There is a lot of debate about fracking in the United States right now. There are valid arguments and scientific studies on both sides of the argument. This can make it hard to figure out who’s ultimately correct. On one hand, environmental activists argue that fracking is responsible for the pollution of drinking water. They point to the large number of chemicals used in the process of fracking, and make the point that some of these chemicals must be leaking into the watershed.

On the other hand, groups in favor of fracking point to the numerous safety precautions taken by drilling companies. These companies are regulated by a series of laws intended to protect the environment and local drinking water. Recently, defenders of fracking have been given another piece of evidence that is giving them a solid platform to backup their stance with.

That piece of evidence is a recent EPA (Environmental Protection Agency) report. In the report the EPA states that fracking does not threaten local drinking water supplies. The report took place over four years and looked at fracking activities across the United States.

The EPA concedes that in a few cases fracking wells have been responsible for contamination. However, they point out that these cases are few and far between. In fact, in cases where contamination has been detected, it almost always happens at wells that are violating one or more federal safety guidelines.

Fracking companies are also quick to point out that the chemicals they shoot into the ground are injected well below the watershed. In most places the watershed rests at about 2,000 to 3,000 feet. The wells that fracking companies drill go well below the watershed, up to depths of 9,000 feet. That means that these chemicals stay down in the ground, as they cannot go against gravity, and transition thousands of feet up to the watershed.

Companies also take extra precautions to preserve the watershed. All wells that are drilled have an additional amount of protection near the surface. Large amounts of concrete are poured around the fracking well closer to the surface, just as an extra precaution against any leaks.

All of these precautions protect drinking water from contamination. By following federal regulations and reinforcing wells near the surface, fracking companies strive to make their wells as secure as possible. These precautions are surely one of the reasons that the EPA concluded that fracking does not contribute to the contamination of drinking water.

However, no industrial process that uses as many chemicals as fracking can be completely clean and contamination free. Every year, rigs inject billions of gallons of fracking solution into the earth. Most of this solution is water and a small percentage is chemicals, lubricants and other compounds. Even though the solution is predominantly water, even just 2% of a billion gallons means 20 million gallons of pure chemicals.

One of the problems with fracking is that a majority of this solution is left behind in the earth. Depending on the well, only 30 to 50% of the solution used in fracking is recovered from beneath the ground. That means that every year a nearly unimaginable amount of polluted water is being left underground.

Problems also arise when that water is above ground. The fracking solution is usually stored in large tanks and ponds. Unfortunately, these storage areas are prone to dangerous spills. When fracking solution spills above ground, two things happen.

First, the solution sinks into the ground. Since thousands of gallons can spill at one time, this can add up to a significant amount of spilled solution. This water can sink down into the watershed. There, it gets mixed with clean water and is eventually used for drinking water.

The other problem associated with fracking solution spills happens when that water leaks into a local stream, river, pond or lake. When this happens the solution is carried off and it becomes mixed with pure, fresh water. This is a big problem because this type of leakage cannot be controlled. Once fracking solution leaks into a river, for instance, little can be done besides warning local residents about the danger.

More than anything else, there is one law associated with fracking that is alarming when it comes to the quality of drinking water. Fracking companies are exempt from the Clean Water Act and Safe Drinking Water Act. That means that their activities aren’t regulated by two acts which are explicitly designed to protect drinking water.

One of the larger problems with the question of fracking is that neither side has enough science to entirely disprove the other’s arguments. People who support fracking point out that spills are rare and many precautions are taken to protect drinking water.

Environmental activists argue that every year, fracking rigs use millions of gallons of potentially hazardous chemicals. Furthermore, they argue that by leaving these chemicals in the ground, fracking companies are risking watershed contamination.

Ultimately, the best way to solve the question is by doing your own local investigation. If you don’t live near a fracking rig then it’s likely you have nothing to worry about. If you do, you can take water samples and have them sent into the EPA for analysis.

It’s as likely as not that these samples will be fine and your drinking water is safe to drink. On the other hand, if there are chemicals present, you’ll be able to research them and discover if they potentially came from a fracking rig. Once you know what’s in your water, you’ll be able to take steps. Buying a water filter or filing an EPA complaint are all valid options.

Frogs and Toads at Sage Hill Herb Farm

I recently discovered Sage Hill Herb Farm in Petersburg, Tennessee and the owner, Bea Kunz.

About the Farm
Sage Hill Herb Farm consist of three acres under cultivation. A mix of wild flowers and grasses, much of those are native to Tennessee. Many raised beds which are always planted and growing vegetables and herbs along with fruit trees and berries for family and friends.

Their teas, herbs and seasoning blends are all carefully hand tended and organically grown without chemical pesticides or fertilizers.

