The Natural Pozzolan Association will stage its first official industry gathering May 16-17 at Rancho de los Caballeros, a Wickenburg, Ariz., ranch about an hour from Sky Harbor International Airport, Phoenix. The Natural Pozzolan Symposium will open with afternoon presentations followed by evening reception, and presentations continuing the next morning. Attendees will have the option of a May 17 afternoon visit to a natural pozzolan deposit near Skull Valley, Ariz.

Kirkland Mining is among producers whose 2018-19 ramp up will see an NPA-estimated 1 million tons of new natural pozzolan capacity geared to North American concrete producers. — www.pozzolan.org

With overall public spending on water utilities declining year-over-year in five of the last 10 years, core federal programs are proving to be more critical in addressing investment needs in urban and rural treatment systems and networks, according to water market-wise Bluefield Research.
