  1. True Grit - True Costs, True Needs and Other Realities of Long-Term Monitoring Joe Rossabi, Ph.D Savannah River Technical Center Roger Jenkins, Ph.D Oak Ridge National Laboratory

  2. The Field is a Dirty, Messy Place Surface waters can be contaminated Monitoring wells may not be the cleanest places.

  3. You May Not be the Only Game in Town

  4. It May Not be the Moon, but You Might have to Dress Like It Is

  5. Size Matters You can’t put a 4” diameter probe in a 4” monitoring well.

  6. Don’t Forget the Arrhenius Law of Reaction Rates

  7. It isn’t always blue sky, sunshine, and 65° Thunderstorms Lightning Tornados Biggest problem: heat

  8. The Field Environment is NOT a Zoo Birds: Canada goose Mammals Deer, groundhogs Reptiles Poisonous Snakes Eastern timber rattlesnake Copperhead

  9. You are always on SOME Critter’s Food Chain Yellowjacket Wasp Arachnids: Spiders, scorpions Black Widow Brown Recluse Note violin marking

  10. Bird Poop is One of the Most Corrosive Substances Known to Man

  11. It’s a Jungle Out There!! Kangaroo Rats and Chipmunks are Cute, but will YOUR wiring become THEIR Nest Material?

  12. Overview of Environmental Technology Verification Process Statisticians Project Officers Developers • Technology developers analyze randomized samples under field conditions. Samples are collected, homogenized, labeled, and assembled for distribution. Chemists Stakeholders Experimental Plan Product is report and verification statement.

  13. Observations from Newbies • It’s hot! It’s cold! It’s raining! • Boy, the humidity must be 100%! • It’s a long way to the bathroom! • These soil samples aren’t like the one’s we looked at in the lab. • Boy, we’ve never actually tested this in the FIELD before.

  14. Baseline - Well Sampling and Analysis • Field Person - 4 wells/day ($300-500) • Find well, purge well, deal with waste. • Collect samples, coolpack samples, ship. • Laboratory ($50-$1000) • Receive, full COC analysis, QA, Report • Office Person(s) ($xxx?) • QA results, enter in database, Report

  15. Economic Analysis can be Revealing

  16. Scenarios for Long Term Monitoring • Culture, power available, unprotected Doing groundwater monitoring in the neighborhood is not as easy as it sounds

  17. Scenarios for Long Term Monitoring (continued ….) • Culture, power available, fenced, high density of wells or points

  18. Scenarios for Long Term Monitoring (continued ….) • Culture, power available, fenced, low density of wells or points

  19. Scenarios for Long Term Monitoring (continued ….) Remote, fenced or unfenced.

  20. Is it Hype, Hope, Vaporware, or the Real Deal? VaporLab Tricorder vs. Be honest with yourself and others as to how far along the technology is in its development cycle.

  21. Other Site Issues • Costs - • Samples - how many, how often • Capital and O&M costs of new technology • Philosophy - Is point sampling good enough? • Humans - • How will technicians, scientists/engineers, regulators, lawyers interface with technology

  22. Market Issues for Technologies • Environmental measurements generally not sustaining • Process technologies and crossovers have been most successful, examples … • Some niche markets, e.g., cheap access -Geoprobe,...

  23. Having Said all that... • Cheap, fast measurements • Process-like activities • clusters of wells, many measurements, remediations • Remote sites • Monitoring as continued characterization • plume and process understanding • Also: • indicator/surrogate species, micropurging, sane waste management practices
