Guests admiring the postcard-like views of Lake Lucerne, Lake Thun or Lake Neuchâtel could also be stunned to find what lies beneath these pristine alpine waters.
For years, the Swiss army has used the lakes as a dumping floor for outdated munitions, believing they could possibly be safely disposed of there.
There are an estimated 3,300 tons of munitions in Lake Lucerne alone and 4,500 tons within the waters of Neuchâtel, the place the Swiss Air Power has been conducting bombing workouts till 2021.
A number of the munitions have been situated at depths of 150 to 220 meters, however different munitions in Lake Neuchâtel have been solely six or seven meters under the floor.
Now, the Swiss Ministry of Protection Provide 50,000 francs (£45,000) prize for the perfect concept.
The very best three concepts for protected, environmentally pleasant ammunition restoration options will share the prize, however the salvage operation is predicted to value billions of {dollars}.
double jeopardy
The truth that so many bullets have been dumped into Swiss lakes – Brienz was certainly one of them – has been recognized for many years, though questions on security have just lately been raised.
Marcos Buser, a retired Swiss geologist who advises the federal government on the topic, wrote a analysis paper a decade in the past warning of the hazards of dumps.
These munitions pose two dangers, he stated. First, regardless that it was underwater, there was nonetheless a threat of exploding as a result of in lots of instances “the army didn’t take away the fuse earlier than dumping the ammunition.”
Then there’s water and soil air pollution – extremely poisonous TNT is prone to contaminate lake water and sediments.
The Swiss authorities admits that elements comparable to poor visibility, magnets and the load of particular person ammunition “pose important challenges for environmentally pleasant ammunition recycling”.
A 2005 evaluation of potential restoration applied sciences confirmed that every one proposed options for ammunition restoration pose critical dangers to the lake’s delicate ecosystem.
Historical past of the issue

This is not the primary time the Swiss army has seemed to be negligent on the subject of ammunition.
alpine village Mitholz hit by big explosion In 1947, 3,000 tons of ammunition saved by the military on a hill overlooking the village exploded.
9 individuals have been killed and the village was destroyed. Explosions might even be heard in Zurich, 160 kilometers (100 miles) away.
Three years in the past, the army revealed that 3,500 tons of unexploded bombs buried within the mountains have been unsafe in any case and stated they might be eliminated.
For Mitholz residents, this meant being away from residence for as much as ten years whereas the cleanup befell.
There have additionally been scandals over impartial Switzerland’s Chilly Warfare protection technique of mining bridges and tunnels to chase away invasion. Some bridges have to be demined rapidly as a result of threat of explosions attributable to trendy heavy items autos.
In 2001, a hearth broke out within the Gotthard Tunnel, certainly one of Europe’s predominant north-south transport routes, when two vans collided, killing 11 individuals.
A considerable amount of explosives (not concerned within the fireplace) have been nonetheless saved in a warehouse close to the doorway of the tunnel, and after firefighters efficiently extinguished the blaze, the military arrived with bomb disposal tools available.
This week, the army revealed that stories of civilians discovering unexploded bombs within the Swiss countryside elevated by 12% final yr (2022).
Even on glaciers which can be retreating underneath the affect of local weather change, melting ice is exposing spent and reside ammunition from decades-old alpine coaching.
That is the legacy of Switzerland’s “armed neutrality” protection technique – sustaining a big militia (army service is obligatory for all Swiss males) and coaching the army nearly completely within the densely populated nation.

Time-consuming and expensive
The duty of clearing munitions from Swiss lakes is predicted to be lengthy and sophisticated. However first, somebody must give you a workable plan on precisely learn how to get them out.
Though some complain that the army ought to take this into consideration when dumping waste, geologists have suggested the army for many years that the follow is protected.
On the lookout for an answer. Following a name from the Swiss Protection Ministry, the general public can submit their concepts till February subsequent yr, when a panel of consultants will evaluation them anonymously.
The three winners shall be introduced subsequent April.
“There are not any fast plans to implement the submitted entries, however they might function a foundation for additional clarification or the initiation of analysis tasks,” the federal government stated.
Mr Busser advised in search of recommendation from the UK, Norway or Denmark their expertise Disposal of wartime particles containing unexploded ordnance.
So will he provide any concepts? “No, I am too outdated now…but when they want any recommendation, I will be pleased to provide it.”
