The groynes along Denmark's west coast are numbered, and number 42 looks exactly like the ones on either side of it — a low line of stone running out into grey surf, doing its patient work against the sand. Nothing marks it. But behind the beach, under the dunes of Harboøre Tange, sits one of the worst chemical contamination sites in Denmark: something over a hundred tonnes of pesticide waste, buried between 1957 and 1962 and sitting a few metres from the North Sea ever since. The company that put most of it there was Cheminova, whose plant still runs two kilometres up the spit at Rønland. Cleaning up Høfde 42 has taken longer than the dumping did, by a factor of ten.

Neighbours and the local authority complained about what the plant's wastewater was doing to the water environment, and by 1953 Cheminova was looking for somewhere with fewer neighbours. It found Harboøre Tange: a sandspit roughly ten kilometres long, stru...

Cheminova: What Went Into the Dunes

Photo credit Beethoven9, CC BY-SA 4.0. Høfde 42 was a municipal chemical waste dump, and between 1957 and 1962 Cheminova used it heavily. The permit covered three types of waste. What actually went into the dunes and the sea, according to later accounting, was more than a hundred different substances, solid and liquid...

Cheminova: The Fisherman and the Gulls

Sat, 05 Sep 2026 00:00:00 GMT

A local fisherman known as Rav-Aage started noticing dead fish and sick gulls, and kept saying so. Biology students from Aarhus University took up the work and gave the complaints the weight of measurement. It took years, and t...

Region Midtjylland put the cost of removing the ground contamination at Høfde 42 at a quarter of a billion kroner in 2014 — the same year that the American FMC Corporation bought Cheminova outright for roughly 8.5 billion kroner from Auriga Industries, which had held the company ...
