Boron contamination in groundwater, any solution?

Feel free to talk about anything that you want.

It is interesting that the majority of the boron contamination has concentrated in the South, what is up with that? :lol:


A heuristic test for Boron is to observe the predominance of arthropods. Boron, being highly toxic to these spineless creatures, is least concentrated where arthropods prevail. :D

So what you are saying that the South is mostly spineless creatures? You know, that totally makes sense! :D

My tuppence worth... with a falling water-table 200m is not unusual to find water... and to those who ask about licenses, suspect most of the wells in CY don't have them. From the environmental perspective, not a prob, as long as the waste-water goes back to ground after use. We ain't talking watering golf-courses with huge amounts of wasted evaporation.

No one drilling for water should expect (sure G100 didn't) to find potable water... and don't forget local knowledge, neighbours will know how deep the table is, and what kind of water is likely to be found (if any).

Be realistic about the uses any water found can be put to and always get it analysed. For watering it may be the case that it won't be suitable for soft fruits or for market garden crops, but it will be suitable for ornamental trees like pethkous or grey water uses such as flushing toilets, and perhaps washing laundry and showering. The analyst will advise.

Then, as so often, look to other sources to supplement your natural source, so think about shipping in potable water for cooking with a man and a tanker truck, who can pump it up to the water tank.

Boron in Cyprus is mostly due to natural geothermal activity. Humans contribute with the added boron found into detergents & untreated sewage. In addition, excessive pumping of groundwater leads to seawater creeping into the aquifers.

Boron can be toxic at very low concentration levels. Boron concentration lower than 1mg/L is essential for plant development, but higher levels can cause problems in sensitive plants. Most plants exhibit toxicity problems when the concentration of boron exceeds 2mg/L

Very sensitive <0.5 Blackberry
Sensitive 0.5-1.0 Peach, cherry, plum, grape, cowpea, onion, garlic, sweet, potato, wheat, barley, sunflower, sesame, strawberry
Moderately sensitive 1.0-2.0 Red pepper, pea, carrot, radish, potato, cucumber
Moderately tolerant 2.0-4.0 Lettuce, cabbage, celery, turnip, oat, corn, artichoke, tobacco, mustard, squash
Tolerant 4.0-6.0 Tomato, alfalfa, purple, parsley, sugar-beet
Very tolerant 6.0-15.0 Asparagus

The numbers above suggest we always test our irrigation water to avoid surprises...

One thing is for sure. Never drink or cook using Cypriot groundwater... you are asking for trouble. Even if the well was tested & found safe, testing should be ongoing (every 6 months to make sure).

I got a few PM's from people who had no idea this problem existed. Well, the rule of thumb is... test & test again if you are on a well. Better safe than sorry.

Thats odd, because I thought the spineless creatures in the South were all about Kleftiko :lol:

Are there any quick and easy test kits for Boron?

Found more info of boron levels in Cyprus. Apparently most of the boron is found on the south part of the island.

Please see page 4. Find out what are the boron levels in your area!

It's all that shitty bog roll that goes to the landfill because they cannot flush it!
