How much water does the average person use at home per day?

USGS


Estimates vary, but each person uses about 80-100 gallons of water per day. Are you surprised that the largest use of household water is to flush the toilet, and after that, to take showers and baths? That is why, in these days of water conservation, we are starting to see toilets and showers that use less water than before.

Many local governments now have laws that specify that water faucets, toilets, and showers only allow a certain amount of water flow per minute. Water agencies in some areas, such as here in Atlanta, Georgia, offer rebates if you install a water-efficient toilet. In fact, I just put in two new toilets and received a rebate of $100 for each. Yes, they really do use a lot less water. For your kitchen and bathroom faucets, if you look real close at the head of a faucet, you might see something like “1.0 gpm”, which means that the faucet head will allow water to flow at a maximum of 1.0 gallons per minute.

Typical water use at home
Bath A full tub is about 36 gallons.
Shower 2 gallons per minute. Old shower heads use as much as 5 gallons per minute.
Teeth brushing <1 gallon, especially if water is turned off while brushing. Newer bath faucets use about 1 gallon per minute, whereas older models use over 2 gallons.
Hands/face washing 1 gallon
Face/leg shaving 1 gallon
Dishwasher 4 to 10 gallons/load, depending of efficiency of dishwasher
Dishwashing by hand: 20 gallons. Newer kitchen faucets use about 2.2 gallons per minutes, whereas older faucets use more.
Clothes washer 25 gallons/load for newer washers. Older models use about 40 gallons per load.
Toilet flush 3 gallons. Most all new toilets use 1.6 gallons per flush, but many older toilets used about 4 gallons.
Glasses of water drunk 8 oz. per glass (did you remember to drink your 8 glasses of water today?)
Outdoor watering 5 to 10 gallons per minute

Water Treatment Systems and Air Purification by RainSoft

The Importance of Water Treatment in the Home

The benefits of home water treatment come in many forms. Whether you’re a mom bringing your new bundle of joy home, or a family looking for solutions to hard water, home water filtration systems from RainSoft offer your family the perfect solution to any home water concern. And with water conditioning and softening systems from RainSoft, you get the benefit of quality products, most with a limited lifetime warranty, which require little maintenance and are energy efficient.

While most communities’ water supplies meet EPA Primary Drinking Water Standards, from source to your tap, water can still pick up impurities and contaminants not controlled by your city’s water supplier. Unwanted chemicals, minerals and other pollutants can accumulate as water travels your pipes, leaving you with odors and bad tastes. Identifying these problems can sometimes be easy; noticeable odor, visible particles, metallic or other bad tastes certainly are causes for concern. But other times the problems are not so readily apparent.

The solution to these concerns? Simple: RainSoft. With dedicated laboratory, manufacturing, research and development facilities and thorough third party testing, we strive to produce premium home water filtration systems that are dependable and reliable. From better tasting drinking water, cleaner washing and cooking water and softer, more refreshing bathing water, the advantages of installing RainSoft home water filtration systems can be seen in almost every room in the house.

The Myth of Sports Drinks and Exercise

Myth buster: Sports drinks vs. water

 Published 4:59 p.m., Tuesday, October 16, 2012 | SFGate

Myth: Sports drinks keep you better hydrated than water during a workout.

Fact: Those giant sports drink coolers on the sidelines of professional sporting events send fans a strong message – your favorite athletes drink this stuff, and you should, too. But according to new research, sports drinks aren’t proved to deliver all they promise, and water is all that most people need to stay hydrated.

Americans buy $1.5 billion worth of sports drinks annually, but a series of studies in the British Medical Journal say there isn’t enough evidence to support so-called scientific claims by sports drink makers that their products optimize athletic performance and recovery. For more information: bit.ly/T9tYeu.

