Install a point-of-use water filter for the tap this source feeds — Highland Public Library, Lafayette LA (2026-07-24)

The potability test at Highland Public Library, Lafayette LA flagged a contaminant. Install an NSF/ANSI-certified point-of-use filter on the tap or spigot this source feeds, sized to that contaminant, and confirm the fix with a retest. Standard: EPA Point-of-Use / Point-of-Entry (POU/POE) treatment device selection + NSF/ANSI 42/53/58 certified contaminant reduction; SDG 6.1 safely managed drinking water. Proof: before/after test readings + NSF/ANSI label photo + install date/next-service label + GPS waypoint — Real, Proven, One-of-one Method (NSF/ANSI-certified point-of-use water treatment install, sized to the contaminant the potability test found (lead/bacteria/nitrate/turbidity), per EPA POU/POE guidance and manufacturer instructions — assess->install->verify, ~60-180 min): 1. ASSESS: read the potability test result and pick an NSF/ANSI-certified device rated to reduce the specific contaminant flagged (lead/bacteria/nitrate/turbidity). 2. Shut off the local water supply and install the device at the point of use (or point of entry for a whole-building concern), following the manufacturer's instructions. 3. Flush and prime the new device per the manufacturer's start-up procedure before it is used for drinking water. 4. Post-install retest: run the same test the audit used and confirm the flagged contaminant is now below the safety threshold. 5. VERIFY: label the unit with the install date + next filter-change date, and leave the household/site a plain-language card explaining what it does and when to service it. Equipment: NSF/ANSI 42/53/58-certified filter or treatment unit matched to the flagged contaminant, basic plumbing hand tools (wrench, tubing cutter, Teflon tape) or a certified installer for a whole-building POE unit, test strips or a second lab sample kit for the post-install retest, GPS device / phone for the waypoint Done when: Device is NSF/ANSI-certified for the specific contaminant the test flagged; Post-install retest confirms the contaminant is below the safety threshold; Install date + next-service date labeled on the unit; No leaks at any fitting after a full flush cycle

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.
Proof: before/after test readings + NSF/ANSI label photo + install date/next-service label + GPS waypoint — Real, Proven, One-of-one

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 60–180 minutes. Method of record: NSF/ANSI-certified point-of-use water treatment install, sized to the contaminant the potability test found (lead/bacteria/nitrate/turbidity), per EPA POU/POE guidance and manufacturer instructions — assess->install->verify

Bring

NSF/ANSI 42/53/58-certified filter or treatment unit matched to the flagged contaminant
basic plumbing hand tools (wrench, tubing cutter, Teflon tape) or a certified installer for a whole-building POE unit
test strips or a second lab sample kit for the post-install retest
GPS device / phone for the waypoint

Steps

1. ASSESS: read the potability test result and pick an NSF/ANSI-certified device rated to reduce the specific contaminant flagged (lead/bacteria/nitrate/turbidity).
2. Shut off the local water supply and install the device at the point of use (or point of entry for a whole-building concern), following the manufacturer's instructions.
3. Flush and prime the new device per the manufacturer's start-up procedure before it is used for drinking water.
4. Post-install retest: run the same test the audit used and confirm the flagged contaminant is now below the safety threshold.
5. VERIFY: label the unit with the install date + next filter-change date, and leave the household/site a plain-language card explaining what it does and when to service it.

If it does not match the plan

Contaminant not reducible by a POU/POE device (e.g. a systemic municipal/utility issue) -> STOP, route to the water utility or local health department instead of installing.
Lead result at or above the EPA action level from a whole-building source (not a single tap) -> a licensed plumber assesses point-of-entry treatment or service-line replacement; do not scope as DIY.
Any active leak or supply-line damage found during install -> stop and route to a licensed plumber.

What counts as done

Device is NSF/ANSI-certified for the specific contaminant the test flagged
Post-install retest confirms the contaminant is below the safety threshold
Install date + next-service date labeled on the unit
No leaks at any fitting after a full flush cycle

Proof is measured against these, not judged by taste.
