Install a certified water filter at an invited Patterson home

Following an intake log flagging a Patterson household without filtration, this step gets a certified under-sink filter in place so drinking water is treated at the point of use. Standard: NSF/ANSI 53 certified filtration for nitrate reduction + SDG 6 Clean Water and Sanitation Proof: Before/after photos of the install plus the filter's certification label Method (NSF/ANSI 53 certified filtration for nitrate reduction + SDG 6 Clean Water and Sanitation): 1. Confirm the household invited this visit and a certified filter unit is on hand. 2. Shut off the cold-water supply under the sink before starting. 3. Mount the certified filter housing under the sink per the manufacturer's instructions. 4. Connect the filter to the cold line and faucet, then restore water and check for leaks. 5. Run water through the new filter for two minutes to clear the cartridge. 6. Photograph the finished install and the filter's certification label, with GPS and date. Done when: Before/after photos of the install plus the filter's certification label

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.
