ODORS IN DRINKING WATER - Smells can indicate problems with the water supply, some of which could lead to serious health effects. There are many different possible causes for odor, and the cause of the odor can be difficult to determine. The odor may come from the water itself, or it may come from where the water is obtained, such as a sink. To determine if the odor comes from the water itself, you can pour the water into a glass and test its smell away from the sink. If the water does not smell, the odor may come from the sink drain. Odors in sink drains may be caused by bacteria that feed on the food, hair and soap particles that accumulate in the drain. These bacteria can be killed by disinfecting and flushing the drain. Odors can also originate in the plumbing system. Organic matter can become trapped inside pipes, which can cause sulfurous odors. This organic matter can also react with chlorine, which produces odors.

Odors in Drinking Water

People are naturally uneasy about drinking water that has a strange smell.

This is a good thing, because strange smells can indicate problems with the water supply, some of which could lead to serious health effects.

However, there are many different possible causes for odor, and the cause of the odor can be difficult to determine.

The odor may come from the water itself, or it may come from where the water is obtained, such as a sink.

To determine if the odor comes from the water itself, you can pour the water into a glass and test its smell away from the sink.

If the water does not smell, the odor may come from the sink drain.

Odors in sink drains may be caused by bacteria that feed on the food, hair and soap particles that accumulate in the drain.

These bacteria can be killed by disinfecting and flushing the drain.

Odors can also originate in the plumbing system. Organic matter can become trapped inside pipes, which can cause sulfurous odors.

This organic matter can also react with chlorine, which produces odors.

If the odor goes away after a few minutes of running the water, then the source of the odor is probably in the household plumbing system.

If the odor persists and occurs in all faucets, then the odor is likely coming from the water supply rather than the household plumbing.

If the odor only occurs in some faucets, then the source of the odor may be in that part of the plumbing system.

“Odor in well water may indicate contamination from an improperly located septic tank”

In well water, odors can come from contamination from surface runoff, sewage or septic systems, or leaky underground storage tanks.

Odors in well water can also be caused by bacteria growing in the well. In this case, you can shock chlorinate the well and then pump until the odor disappears.

Odor in well water may also indicate contamination from an improperly located septic tank.

This may be fixed by relocating the septic tank, drilling a new well, or tapping a different aquifer using the existing well.

Odors in Hot Water

If the odor only occurs in hot water, the source of the odor may be the hot water heater.

Odors can originate in hot water heaters if they are unused for too long or if the temperature is set too low, which allows bacteria to grow.

This problem can often be fixed by flushing water through the tank.

If the tank has not been recently unused and the temperature has not been set too low, the magnesium rod in the hot water tank may be the cause of the odor.

This can be fixed by replacing the rod.

Identifying the Source of Other Odors

The sources of some other odors may be interpreted according to their smell.

“A turpentine-like odor may indicate contamination with MTBE (methyl tertiary butyl ether), a common gasoline additive that is notorious for its ability to move quickly through groundwater and contaminate aquifers.”

Bleach, medicinal or chemical smells can be caused by chlorine in the water supply. These smells should go away after the water stands for several minutes.

Sometimes, extra chlorine is added to a water supply for a short time if extra disinfection is needed.

This is known as shock chlorination, which usually produces a strong bleach odor, but it should go away after the water runs for several minutes.

Musty, moldy, earthy, grassy or fishy smells may indicate bacteria growth in the drain or contamination of the well with surface runoff.

Bacteria growth in a sink drain is the most common cause of these types of odors.

In the home plumbing system, bacteria growing in a reservoir or pressure tank can also cause these odors. Cleaning and maintenance of the tank can often fix this problem.

Growth of algae, fungi or bacteria in the water supply can also produce these odors.

If the amount of chlorine in a municipal water supply is insufficient, then bacteria may be able to grow in the water pipes, which can cause these types of odors.

Fuel-like or solvent-like odors (petroleum, gasoline, turpentine, etc.) may indicate contamination from a leaky underground storage tank or pollution from factories, landfills, or agricultural runoff.

