Last week came a new report that attempts to take earlier economic impact analyses of the frac sand industry down a peg or two. Read the story, by our frac sand beat reporter Kate Prengaman.

While you’re at it, check out — and bookmark — our newly designed frac sand project page.

There, you’ll find a much-requested new update to our frac sand map, along with a downloadable list of sites, produced by Prengaman.

It also has links to all of our frac sand coverage, explainers, reports, videos and photos.
