How to Detect Water Contamination New Approach

“How to Detect Water Contamination In-Situ?
Scientists from Tomsk Polytechnic University have developed a device for the rapid analysis of liquids on the content of hazardous substances such as heavy metals. Polytechnicers use a method based on polymer optodes—very small plastic matrices that can be made sensitive to specific substances by means of special reagents. The matrices change color and intensity depending on the concentration of the substance. The device is mobile, can carry out analysis in situ even at low temperatures, and its cost is many times less than the price of a spectrophotometer—the most frequently used device for chemical analysis. The device is based on polymethacrylate sensors—transparent pieces of plastic with thickness of 1 mm and a size of 3×3 mm. The pores of matrices serve as receptacles, where various chemical reactions can undergo.
If a matrix is handled with a special reagent it becomes an optode sensitive to a particular substance. The researchers plunge this optode into the water to test it or simply drip a few drops on it, and it changes its color. Hence, there is a required element. Sergey Muravyov, the scientific supervisor of the project, head of the TPU International Laboratory Advanced Measurements, says: “The more intense the color is, the higher is the concentration of the substance.”

For example, if water contains silver optode, it turns purple-red. According to the scientist, the method can detect substances even at very low concentrations in water.
“You dip optode into the water and then load it into the device analyzer. There, a special electronic device receives optical signal and converts it into an electric three-channel RGB-signal. After this signal processing the device outputs the data in digital form on the concentration of the searched substance. The analysis takes place immediately,” the project manager says.
This method allows the detection of almost all metals, organic materials and various pharmacological agents in water.
“Our method works with those substances with which interaction leads to color change. Indeed, this is not the whole range of substances. But universal methods do not exist. Today, the most widely used method for chemical analysis is spectrophotometry. A modern spectrophotometer costs about 500 thousand rubles, and it is a bulky stationary device. Our device can achieve the same quality of measurements, but it is compact and can cost about 30 thousand rubles at the market placement,” he says.
Such a device for rapid analysis is useful for environmental and related personnel of industrial enterprises. For example, oil companies can use the device for the determination of the tracers in the drilling fluid.
“To date, we have prepared a prototype device. Now we have set ourselves the task to use this method for a multi-component analysis. The fact is that the reagents that configure optode to a definite substance are sensitive to a few substances,” says Sergey Muravyov.”

New Arsenic Test -Using Bacteria?

Private Well Owner Outreach to Private Property Owners Association in the Poconos – Monroe County

The Keystone Clean Water Team was very happy to work with the local “Poconos Region” Property Owners Association to offer a private well water screening test for the residents drinking water.  For the 2016 program, a total of 16 residents participated in the program and for this program water testing was offered at two different tiers.  The basic tier provide general information related to the bacterial quality of the water and level of nitrate, iron, and total hardness.  The advanced tier provided testing for trace metals such as arsenic, copper, lead, zinc, and more comprehensive analysis of the overall quality of the water.  The following is a summary of the results:

2 samples were positive for total coliform bacteria, but no samples were positive for E. coli.;

1 sample exceeded the drinking water standard for lead and 5 other samples had detectable levels of lead in the water;

13 of the 16 samples contained detectable levels of nitrate, but at no point did the level exceed or approach the drinking water standard of 10 mg/L;

1 sample had elevated levels of manganese, but 3 had detectable levels of manganese in the water; and

15 of the 16 samples were considered slightly to corrosive to metal piping and 1 sample was considered very corrosive to metal piping.

The pH of the water ranged for 6.2 to 7.5 and only two samples had a pH that was less than the recommended drinking water standard of 6.5.  These samples were associated with water that had detectable levels of lead, but not the highest level of lead.  The sample with the highest level of lead appeared to be a sample collected at the kitchen sink after the water had been treated with a water softener.

