in bottled water; the industry waged a successful campaign opposing the FDA proposal to set a legal limit for these chemicals.

: Water vs| Hard Water vs. Soft Water: What's the Difference and Does It Matter? | Tap water is water that is supplied through a water dispenser valve and is derived from a public water system. Public water systems PWSs are municipal bodies that are responsible for regulating, operating, and maintaining treatment plants or water sources that supply drinking water distribution systems. The development and spread of tap water systems over the past century has transformed the world by making clean water available to billions of people who would otherwise have continued to suffer all the health and development problems caused by clean water scarcity of centuries past. Public tap water types with definitions and examples can be found below. The organization of public water systems varies throughout the world. The EPA recognizes three categories of public water systems:. In there were approximately , public water systems in the United States, according to EPA drinking and groundwater statistics. Of which, 52, Sources for public water systems are both ground and surface water. In the European Union, fixed public or private water supplies are regulated by the Drinking Water Directive DWD. In addition to the main difference of choice and source as mentioned above, an additional difference that warrants a mention is the distribution system. This chain of responsibility and possibility of external contamination is absent with bottled water, as the process is controlled from the source through the bottling by the sole manufacturer. This of course may vary in different places around the world, but on average it is true. The main advantage of tap water throughout the world is its low cost. Tap water costs a fraction of a penny per gallon. The main disadvantage of tap water is the requirement of well-developed infrastructure for ensuring its adequate regulation, maintenance, and contamination prevention. The maintenance of a safe tap water system requires a well-oiled regulatory organization that sets and enforces standards. Unfortunately, the governmental infrastructure for this type of organization is weak in many developing countries which partly explains why there is a lack of access to safe tap water in many developing countries. This video from PBS NewsHour examines the problems Cape Town, South Africa has faced maintaining adequate water infrastructure. Furthermore, tap water is more exposed to contamination. The sources of public water systems are often surface waters such as rivers, lakes, or reservoirs that are fed through tributaries. These surface waters can be exposed to significant environmental pollution which bottled water generally has less exposure to. Additionally, the pipe networks that are the foundation of tap water systems are often old or otherwise at risk of intrusion of contaminants. For example, environmental and sewage intrusion from the outside of the pipe to the inside as well as heavy metals leaking from old copper pipes can all cause contamination of tap water. The differences between bottled and tap water include the cost, degree of environmental impact, and regulatory differences. The price differential between bottled and tap water is an important consideration. Compared to tap water, bottled water has a higher environmental footprint in most usage scenarios. For example, to meet America's demand for bottled water, an estimated 28 million barrels of oil are required annually. This contributes to the use of fossil fuels and hence global warming. Often, organizations that regulate standards for tap and bottled water are different. Although much effort has been made to eliminate differences in regulatory standards for these two types of drinking water, variability still exists in certain health and safety standards. There is no inherent health difference between tap and bottled water as categories. However, the individual mineral and pollutant content of the specific tap water or bottled water available in your area will determine if your tap water is healthier than the bottled waters you have to choose from or vice versa. The following are the issues to examine locally to determine which is healthier. Two scenarios where bottled water is always healthier are 1 emergency situations after natural disasters where local tap water has been contaminated and treatment plants are not operational. Such as following Hurricane Katrina in Louisiana in And 2 when local tap water systems have degraded to the point where treatment plants and distribution systems can no longer clean out sewage and contaminants, such as in the Gaza Strip today. In these types of situations, bottled water or water brought in on tankers is the only healthy solution. Tap and bottled water are generally equally safe thanks to strict regulations and enforcement for both in developed countries. In developing countries, bottled water is often - though not always - safer because of less developed and poorly maintained and regulated tap water systems. Though there is great variability country to country and bottled water producers in these countries sometimes engage in unsafe practices as well. Concerns with tap water safety often deal with contamination from chemicals, pathogens, and heavy metals which contributes significantly to the global burden of disease. Even in developed countries, rural communities where infrastructure may not be as well developed or where agricultural runoff is significant can face such issues. Furthermore, the safety of tap water can become compromised during catastrophic events, such as severe flooding, or when public water systems are improperly monitored and treated as seen in Flint, Michigan. The US Centers for Disease Control CDC has reviewed systems around the world and found that with only a few local exceptions, the following countries have safe tap water. The factors that contribute to the safety of tap water are outlined in this explainer video from TED-Ed. Bottled water is also generally safe, but has a few positive and negative differences in safety concerns:. Municipal tap water has a much lower environmental impact than bottled water, although many bottled water companies are working to be environmentally net positive. The volume of bottled water consumption has been steadily growing since , and in was estimated by the Beverage Marketing Corporation to be billion gallons billion liters. An environmental assessment of the impacts of bottled water carried out by Dr. The non-profit organization Green America lists the following items as some of the key environmental impacts of bottled water. Municipal tap water must be treated by processes such as coagulation, flocculation, sedimentation, filtration, and disinfection. All of these processes require energy inputs and chemicals aluminum sulfate, aluminum chloride, sodium aluminate, ferrous sulfate, ferric sulfate, ferric chloride, etc. to ensure the safety of tap water. At the same time, bottled water companies are working hard to become environmentally positive. Tap water remains the winner by far in terms of lower environmental impact for water, but bottled water is one of the most environmentally friendly packaged beverages and is making efforts to become greener. For daily drinking, tap water is best. But if one is going to have a packaged beverage on the go, bottled water is the greenest versus other drinks. This is probably an underestimate of the average bottled water price and overestimate of tap water. There are more premium water brands every year and more of them are served at ever higher prices in restaurants. And Harvard is likely over-estimating the average price of tap water. On the tap side, the Harvard data appears higher than the US national average. But Phoenix was a mere 0. Boston was fairly typical of the middle of the pack at 1. In areas with safe tap water, there is no price reason to ever drink bottled water merely for regular hydration. It is only justified if it fulfills other needs of the consumer for which it might be more competitive. Many countries have different regulations and regulatory agencies for tap water versus bottled water, but both sides are generally regulated enough to ensure high-quality, safe water. The root of the different regulatory frameworks in most countries is the mix of international, national, regional, and local agencies that have different reasons for creating standards. Bottled water is regulated by the Food and Drug administration because it is a packaged food product. Despite the federally insured similarity between EPA and FDA regulation, differences still exist. The key regulation differences between tap and bottled water in the United States include the following. This table from the US Safe Drinking Water Foundation SDWF summarizes some of the differences between US tap water and bottled water regulations. It highlights how the relative strictness varies depending on the metric being tested. Additionally, to cut down on plastic pollution, we would always recommend opting for water that comes in glass bottles when possible. To check the quality of your local tap water, check with the EPA.

