The New York Times reported 12/17/09 that federal law regulating tap water is so out of date that our water can pose serious health risks in an article viagra “Tap water is legal but may be unhealthy”. Does it make sense to continue to drink tap water, risking your health, waiting for politicians and special interest groups to conclude that it is just too expensive anyway for most city water users to afford? And what about well water users? They don’t even get EPA required testing. The answer is quite simple and inexpensive also. Tap water is usually acceptable for most household uses. It is only necessary to do something with the water you will consume (only about 1% of your total water usage). The simplest, most effective product to remove up to 99% of most known, and future, natural and manmade contaminants is reverse osmosis drinking water purification. This process is recommended by the EPA and is also the most common technology used by drinking water manufacturers. This tri stage filter system can be easily installed under your kitchen sink to provide pure water for drinking and cooking, and also provide water for your refrigerator ice maker, all at a cost of less than .10 cents per gallon. You’ll never care nor worry about where your tap water comes from or what is in it again.

“NEW YORK —Regulatory and water system data analyzed by The New York Times show that more than 49 million people in the US have consumed polluted drinking water since 2004, according to a report in the December 8 print edition of The New York Times.

Pollutants of concern included concentrations of chemicals like arsenic or radioactive substances like uranium, as well as bacteria often found in sewage, the report said.

Analyzing data from the US Environmental Protection Agency (EPA) and other regulators and water systems, the New York Times reported: “More than 20 percent of the nation’s water treatment systems have violated key provisions of the Safe Drinking Water Act over the last five years, according to a New York Times analysis of federal data.”

Fewer than 6 percent of the water systems that broke the law were ever fined or punished by state or federal officials. According to the article, which quoted current and former EPA enforcement officials who wished to remain anonymous, federal regulators were informed of violations, but in many cases, unless the violations would make sensational news stories or target big money, pursuing the violations were overlooked.

EPA spokeswoman Adora Andy, in response to questions regarding the agency’s drinking water enforcement, told the New York Times: “This administration has made it clear that clean water is a top priority. The previous eight years provide a perfect example of what happens when political leadership fails to act to protect our health and the environment.”

In response to the article, Water Quality Association (WQA) Executive Director Peter J. Censky said in a December 8 association statement, “Filtering systems in the home provide the highest technology available to treat drinking water. Home filtering systems act as a final contaminant barrier and can further purify water for drinking.” WQA is urging the public to consider installing home treatment systems.”

The article also noted that drinking water contaminants “are linked to millions of instances of illness within the United States each year.”

“TAMPA – The tap water that Tampa residents consume is contaminated with low levels of antibiotics, nicotine byproducts and a chemical used to produce firefighting foams.

City and state officials say the levels of the contaminants – found in recent tests of the city’s drinking water system – are miniscule and that the city’s water is safe to drink.

But the presence of the contaminants raises questions about what is coming out of the faucets in tens of thousands of households served by the city’s water system.

State and federal environmental regulators say they know little about possible health risks from the cocktail of contaminants that in recent years have been found in water supplies across the country. They are only beginning to study the long-term effects.

Without any regulation of these types of contaminants, the city isn’t required to report the findings of the recent tests to state and local environmental regulators, or the public.

Elias Franco, distribution division manager for Tampa’s water department, said the city began voluntarily testing its water for pharmaceutical contaminants two years ago.

He said the contaminants found in tests conducted in May 2009 include the antibiotic drug sulfamethoxzole; cotinine, a nicotine byproduct; and perfluorooctane sulphonate, a chemical commonly used for metal plating, photography and firefighting foams.

The contaminants were found in samples of treated drinking water taken from the city’s treatment plant, indicating that the existing filtration process doesn’t remove them.

Franco said the city meets all federal and state regulations for drinking water quality and, for now, doesn’t intend to make any wholesale changes to the water treatment system.

“The industry continues to evaluate the latest technologies available that could prove reliable in evaluating the effects of these contaminants,” Franco said in a statement, “and the City of Tampa will continue to stay abreast of these developments.”

Neither the state nor federal government requires testing for unregulated contaminants such as those found in Tampa’s drinking water and regulators haven’t set safety limits.

Only one of the contaminants found in Tampa’s drinking water, perfluorooctane sulphonate, is regulated by federal heath officials. Even then, a health advisory is required to be issued only when the contamination levels exceed 200 micrograms per liter. The level of the chemical found in the city’s drinking water system was only 1.4 micrograms per liter.

