@Dennis M. you do know the poison leeches into the ground water which someone might end up drinking right.

EPA has completed removal of hexavalent chromium from thirteen basements and installed systems to prevent further infiltration of contaminated groundwater.

He probably has a leak, we're at the top of the Palisades so groundwater is unlikely.

Jermaine here wow that price is very high in my opinion, Last year we took a long look at building two six unit building, the city had so much red tape,from commercial water,adding a additional transformer, ground water runoff, and that is not even the stuff for the building, just thinking about it I have a headache.We just bought one.

I am by no means an expert, but if it's never flooded in the past, I'd thing maybe it's not a groundwater problem, but something involving drainage.

Worst of all, it was ground water--coming up from underneath the slab, and there was no easy way to stop the flooding.Adding insult to injury was the fact that this was the third time in six monthsthe house had flooded.

I was told the ones in closest proximity to the house are to be "capped" by the end of the year, but I would like to verify that myself.The property is connected to city water, so I guess the issue that could arise is whether or not groundwater contamination has or could occur. 

A tenants policy will not cover the damage due to ground water seeping in. 

You are getting ground water vapors at the dirt portion.  

Do you have adequate projection on your eaves - 2’Do you have proper drainage 3/4 crush works best or create a ditch away from the property to collect ground water etc Cracked foundation you could try aqua plug depending on the cracks etc