In one study the journal examined 104 sports drinks and other products that claim to enhance athletic performance. There were 431 claims associated with these products, and researchers found that slightly more than half of them were not backed up. Most of the study references the ads did provide were either so vague that the journal’s researchers couldn’t analyze them, or they referred to studies that the researchers said had a high risk of bias. The researchers reported that only three of the studies referenced were of “high quality and low risk of bias.”

Aside from that, there are nutritional problems with sports drinks. According to the Harvard University School of Public Health, sports drinks contain between three to 14 teaspoons of sugar and as many as 255 calories. Water has neither. And when determining how much water to drink before, during and after a workout, the Harvard team says thirst can be the guide. Source: hvrd.me/RAlnCd.

Then there’s the question of electrolytes – minerals like calcium, potassium and sodium that decrease slightly as your body sweats them out during exercise. Water doesn’t contain electrolytes; sports drinks do. Researchers at the University of North Carolina at Chapel Hill say that people who work out vigorously for an hour or more lose enough electrolytes to warrant replacing them with sports drinks. Researchers add, however, that you can also replace electrolytes with a balanced diet, including mineral-rich fruits and vegetables.

That Stomach Ache May Be Due To Leaky Pipes

Tainted Tap Water Sickens 1.1 Million Each Year

Viruses Creep Into Public Water Supplies Through Leaky Pipes

Sept. 14, 2012 – The pipes that ferry drinking water from public wells to home taps may let in viruses that cause more than a million cases of stomach illness every year, two new studies show.

“This is a really big deal,” says Jeffrey Griffiths, MD, MPH&TM, a professor at Tufts University and chair of the drinking water committee of the U.S. EPA’s science advisory board. “This research is very important.”

“Our delivery pipe system is old in many parts of the country and leaky and not being replaced,” says Griffiths, who was not involved in the studies.

Griffiths says the research “really documents that it’s possible for people to get viruses that make them sick through their drinking water.”

The studies stem from the same government-funded research project. It is one of the largest ever to look at illnesses tied to public water supplies.

“The drinking water that we have in the U.S. is very, very good relative to other countries,” says researcher Frank Loge, an environmental engineer at the University of California at Davis. “But in terms of what we expect from our drinking water, in terms of health and safety, I was alarmed,” he says.

Looking at the Safety of Public Water Supplies

The project compared 14 public water systems in Wisconsin. Like more than 147,000 towns in the U.S., all the communities in the study pumped their public water from underground pools called aquifers. And like the majority of communities that rely on groundwater, the 14 in the study didn’t disinfect the water after it left those large wells.

For the first year, eight of the communities installed powerful ultraviolet (UV) lights to clean the water as soon as it left the underground pool. The other six continued to have no disinfection.

Scientists sampled water each month from the underground pool, from an area that was just past the UV disinfection, and then from six to eight home taps. The second year, the towns swapped. The eight towns that used UV disinfection turned their systems over to the six that didn’t have them. That let scientists compare how well the UV systems worked to clean the water.

After the two years of watching the water, researchers found that no community had consistently clean or consistently contaminated water.

When they plugged their measurements into models that estimate risk, they found that nationwide, drinking water that’s tainted as it travels through pipes to people’s homes could be responsible for as many as 1.1 million cases of acute stomach illness each year. That’s a level of illness that’s 559 times higher than what the EPA considers acceptable for public drinking water supplies.

Mark A. Borchardt, PhD, a microbiologist with the USDA’s Agricultural Research Service, says that normally, the average person can expect to get sick with a stomach bug once or twice in a given year. People who drink water from public systems that aren’t disinfected can expect to see that risk climb by about 30%. Looking at the numbers another way, that means as many as 1 in 5 cases of stomach illness each year may be caused by contaminated water. That number may be as high as 2 out of 5 cases in kids.

Public Water Infrastructure Problems

Researchers were concerned about what happens to water on its way to the tap because much of the public water infrastructure in the U.S. is in a state of disrepair. In a 2009 report, the American Society of Civil Engineers gave America’s drinking water systems a D- grade and stressed the need for more money to replace crumbling facilities and plumbing.

