Oil mixed with borewell water from compressor

We have borewell compressor in our home, Few weeks before accidentally due to oil seal problem compresdor oil was mixed with ground water. Once we identified the issue we fixed it by calling a motor mechanic. But still we are getting oil mixed water even after one week from the issue is been fixed, The mechanic says the water will be clear once all the leaked oil come out from the bore. Please suggest will it be resolved over time or we need to do anything…
