Install a certified nitrate-rated water filter in an invited home near Toppenish

Private wells across the Lower Yakima Valley have documented nitrate contamination — the county and EPA have run a groundwater management program here for more than a decade. Families on affected wells still haul bottled water or drink untreated tap. A certified point-of-use filter at one invited kitchen tap is a same-day fix that a household can maintain themselves. Standard: EPA Safe Drinking Water Act nitrate standard (10 mg/L) + Lower Yakima Valley Groundwater Management Area; SDG 6 (Clean Water and Sanitation). Proof: photos of the installed certified filter, date label, and host well-test context Method (EPA Safe Drinking Water Act nitrate standard (10 mg/L) + Lower Yakima Valley Groundwater Management Area; SDG 6 (Clean Water and Sanitation).): 1. Confirm the host's invitation and review their most recent well test result together. 2. Install a point-of-use filter certified for nitrate reduction at the kitchen tap following the manufacturer's instructions. 3. Flush the new filter for the full time the instructions require and run a first-draw check. 4. Label the unit with the install date and the next cartridge-change date. 5. Photograph the installed filter, the labeled date card, and the well test result together, GPS-tagged and dated. Done when: photos of the installed certified filter, date label, and host well-test context

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.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 30–60 minutes. Method of record: EPA drinking-water sampling (3Ts / LCR first-draw where lead is in scope)

Bring

• GPS-capable phone
• test kit for each named analyte (nitrate/coliform/arsenic/lead as specified)
• clean sample bottle + label
• nitrile gloves
• camera

Steps

1. 1. Navigate to the sampling point; confirm GPS is inside the posting radius; record the waypoint.
2. 2. Photograph the tap or wellhead with a legible timestamp.
3. 3. If first-draw is required, sample after >=6h stagnation; if flushed, run the tap 2-3 minutes first, then sample.
4. 4. Fill the bottle without touching the inside; cap immediately.
5. 5. Run each test per kit instructions; wait the exact develop/incubation time; read and record every value with units.
6. 6. Record coliform as present/absent after the stated incubation window.
7. 7. Enter all readings, units, GPS, time, and photos into the proof record; sign it.

If it does not match the plan

• Nitrate > 10 mg/L -> tag 'exceeds EPA MCL'; advise no infant consumption pending certified-lab confirmation.
• Total coliform present -> advise disinfection + retest; recommend lab confirmation.
• Arsenic > 10 ppb or Lead > 15 ppb -> tag exceedance; recommend certified-lab confirmation before any consumption guidance.

What counts as done

• GPS waypoint recorded inside the posting radius
• Timestamped photo of the exact sampling point
• Each required analyte recorded with a numeric value + units (or present/absent)
• Sampling type (first-draw vs flushed) explicitly noted

Proof is measured against these, not judged by taste.