From this snapshot, we learned the following:

  1. There appears to be a 13 % probability that a private well may contain total coliform bacteria.
  2. The water produced from the aquifer tends to be slightly corrosive and have total hardness that ranges from 30 to 150 mg/L.
  3. The groundwater does not appear to have elevated levels of nitrate.
  4. The groundwater does not appear to have E. coli. bacteria.
  5. Lead was detected in some water samples, but the occurrence in the well water is related to the corrosiveness of the water, type of water treatment, and type of plumbing fixtures in the home and not the groundwater aquifer.
  6. Homeowners that reported problems with sulfur odor or black particles were the same homeowners that had elevated or detectable level of manganese.
  7. If you are considering the use of a water softener, please consider the type of household plumbing and it may be necessary to install a neutralizing filter.

Based on these results, we recommend that all private well owners conduct an annual water quality test.  To facilitate this effort, the Keystone Clean Water Team offers an online mail order informational water testing program for private well owners throughout the USA and we offer our Know Your H20? Free Phone App. To learn about our mail order program, please visit us at http://www.water-research.net or http://www.knowyourh20.us.   If you have any questions, please call or email 570-335-1947 or bfenviro@ptd.net.

Understanding the Health Risks of Private Well Ownership

Understanding the Health Risks of Private Well Ownership
Guest blogger / writer – Julie Bowen <julie@palatino.org>

As a country, we are proud of our reputation for having the safest and cleanest drinking water in the world. However drinking water that is procured from privately owned wells is not regulated by the United States Environmental Protection Agency or many state agencies, meaning that the owners of those wells are responsible for ensuring that their water is safe and drinkable. Water from private wells tastes crisp and refreshing, and it can be a wonderful gift to own your own water source. It is also important to acknowledge that many residents living in rural areas have no choice but to procure their water from private wells or cisterns.  However, regardless of the reasons that their water is sourced from private wells, it is essential that private well owners are aware of the health risks involved in private well ownership as well as the myriad of benefits that they can obtain.  

The Risks of Water Contamination

Drinking water from wells can be contaminated in a variety of different ways:  either due to naturally occurring chemicals and minerals, the land use and farming practices in the area surrounding the well, and a malfunction of the wastewater treatment systems operating on the well itself. As a result of this, there are a wide range of illnesses that can be contracted via drinking contaminated well water. These can range from short-term gastrointestinal and stomach illnesses that includes nausea, vomiting and diarrhea to more severe long term illnesses such as reproductive problems, neurological disorders, and other chronic illnesses.  Death by drinking water is not common, but it has happened.  Individuals with compromised immune systems, as well as children, pregnant women, and elderly people, are more vulnerable to the effects of certain contaminates and should be especially vigilant about the quality of their privately owned drinking water.

Two of the parasitic illnesses private well owners should be most aware of are Hepatitis A and Giardia (which is the parasite that causes the illness giardiasis, a common cause of diarrhea). Giardiasis is a relatively short lived condition, that is caused by water becoming contaminated by either mammalian or human feces. The parasite itself is resistant to basic chlorination, meaning that it tends to be particularly resistant to water treatment methods, however once infected most individuals have overcome the illness in approximately 7 days. More deadly are the risks posed by the liver condition hepatitis A, which is a highly contagious illness that is also contracted via the fecal oral route, due to water contaminated by infected feces.  Hepatitis A is a self-limited disease that does not result in chronic infection, but the symptoms can be severe and pose a particular risk to vulnerable individuals.

Taking the Appropriate Precautions                      

Because of the risks of being exposed to contaminated drinking water, it is recommended that in addition to regularly checking the quality of your drinking water, and taking the necessary precautions to ensure it avoids contamination, private home owners also secure comprehensive health insurance.  This will help them to ensure that they are fully protected in the unlikely instance that something should go wrong with their water supply, and they should contract one of the myriad of illnesses listed above.                          

