LNAPL Correction to water levels

I am having trouble with jobs that have product in wells. We got the lab to do product density so we could work out the SWL corrected to the hydrolic equivalent created as a result of the product.
In ESdat I have entered the TOC, depth to GW and Depth to the product in the import sheet under Water levels. Is there somewhere to enter the Product density in ESdat?

ESdat will calculate a corrected water elevation for you given a depth to water level and depth to product (LNAPL), and a reference point (Top of Casing or surface elevation) Top of Casing is Well property, and hence is entered into the wells table. Depth to water and product are entered into the water levels table. ('Groundwater_and_NAPL_levels' in SQL Server versions). The relative density is entered into the table called ‘Site_Properties’ if you want a single value for the whole site. If you want well-specific values then the data is entered into the chemistry table with a ChemCode of 'LNAPL_Rel_Density’. The Location and WellCode must obviously match that at which the NAPL is measured. If no value is entered a default value of 0.76 will be used.