A turpentine-like odor may indicate contamination with MTBE (methyl tertiary butyl ether), a common gasoline additive that is notorious for its ability to move quickly through groundwater and contaminate aquifers.

Contamination with these types of odors may lead to serious health effects, so an investigation of the nature of the contamination is advised.

Water with this type of odor should not be used until either the source has been taken care of or the water has been adequately treated.

If the cause of the problem cannot be eliminated, then the water can be treated using activated carbon filtration.

Detergent odor (sometimes accompanied by foaming water) is usually associated with contamination from a septic system.

 In this case, the source of contamination should be eliminated, and the well should be treated with shock chlorination.

Sharp chemical odors may indicate contamination by pesticides or other chemicals.

Cucumber-like odors are often associated with iron-loving bacteria.

These bacteria often appear as an orange slime in toilet tanks, which can also produce a sewage-like smell.

Other microbes such as protozoa can also produce a cucumber smell in water.

“Rotten egg” (sulfurous), sewage-like or decayed odors are usually caused by bacterial activity.

This may occur in a sink drain, water pipes, or the water supply.

Interesting fact: Humans can detect trillions of distinct smells.

Is the Smell Real or My Imagination?

Everyone has a different sense of smell, so water may smell differently to different people, and people also differ in their ability to sense smells.

If only one person senses a smell, this may be because of a health problem with that individual rather than a problem with the water.

However, it is still a good idea to check out potential water quality problems associated with smells, even if only one person notices it.

Treating Drinking Water for Odors

If the source of the odor cannot be eliminated, persistent odors can be treated using activated carbon filters, automatic chlorination followed by an activated carbon filter, or ozonation.

Granulated activated carbon (GAC) filters are simple to use and inexpensive.

These filters remove contaminants that stick to small particles of material such as coal or charcoal.

They can take the form of point-of-use systems (such as at a kitchen sink) or pitchers manually filled with water.

GAC filters should be replaced or regenerated periodically so that they remain effective.

A chlorination system oxidizes substances that can cause odors, in addition to chemically killing microorganisms.

This type of system adds chlorine (in liquid or solid form) to the water through a continuous feed system.

Because sediment in the water could interfere with the chlorination, a filter should be placed before the chlorine injector.

Chlorine is consumed as it reacts with impurities in the water (such as iron, microbes or organic matter).

To ensure adequate disinfection and neutralization of odors, enough chlorine needs to be added so that there is a small amount left over after it is consumed.

However, this residual chlorine can cause a noticeable chlorine taste in the water, so it may be desirable to remove it before drinking.

Chlorination also requires a certain amount of contact time in the water for it to kill microorganisms and neutralize odors (usually 30 minutes).

This is why water is usually stored in a large holding tank or run through a series of coiled pipes after being chlorinated.

Chlorine systems must be maintained to make sure that they function properly, and the chlorine supply must be periodically replenished.

Ozonation is similar to chlorination in that ozone is injected into the water, neutralizing odors and killing microorganisms.

Ozone is produced using electricity and then injected into the water.

Ozonation systems are more expensive than chlorination systems, but they can treat water for multiple contaminants, such as viruses, bacteria, iron and manganese, in addition to odors.

"Rotten egg" smell, which can also be sulfur or hydrogen sulfide in well water, can be treated by an oxidation-reduction medias such the one used in our iron and hydrogen sulfide removal systems.

PHONE TOWERS AND CANCER - Phone towers are not the only thing we should be worried about; phones and routers are similar to miniature towers themselves. In fact, not only are they greater in number, but they also lie much closer to us than most cell phone towers do. Microwaves generating non-ionizing radiation are harmless, but concentrated microwaves can penetrate our skin and burn tissues; this is exactly how ovens work! Antennas are generally mounted on top of tall towers or buildings, which causes the power levels of the emitted radiation to dwindle as it descends toward the ground. At ground level, the emission is 1000 times lower than the limits for safe transmission set by the Federal Communication Commission (FCC). In other words, damage is highly unlikely. Second, the signals are not transmitted constantly, but intermittently.