| Is Bottled Water Healthier Than Tap Water? | University Hospitals | ECO-FRIENDLY WATER COOLERS. VIEW WATER COOLERS. Quench Water Experts. Purified Water Purified water, typically made with groundwater or tap water, goes through a filtration process to remove various impurities and contaminants. Public drinking water goes through standard water filtration, comprised of the following treatment methods: Coagulation: Positively charged chemicals are added to the water supply to neutralize the negative charge of dirt and other dissolved particles. Flocculation: The water source is mixed to form larger, heavier particles called flocs. Sedimentation: Flocs settle to the bottom, separating solids from the water. Filtration: The clean water that was isolated by sedimentation and left on the top is filtered again to separate additional solids from the water. Disinfection: One or more chemical disinfectants, such as chlorine or chlorine dioxide, can be added to the filtered water to kill any remaining contaminants or bacteria. Boiling water: Simply boiling water is a valid way to kill disease-causing germs , including viruses, bacteria, and parasites, as reported by the CDC. Reverse osmosis RO : To make reverse osmosis water, harmful contaminants and other impurities are removed by using pressure to force water molecules through a semipermeable membrane. Distilled Water Distilled water, on the other hand, is a type of purified water that goes through the distillation process to remove impurities and other water contaminants. Purdue University reports that this water purification system is highly effective at removing impurities like: A wide range of bacteria and viruses. Protozoa like giardia. Harmful chemicals such as sulfate and lead. Various purification methods ultimately promote several valuable benefits: Purification successfully removes bacteria that can lead to adverse health effects e. Systems for purification like charcoal filters remove chlorine, a common chemical added to the public water supply as a disinfectant and linked to a higher risk of certain cancers. Filtration removes unpleasant tastes associated with organic matter, chemical treatments, or metal plumbing. Drinking purified water supports a healthier colon and digestive tract. Most purification systems improve the cleanliness of tap water, especially in areas with lower water quality. Opting for bottled water to gain access to pure water is costly and unsustainable. Certain purification systems remove the fluoride in tap water , which is known to reduce tooth decay and support overall dental health. Some filtration and purification systems require maintenance and upkeep to ensure the water filter maintains effectiveness over time. Consider the following benefits: Distillation is a particularly impressive technique to remove contaminants from water. Because of a lack of impurities like bacteria and pesticides, distilled water is beneficial for individuals with weakened immune systems e. Distilling water effectively removes chlorine from the water, which boosts its taste. While being free from contaminants, this type of water also lacks electrolytes and natural, healthy minerals — like magnesium and calcium — which are important for your health. Which Option Is Best?

UnityPoint Health News and Articles Water vs. When to Consume Sports and Electrolyte Drinks Sports and electrolyte drinks often seem like the perfect way to quench your thirst when working out, but according to Dr. Benefits of Sports Drinks Carbohydrates. Nish says fluid containing carbohydrates can be consumed at 30 to 60 grams per hour. He says most sports drinks will provide two to 19 grams of carbohydrate per eight ounces. Carbohydrates come in the form of sugars or polymerized glucose. All sports drinks contain some sodium, usually between 35 and mg per eight ounces. Sodium helps the body retain water. Most sports drinks also have between 15 and 90 mg of potassium per eight ounces. However, Dr. Nish suggests choosing a drink higher in sodium, if you are participating in prolonged endurance events or are heavily sweating. Amino acids. Some sports drinks also contain amino acids, which are said to enhance muscle recovery. Nish says most children and adults eating a well-balanced diet do not need this additive. Why Sports Drinks Can Be Unhealthy Sports drinks were designed for those performing intense physical activity. For the average person, these offer no advantages and many contain lots of sugar. In fact, Dr. Nish says some have up to eight teaspoons per serving. As far as the vitamins, Dr. Nish says most people should be getting all they need from a diet rich in vegetables, fruits and nuts. Coconut water. Nish says coconut water has very low levels of carbohydrates, as well as small amounts of sodium and potassium. |
