Today we received a question from NicholasG asking about something called… ‘a sulfur water test’.

Don’t know if you can help, but what in the world is a sulfur water test? An older couple came by to look at our house today and before they left the man asked us the last time we had a sulfur water test done. So what is a sulfur water test and why did he ask that?

NicholasG

Given that he asked about a ‘sulfur water test’, we will assume your home has a private well as its water supply. The term ‘sulfur water test’ usually refers to any test that detects dissolved hydrogen sulfide in water.

Why would drinking water contain hydrogen sulfide?

Pinpointing the exact source of hydrogen sulfide in water sometimes takes a bit of effort. The gas occurs naturally in groundwater and may come from microorganisms referred to as ‘sulfur bacteria’. That same type of bacteria may also exist in a well and or in the water distribution system after a well. To make matters even worse, sulfur bacteria may also live in water heaters and chemical reactions within certain types of water heaters can also result in the addition of hydrogen sulfide to water.It can be produced also by sulfur bacteria or chemical reactions inside water heaters.

Though not nearly as common, specific types of pollution may also add hydrogen sulfide to a water supply.

Sulfur bacteria and hydrogen sulfide… Dangerous?

Most times a rotten egg smell coming from water does not mean the water poses a significant health risk. But, in the absence of other contributing factors, one should always remember that in rare cases hydrogen sulfide may occur as a result of a contamination from sewage or other types of pollution — and in those cases serious and/or life-threatening health hazards may exist.

As a precautionary measure, we suggest that anyone whose water suddenly develops a rotten egg smell have their water tested for other water parameters such as coliform bacteria and nitrates, as unsafe levels of either in water make the water unsafe to drink non-potable and unfit for human consumption.

Another thing to remember about hydrogen sulfide gas, at high levels in the air it poses a danger. Therefore one should always take steps to properly vent any area where the gas may build up, such as around the well head, basements where well water enters, etc. Entering an area that has a built up hydrogen gas in the air could very well prove fatal without the right protective gear so if a you suspect a buildup, call in a professional.

Testing for hydrogen sulfide in water… Difficult?

Before you can choose a hydrogen sulfide removal systems you must first know how much you have present — or risk purchasing and installing the wrong size or type of filter!

While the majority of people will have the ability to pick up the distinct aroma (odor!) of rotten eggs in a sample of water, most people do not know that it takes only a small amount of hydrogen sulfide gas in water to make quite a huge stink. Therefore you will need a test kit for hydrogen sulfide to determine how much you have.

For drinking water applications, the Low Range Hydrogen Sulfide Test Kit will work quite well since it has a low detection level of 0.3 parts per million hydrogen sulfide and an upper detection limit of 2.0 ppm. Most people with a hydrogen sulfide problem will have a level somewhere in that range.

Testing for hydrogen sulfide in industry?

OK, since we know some people in industry have uses for water containing much greater concentrations of hydrogen sulfide, we figure they, too, may want to test hydrogen sulfide levels — and for them we suggest the WaterWorks Hydrogen Sulfide Test Kit which has a detection range of 5 ppm to 80 ppm and gives results in under a minute.

Now before you freak out, keep in mind that the presence of fecal coliform bacteria in a body of water does not necessarily mean the water will cause a person to get sick… or die. Also, this sampling included, for the most part, outside bodies of water, not drinking water supplies.

So having said that, why should residents in that area care if ponds, streams, rivers, lakes, etc. contain fecal coliform bacteria? Simple: The presence of such a contaminant serves as a warning flag that somehow, in some way, sewer and septic systems have failed to contain human waste… and it has found a way to seep into the environment untreated.

If enough untreated sewage finds its way into the environment, a good chance exists that it may one day also find its way to a popular swimming hole in a local creek, drift around until it lingers just off the shore of a lake where people wade to cool off, and possibly even seep down into the ground where it could enter an aquifer that provides water to wells servicing the homes of unsuspecting families.

Officials in Augusta have broadened their examination of water downtown after an Augusta Chronicle analysis found elevated levels of fecal coliform bacteria.

The sampling began Monday after the newspaper published a report Sunday revealing the results of water sample testing from 50 locations in Richmond, Columbia and Aiken counties.