The Keystone Clean Water Team (KCWT) is committed to ensuring that home owners with responsibility for private wells are given the support, the information, and the technology that they need to ensure that their well based drinking water is as clean and as safe as possible. The quality of well water should be tested at least three times a year, and the well itself should be regularly repaired and maintained to protect the water that is inside. When it comes to modern well technology, knowledge is power, so it is important to be as informed as possible about what is happening inside your well, and well as any possible risks that you face. The process involved in maintaining healthy well water can seem complicated, and the language involved in the process unnecessarily convoluted, which is why The Keystone Clean Water Team can help homeowners interpret their test results and ensure their water is as safe as it can be.

A few thoughts from the KCWT:

  1. When people say may water taste great and looks great – I have no problem – 50% of the time they have a problem that can make them sick.
  2. Of these individuals, 50% of the time the problem can be eliminated for a few hundred dollars.
  3. Some recent work on lead in drinking water found that 2 out of 3 private well samples had elevated lead; whereas only 1 out of 10 city water samples had a lead issue.  Testing your well water quality is important, but you must understand our risks.
  4. Blood lead testing is important for kids – get it done if you are living an older community that has or had historic industrialization.

Installing a Rain Garden

Install a rain garden in your community  – Possible ROAs for a Groundwater Guardian Project

Spring is just around the corner, and a great time to think about installing a rain garden.  A rain garden is a garden of native shrubs, perennials, and flowers planted in a small depression, which is generally formed on a natural slope.  It is designed to temporarily hold and soak in rain water runoff.  Rain gardens help filter out pollutants such as fertilizers, chemicals, bacteria, and others contained in runoff.  They also incorporate native vegetation, reducing the need for fertilizers and after the first year, maintenance is usually minimal.

Rain gardens are effective in:

  • removing up to 90% of nutrients and chemicals
  • removing up to 80% of sediments from rainwater runoff
  • allowing for 30% more water to soak into the ground than a conventional lawn

Consider installing a rain garden as one of your team’s 2016 Result-Oriented Activities.  Remember, you can add an ROA at any time during the year.  Involve the public and make it an educational event!  Read more about how rain gardens benefit a community and how to get started.

Lead Drinking Water Crisis in Flint Michigan KDF

Lead- Metals- Corrosive Water
Water Quality Association Addresses Drinking Water Crisis in Flint, Michigan

Offers facts and tips about treating for lead contamination

Lisle, Illinois -The Water Quality Association (WQA), an Illinois-based not-for-profit organization, is offering informational resources to help with the drinking water crisis in Flint, Michigan. Flint residents are expected to receive federal aid to help ensure their access to safe drinking water. On January 16, 2016, President Obama signed an Emergency Declaration for the Federal Emergency Management Agency (FEMA) to coordinate all disaster- relief efforts. The declaration states that, “This emergency assistance is to provide water, water filters, water filter cartridges, water test kits, and other necessary related items for a period of no more than 90 days.”

Lead (Pb) has been identified as the waterborne contaminant of primary concern for Flint’s residents. To minimize the presence of contaminants such as lead, which may enter the water after it has left a municipal treatment facility, WQA recommends water treatment equipment that has been certified by an ANSI (American National Standards Institute)-accredited certification body. Such accredited entities include WQA’s Gold Seal Product Certification Program, NSF International and Underwriters Laboratory. Flint residents are encouraged to visit Lead in Water to search for the names of products certified by WQA for lead reduction. Click here to download a technical fact sheet about Lead (Pb).

It is important consumers follow the manufacturer’s instructions for maintenance. WQA also lists of water treatment professionals across the U.S. on its website at Lead in Water.
Additional notes
1. Recommend that we concentrate on the following – get kids and adults blood tested.
2. Get first flush testing completed for lead and alternative water source for drinking.
3. Install point of use treatment in the interim.
4. Develop a plan to remove the lead service lines.
5. Develop a plan to install corrosion control.
6. Lawsuits should wait until the problem is addressed.

