Surface Verification & Method Record

Substrate assessment, method applied, dwell time, pH outcome
04
Substrate: Limestone facade, 4-story HOA building exterior (Building 4 north + west elevations). Pre-existing organic growth (moss, algae, mold) identified at 35–40% surface coverage. Growth concentrated in shaded northwest corner near ground level, likely from irrigation overspray.

Method: Soft wash applied via roof-mounted 5-gallon spray system (no high-pressure rinse). SH diluted to 0.75% application strength — appropriate for limestone (avoids acid etching). Apple Wash surfactant added at 0.15% for improved coverage on vertical surface.

Dwell time: 4 minutes 30 seconds (270 seconds). Organic matter visibly neutralized within first 3 minutes. Low-pressure rinse at 800 psi initiated at dwell completion — well below limestone's 1,200 psi damage threshold.

pH outcome: Runoff pH measured at 11.2 during application (alkaline from SH). Post-rinse pH neutralized to 7.2 — within EPA-acceptable discharge range (6.0–9.0). Gatekeeper: PASS ✅

BMP Audit Narrative

Water recovery, drain protection, runoff disposition
06
💧

Water Recovery

Wastewater recovery vacuum deployed prior to application start. Approximately 31.4 gallons of process wastewater captured from low-gradient concrete apron at building base. Wastewater hauled offsite in 50-gallon containment tank for authorized disposal per AZPDES permit conditions.

🚧

Drain Protection — 2 Storm Drains Blocked

Two storm drain inlets identified within 50-foot work zone. Drain pillows placed prior to any water application (see Before photos 1–2). Both drains remained protected throughout job duration. Drain pillows removed and inspected post-job after confirming all runoff contained.

🧪

pH Exit Interview Reading

Exit pH reading taken at storm drain closest to work zone using calibrated Oakton PCSTestr 35 meter. Reading: 7.2. Discharge cleared per Arizona ADEQ AZPDES permit threshold (6.0–9.0). Photo evidence attached (After photo 3).

🚛

Runoff Disposition

All process wastewater vacuumed and transported via sealed 50-gallon tank to authorized disposal facility (Southwest Waste & Recycle, 1200 S. 7th Ave, Phoenix AZ 85007). No discharge to storm drain, impervious surface, or adjacent vegetation.