Fecal coliform bacteria indicates that pathogens may be present and could pose a risk to human health.

Garrett Weiss, manager of the Augusta Engineering Department’s Stormwater and Environmental Section, says his department has been aware of some of the problems and is moving to correct them.

He said old, hidden sewer lines that aren’t properly hooked up to sanitary sewer systems may be to blame for the high levels. ( source )

I you or someone you know has reason to suspect contamination of their water supply with coliform bacteria or any other potentially harmful chemical element, compound, or organism, seek the assistance of a certified water testing laboratory in your area. If no labs exist in your immediate area, or they have extremely high testing rates, contact your local health department or take a look at the water testing services offered by companies like National Testing Laboratories.

Water Testing Blog loves to hear about local health departments taking the initiative to try and get residents to test their well water for potentially harmful contaminants. In this case, the health department in McHenry County, Illinois has stepped up to the plate by offering coliform bacteria and nitrate testing at a reduced cost until the end of August.

WOODSTOCK – McHenry County Department of Health will offer reduced fee water testing for individual well water users during the month of August.

Residents can have their well water sampled for coliform bacteria and nitrate for $18.

Testing wells regularly is the only way to determine whether well water is safe to drink, as many contaminants are colorless and odorless.

Water from a public or municipal water system regularly is tested for contaminants regulated by federal and state standards.

Bacteria and chemicals can get into well water and contaminate it in different ways.

Some bacteria and chemicals occur naturally.

Contaminants, such as nitrate, can come from animal waste, wastewater, flooded sewers, polluted storm water runoff, fertilizers, agricultural runoff, or decaying plants. High levels of nitrate in drinking water can cause illness in young children and pregnant women. Coliform bacteria are microbes found in the digestive systems of warm-blooded animals, in soil, on plants, and in surface water.

For a nominal charge, the health department also will sample private wells for nuisance chemicals resulting in water hardness, iron, discoloration and odor.

Sampling kits can be picked up at the health department in Woodstock or at one of eight drop-off centers. Samples can be dropped off for testing Tuesday mornings between 9 a.m. and noon at the following centers:

• Algonquin Township Office, 3702 Route 14, Crystal Lake; 847-639-2329.

• Dorr Township Office, 140 Newell St., Woodstock; 815-338-0125.

• McHenry Township Office, 3703 Richmond Road, McHenry; 815-385-5605.

• Nunda Township Office, 3510 Bay Road, Crystal Lake; 815-459-4011.

• Marengo City Hall, 132 E. Prairie St., Marengo; 815-568-7112.

• Harvard Police Department, 201 W Front St., Harvard; 815-943-4431.

• Richmond Township Office, 7812 S. Route 31, Richmond; 815-678-0077.

• Grafton Township Office, 10109 Vine St., Huntley; 847-669-3328.

Many people believe coliform bacteria only get into OTHER people’s wells because THEY did something wrong… but in reality, something as simple heavy periods of rain causing a rise in the water table supplying a person’s well could result in the introduction of potentially harmful contaminants.

Also, the slightest crack in a well’s casing, which could come from age or a shifting in the ground surrounding the well, could serve as a very convenient point-of-entry for bacteria or other well water contaminants.

If we had a nickel for every single time someone asked us what NSF 42, 44, 53, 55, 58, 62 and 177 meant… we’d have a huge pile of nickels and STILL not have enough money for that diamond-plated, gold-encrusted, platinum embossed drinking fountain w/ the GIANT water purification FACTORY attached to it from the other side of the wall.

NSF/ANSI Standard 42: Drinking water filtration systems that are certified to this standard remove chlorine and sediment/particles from water for the purpose of improving its look, smell and taste. The design of these filter do NOT lend themselves to the removal or reduction of health-related contaminants.

NSF/ANSI Standard 44: Water treatment systems certified to this standard typically function as cation exchange water softeners designed to reduce or eliminate water hardness (i.e. calcium and/or magnesium). Water filters designed to remove barium and radium may also certify to this standard.

