Look for our crews at Robinson Terminal North over the next several weeks.

RiverRenew will be collecting soil samples at Robinson Terminal North, beginning the week of July 1, 2019. This data will be used to better understand the conditions below ground to design and build solutions that are best suited to our local geology. When we’re done collecting samples, we’ll follow standard practice and fill the holes with an environmentally friendly grout-like material and return the site to its existing condition.


Please contact the RiverRenew Communications and Outreach Team at or 703-518-6030.

More Boring Details

What, exactly, is a boring?

A boring is essentially a small, deep hole in the ground – about the diameter of a softball. We’ll conduct borings to collect two types of soil samples:

Auger sample: Think of a long drill bit going into the ground.

Split-spoon sample: Think of a hollow straw being pushed into piece of cake.

What will I see?

You may see drilling equipment, or “drill rigs,” with three-or four-person teams at the locations outlined on the map. The equipment will move from location to location and spend approximately 2 weeks at each site, weather permitting. Please note, boring locations have been chosen with the intent of posing minimal disruptions to the community, but some locations may require temporary changes in pedestrian and traffic patterns. We will notify you of any changes in traffic conditions, and we apologize in advance for any inconvenience!

Can I watch?

Of course! But please keep a safe distance from all equipment/workers and be mindful of your surroundings.

Will it be noisy?

Kind of. Think of a DASH bus idling and pulling away from a stop. Please note that we’ll only be working during the hours of 7:00 a.m. and 6:00 p.m.

Will it smell?

Likely not. Soils pulled from the ground will pretty much smell like dirt.

When will it happen?

We’ll be drilling on weekdays between 7:00 a.m. and 6:00 p.m.

Is it safe?

Yes. These types of investigations are very common in Alexandria, and our crews are trained to perform this type of work.
