I am trying to come up with ideas for treating (ideally in-situ) a large urea spill. The groundwater has a concentration of 5000mg/L to 15,000mg/L ammonia. One consideration is using vinegar to oxidize the ammonia. Do any of you have experience with this type of treatment? If so, was it successful? Were there air issues?
What about breakpoint chlorination? I assume that would require pump & treat.
Thanks,

My first thought is keep the oxygen up (i.e. air or bio-sparging), and something for a food source, and natural bacteria should have a heyday. I'll think a little more on it though, and maybe someone that has worked with it will have some more ideas. 字串9
What is the depth to the groundwater?
What factors on the surface impact, such as under a building, or in a field?

Not sure what you need the vinegar for. Ammonia is easiliy oxidized using an aerobic treatment process.
Ammonia can also be stripped from water. However, ammonia is considered in some areas to be an air toxic.
Breakpoint chlorination will also work, but it is probably not feasible with the high concentrations of ammonaia that you have. Chlorination will probably not work insitu either.