They recommend that deep red or bright pink fruits and vegetables should be eaten every day. Nutrition research shows that foods in the red groups contain phytochemicals, such as lycopene and anthocyanins. Phytochemicals, substances found only in plants, help your body fight disease and promote good health.

Bogs and Frogs
And then there is the Bog! A beautiful and intriguing spot on the lower section of the back area where natural rock jutes through the ground. A wet weather stream keeps the area wet most of the time… providing a safe and natural habitat for frogs, toads and other little creatures who might come and go.

Below is a gallery shared by Bea of an American Toad, Green Tree Frog and Eastern Spadefoot and their natural habitat.

The Benefits of Frogs in Your Garden

Frogs and toads, just like so many other animal species, are suffering a decline in numbers. This is due to environmental problems, climate change and human factors and show that the changes we are seeing in the environment are signs that something is wrong.

What many people should realize is that frogs need to be viewed as an important part of the ecosystem.

The Benefits of Frogs in Your Garden

Frogs and toads are not only very beautiful and diverse (Frogs per Wikipedia – approximately 4,800 species); they can also prove to be very beneficial for your garden.

  • Every ecosystem is comprised of multiple species that create a chain. It is what keeps the balance in nature and what maintains life as we know it. As such, frogs and toads have their place under the sun and should be protected. This is the reason why you will do very well to ensure that frogs can find shelter in your garden. If you provide the right conditions and features for these amphibian creatures, they should appear.
  • Frogs are good bioindicators. There is a lot that you can learn from the frogs in your garden. Frogs can show you that something is wrong in the area, or if they are happily breeding and living in the area, then everything should be okay. If you are dedicated and want to have a perfect garden, you can use the indications from frogs to know if the conditions in your garden are good, or if the frogs that used to dwell there suddenly go missing, you will know there is a disturbance.
  • Pest control – frogs are amazing at cleaning the garden from harmful insects. If you are having such problems, you can easily eliminate them by introducing frogs among your plants. A single frog can eat over 100 insects, such as caterpillars, sow bugs and cutworms and more. These can destroy your entire garden if left unchecked. With frogs around, you won’t need to use harmful pesticides, either.

Toads and frogs can be one of the best solutions for your garden. Not only will you have a garden safe of bugs and insects, but you will also have very pleasant amphibians hopping around.

Blotched Tiger Salamanders in Oregon

This report comes from Frances in Southern Oregon.

Tiger Salamander in Southern Oregon

My two year old pond seems to have attracted these salamanders. I am in Southern Oregon, near Klamath Falls, and on the California border. I have been told they are Tiger Salamanders, but they do not have any bright coloring.

They are mottled and striped, and the largest one I have seen in my leaf trap was about 14″ long. The pond is about two and a half feet deep, so I can’t see how many there are, and if there are any of my goldfish left. Some of the fish were about 6 – 8 inches long when I last spotted them in late summer.

The salamander in the photo was on my driveway in early February of this year. I am pretty sure they are eating all the frogs we had. I am not hearing any croaking, and the two that frequented the rim of my hot tub are not around now. I am not sure if there is anything that can be done to balance things a bit, or if some of them are becoming permanent pond dwellers and not losing their gills, as I understand happens sometimes. Do you have any suggestions or ideas? Thank you. If these are some kind of hybrid, I don’t know how good they are for the environment.

*******

I sent this query along to a few experts and here are their responses:

Matt Ellerbeck – The Salamander Man says:

Your email/inquiry about salamanders was forwarded to me from Susan Newman at Frogs Are Green.

The salamander in the photo you sent is indeed a Tiger Salamander. They are variable in color, so if you Google searched them, it is possible that you came across images that didn’t resemble this individual salamander. Tiger Salamanders are native to Oregon so pose no environmental threat. On the contrary, salamanders are indicators of a healthy environment!

You also mentioned some concern for your frogs. Tiger Salamanders may occasionally take frogs, however, they primarily feed on insects and invertebrates. In fact, Tiger Salamander tadpoles (or larvae) prey on mosquito larvae and therefore help keep the number of these pests down! As such, I wouldn’t consider them a real threat to the frogs.

Due to the benefits they provide I hope you will accept the presence of these salamanders. If you want to learn about things you can to do help them (as they are both amphibians such efforts will also benefit frogs too) please visit the following: Save The Salamanders – How You Can Help

*******

I asked Matt why the frogs may have disappeared?

He replied:

Frances mentioned she didn’t hear the frogs croaking – perhaps the frogs are indeed still around but merely not singing at this time. I believe most frogs sing seasonally, or only at certain times. I have a backyard pond with frogs, and sometimes I may not see them for days on end, and suddenly they will reappear.

