Recycling of produced water for subsequent hydraulic fracturing has emerged as an essential technology for economic development of unconventional oil and gas resources. As a result, impoundments for storage of produced water are larger and retention times longer. During impoundment, microbial communities evolve that produce malodorous compounds and alter the fate of metals. Standard industry practices for management of produced water include aeration and biocide amendment, both costly.  The presentation will provide a brief introduction to produced water management and discuss the how bacterial communities change from the make-up water through stimulation and production.  The impact of water management strategies on microbial communities and geochemistry will be discussed in the context of recycling of produced water, emergent strategies for more sustainable hydraulic fracturing, and opportunities for novel chemistry in treatment and microbial control.
