• Determine Tier 2 soil cleanup object- ives by both the USEPA SSL and the ASTM RBCA methods - simultaneously.

    • Determine projected ground water concentra- tions any distance from the source.

    • Determine the downgradient distance needed to meet ground water cleanup objectives.

    • Add and remove constituents from the database, and change default values as new information becomes available.

    • Perform mixture rule calculations effortlessly.

    • TACO Plus! keeps track of Csat and solubility data so physically imposs- ible situations do not arise.

    TACO Plus! ...

    TACO Plus! is a Microsoft® Jet database-based software program that calculates appropriate cleanup objectives under the Illinois EPA's TACO rule (35 IAC 743).

    You may be asking yourself ...

    Why do we calculate concentrations of contaminants in ground water at the
      source? - didn't I measure them?
    What's the difference between h and qT?
    What's the difference between ks, Kd, and Koc? and when do I use each?
    What's an error function and why do I need it? (I don't think I made any errors!)
    What's the effective diffusivity of benzene?
    Is benzoic acid ionizable?

    If so, perhaps TACO Plus! can help.

    How would you like to ...

         ... identify Illinois Tier 1 soil and ground water cleanup objectives in less than a
         minute?

         ... perform a site-specific, detailed Tier 2 TACO analysis in less than 15
         minutes?

         ... determine the effect of moving a downgradient compliance point on cleanup
         objectives in less than 5 seconds?

    If so, perhaps TACO Plus! can help.

    TACO Plus! allows you to enter site-specific information easily and intuitively.  For example, the following figure shows the input form for the physical dimensions of the site and for entering constituents found there -

    The results of calculations are also presented clearly.  The following figure shows the output form for the SSL calculations.

     

    Of course, nothing takes the place of knowledge, understanding and experience - but TACO Plus! can go a long way toward helping junior Environment Professionals perform a defensible analysis, and free senior staff from the time-consuming tasks of performing calculations, and let them focus on what's important - analyzing situations and developing cost-effective approaches.
