In the Yakima Valley, WA, with its 500,000 irrigated acres and its network of leaking canals, irrigation induced seasonal wetlands are common. In the floodplain, upwelling hyporheic / phreatic river water can be masked by irrigation induced hydrology, but only while the canals are full, or recently so. During this January visit, long after irrigation diversions have ceased, there was no mistaking the dominant river-induced groundwater hydrology at the site.

Renewed soil science licensing efforts are underway in Washington State. Supporting them is a new website. Titled Soil Science Licensing, the site is available to become a clearinghouse for all soil science licensing efforts. It links to the best available information, including the list of soil science licensing boards maintained by the Soil WikiProject.

Salt load in land applied waste water is considered by many to be the single most important challenge facing the industries which use land application to treat waste water. Particularly sensitive to this issue are briners, cheese processors and some electronics manufacturers. Among waste water spray field management advisers the consensus is that saline waste water spray field operations should avoid sites where the discharge can't be diluted by substantial rainfall and/or groundwater flux. In short, dilution is the only practical solution when it comes to salts in waste water.
