Bonfol (French pronunciation: [bɔ̃fɔl]) is a former municipality in the district of Porrentruy in the canton of Jura in Switzerland. It was also home to one of the most hazardous waste landfills in all of Switzerland.

Bonfol is first mentioned in 1136 as Bunfol. The municipality was formerly known by its German name Pumpfel, however, that name is no longer used.^[3] According to tradition, the village was founded after the Burgundian Wars for Stephan of Hagenbach, a vassal of Charles the Bold, to replace his destroyed villages of Bonfol-le-Vieux, Trunchéré and Vareroille.

During World War I from 1914 until 1918, the Western Front between the Allies and Germany began at the village of Le Largin in Bonfol.^[3] On 1 January 2024, Bonfol is set to merge with Beurnevésin to form the new municipality of Basse-Vendline.^[4]

Bonfol has an area of 13.58 km² (5.24 sq mi).^[5] Of this area, 6.4 km² (2.5 sq mi) or 47.2% is used for agricultural purposes, while 5.96 km² (2.30 sq mi) or 43.9% is forested. Of the rest of the land, 0.94 km² (0.36 sq mi) or 6.9% is settled (buildings or roads), 0.2 km² (0.077 sq mi) or 1.5% is either rivers or lakes and 0.07 km² (17 acres) or 0.5% is unproductive land.^[6]

Of the built up area, housing and buildings made up 2.9% and transportation infrastructure made up 2.3%. Out of the forested land, all of the forested land area is covered with heavy forests. Of the agricultural land, 35.4% is used for growing crops and 11.6% is pastures. All the water in the municipality is in lakes.^[6]

The municipality is located in the Porrentruy district, in the north-east corner of the Ajoie region on the border with France.

The nature preserve Etangs de Bonfol is located close to the village.

Beginning in 1961 many of the largest pharmaceutical and chemical companies in and around Basel began burying chemical waste in a former clay mine outside the village. Eight of the largest, including BASF, Novartis, Roche and Syngenta, formed Basler Chemischen Industrie (BCI) to administer the site. The Bonfol dump remained in operation until 1976 and over those fifteen years about 114,000 tonnes (112,000 long tons; 126,000 short tons) of chemicals were dumped.^[7] After it was closed BCI believed the clay would hold the waste in place. The dump was buried and the 20,000 square meters (4.9 acres) of land that it covered was replanted. However, in 1981 the first leaks were detected from the dump and from 1986 through 1995 BCI installed a drainage system and built a runoff treatment plant. After protests by Greenpeace and the passage of Switzerland’s Federal Ordinance on the Contaminated Sites in 1998, on 17 October 2000 BCI signed an agreement with the Canton to fully excavate and clean the entire dump.^[8]

In 2007 construction began on an excavation hall that covered the entire site. Using a large overhead crane and digging bucket up to 160 tonnes (160 long tons; 180 short tons) of contaminated earth was excavated per day. It was then loaded on sealed rail cars and taken to incinerators in Germany where it was burned at temperatures up to 1,200 °C (2,190 °F) and turned into chemically stable ash. In July 2010 some of the chemicals in the dump exploded during excavation. One machinist suffered minor injuries and the project paused for several months to evaluate the hazard.^[8] At the end of August 2016 the last of the contaminated soil was removed, bringing the total removed and incinerated to 202,200 tonnes (199,000 long tons; 222,900 short tons). The project cost BCI a total of SFr 380 million.^[9]
