“Why is my lawn green? A healthy lawn is the sign of a healthy home and my lawn is yellow. Allthe lawns here are yellow and we all fertilize and feed and do all we’resupposed to but the lawns are still yellow. Could it be the water?”

Sad to say, but the little kid in us wants to say, ” Gretchen, your neighborhood needs a leash law to keep wandering dogs from peeing all over your lawns!” Ha ha. Yep. The kid in us has not, yet, grown up all the way… and we hope it never does! 🙂

On a more serious note, if every lawn in your neighborhood has the same issue (bad grass), then it stands to reason that all of your lawns have at least SOMEthing in common. Typically all yards in a development will share a similar soil type (i.e. composition, pH, etc.), environmental conditions (rainfall, amount of sunlight, etc.) and quality of water used to keep them hydrated.

Since we know very little about soil we will pass on the opportunity to discuss that topic and move in for the kill on a topic we DO know something about: Water. Since you say your lawns stay yellow, a sure sign of a dead or dying lawn, perhaps your lawns don’t particularly care for something in the water?

As our first guess, we cast our vote for chlorine. Most municipal water systems use a form of chlorine to keep biological contaminants from growing in the water and water lines. Once out of the water line, however, chlorine will continue to wage war on biological organism… like the grass in your lawn.

Chlorine in my water?

How do you know if your tap water contains chlorine? Perform a simple test for chlorine using a product such as the WaterWorks 2 Free & Total Chlorine Test Strip. We like this product because it provides reliable test results for both free and total chlorine concentrations in water at the same time and in just a few minutes.

There’s chlorine in my water… Now what?

Well if the chlorine poses a problem (i.e. it kills your grass!) then we heartily suggest removing it from the water you use on your lawn. The products below from Gar’n’Gro should have the ability to help with that task.

For those interesting removing chlorine from their drinking water, you may want to consider installing a simple, yet effective, faucet filter such as the Crystal Quest W2 in your kitchen.

“Drinking or even showering in tap water can double the risk of having deformed children,” says study.

Drinking tap water while pregnant may double the risk of serious heart or brain defects in the unborn child, research suggests.

A study of almost 400,000 babies found a clear link between chemicals formed during chlorination and the occurrence of a trio of birth defects.

Drinking water, showers, swimming pools and even the steam from a boiling kettle can all contain the problem chemicals called trihalomethanes, or THMs, the researchers said.

While the study was carried out in Taiwan, it is thought up to one in six British homes is exposed to levels even higher than those found to cause concern, with concentrations tending to be particularly high in the spring and autumn.

The researchers stressed it would be impractical for pregnant women to avoid tap water and said the onus was instead on the use of disinfection methods which limit levels of the chemicals.

The Birmingham University study compared details of birth defects with the level of THMs in tap water.

The analysis of almost 400,000 babies showed those born into regions where levels were around 80 per cent more likely to have a hole-in-the-heart defect and more than 50 per cent more likely to have a cleft palate.

Their odds of suffering anencephalus – a condition that causes much of the brain, skull and scalp to be missing – were almost doubled, the journal Environmental Health reports.

While birth defects are rare – occurring in about 2 per cent of births – the three flagged up in the study are among the most common.

It is thought the chemicals may harm the unborn baby directly. Alternatively they may damage the woman’s eggs. Although the study did not prove that the chemicals caused the birth defects, it is not the first to make the link.

Researcher Professor Jouni Jaakkola said: ‘Our findings don’t just add to the evidence that water chlorination may cause birth defects, but suggest that exposure to chlorination byproducts may be responsible for some specific and common defects.

THMs are the products of a chemical reaction between chlorine and organic compounds common in lakes, rivers and reservoirs.

The amount of THMs made during chlorination vary according to where the water comes from and the disinfection process, meaning highly chlorinated water does not necessarily have the highest levels.

Home water filters may not be entirely effective at removing the chemicals and bottled water may also be tainted.

Professor Jaakkola said the solution was for water companies to use disinfection procedures that keep the production of THMs to a minimum.