To make matters worse, Borchardt says many pipes that carry drinking water are laid close to lines that carry untreated sewage. Like the water pipes, the sewer lines are also often not in great shape.

“If you dig up soil around drinking water pipes, you can find all sorts of pathogens that come from leaking sewer lines,” Borchardt says. Pressure changes may then suck some of those disease-causing germs into the drinking water.

Advice for Safer Tap Water

Smaller towns and rural areas are more likely than larger cities not to disinfect their water. To find out if your water is disinfected or not, contact your municipal water supplier.

If you live in a community where groundwater isn’t disinfected, Loge says there are home systems that can be installed to clean water before you drink it.

Those systems range from $100 to $500 in price and usually need to be professionally installed.

Presidential Inauguration Serving Tap Water

In response to a letter from the District of Columbia Water and Sewer Authority stating concerns about the serving of expensive bottled water vs. DC tap water at the Presidential Inaugural ceremonies, Senator Charles Schumer confirmed with his own letter that tap water would be available. He further stated that DC tap water is used every day in the offices at the Capitol as a drink choice as well as to make coffee and tea.

Tap water is an affordable alternative to expensive bottled water. The letter from DC Water further states that tap water costs about a penny per gallon compared to bottled water which costs about 100 times more.

Indoor Air Quality Impacts Your Health

Indoor Air and Your Health

From A Guide to Indoor Air Quality 
by Consumer Product Safety Commission and Environmental Protection Agency

Health effects from indoor air pollutants may be experienced soon after exposure or, possibly, years later.

Immediate effects may show up after a single exposure or repeated exposures. These include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. Such immediate effects are usually short-term and treatable. Sometimes the treatment is simply eliminating the person’s exposure to the source of the pollution, if it can be identified. Symptoms of some diseases, including asthma, hypersensitivity pneumonitis, and humidifier fever, may also show up soon after exposure to some indoor air pollutants.

The likelihood of immediate reactions to indoor air pollutants depends on several factors. Age and preexisting medical conditions are two important influences. In other cases, whether a person reacts to a pollutant depends on individual sensitivity, which varies tremendously from person to person. Some people can become sensitized to biological pollutants after repeated exposures, and it appears that some people can become sensitized to chemical pollutants as well.

Certain immediate effects are similar to those from colds or other viral diseases, so it is often difficult to determine if the symptoms are a result of exposure to indoor air pollution. For this reason, it is important to pay attention to the time and place the symptoms occur. If the symptoms fade or go away when a person is away from the home and return when the person returns, an effort should be made to identify indoor air sources that may be possible causes. Some effects may be made worse by an inadequate supply of outdoor air or from the heating, cooling, or humidity conditions prevalent in the home.

Other health effects may show up either years after exposure has occurred or only after long or repeated periods of exposure. These effects, which include some respiratory diseases, heart disease, and cancer, can be severely debilitating or fatal. It is prudent to try to improve the indoor air quality in your home even if symptoms are not noticeable. More information on potential health effects from particular indoor air pollutants is provided in the section, “A Look at Source-Specific Controls.

While pollutants commonly found in indoor air are responsible for many harmful effects, there is considerable uncertainty about what concentrations or periods of exposure are necessary to produce specific health problems. People also react very differently to exposure to indoor air pollutants. Further research is needed to better understand which health effects occur after exposure to the average pollutant concentrations found in homes and which occur from the higher concentrations that occur for short periods of time.

The health effects associated with some indoor air pollutants are summarized in the section “Reference Guide to Major Indoor Air Pollutants in the Home.”

