We note, however, that while public perceptions of river water quality could guide water management policies, scientific measurements of water quality must not be replaced with stakeholder perceptions. This is because aspects such as ecological integrity may not be important to segments of the public...
The cost for monitoring water quality varies across the spectrum of devices, systems and industries and the environment within which the monitoring is being carried out. However, the environmental costs, as well as legal, corporate and social responsibility, make the efficient monitoring of water an...

Ground-water quality undisturbed by mining is often worse than New Mexico standards and data are needed to help establish closure requirements. The key to determining pre-mining conditions was to study the hydrogeochemistry of a proximal natural analog site, the Straight Creek catchment. Main rock ...
