Install certified drinking-water filters at invited well-served homes near Reedley

Outside Reedley's city system, homes on private wells and tiny systems sit over groundwater with a documented history of nitrate and legacy farm-chemical detections, and many families buy bottled water or drink the tap anyway. A certified point-of-use filter, properly installed and tagged, is the fastest real protection at the kitchen sink. Standard: State Water Board SAFER drinking-water program; SDG 6 Clean Water and Sanitation. Proof: Installed certified unit, leak-free, tagged with dates — photographed Method (State Water Board SAFER drinking-water program; SDG 6 Clean Water and Sanitation.): 1. Confirm the invited household's situation and select an NSF/ANSI-certified under-sink or countertop unit rated for the contaminants named in the posting notes. 2. Shut off the cold line, install the unit and its dedicated tap per the manufacturer instructions, and check every joint for leaks. 3. Flush the first run per the manual and tag the unit with install and next-cartridge dates. 4. Walk the household through cartridge changes and exactly what the filter does and does not treat. 5. Photograph the installed unit, the certification mark on the packaging, and the dated tag, with GPS. Done when: Installed certified unit, leak-free, tagged with dates — 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.
