While Bizz Dev Sofie was networking and enjoying the drinks and events at Pollutec Expo in Lyon last week, TRAQUA's hydrogeologists didn't sit still.

Quite the contrary!

They spent a whole week doing fieldwork for four different projects!

Les essais de traçage au traceur en hydrogéologie ne sont pas réservés aux systèmes karstiques ou à des fins environnementales. Nous sommes actifs dans des domaines qui vont bien au-delà. De l'exploitation minière à la géothermie, en passant par la construction de tunnels.

Although remediation is ongoing, there is still debate about the extent of the contamination and how effective the methods are. While the remaining community of Hinkley continues to be engaged, organising public meetings and independent monitoring, the town is now largely abandoned.

The contamination had a catastrophic impact on the groundwater, making it unsafe to drink and causing long-term environmental damage. The plume continues to spread, and some wells still exceed safety standard for chromium-6 by up to 2.500 times.

Due to the size of the plume and the difficulty of reducing chromium levels to natural background levels, the remediation is expected to take decades.

PG&E was legally required to clean up the contamination and has spent over $750 million on remediation. This has included pumping ethanol into the ground to convert toxic chromium-6, planting alfalfa to help absorb the chemical and constructing barriers to contain the contamination plume.

Erin Brockovich played a crucial role in exposing the contamination of the groundwater in Hinkley and holding PG&E accountable. Despite having no formal legal training, she collected evidence showing that PG&E was aware of the contamination and its carcinogenic impact on the local population.

By 2013, the plume had grown to approximately ten kilometres long and three kilometres wide. Chromium-6 levels far exceed safe limits and pose serious health risks, including cancer, to local residents.

Between 1952 and 1966, the Pacific Gas and Electric Company (PG&E) dumped approximately 1.4 billion litres of chromium-6-contaminated wastewater into unlined ponds in Hinkley, California. This toxic chemical seeped into the groundwater and created a massive plume of contamination.

Check this out! Seismology education software, free 🧪⚒️ #geosciences

It’s #earthscienceweek so I thought I’d go into a bit more detail on how educators can use to our Quick Quake tool to demonstrate how @earthquakes.au seismologists quickly calculate the location and magnitude of an earthquake. It works on macOS machines with Apple Silicon too.

Oh, cool! Thanks, @kinarnicholas.bsky.social, for highlighting my article as Hydrology Paper of the Day!

Hydrology Paper of the Day @ericagies.bsky.social on how changes in air moisture are related to climate change and a discrepancy in dryland regions: for some areas, models do not adequately capture decreases in humidity; linkages with fires and ecosystem services; and the need for realistic models.

Do plants affect global climate through water? Some climate scientists say yes, but others say plants' effect is only local or regional. If the plant-power proponents are right, it means, to solve climate, we need more than the energy transition. We also need to restore land to health. My story:

The number of students choosing a STEM training are decreasing, so let's show how exciting it is to work in this field! 😍

Happening this weekend in Brussels at @Tour & Taxis!

@dailysciencebe.bsky.social est incontournable pour la communauté francophone intéressée par les sciences. Ses articles bien documentés constituent une excellente alternative au « journalisme fastfood » et aux « absurdités de ChatGPT » qui inondent aujourd'hui l'Internet.

Bizz dev Sofie enjoying a break at the stand of Cluster H2O at Lyon Expo Pollutec.

After paying a visit to 26 exhibitors in the geotechnical, environmental, and geothermal domains and talking about our expertise in hydrogeology and fluorescent dye tracing it's time for some rest.

I have so much respect for Greta Thunberg because she easily could have coasted on speaking gigs and Davos appearances for the rest of her life

Dr. Jane Goodall filmed an interview with Netflix in March 2025 that she understood would only be released after her death.
