Why should I care about wellfields? Am I located in a wellfield? How does this affect me in the medical/laboratory business? What are medical/laboratory contaminants? Is more required of my facility if it’s in a wellfield? What can I do at my facility to help protect groundwater? Where can I get more information?

Why should I care about a wellfield?

For many years we believed that our groundwater was protected from contamination by being underground.  We now know that substances on the surface can seep down and contaminate our drinking water supply.

How does this affect me in the medical/laboratory business?

1)   If you are careful to contain your contaminants, you will avoid polluting your site and avoid a potentially expensive clean-up down the road. 

2)   Voluntary action now will avoid the need for government regulations.

3)   Being a good neighbor in your wellfield is good for your business – it will be appreciated by your customers.

What are medical/laboratory contaminants?

In the medical/laboratory business, processing and stabilizing chemicals may be the most obvious contaminants.   But cleaning solutions, solvents, degreasers, and underground fuel oil tanks are also of concern if they are not properly used or stored.

Is more required of my facility if it’s in a wellfield?

NO.  You’re not currently required by regulations to do any more than businesses outside the wellfield do, BUT like all businesses, those within the wellfield are encouraged to keep contaminants from being spilled or poured on the ground.  (For building or improvement permits, the Indps. Dept. of Metropolitan Development can help you with special permit regulations.)

What can I do at my facility to help protect groundwater?

There are several easy things you can do to help prevent groundwater contamination:

·         If you have underground fuel oil tank, upgrade it to meet federal and state requirements.  Optimally, a monitoring system should be installed to warn of any potential leakage.

·         If possible, install secondary containment around your xylene stills, hazardous waste storage area, and even the area in which cleaning and maintenance supplies are kept.

·         Close and seal floor drains near chemical storage and usage areas.  Use an epoxy floor sealer in areas which chemicals are used or stored.

·         Clean-up minor spills (up to 7 gallons) with absorbent materials.  Train all employees on spill prevention and containment.

·         Do not dispose of any cleaners, solvents, paint thinners, or reprocessing chemicals in your dumpster.  Ensure custodial and grounds personnel are trained in the proper use and disposal of the chemicals they use.  Unused and waste products should never be poured on the ground.  Use a hazardous waste hauler or use the Indianapolis Tox-Drop sites for small quantities.