He said: ‘Water disinfection has an important purpose in reducing microbial load and reducing acute gastro-intestinal infections.

‘Some have claimed it is the best public health measure ever introduced.

‘We are talking about rare health effects and a modest risk increase.

‘I don’t suggest stopping using tap water but we have to be conscious that at population level some risks may be related to increased levels.’

The Drinking Water Inspectorate, which is tasked by the Government to monitor the safety of tap water, said its own, larger-scale research had failed to find a link between THMs and birth defects.

Principal inspector Sue Pennison said: ‘Obviously we will review this research, engage our health expert colleagues, and look to see if it means we need to do anything more. But there’s no reason for people to be worried.

‘Chlorination is reliable and has been used for centuries. The only reason diseases like cholera and typhoid are not in our water supply is because of chlorination.’

The water industry trade body, Water UK, said it would consider the findings but chlorination in the UK meets World Health Organisation guidelines. ( source )

Testing for Disinfection Byproducts?

There are no ‘simple’ ways to test for disinfectionm byproducts (DBP’s), but homeowners can find out if the water supplied by their public water systems possibly contains disinfection byproducts by using a test kit like the WaterWorks^TM Free and Total Chlorine Test Kit. See below:

WaterWorks^TM 2 Free and Total Chlorine

The test strips above have two pads: 1 for measuring Free Chlorine Residual and 1 for measuring Total Chlorine Residual.

• No Color on Either Pad: This typically means the water contains no chlorine at all. If on a residential water system, a person may want to re-test and/or consult your local water authority. Please note, though, that the absence of free and total chlorine does NOT necessarily mean the water does not contain disinfection byproducts. A possibility exists that all of the chlorine (or chloramines) added at the water treatment plant have left the water before getting to where it was drawn for testing.
• Color on Both Pads: This means both free and total chlorine exist in the sample water and a possibility exists that the water also contains disinfection byproducts.
• Color on Free Chlorine Pad Only: This should not ever happen because the total chlorine concentration represents the sum of the free chlorine plus the combined chlorine in the water. You cannot have free chlorine registering w/o it also registering as part the total chlorine concentration.
• Color on Total Chlorine Pad Only: If the public water system uses a chlorine/ammonia based disinfectant system then the water will more than likely NOT contain disinfection byproducts. If, however, the public water system uses a free chlorine residual as its disinfectant, then a good chance exists that the water contains disinfection byproducts.

Don’t forget that you can always find out definitively whether or not your tap water contains disinfection byproducts by simply calling your local water company and asking questions. As a general rule, the law requires them to divulge that sort of information upon request to anyone who asks.

Determining the Chlorination System Your Water Supplier Uses

Chlorine Smell Test: In general, water containing only chloramines gives off a much more objectionable odor than water containing a free chlorine residual. While true that a free chlorine system generates chloramines as the free chlorine gets used up fighting whatever biological contaminants it encounters, the amount of odor given off by those chloramines will typically not surpass the amount of odor given off by water treated solely with chloramines.

Home Water Testing: While no test strip exists to check JUST the chloramine concentration in water, one does exist to check both the Free Chlorine Residual and the Total Chlorine Residual: The WaterWorks^tm 2 Free & Total Chlorine Strip accurately measures both parameters with a single water quality test strip.

WaterWorks^tm 2 Free and Total Chlorine Home Water Test Kit

• If the free chlorine test area shows color AND the total chlorine test area shows color, then your water supplier most likely uses free chlorine as its primary disinfectant.

• If the free chlorine test area does not show color BUT the total chlorine test area does not show color, then your water supplier most likely uses chloramines as its primary disinfectant.

Although the above testing method will yield quality results, calling your local water supplier will get you the same information.

Should you wish to test for the presence of just free chlorine or just total chlorine in drinking water, the following simple test strips will yield fast, accurate and reliable results in under a minute:

• Total Chlorine Test Strip (480010)
• Free Chlorine Test Strip (481026)
