The 2015 lists of registered water haulers. 

Please Note:  Private Water Systems Water Haulers are registered at the local Health District in which their business is located.  Once the company is registered and their truck is inspected and approved by their 'home' health district, the truck receives a state water hauler registration sticker which allows them to haul water anywhere within the state of Ohio.  The Ohio Department of Health relies on the local health districts who register and inspect the water haulers to provide the information about water haulers they register. If a local health district has not reported to ODH that a water hauler has been registered it will not appear on the list.

Laboratories certified to conduct water testing for private water systems

The private water system rules (Ohio Administrative Code Chapter 3701-28) require water samples collected from private water systems to be analyzed by a certified laboratory for system approval after new construction, alteration or repair. The department recommends that all water samples collected from private water systems for real estate transactions, or consumer information also be analyzed at a certified laboratory to ensure that proper procedures and water analysis methods are used to protect public health.

Laboratories who will perform alternative analysis methods to provide a colony count after a water sample has been invalidated.

Private water system rule 3701-28-03 (S)(1) requires water samples to have a coliform CFU count.  Occasionally, the lab will be unable to provide a result due to the formation of precipitate during the analysis process.  If you have had a water sample result returned as invalidated or unable to report due to the formation of black precipitate you will need to use one of the approved alternative analysis methods for water sample coliform CFU counts.  The link below provides the contact information for certified labs which will perform one of the alternative analysis methods.  Remember these methods are only to be used AFTER a sample has been invalidated by the lab due to the formation of a precipitate.
