- Board
- Maryland Department of the Environment / MD State Board of On-Site Wastewater Professionals (OSDS Registered Individuals); Charles County Health Department Environmental Health (county installer/scavenger street roster not published online)
- Status
- Named with a Charles County street on the MDE On-Site Wastewater Professionals / OSDS Registered Individuals list (List Updated September 2, 2026; pdfinfo CreationDate/ModDate Wed Sep 2 2026 UTC). Registration number printed on that roster. Charles County Health Department Environmental Health requires an MDE wastewater-provider number on septic installation permit applications and points applicants to the MDE provider list. The perc landing link “Septic contractors For Digging Percolation Test Holes” opens https://charlescountyhealth.org/environmental-health-2/ground-percolation-septic/ — a stub with no name table. Percolation Testing in Charles County (pdfinfo CreationDate Wed Jan 14 2026 UTC; footer 1/2026) does not print a contractor list. Private Consultants memorandum (March 23, 2018) lists perc-test consultants, not septic installers or scavengers. No fetchable county installer or scavenger street roster this pass — county numbers are not invented. Seeded rows claim septic_install from the printed MDE registration; county scavenger (pumping) numbers are not invented.