Water Quality Association Addresses Frequently Asked Questions about Lead in Water

Lisle, Illinois -The Water Quality Association (WQA), an Illinois-based not-for-profit organization, is offering informational resources to help differentiate fact from fiction regarding the drinking water crisis in Flint, Michigan. The Association has compiled answers to several of the most common questions, while addressing some widespread misconceptions Flint residents may have about lead (Pb) in drinking water.

What are potential health effects from lead?

Lead poisoning often displays no outward symptoms; however, irritability, weight loss, vomiting, constipation, and stomach pain are possible signs to look for. Young children and pregnant women are at the greatest risk, even from short-term exposure. Reduced cognitive development and neurobehavioral deficits are associated with blood levels less than 10 micrograms of lead per deciliter of blood in children.[1] Therefore, there is no safe level for lead to be present in the blood of children.[2] Individuals will adsorb more lead if they have poor nutrition than those with better diets.

Can a Total Dissolved Solids (TDS) meter be used to detect lead in drinking water?

No. There have been some misconceptions around TDS Meters. These meters cannot measure lead specifically; they detect the conductivity directly related to the concentration of combined total dissolved solids such as minerals, salts and metals. The typical sample of tap water in the U.S. contains approximately 350 parts per million (ppm) of TDS[3], which, as a whole does not on its own indicate a health concern and in many cases is used as a means to enhance taste of water.  Lead concentration is found 1000 times lower at the parts per billion (ppb) level, and is too small to be detected without sophisticated instrumentation. Moreover, because TDS meters don’t measure individual ions, lead cannot be detected on its own.

Where can I go to get my water tested?

Water testing should be done be a certified testing laboratory.[4] WQA strongly recommends water testing be conducted at each point of use in accordance with appropriate sampling procedures. The water should be checked after a period of disuse before a specific water treatment product is selected. Water conditions can change, so the water should be tested both before a treatment product has been installed and at regular intervals following installation. Studies have shown the reported levels of lead found in some Flint, MI water results are higher than conditions under which the manufacturer set the replacement recommendations for filters in published manuals.

How do I maintain a filter once it is installed?

Always follow the manufacturer’s installation instructions and contact the manufacturer to confirm usage and capacity. To ensure the manufacturer can provide the most accurate recommendations, have test results for lead and iron on hand for review.

Where do I find a product certified for lead reduction?

American National Standards Institute (ANSI)-accredited entities offering product certification include: WQA’s Product Certification Program, NSF International, International Association of Plumbing and Mechanical Officials, and Underwriters Laboratory. To find products certified by WQA for lead reduction. Contact information for local professionals and manufacturers of certified products can also be found wqa.org.

PADEP pipeline task force gives 184 recommendations

Note Our Work – Email blast  from PIOGA

A state task force on natural gas pipelines is making 184 recommendations touching on everything from location of pipelines to emergency response plans, all designed to promote “responsible” pipeline development in Pennsylvania. The 335-page document, crafted by the state Department of Environmental Protection’s Pipeline Infrastructure Task Force, has been posted online for public review.

“It is important to remember that the report is not meant to be the final word,” said DEP Secretary John Quigley, who chaired the task force. “When we present our report to the governor in February 2016, I anticipate that the next step will be to determine the feasibility and implementation strategies for each recommendation.”

The 48-member task force was created in May by Governor Tom Wolf to develop policies, guidelines and tools to assist in pipeline development, operation and maintenance.

Recommendations in the draft were assembled by delegates from sectors affected by pipeline development, Quigley noted, including agriculture, communities, environmentalists, cultural resource advocates, industry officials, government agencies and emergency responders.

That lengthy list of recommendations starts with “educate landowners on pipeline development issues.” Other recommendations:

  • Implement full-time environmental inspections during pipeline construction.
  • Monitor water quality during construction.
  • Establish planning coordination between county agencies and pipeline developers.
  • Require pipeline abandonment plans.
  • Standardize emergency response plans and provide 911 addresses for pipeline-related facilities.
  • Do not locate pipelines parallel to waterways within their 100-year floodways.
  • Conduct early outreach with affected communities.
  • Minimize impact on local roads.
  • Create various statewide bodies and processes, including an all-region DEP pipeline review committee, a statewide pipeline information center for the public, and a DEP design manual for pipeline construction.