NSF/ANSI Standard 53: Water purifiers certifying to this standard have designs that remove health-related contaminants such as waterborne organisms and industrial chemicals. Cryptosporidium, giardia, volatile organic chemicals (VOCs), MTBE (methyl tertiary-butyl ether) and trihalomethane compounds (THMs) fit into one of those categories or the other.

NSF/ANSI Standard 55: Devices rated to this standard function as point of use (POU) or point of entry (POE) ultraviolet microbiological water treatment systems. These water treatment systems feature designs which disinfect microorganisms (such as bacteria and viruses) potentially present in water.

NSF/ANSI Standard 58: Typically one will find reverse osmosis water systems (RO) certified to this standard. Devices in this category will normally have the ability to fully remove organic contaminants, but may only partially remove inorganic compounds and heavy metals.

NSF/ANSI Standard 62: Certified to this standard one will typically find water distillers. The process of distillation removes a wider range of drinking water contaminants than all other methods of drinking water purification. Arsenic, mercury and bacteria all get eliminated through the use of water distillation systems.

NSF/ANSI Standard 177: Water filtration units certified to this standard function as shower head filters designed to remove chlorine from water.

The fourth and final stage, a bed of granulated activated carbon (GAC) reduces chlorine by 99.9%, gets rid of bad tastes and odors, reduces pesticides and chemicals that are linked to cancer risks (i.e. benzene, THM’s, toxaphene).

How do you know if you need a water filter?

The answer, quite simply, involves testing your water. You can either test it yourself using a home water testing kit like the Water Quality Test Kit from SenSafe… or you can have a certified water testing laboratory such as National Testing Labs analyze your water.

In cases where homeowners suspect contamination, we always suggest using a certified water testing lab. Better to play it safe than sorry because… It’s your water, your health… and your LIFE!

Ewwwww…… Yuck!

Could bacteria really live in the trusty water coolers at work or in your home? Unfortunately we have to say… “YES.”

Think of it this way: When you swap out the large, cumbersome jugs when the current jug runs out of water, the feeder tube that will stick into the new jug gets exposed to the air… and whatever bacteria, viruses and or airborne biologicals happen to blow around in the room that day.

Over time any of those nasty little buggers that land on the feeder tube and wind up in the fresh jug of water could multiply to dangerously high numbers in the water cooler. Zero disinfectants in the water creates an excellent place for bacteria to start a family!

To make matters worse, the area AFTER the feeder tube down inside the water cooler can also become a nice place for bacteria and other nasties to raise a family… which could one day wind up in your supposedly safe glass of drinking water.

Moral of the story?

If you cannot determine the last time anyone cleaned the inside of the water cooler, you may want to test the water it dispenses for potentially harmful bacteria with a kit like the WaterSafe Water Cooler Test Kit.

Some folks have written in recently to tell us that they seriously doubt the ‘hype’ about waterborne illnesses from contaminated swimming pools, hot tubs, etc. In response to their doubts, we now present you with an actual case where health officials shut down a water feature park in Columbia, SC because a person who had visited the park recently tested positive for an intestinal parasite known as Cryptosporidium.

Columbia, SC (WLTX) – The Drew Splash Pad is closed while health officials test to see if the water there has an intestinal parasite in it.

The Splash Pad, which opened last year, is located behind the Drew Wellness Center in Columbia.

City park officials closed the pad Thursday after they were told by health officials that there was a possible link between the splash pad and one confirmed case of cryptosporidium.

Cryptosporidium is a parasite spread through feces. It’s normally found in fresh waters. It can cause diarrhea, abdominal cramps, headaches, nausea, vomiting, and a low-grade fever.

Symptoms can last up to two weeks.

City pools remain open to the public. ( source )

Moral of the Story? Proper hygiene and diligent water testing DO matter when it comes to keeping the general public safe. Hopefully the folks in the Health Department down in Columbia, SC will find the source of that Cryptosporidium quickly and wipe it out before more people get sick.

We recently received an email inquiry from Lisa containing a question about water treatment systems for people with compromised immune systems.

My son has just been diagnoses with an immune deficiency, and I should be sterilizing his drinking water -which I am doing by boiling for him. I am wondering if distilled or reverse osmosis, bottled water would effectively remove bacteria from the water, and be a safe alternative. Would one be better then the other.

