  • Continuing work on classifying 2025 pedons
  • Gen also working on pedon classification

63.3.2 Anthrodensic Features Analysis (Adam and Gen)

  • Identifying and documenting anthropic artifacts, anthrodensic features, and anthropic truncation in pedons
  • Need to develop better acronym or shorthand for these features
  • Randy provided feedback on mappability of these features
  • Work progressing slowly but steadily

63.3.3 Randy’s Availability

  • Randy out of office until February 9th
  • Cannot be reached directly until next bimonthly meeting

63.4 Raster Mapping and Data Work (Nora)

  • eBook broke during last update, unable to load previous meeting minutes on eBook platform
  • Reviewed action items from previous meeting via core file
  • No urgent action items identified from previous meeting

63.5 Residential Reports

63.5.1 Timeline and Resident Communications (Gen)

  • A few residents have sent follow-up emails about sending results
  • Gen managing expectations based on timeline provided during setup; no urgent pressure

63.5.2 Addresses for 2025 (Gen)

  • Gen ready to add more addresses to 2025 database when needed
  • Currently shifted focus to other tasks and will resume when processing done

63.5.3 Report Components and Template Development

63.5.3.1 Lab Data Status (Ava)

  • Still working through priority samples, including most residential sites
  • Planning to discuss additional lab tests with Nic
  • Residential sites are prioritized in sample processing

63.5.3.2 Report Structure and Templates (Adam and Team)

  • Report will include multiple components: lab data, soil formation narrative, parent material history, pXRF results for lead and arsenic
  • Lab data flowing in at varying pace
  • Draft residential reports in advance while waiting for complete lab data

63.5.3.3 Template Content (Kasia, completed)

  • Good draft template already created by Kasia
  • Copy-paste paragraphs prepared for different parent materials:
    • Glacial Till
    • Outwash
    • River system
    • Anoka Sand Plain
    • Lacustrine
    • Old Till
    • HTM (Human-Transported Material)
  • Paragraphs about lead values with conditional inclusion based on concentration ranges
  • Template designed for maximum copy-paste efficiency
  • Individual site customization will be minimal and quick
  • Unique features (such as buried surfaces) can be noted with couple of sentences

63.5.3.4 Workflow Suggestion (Adam)

  • Team members looking for work can begin drafting residential reports now
  • Process can be done incrementally:
    • Set up initial reports with site data
    • Write about parent material history and formation
    • Check pXRF sheets for concerning lead or arsenic values
    • Add information about contaminants
    • Store in draft folder
    • Add lab data as it becomes available
  • Does not need to be completed in single session
  • Can be drafted and refined over time

63.6 pXRF Analysis and Priority Flagging (Adam)

63.6.1 pXRF Processing

  • Tracking lead and arsenic values from pXRF analysis
  • Created document in lab data folder under “pXRF exports” with Pb results
  • Document highlights sites with high lead and provides context

63.6.2 Sample Progress Tracking

  • Updated 2025 sample progress sheet with PXRF results
  • Marked samples as analyzed
  • Specified presence of high lead, high arsenic, or both

63.6.3 Priority Assessment

  • Evaluating concern level based on location context
  • Industrial sites with high values noted but lower priority. Residential sites with high topsoil lead or arsenic flagged as concerning
  • Added priority tags for samples with potentially high lead or arsenic
  • Team members working on residential reports can reference these tags to prioritize which reports to prepare first

63.7 Data Requests and Communications

63.7.1 Current Data Requests

  • Only requests received so far have been from Nora’s friends and contacts
  • Requests are curiosity-based rather than urgent. Not being used to inform land management or gardening decisions for current season

63.8 Action Items

  • Adam: Edit concept key based on Randy and Patty feedback
  • Adam: Continue classifying 2025 pedons
  • Adam: Develop better shorthand/acronym for anthrodensic features
  • Gen: Continue pedon classification work
  • Gen: Add addresses to 2025 database when needed (awaiting notification)
  • Nora: Export additional pedons for Patty this week
  • Nora: Continue raster mapping data work
  • Team: Consider starting draft residential reports as capacity allows
  • Team: Reference pXRF priority flags when determining which residential reports to prioritize