A 30-day public comment period on the draft report will run through December 14. [Read more]

Please note – there is no assumed responsibility associated with Pipeline Construction for Private Well Impacts – therefore it is important to document baseline conditions for your existing water sources and water wells.  Primary items of concern are aesthetic water quality issues, future methane and other gas releases, spills, local disturbances, discolored water, and related contaminants. The Know Your H20? App for Baseline Testing in PA should help.

Glyphosate Herbicide in Drinking Water Roundup

“Glyphosate is an herbicide that is regulated under the Safe Drinking Water Act. It is an ingredient in Roundup, a widely used herbicide, as well as more than 700 other products for sale in the United States.  Glyphosate is a non-selective herbicide used on many food and non-food crops as well as non-crop areas such as roadsides. When applied at lower rates, it serves as a plant growth regulator. The most common uses include control of broadleaf weeds and grasses hay/pasture, soybeans, field corn; ornamental, lawns, turf, forest plantings, greenhouses, and rights-of-way.

Some people who drink water containing glyphosate well in excess of the maximum contaminant level (MCL) for many years could experience problems with their kidneys or reproductive difficulties.  This health effects language is not intended to catalog all possible health effects for glyphosate. Rather, it is intended to inform consumers of some of the possible health effects associated with glyphosate in drinking water when the rule was finalized. In 1974, Congress passed the Safe Drinking Water Act. This law requires EPA to determine the level of contaminants in drinking water at which no adverse health effects are likely to occur. These non-enforceable health goals, based solely on possible health risks and exposure over a lifetime with an adequate margin of safety, are called maximum contaminant level goals (MCLG). Contaminants are any physical, chemical, biological or radiological substances or matter in water.

The MCLG for glyphosate is 0.7 mg/L or 700 ppb. EPA has set this level of protection based on the best available science to prevent potential health problems. EPA has set an enforceable regulation for glyphosate, called a maximum contaminant level (MCL), at 0.7 mg/L or 700 ppb. MCLs are set as close to the health goals as possible, considering cost, benefits and the ability of public water systems to detect and remove contaminants using suitable treatment technologies. In this case, the MCL equals the MCLG, because analytical methods or treatment technology do not pose any limitation.

The Phase V Rule, the regulation for glyphosate, became effective in 1994. The Safe Drinking Water Act requires EPA to periodically review the national primary drinking water regulation for each contaminant and revise the regulation, if appropriate. EPA reviewed glyphosate as part of the Six Year Review and determined that the 0.7 mg/L or 700 ppb MCLG and 0.7 mg/L or 700 ppb MCL for glyphosate are still protective of human health.” (EPA 2015)

While the United States classified glyphosate as non-carcinogenic when it was last reviewed in 1993, the World Health Organization published a study in March 2015 that indicates glyphosate is a probable carcinogen. Since the new study was released, there have been many questions asked regarding the safety of glyphosate. According to The Ecologist (June 12, 2015), several countries have banned or restricted use of the weed killer, including France, Columbia, Sri Lanka and El Salvador. In addition, many garden centers across the globe are pulling products that contain glyphosate off their shelves as a precautionary measure to protect customers. However, Roundup remains a staple herbicide in the United States.

Testing for glyphosate previously may have been cost prohibitive for many homeowners.  We have partnered with a national testing laboratory to provide a cost-effective alternative that also includes trace metals, volatile organics, and other organic chemicals.   For more information, please visit our Testing Testing and Evalatuion Protal but National Testing Laboratories (NTL) now offers a lower-cost test for detecting glyphosate in drinking water. Typical analysis by EPA-approved methods can cost $200 to $400, but the new package offers a much lower price to both water treatment professionals and homeowners.