Harvard Study Finds Fluoride Lowers IQ

Harvard Study Finds Fluoride Lowers IQ – Published in Federal Gov’t Journal

Published: Tuesday, Jul. 24, 2012 – 5:57 am

NEW YORK, July 24, 2012 – /PRNewswire-USNewswire/ — Harvard University researchers’ review of fluoride/brain studies concludes “our results support the possibility of adverse effects of fluoride exposures on children’s neurodevelopment.” It was published online July 20 inEnvironmental Health Perspectives, a US National Institute of Environmental Health Sciences’ journal (1), reports the NYS Coalition Opposed to Fluoridation, Inc. (NYSCOF)

“The children in high fluoride areas had significantly lower IQ than those who lived in low fluoride areas,” write Choi et al.

Further, the EPA says fluoride is a chemical “with substantial evidence of developmental neurotoxicity.”

Fluoride (fluosilicic acid) is added to US water supplies at approximately 1 part per million attempting to reduce tooth decay.

Water was the only fluoride source in the studies reviewed and was based on high water fluoride levels. However, they point out research by Ding (2011) suggested that low water fluoride levels had significant negative associations with children’s intelligence.

Choi et al. write, “Although fluoride may cause neurotoxicity in animal models and acute fluoride poisoning causes neurotoxicity in adults, very little is known of its effects on children’s neurodevelopment. They recommend more brain/fluoride research on children and at individual-level doses.

“It’s senseless to keep subjecting our children to this ongoing fluoridation experiment to satisfy the political agenda of special-interest groups,” says attorney Paul Beeber, NYSCOF President.  “Even if fluoridation reduced cavities, is tooth health more important than brain health? It’s time to put politics aside and stop artificial fluoridation everywhere,” says Beeber.

After reviewing fluoride toxicological data, the NRC reported in 2006, “It’s apparent that fluorides have the ability to interfere with the functions of the brain.”

Choi’s team writes, “Fluoride readily crosses the placenta. Fluoride exposure to the developing brain, which is much more susceptible to injury caused by toxicants than is the mature brain, may possibly lead to damage of a permanent nature.”

Fluoride accumulates in the body. Even low doses are harmful to babies, the thyroid, kidney patients and heavy water-drinkers. There are even doubts about fluoridation’s effectiveness (2). New York City Legislation is pending to stop fluoridation. Many communities have already stopped.

Infant formula when mixed with fluoridated water delivers 100-200 times more fluoride than breastmilk.(3)

Home Water Filters and Problem Solving

Reverse Osmosis Water Systems

It’s important for home water filtration systems to remove minerals that cause hard water and other impurities from drinking water. Homes with sodium, ferrous iron, nitrates, lead, fluoride or organic contaminants often benefit from reverse osmosis water systems, which provide premium water fit for a wonderful cup of coffee or for cooking a fine meal.

These drinking water systems filter water multiple times to ensure your good water is even better. Reverse osmosis systems differ from regular faucet-mounted systems because RO is a much more advanced method for providing pure, premium water to a dedicated faucet. Find out if sodium, ferrous iron or other organic contaminants are affecting your water’s quality with a free drinking water analysis from RainSoft.

Hard Water on the Rise with Water Demand

Excerpt form WarrenPatch | by John Patten

“Over the years there has been an increase in the hardness of the water, especially around springtime (May)—this year, there is a very noticeable difference in the water quality over the last six weeks where even the use of a water softener is unable to overcome the greatly increased hardness,” Warren resident Alice Lin Yang said in an email.

She said she contacted New Jersey American Water in late-May to check a sample of the water, and was told the hardness level of 380mg per liter of calcium carbonate (the primary cause of water hardness) is within state and federal guidelines for safe drinking water—but is a “concern.” Lin Yang said the recommended level of calcium carbonate is 250mg per liter.

New Jersey American Water spokesman Richard Barnes said water hardness is considered an “esthetics” issue, but Lin Yang notes the many problems it’s causing Warren residents.

“The hardness has been effecting the dishwashers and faucets causing a chalky residue that is difficult to remove; it has caused itchy rashes of the face and body in others,” she said, adding some have told her they replaced dishwashers because they thought something was wrong with the machine.

