You would think that modern technology could pinpoint which house it is coming from, and do something about it.

It was recognized back in the 1980's but back the then the problem was not a contribution as a greenhouse gas but its effect on domestic water wells, both for safety and for use in ordinary household tasks. Also, local farmers had gas which came up from the subsurface killing plants in portions of their fields.