Thank you for your time,

Lisa

Thank you, Lisa, for your question and it pains us to learn of your son’s condition. We hope that modern medicine can find a way to help your son live a long and healthy life.

Regarding your question about the best way to sterilize water for people with compromised immune systems, the EPA and CDC co-released a document back in 1995 that gives a lot of useful information on the topic entitled Guidance for People with Severely Weakened Immune Systems.

Below you will find excerpts from that document relating directly to the questions you asked:

• Cryptosporidium has caused several large waterborne disease outbreaks of gastrointestinal illness, with symptoms that include diarrhea, nausea, and/or stomach cramps. People with severely weakened immune systems (that is, severely immunocompromised) are likely to have more severe and more persistent symptoms than healthy individuals. Moreover, Cryptosporidium has been a contributing cause of death in some immunocompromised people.

• Although data are not sufficient for EPA/CDC to recommend that all severely immunocompromised persons take extra caution with regards to their drinking water, individuals who wish to take extra measures to avoid waterborne Cryptosporidiosis can bring their drinking water to a full boil for one minute. Boiling water is the most effective way of killing Cryptosporidium.

• Only point-of-use filters that remove particles one micrometer or less in diameter should be considered. Filters in this category that provide the greatest assurance of Cryptosporidium removal include those that use reverse osmosis, those labeled as “Absolute” one micrometer filters, or those labeled as certified by NSF International under standard 53 for “Cyst Removal.” …. Water treated with a point-of-use filter that meets the above criteria may not necessarily be free of organisms smaller than Cryptosporidium that could pose a health hazard for severely immunocompromised individuals.

• Many, but not all, brands of bottled water may provide a reasonable alternative to boiling tap water. …. Any bottled water treated by distillation or reverse osmosis before bottling assures Cryptosporidium removal.

• Neither EPA nor CDC maintains a list of point-of-use filters or bottled water brands that meet the above criteria. NSF International can provide a list of filters that meet the NSF criteria.

We suggest you take a look at the NSF Web Site to see what systems meet their requirements. In a situation like yours, you will want to make certain the product you purchase will accomplish all your objectives — and then some.

One system we came across recently, the Pentek RO-3500 Monitored Reverse Osmosis System,

NSF Tested & Certified Standard 58 for reduction of TDS, Fluoride, Turbidity, Lead, Nitrates, Selenium, Arsenic, Copper, Cadmium, Barium, Cyst, and Radium.

The Pentek R0-3500 features the 3 stage system, one ROM-230TN membrane, a D15 sediment filter, a D20 carbon filter, and one long-reach lead-free faucet. Unit comes with a standard installation kit and instructions.

Another feature of the the Pentek RO3500 which makes it quite nice… an electronic monitoring system that keeps track of the water filters cartridges’ lifespans and informs the owner when they need replacing.

What elements does the RO-3500 Reverse Osmosis System reduce and/or eliminate? The unit has the ability to filter out the following elements as well as many other chemical compounds:

• 90.2% TDS ( test for TDS )
• 98.9% Arsenic ( test for arsenic )
• 90.5% Fluoride
• 98% Phosphates ( test for arsenic )
• 99.99% Cysts
• 99.7% Turbidity
• 98.7% Lead ( test for lead )
• 87.4% Nitrate ( test for nitrates )
• 80.7% Nitrite ( test for nitrites )
• 97.5% Selenium
• 99.9% Copper ( test for copper )
• 97.3% Cadmium
• 86.6% Hexavalent Chromium ( test for chromium )
• 92.8% Trivalent Chromium
• 80% Radium 226/228
• 90.7% Barium
• Chlorine ( test for chlorine )
• Sediment & Particulates

For more information on the Pentek Reverse Osmosis System mentioned above, please read its detailed specifications on FiltersFast.Com.

One final word

Use of a reverse osmosis systems does NOT guarantee the elimination of ALL possible biological contaminants since some biological contaminants have sizes smaller than the membranes in RO units can filter out.

For that reason you may want to consider adding a UV Sterilizer to your filtration setup. These devices render biological contaminants incapable of reproducing by altering their genetic structure with specific wavelengths of light.
