Semi-annual groundwater sampling is conducted at a petroleum facility in northern Kentucky. The site is situated on a very steep slope along the banks of the Ohio River. A near miss occurred in October 2006 when technicians were emptying a 325-gallon polytank containing purge water into an oil/water separator. A technician was lifting the tank to get the last few gallons of purge water out of the tank when the tank slipped and fell out of the truck bed, almost hitting a second technician. A root cause analysis was conducted and it brought to light the inherent risks associated with moving large volumes of water around the site. It was decided to use an alternative sampling technique (a no-purge sampling device called a HydraSleeve) to eliminate the generation of purge water, which in turn eliminated the safety concerns with hauling the purge water around the site. No-purge sampling has been shown to produce comparable results to standard purge and sample techniques for certain constituents. As an additional benefit, no-purge sampling has reduced the amount of time to conduct the sampling— from about 4-5 days to about 2 days; thereby also reducing the costs. Thus, an increased concern for safety doesn't have to lead to an increased cost.
