Leaking fresh water tap

[Uncle D]

Hi, I wonder if someone can help.
We have a multi tap on our kitchen sink, its a mixer for hot/cold with a separate small handle at the base of the tap for fresh water, that is the one that is leaking, it wont turn off properly. I know its probably has some kind of washer, but I haven't changed a washer on these type of taps before and dont even know if it can be done.
Can a leak be fixed on these type of taps or do I need to buy a new tap?
Thanks