I have also read that cats will kill frogs, so they, or other predators (birds, snakes), may have taken them.

These are all plausible causes, however, I can’t say for certain. The reality is, any backyard pond (whether natural or human-man) that has animals in it will also attract various predators.

*******

Keith Gisser, Herpetologist and founder of Herps Alive! says:

Blotched Tiger Salamander. Pretty dull-colored animal normally compared to other (sub)species.

While pretty voracious eaters, rare (in my experience) for them to eat frogs or fish (although they will eat fish when in larval form) – they prefer invertebrates.

*******

Sara Viernum, Founder of The Wandering Herpetologist says:

Agreed! It’s a Blotched Tiger Salamander (Ambystoma mavortuim melanostictum). There is a small, known population (native) in southern Oregon near the border. Like all tiger salamander species these will eat anything that fits in their mouths including invertebrates, lizards, mice, snakes, frogs, tadpoles, small fish, and other salamanders. Since they are a native predator in your area they may initially cause a decrease in the local frog population but once they become established in your pond their numbers will most likely balance out with the frogs.

Keeping Your Pond Alive

The water in your garden pond is very sensitive to change. Depending on a number of factors, a pond can soon go from crystal clear to pea soup without any apparent explanation. You will quickly learn that pond pollutants can hide in the clearest water.

Filtration

An easy first step to ensuring a healthy pond environment is the use of a good filter and you should contact a specialist retailer, like Swell UK, who can advise you on the best solution. Biological filters will break down harmful toxins, like ammonia from fish waste, so they can be either removed or absorbed by the plant life in your pond. A UV filter will also help keep green water and algae at bay and keep down the levels of bacteria that could be harmful to the life in your pond.

A good water balance

High nitrate or pH levels in your pond can bring about the most common pond problem: algae. Algae can cause havoc in ponds, keeping light and oxygen from the plants and animals that need them. Regular testing should be carried out to keep on top of the environment in the water before an algae problem breaks out. You can pick up kits for any potential problem from online stores like Swell UK. These give you the all important heads-up you need to take action.

A key part of maintaining the right water balance is ensuring you use a good liner that will not only resist damage but ensure any outside nitrate sources, like fertilizer, are prevented from seeping through.

Oxygen

Oxygen plays a vital role in ensuring the good health of your pond. Without oxygen, certain bacteria found towards the bottom of ponds will begin to produce acids and toxins that will harm the fish, insects and helpful bacteria that may live in your pond. By planting particular oxygenating plants, you can create a natural balance of oxygen levels, but only during the day. By making use of an air pump or any water feature that will disturb the water surface, you can maintain a good oxygen level throughout the day, protecting the well being of your pond.

Frogs and Water Quality

Yesterday, in class with the Cloud Institute and Sustainable Jersey (NJ Learns), each student got to briefly share their project, so I was describing the Frogs Are Green mission and projects on the agenda for 2015.

My teacher Jaimie P. Cloud, challenged me with this question. “Much of what Frogs Are Green is about is bringing awareness to the public, but is there a change I want in the public’s behavior?”

It made me think about one specific area that we can focus on which would help frogs and amphibians as well as other wildlife and humans, and that is water quality.

We know that there are many issues, such as, pollution and oil spills, pesticides and other toxins, pharmaceuticals, and these aren’t just affecting wildlife, but us as well. It’s humans that are creating many of these problems, so it’s obvious that we must be the ones to correct it.

testing water quality

I did a search on Google for Frogs and Water Quality and was surprised to learn there is currently no standard for water quality as it applies to frogs and amphibians:
“The factors thought to be contributing to declines in frog populations include habitat loss, introduction of exotic species, overexploitation, disease, climate change, and decreasing water quality. With respect to water quality, agroecosystems use 80-90% of the water resources in the western United States, frequently resulting in highly eutrophic conditions. Recent investigations suggest that these eutrophic conditions (elevated pH, water temperature, and un-ionized ammonia) may be associated with frog embryo mortality or malformations. However, water quality criteria for frogs and other amphibians do not currently exist. Here, we briefly review data that support the need to develop water quality parameters for frogs in agroecosystems and other habitats.”
(from this website: PMC1519110/http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1519110/)

What this tells me is that currently the water quality is tested to make sure it’s safe for humans, but there are no regulations in place for it to be safe for wildlife? Doesn’t it matter that it’s healthy for all life?

I’ll be reading much more on this issue and would like to invite you to share your thoughts or links to additional documentation you may have found.

Here’s a video I’d like to share because it shows just how important it is to educate the young with hands-on education from Marie Hartford, Science, 5th Grade Teacher and her students in Redmond, WA on the Teaching Channel about “Measuring the pH as it Relates to Water Quality.”
