Understanding And Dealing With Water Odour

Smelly Water - Understanding and dealing with foul smelling water

How can odour be controlled in my dam?

Let’s face it, smelly things are never pleasant. A smelly dam can be considered a nuisance for the owners and also for the community as a whole.

Odours can have some very negative consequences as the stench coming from your dam can impact the well-being of those around you, and this is also the most commonly noted reason a smelly dam is reported to authorities. Legal action may be taken against odours detected out side of a property or boundary as it can have an impact on another person’s property value and the health of those who come into contact with it. Don’t freak out just yet though, we have the solution to your pongy woes.

Is the water odour dangerous?

Yes. The most common suspect and health threat is hydrogen sulphide which gives that rotten egg smell. As it is very heavy compared to air, the gas often settles in low enclosed spaces such as man-holes and sewers. Another issue is that even at low concentrations it is highly flammable and extremely toxic making this gas very dangerous. Not only does the gas cause a headache in both the real sense and the emotional sense, at high levels it can also cause fatigue and nausea. If a person suffers from asthma they may have a stronger reaction from exposure to the hydrogen sulphide gas.

Is there a law to manage odour?

Indeed, air is often closely monitored and by law, must meet certain levels.

Section 15a of the Clean Air Act 1961 makes it an offence for odours to be detectable by authorised officers outside premises scheduled under the Act. Scheduled premises are those listed in the Clean Air Act and include fuel burning equipment areas, grinding and milling works, chemical works and a variety of other industries.

How is odour measured?

There are a number of techniques for measuring odour and the unit of measurement used is ppm. As the level creeps up to 0.008ppm, side effects can begin to be experienced such as those previously mentioned and at 2ppm, asthmatics will begin to experience bronchial restriction. Between 5-10ppm, side effects including minor metabolic effects may be experienced and when odour reaches 20ppm, memory loss, vertigo and other neurological effects may occur.

How to treat a smelly dam?

DAZZeL Eco Plus is a concentrated formula designed to obliterate strong odours. This product is a 20:1 ultra-concentrated essential oil complex derived from organic plant leaves and herbs. These bind with the odour causing molecules, breaking them down and neutralising them leaving a clean fragrance which extends as far as 800m! Best of all it is non-toxic, acts quickly and is a long-term solution for odour control.

    I have two dams on my property and they both ran dry for some months we have recently had good rain and they are currently around 75%
    My problem is that from the initial brown water colour it has changed to an unpleasant grey along with an even more unpleasant odor. We have never had this happen in the twenty + years we have been here.
    The dams are minimally stocked with carp, but otherwise are for the local wildlife and reserves in case of fires.
    I’m curious as to whether your product DAZZeL Eco Plus would be suitable for this?
    I would appreciate your advise as well as price and availability in QLD.
    Thanks and Cheers.

      Good Morning Neil,
      Dazzel Eco will help with the odour but the odour is most likely caused by anaerobic bacteria so for better long term solutions you should consider introducing aerobic species of bacteria (Biostim Powder) and installing an aeration system to favour aerobic species rather than odour causing anaerobic species.
