    Irrigation Water Quality for Agriculture

    With growing demands for water that is suitable for drinking (potable) and expanding irrigated acreage, there is an increased pressure on irrigated farms to consider using nonpotable alternatives. However, low quality irrigation water can adversely affect soil physical conditions and crop production. This resource provides in-depth information on the importance of irrigation water quality, water quality attributes, salts content, toxicity and the sources of toxic components, and bacteria in water sources.

    Understanding How Data Centers Impact Surface and Ground Waters

    This resource addresses some general concerns and questions about how data center operations could alter water availability and affect the quality of our shared surface water, underground water, and public water systems. The extensive demands for cloud storage, streaming services, and artificial intelligence (AI) in today’s digital economy has sparked a massive boom in the establishment of data centers. Although the concerns and public discussion around this are primarily focused on the huge electricity demands of the data centers, they also have a significant localized impact on our water resources.
