Install a certified under-sink filter matched to the test at an invited East Porterville home

East Porterville homes whose tests flag nitrate, taste, or sediment need a filter matched to the actual finding — carbon for one problem, reverse osmosis for another. Installing the right certified unit at the kitchen tap turns the household's test result into daily safe water. The town that hauled emergency water tanks for years deserves taps it can trust. Standard: NSF/ANSI 53/58 certified point-of-use filtration matched to contaminant; SDG 6 Clean Water. Proof: Photos of installed unit, running tap, dated schedule with GPS/date Method (NSF/ANSI 53/58 certified point-of-use filtration matched to contaminant; SDG 6 Clean Water.): 1. Match the certified filter type to the home's recorded result. 2. Shut the supply, install the unit per manufacturer instructions, and restore supply. 3. Flush per spec and check all fittings dry. 4. Write the cartridge schedule on the unit with the host. 5. Photograph the installed unit and running tap and record with GPS and date. Done when: Photos of installed unit, running tap, dated schedule with GPS/date

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.
