Construction in the Swamp

Despite the miserable weather and ongoing rain, we constructed a wooden structure to hold the GPS receivers, solar panels and other electronic equipment between the three wells. We worked out how and where to mount the antennas and had parts made to accomplish it. Although I had to leave before it was completed, the team persevered through the storm and now we will be monitoring ground subsidence and sediment compaction in the Mississippi Delta.

Report Charges ‘Nepotism and Neglect’ on Bangladesh Arsenic Poisoning

Two decades after arsenic was found to be contaminating drinking water across Bangladesh, tens of millions of people are still exposed to the deadly chemical. Now a new report from the group Human Rights Watch charges that the Bangladesh government “is failing to adequately respond” to the issue, and that political favoritism and neglect have corrupted the government’s efforts.

The Growing Groundwater Crisis

Groundwater is being depleted at alarming rates, not only in drought-stricken California, but around the world. When groundwater is depleted, it can take tens to hundreds of years to for it to reestablish its sustainable level, if at all. What can be done to avert a water crisis?

Hospitalizations Increase Near Fracking Sites, Study Shows

People living in areas of Pennsylvania where hydraulic fracturing is booming are suffering increasing rates of hospitalization, a new study says. The study is one of a small but growing number suggesting that the practice could be affecting human health.

Subsurface Discovery Sprouts a New Branch on the Tree of Life

Last week a study published in Nature pulled the veil on a branch of the bacterial tree of life that has evaded detection for nearly a century and a half. The study used cutting edge genome sequencing and savvy bioinformatics techniques to make this remarkable discovery.

The liberal use of water for irrigation by farmers cultivating rice is contributing to a rapid drop in groundwater levels In the northern Indian state of Haryana.

Overuse of Water by Indian Farmers Threatens Supply

Convincing farmers that it’s worth it to reduce their water consumption will rest on our ability to help develop local groups to manage aquifers at the community-level.

Geology and Filming in Mizoram

In the small town of Kolasib, we stayed in Hotel Cloud 9. I had been told since I was a child that I was always off on Cloud 9 and now I was actually here. However, the electricity wasn’t for the first few hours, so showers were cold, but the dinner was hot.

Tiger pugmarks (footprints) in the tidal channel.  Our guide estimated 5-6 hours old.

Tiger Footprints and Dhaka

We finished our time in the Sundarbans with a silent boat ride in a tidal creek. The highlight was sets of fresh tiger footprints. We then had a long sail back to Dhaka with only one stop at a village. We then had a whirlwind tour of Old Dhaka with enough shopping to send the students back happy.
