I can’t wait until that stuff seeps into the groundwater.  

For commercial properties, former dry cleaners can be very problematic. has property always been connected to public sewer or did it use septic system that can discharge pollutants into groundwater. 

Each apartment has one full bath and one kitchen sink, no dishwashers or clothes washers provided (though at least one tenant has a portable clothes washer.)My calculations with the 47 degree groundwater in Michigan lead me to believe that a single 199k btu system, the largest I can feasibly and affordably find, may not be enough to support 4 showers and 8 sinks, even with water savers applied.

And Jay Hinrichs the main reason I would see in scoping a new sewer line like that is it is very common to get what they call a belly in a sewer line which is where the ground underneath sinks in one area causing essentially a low spot and can be very common due the so much change in the ground on a new construction and only wound take one rain or some ground water.

Once Rain hits the ground/water bodies, it is no longer Rain, it isRising Flood Waters. 

I've seen people who have bought properties with net negative values due to soil and groundwater contamination.  

Depending on the type and extent of the contamination there are some allowances for simply leaving it in place, monitoring and/or pumping groundwater and treating that in-lieu of full removal/remediation.

The obligation of Lessee shall indude the repair or any damage occasioned by the installation, maintenance or removal of Lessee's Tra e Fixtures, furnishings, equipment, and Lessee-Owned Alterations and Utility lnslallations, as well as the removal of any storage tank installed by or for lessee, nd the removal, replacement, or remediation of any soil, material or ground water contaminated by Lessee, all os may then be required by Applicable Requirom nts and/or good practice. lessee's Trade Fixtures shall remain the property of lessee and shall be removed by lessee subject to its obligalion to repair and resto o tho Premises per this Lease.Actually I just cut and copied this from the lease (OCR so the text came out poor) it looks like they get to keep their trade fixures.

Is the moisture coming from vents or ground water? 

Also their population has grown by almost 50% since 2000http://www.city-data.com/city/Bakersfield-Californ...I know that some areas in the central valley have experienced literal sinking due to pulling too much groundwater out of the ground though.
