Any guidelines or sugggestions on testing that would be required to assess safety - what substances, what detection limits, how often?
The toxicity of produced water depends on a number of factors, among them:
--what's used to produce it (what's injected) and how
--the chemical profile of the coal
--the geology of the production area
--the size and flow of the body of water into which it's discharged
These are just a few. Produced water in offshore exploration is can be quite saline with higher mineral content, therefore heavier, than the surrounding water. It can contain solubility levels of the petrochemicals with which it's in contact. Consequently, its discharge can affect benthic biota.
Guess the answer would be that more information is needed before attempting to answer the question. Hope that helped,
