La Plata County's point-of-sale program (the Continued Use Permit, formerly Transfer of Title) covers septic systems only — no well-water rider appears in it. What La Plata does have is its own Public Health water lab in Durango serving Southwest Colorado: $30 bacteriology tests, county-approved sample kits, and a 30-hour window from collection to drop-off.

County requirement	No well-water test appears in the county's Continued Use Permit (point-of-sale septic) program; new OWTS regulations took effect March 2, 2026. source ↗
County lab logistics	Drinking-water and private-well testing at the LPCPHD Water Quality Lab (185 Suttle Street, Durango). Fee: $30, paid at drop-off. Samples must be in a county-approved kit and submitted within 30 hours of collection; drop-off Monday–Thursday 8:00–3:30 at Community Development, 211 Rock Point Drive. No samples Fridays or before holiday closures.
What the lab covers	Bacteriology (total coliform and E. coli presence/absence). For metals, nitrate/nitrite, fluoride and other chemistry, the county links CDPHE's certified-lab finder. Lab staff do not collect samples.
Statewide filing	Every Colorado well sale needs the free DWR change-of-owner filing so the well permit follows the property. source ↗
