(University of Maryland), Owen, J.S.Jr. (Virginia Polytechnic Institute and State University) , Oki, L.R. (University of California Davis)

Water quality and water quantity are major concerns for growers around the world.  There are number of factors that can impact irrigation water for plant production including policy, changing weather patterns, aquifer depletion, and saltwater intrusion.  This article discusses a number of aspects of water use, capture, remediation, and reuse for specialty crop production.  Various techniques and equipment for the removal of sediment, pathogens, agrichemicals and other contaminants are discussed.  Remediation technologies reviewed include filtration (for example: rapid sand, slow sand, membranes, and filter socks), activated carbon, disinfection (chlorine, ozonation, UV), and biological control (constructed wetlands, vegetated buffers, bioreactors).

The Cost of Filtration

Raudales, R. (University of Connecticut), Fisher, P. (University of Florida), Hall, C.(Texas A&M University)

Filtration is an important step in capture and re-use of irrigation water.  This article presents filtration systems, the initial cost, and the cost to treat 1,000 gallons of water.  Filtration is the first article in the three-part series of water management in GPN magazine. 

The Cost of Filtration (1) can be found in the link bellow.

Slow sand filters have been shown to remove pythiacious organisms from captured runoff water.  In this study, Tobacco Mosaic Virus (TMV) was regularly added to irrigation runoff water.  The virus passed through the sand filters for approximately 5 weeks, but gradually reduced to undetectable virus titer using ELISA during week 6 to 9.  This is the first report that showed slow sand filters removed TMV from runoff water.
