Phosphorus and groundwater: Establishing links between agricultural use and transport to streams [More info]
Explains why phosphorus is important, how it moves through the terrestrial water system, how we measure it, and what this means for people who need to manage or monitor human activities that produce it.
Produced waters database [More info]
Database provides information on petroleum reservoirs, type and abundance of constituents dissolved in produced water, geochemical reactions between the water and rock, hydrology and geologic, spatial distribution of petroleum production areas.
