Check the drinking-fountain water at a senior center near Tacoma WA (2026-08-04)

Kids and visitors drink from the fountains at a senior center near Tacoma WA every day, but the water has not been tested lately for lead or bacteria. Do a simple fountain-water check so the people who drink here know it is safe. Standard: EPA MCL lead action level 15 ppb, total coliform absence; SDG 6.1 Proof: photo of each tap/fountain sampled + GPS waypoint + labeled reading (lead ppb, coliform present/absent) + date Reference method for the drinking_water_safety standard (EPA drinking-water sampling (3Ts / LCR first-draw where lead is in scope), ~30-60 min): 1. Navigate to the sampling point; confirm GPS is inside the posting radius; record the waypoint. 2. Photograph the tap or wellhead with a legible timestamp. 3. If first-draw is required, sample after >=6h stagnation; if flushed, run the tap 2-3 minutes first, then sample. 4. Fill the bottle without touching the inside; cap immediately. 5. Run each test per kit instructions; wait the exact develop/incubation time; read and record every value with units. 6. Record coliform as present/absent after the stated incubation window. 7. Enter all readings, units, GPS, time, and photos into the proof record; sign it. Equipment: GPS-capable phone, test kit for each named analyte (nitrate/coliform/arsenic/lead as specified), clean sample bottle + label, nitrile gloves, camera Done when: Photo of the drinking fountain or tap sampled with timestamp; GPS waypoint of the sampling location; Lead reading (ppb) via test kit or lab; Total coliform present/absent result; Note of any cloudy water, taste, or old fixtures seen

Pay

$180 proposed

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.

Proof

photo of each tap/fountain sampled + GPS waypoint + labeled reading (lead ppb, coliform present/absent) + date

This is exactly what gets it approved. Nothing settles without it.

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

• Photo of the drinking fountain or tap sampled with timestamp
• GPS waypoint of the sampling location
• Lead reading (ppb) via test kit or lab
• Total coliform present/absent result
• Note of any cloudy water, taste, or old fixtures seen

Proof is measured against these, not judged by taste.

The standard this serves

Drinking Water Safety. Drinking water safety rests on hard numbers: the EPA and the World Health Organization publish exact limits for lead, bacteria, nitrates, and the rest, the line between water that is safe and water that only looks safe. Clear water can fail the test; slightly cloudy water can pass it. Only the test knows. Mastery means clean sampling habits, honest custody of every sample, and readings a stranger can trust. This packet is one correct sample or one careful reading, taken by the book. Every safe glass of water stands on somebody having done this properly.