Lin Yang, a doctor, also said she and others she knows have been having issues with skin rashes that appeared at about the same time this spring.

“The onset of the rashes coincide with the appearance of the white residue from the water,” she said.

Barnes said the company generally draws water from surfaces sources, but when temperatures rise and demand increases, the company will supplement the water supplies by drawing on wells, which typically have higher mineral content.

“When demand is not as high, we’re able to draw from our surface sources,” Barnes said, reducing the calcium carbonate in the water.

He added residents who have water softeners in their homes should check the settings to make sure they are set for a water hardness between 350mg per liter and 400mg per liter. “That’s really the best thing to do,” he said.

Air Quality Alerts and What They Mean

Health Impact Of Air Quality Alerts

KERA news for North Texas

US EPA
Air pollution watches are common this time of year. They’ve been around since 2000, but rarely does anyone say what they mean. In a KERA Health Checkup, Robert Kent, Director of Environmental Programs for the North Texas Commission, explains the alerts are a warning about ozone in the North Texas air.

Robert Kent: Ozone is basically three oxygen molecules that have been bonded together. It’s highly reactive and unstable and so when it gets into the lungs then it ends up causing coughing, throat irritation, pain and burning in the chest and chest tightness. Additionally, if you have asthma or emphysema it can aggregate those conditions.

They’ve done some studies about what happens when we have ozone in the area and they’ll find that trips to the emergency room increase. There are more people who call in sick to work. There are more students who take absent on days when we have those. And so ozone definitely has an impact on the health of the general population.

Baker: Usually when the media gives those various levels, they just basically say, “We have an ozone alert at level orange.” But no one ever really says what that means. So what does each level represent?

Kent: So they’re color-coded on a scale so green, no problem at all. Yellow is moderate. Orange is unhealthy for sensitive groups – sensitive groups would be anyone that has respiratory problems. This would be people with asthma, emphysema, or other type of lung conditions.

Baker: So on an orange alert day, what should such people do?

Robert Kent: Individuals who are sensitive to ozone pollution should limit their outdoor activity. People who are not sensitive to ozone pollution, who don’t have asthma or emphysema or other lung conditions, they may have some effects if they are doing a lot of outdoor exertion. So if they’re working out a lot, or running, or playing basketball, they may end up feeling some of the impacts from ozone pollution on days like that.

Then you move up to red, which is unhealthy for pretty much anyone. And then you can move on to higher levels of maroon and purple, which are hazardous and very unhealthy. We haven’t had a level above red in many, many years. But this year we’ve already had one or two days that were red, and last year we had one day that was red as well.

Baker: I was just wondering, what would all of this mean for someone who is in reasonable good health? Read more…

Heart Health Affected by Ozone Air Pollution

Ozone Can Harm the Heart in as Little as Two Hours

A new study shows just how quickly exposure to air pollution can trigger dangerous changes in the heart, even in otherwise healthy young people.

By ALICE PARK | @aliceparkny | June 26, 2012 

Jarek Szymanski / Getty Images

Healthy, young volunteers with no history of heart disease showed unfavorable changes in their heart function after just two hours of exercising while being exposed to ozone, report researchers in the journal Circulation. The changes included surges in markers of inflammation, as well as drops in levels of enzymes that break down clots in the blood vessels — alterations that may explain the link between exposure to air pollution and heart risk.

The study is among the first to document the physiological changes caused by exposure to ozone, a major pollutant formed when volatile organic compounds from industrial waste or car exhaust reacts with sunlight. Previous studies have linked exposure to ozone to heart problems, but had not quantified the precise effect of the pollutant on biological markers of heart and lung function.

