Complete the quest "Helping Havarl’s Scientists", after which talk to Assistant Torvar to update the quest "Turian Ark: Not Dead Yet", then travel to the Turian encampment on Havarl and defeat the Roekaar. After you talk to Avitus Rix that quest will go dormant, but you’ll be able to start up this one, as a sort of consolation. Make your way to the western edge of the camp to find a Turian named Drusa, who wants to reclaim the debris they left scattered across Havarl. Not for any environmental concerns, mind you, but to keep any potential salvage and tech out of alien hands. Practical, and it’s a task well worth pursuing.
There are nine such bit of debris, all of which are marked by navpoints on your map, so it shouldn’t be any trouble for you to wander about and find them. It is, in fact, a perfect sort of quest to attend to while you see to other business, just keep an eye out for the scrap (or its navpoints) as you work on other things. As a bonus, there’s usually a container to loot at each site, and scanning each bit of wreckage is worth some Milky Way Research Data points. When you’ve scanned them all you’ll earn 29 AVP, +2% Havarl viability and 270 XP.