“At this time, no research has shown that concentrations of these substances reported in recent studies pose a threat to drinking water supplies,” Dee Ann Miller, a spokeswoman for the Florida Department of Environmental Protection. “Research is ongoing, especially on the effects of multiple chemical constituents at low concentrations.”

How does it get into the water?

Tampa officials attribute the contaminants found in the recent tests to pollution from the Hillsborough River, the city’s primary source of drinking water.

When people take medicine or smoke, some of the chemicals are absorbed by the body, but the leftovers end up getting flushed down the toilet and into the water supply.

The wastewater is treated before it is discharged into reservoirs, rivers or lakes.

Leaking septic tanks also can eventually send contaminants into drinking water systems, and regulators say pharmaceuticals can also permeate aquifers deep underground, a source of about 90 percent of the state’s drinking water supplies.

State environmental regulators say despite the recent emphasis on pharmaceuticals in the drinking water supplies, it’s likely people have been consuming them for a long time.

“It is inevitable that small amounts of these compounds will be released to the environment,” the DEP’s Miller said. “It is also likely that these compounds have been there for decades and have remained undetected until the recent development of analytical methods to enable their identification and quantification.”

And Tampa is not alone.

Two years ago, an Associated Press investigation revealed how scientists have found that water piped to millions of people nationwide contains minute concentrations of contaminants ranging from tranquilizers to painkillers to antibiotics.

While scientists have not established that people are harmed by these drugs, the AP reported, laboratory tests conducted by research teams at universities in the U.S. and Europe have shown that tiny amounts can have ill effects on human cells, especially when ingested over decades, possibly in combination with other drugs or in sensitive populations such as children and pregnant women.

Since the AP report stirred congressional hearings and legislation, the U.S. Environmental Protection Agency has launched a survey to check for 200 chemical and microbial contaminants at 50 water treatment plants across the nation, and health agencies are conducting research to clarify how humans might be harmed by drugs at low environmental levels.

This research will help federal officials decide whether regulations are needed.

Locally, few local governments test for pharmaceuticals on their own, relying instead on Tampa Bay Water, which provides water to Hillsborough, Pinellas and Pasco counties.

From 2002 to 2005, the U.S. Geological Survey tested groundwater supplied by Tampa Bay Water to its members for pharmaceuticals and other contaminants, but didn’t find anything, according to Chris Owen, the authority’s water quality assurance officer.

Hillsborough County has for several years tested for herbicides and other unregulated contaminants under an agreement with the EPA, but not for antibiotics, steroids, growth hormones and other pharmaceuticals that have been detected in other water systems.

“Even if we found something, we don’t yet know what the health risks are from these types of contaminants,” said Luke Mulford, Hillsborough’s water quality engineer.

“And it’s going to be a long time before we know.”

Contaminants in drinking water

Recent tests of Tampa drinking water system found the following contaminants:

Sulfamethoxzole: An antibiotic used to treat bacterial infections. Level found in recent tests: 1.1 nanogram per liter ng/L

Cotinine: Created by the breakdown of Nicotine in the human body. Level found in recent tests: 2.3 nanogram per liter ng/L

Perfluorooctane Sulphonate: Used to produce fire fighting foams and coatings for fabrics, leather, and some paper products, this chemical is known to persist in the environment and to accumulate in human and animal tissues. Level found in recent tests: 1.4 nanogram per liter ng/L”

That law requires communities to deliver safe tap water to local residents. But since 2004, the water provided to more than 49 million people has contained illegal concentrations of chemicals like arsenic or radioactive substances like uranium, as well as dangerous bacteria often found in sewage.

Routine sampling was conducted on June 9th as part of the Inland Lakes Program, which helps the agency determine if the water meets standards for drinking water, fishing, recreation, and wildlife habitat. The additional samples will be used in tests for pesticides, such as DDT.

Although testing can take as long as two years, the OEPA is hoping to have the results delivered sometime next year.

In an analysis of more than 22 million tap water quality tests, most of which were required under the federal Safe Drinking Water Act, EWG found that water suppliers across the U.S. detected 260 contaminants in water served to the public. One hundred forty-one (141) of these detected chemicals — more than half — are unregulated; public health officials have not set safety standards for these chemicals, even though millions drink them every day.

“It is vital for public policy makers to understand what tens of millions of Americans are ingesting and how they can be helped,” said Peter Censky, president of WQA.

Nearly 45 million people rely on private wells for drinking water, which is not regulated by the federal Safe Drinking Water Act. According to news reports in previous months, almost one in six Americans may be affected by pharmaceuticals in their household water. Additionally, many other contaminants are often present, either from natural or human sources.