(MORE: Mom’s Exposure to Air Pollution Can Increase Kids’ Behavior Problems)

In the study, 23 young participants participated in two hours of intermittent exercise in a lab while being exposed first to “clean” air, and then to air containing 0.3 parts per million of ozone, which is higher than the amount found in average U.S. cities but about the peak level calculated for heavily polluted cities like Beijing, China and Mexico City. (However, the level is equivalent to the amount of ozone someone in an average American city would be exposed to over the course of seven to eight hours.) Scientists then compared readings on various biological markers of heart and lung function between the two sessions, to get a sense of ozone’s impact. Under the ozone conditions, the participants experienced a nearly 99% jump in levels of interleukin-8, an marker for inflammation in the blood vessels. They also showed a 42% drop in plasminogen levels, which lowers the body’s ability to break up blood clots. The study recorded the participants’ readings for only 24 hours after the experiment, and the changes were temporary and reversible: once the volunteers stopped breathing the heavy concentration of ozone, their measurements returned to normal levels. But the results show that ozone can have potentially harmful, and even deadly effects on the heart, say the authors. “This study provides a plausible explanation for the link between acute ozone exposure and death,” Robert Devlin, a senior scientist at the U.S. Environmental Protection Agency’s National Health and Environmental Effects Research Laboratory and the study’s lead author, said in a statement.

(MORE: Traffic Noise Linked to Heart Attack Risk)

“The results complement what are suspicions are, and help us to apply what we know about pollution risk to populations we think are at especially high risk,” says Dr. Tracy Stevens, a cardiologist at St. Luke’s Mid America Heart Institute and a spokesperson with the American Heart Association. The findings highlight the dangers of pollution to people who might already have unstable plaques in their heart vessels, she says, since ozone can trigger a surge in inflammatory markers that drive these plaques to rupture, causing a heart attack. While Stevens says the risks of pollution in aggravating inflammation are known, having data that quantifies the risk as the current study does may help more people to appreciate and address ways to reduce inflammation. The American Heart Association recommends that people with heart disease avoid going out on high-ozone days, and lower their risk of exposure to heavily polluted air, including cigarette smoke.

Stay Hydrated. You can lose 20 to 48 oz of water per hour during intense exercise.

Running in summer requires extra precautions, hydration

By Grant Gensheimer — Special to the Herald-Leader

Foot-race season is here, and many of us will take to running outside. Whether you are a seasoned runner or planning on running your first 5K this summer, there are some precautions to take to avoid heat exhaustion and heat stroke.

These occur when the body’s own temperature regulatory system becomes inadequate at keeping the body cool.

There are two mechanisms the body uses in the attempt to keep from overheating. The first is one we are all familiar with — sweating. The evaporation of sweat from the surface of the skin helps to cool the body. Only the sweat that actually evaporates from the skin has a cooling effect. All that extra fluid dripping off you during your hot summer run is essentially wasted water.

Sweat can have a hard time evaporating when the humidity level is high, making it all the more important that you take the time to adequately rehydrate.

In addition to sweating, the body will also increase blood flow to the skin in the attempt to lose some of the extra body heat to the cooler environment. While this can help in the cooling process, it has the unfortunate side effect of reducing some of the blood flow to the working muscles. That’s why your two-mile jog that may have been easy in May might become much more difficult in the heat of July or August.

When the temperature outside is higher than that of the body, this method of cooling becomes much less effective. Seek a cooler, shaded area a few times throughout your workout, and try to run in the morning or late afternoon to avoid the hottest part of the day.

When starting a running program, or doing any type of physical activity outside remember these tips in order to stay cool and safe:

■ Give yourself time to get acclimated to the summer heat. Start off running in short, easy bouts and slowly progress. It usually takes around a week of daily exposure for the body to make the necessary adaptations.

■ Stay hydrated. The body can lose anywhere between 20 and 48 ounces of water per hour during intense exercise.

■ Take frequent breaks in a cool, shaded area.

■ For intensive and/or hot training sessions lasting more than an hour consider drinking fluids with electrolytes such as a sports drink.
