You need to replace the washer on the stem. It's a Delta so it's possible that you have the type where the washer is actually in the very bottom of the manifold instead of on the stem.

Pry the hot/cold button off the top of the handle. Make sure the water is turned off below the sink.

Under the button should be screws. Remove the screws. Pry the handle off. Remove the stems by lifting then out.

That should give you access to the washers you need to change.

Take a rag and put over nut then tap all-around nut. Then use your hand to try and unscrew. A strap wrench is the best tool for taking these off. I have been to so many of these where the homeowners have used channel locks or pipe wrenches and scarred up nut or broken off copper tubes. They seem amazed when i tap it a few times and remove it with my hands. Channel locks and pipe wrenches actually cause the nut to bind when using this much force. Make sure you loosen the plastic retainer on top of the nut first.For more details about single faucet repair

You should get the yearly report the water company must produce on the composition of your water and analyze it. You may want to have the water in your home testes to see if it has the same percentage of H2S that they are reporting. You can remove some of it by Carbon Filtration but you would have to speak to a local water treatment company.
