I would like to determine naphthalene concentration in water for a wastewater treatment project. Would it be possible to use chromatography technique or would you suggest something else?
There's a paper on determination by GC http://link.springer.com/article/10.1007%2FBF01243141#page-2
In water I suggest the HS SPME. The analytes are adsorbed from the headspace of a small vial on a PDMS (in your case should suit) fiber. Then the desorption happens directly in the ijection inlet of your GC.. Is more rapid because you don't need a cleanup procedure and quite accurate, I attach one of the papers you can find in the literature.

you can find also others

For naphtalene, I would use SPME inmersed in water, because the volatility of the analyte is not very high. Also, you could use SPE or stir bar extraction.
The actual analysis should be performed using GC-MS
I also agree with Jhon. It depends on how dirty is your sample. WIth HS you have a more clean chromatogram but a little decrease in sensitivity. I suggest you to try both. If using HS you should heat the sample and saturate the sample with NaCl. Of course you need a GC-MS
Depending on your application desired detection limits and interferents present you may find Synchronous fluoresence scanning (SFS) will provide you with the necessary information with little of no sample preparation - an advantage given the volatility of naphthalene