Microwave OvenPhone Towers And Cancer
Do Phone Towers Cause Cancer?
Akash Peshin  


Well, the answer isn’t an outright no. One can find some solace in the fact that the evidence for the case hasn’t been conclusive.
Right now, at this very moment, you are drowning in an ocean of electromagnetic radiation. Its waters are a myriad of radiation – radio waves, the sun’s light, infrared and all the rest.
Initially, the world was dominated by the sun’s light and infrared radiation, the harbingers of heat.
Now, however, with the construction of soaring phone towers and the ubiquity of smartphones, radio waves seem to be growing in domination.
The notion of whether phone towers pose a health risk has been speculated for decades.
The presence of towers and cell phones concerned people even at times when mobile devices were a luxury – complex technological equipment that only a few people carried.
The situation today seems to cause even more apprehension – cell phones are as common and necessary as footwear, every household has a router, and to accommodate both of these, radio towers are planted more often than trees.
Ionizing vs Non-ionizing radiation
Any type of fear is largely spurred by uncertainty, which is essentially a lack of information.
In this case, the fear of phone towers seems to be fueled by our lack of understanding of electromagnetic physics.
The seven types of electromagnetic radiation can be categorized into two classes based on their energies: ionizing and non-ionizing radiation
Ionizing radiation represents the high-frequency spectra of electromagnetic radiation, which includes high-frequency ultraviolet rays, X-rays and gamma rays – remnants of a nuclear aftermath.
Prolonged exposure to these emissions can cause cellular mutation, which can lead to various cancers. This is because, as the name suggests, they tend to ionize and destabilize molecules.
These high-frequency waves are so energetic that they interact with matter as if they are individual particles, colliding and kicking matter’s constituents out of their stable structures. 
Exposure to such an energetic radiation disrupts the structure of DNA, a major cause of cancer and other autoimmune diseases.
On the other hand, non-ionizing radiation represents the low-frequency spectra of electromagnetic radiation.
These include radio waves, microwaves, infrared and visible light.
Owing to their low frequencies, these waves travel with very low energies, rendering them non-ionizable — they are unable to knock particles away from stable molecular structures.
The fact that low-frequency waves aren’t energized enough to disrupt DNA molecules implies that the radio waves constantly emanating from phone towers are harmless.
Even so, could constant exposure to them, like an interference pattern, positively add up to threaten us with a fatal health risk?
The fear is most likely to be observed in parents who are apprehensive about radiation affecting the developing brains and bodies of children.
Are these apprehensions justified? Let’s see what the experts have to say.
They are “possibly carcinogenic”
Phone towers are not the only thing we should be worried about; phones and routers are similar to miniature towers themselves.
In fact, not only are they greater in number, but they also lie much closer to us than most cell phone towers do.
Microwaves generating non-ionizing radiation are harmless, but concentrated microwaves can penetrate our skin and burn tissues; this is exactly how ovens work!
So… should we be worried? Well, the answer isn’t an outright no.
One can find some solace in the fact that the evidence for the case hasn’t been conclusive.
This is reflected in the World Health Organization’s (WHO) International Agency for Research on Cancer (IARC), which deems radio transmission “possibly carcinogenic” — towers don’t seem to pose a threat, but we aren’t sure.
However, there are multiple reasons why they might be harmless.
First, antennas are generally mounted on top of tall towers or buildings, which causes the power levels of the emitted radiation to dwindle as it descends toward the ground.
At ground level, the emission is 1000 times lower than the limits for safe transmission set by the Federal Communication Commission (FCC).
In other words, damage is highly unlikely.
Second, the signals are not transmitted constantly, but intermittently.
However, could the radiation affect people who live in the vicinity of these towers, such as people living right below the roof or inhabitants of buildings whose windows face towers mounted on a shorter building directly adjacent to them?
The answer is still “No”. Cement, wood and other obstructions attenuate signals, thereby deterring any copious amounts of potentially harmful radiation.
The power levels are known to be at a maximum right next to the antenna, so access to the places with direct exposure might be limited.
Still, a lack of studies relating to residents living near a glut of towers and their likelihood of cancer hasn’t allowed any definitive conclusion to appear.
