Install certified filters at invited Richgrove homes on troubled well water

Richgrove, at the far south of Tulare County's Highway 99 farm string, has spent years on the state's lists for drinking-water problems including legacy fumigant chemicals and arsenic in its wells. While system fixes crawl, certified point-of-use filters at invited homes protect the tap kids actually drink from. Standard: State Water Board SAFER drinking-water program; SDG 6 Clean Water and Sanitation. Proof: Installed certified unit, leak-free and tagged, photographed Method (State Water Board SAFER drinking-water program; SDG 6 Clean Water and Sanitation.): 1. Confirm the invited household's situation; select an NSF/ANSI-certified unit rated for the contaminants named in the posting notes. 2. Shut the cold line; install the unit and dedicated tap; check joints for leaks. 3. Flush per manual; tag install and cartridge dates. 4. Teach cartridge changes and limits. 5. Photograph installed unit, certification mark, and tag, GPS. Done when: Installed certified unit, leak-free and tagged, photographed

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.
