Document the Lavaca Bay shoreline context near a former industrial discharge Superfund site, site 5, Point Comfort City Park, Point Comfort, TX 77978 (2026-07-29)

This stretch of Lavaca Bay shoreline sits near a former industrial discharge Superfund site with long documented mercury contamination in bay sediment and fish tissue, and a current public photo record of posted advisory signage helps residents and regulators track the long term cleanup and monitoring effort. Standard: US EPA soil screening levels for residential and ecological exposure, applied here as a document only stand off survey of the Lavaca Bay mercury legacy sediment context from the public grounds of Point Comfort City Park, Point Comfort, Calhoun County, Texas, a former industrial discharge Superfund site under long term federal cleanup and monitoring. SDG 3.9 and 12.4 hazardous material reduction. Proof: document only stand off photo log plus advisory signage note plus GPS plus ranked follow on note Method (US EPA soil screening levels for residential and ecological exposure, applied here as a document only stand off survey of the Lavaca Bay mercury legacy sediment context from the public grounds of Point Comfort City Park, Point Comfort, Calhoun County, Texas, a former industrial discharge Superfund site under long term federal cleanup and monitoring.

From Point Comfort City Park, a public park and vantage point, photograph the bay shoreline and any visible advisory or monitoring signage without touching the water, sediment, or shoreline. 2. 2. Note any posted fish or shellfish consumption advisory signage visible from the public park. 3. 3. Photograph the nearest park sign or mile marker for reference. 4. 4. Record a ranked follow on note naming the segment for a licensed environmental assessor's review, never collect a physical sample.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 45–90 minutes. Method of record: EPA soil screening (composite surface sample, XRF/field kit)

Bring

• trowel or auger
• clean bucket + mixing tool
• XRF analyzer or metals test kit
• PID for volatiles (if petroleum in scope)
• sample bags + labels
• N95 dust mask
• gloves + eye protection
• GPS phone
• camera

Steps

1. 1. Navigate to the parcel; record GPS; sketch a >=5-point sampling grid.
2. 2. Photograph each sampling point and any visible staining/fill/slag.
3. 3. Collect 0-15 cm cores from >=5 points; combine and mix in the clean bucket; subsample.
4. 4. Run XRF/test kit on the composite; record each metal in ppm.
5. 5. If petroleum is in scope, log PID readings and any odor/staining.
6. 6. Bag/label any lab subsample; complete chain-of-custody.
7. 7. Enter all analytes with units, depth, GPS, photos, and site sketch into the proof record; sign.

If it does not match the plan

• Lead > 400 ppm (residential) -> tag exceedance; advise raised beds / produce-washing / cover; recommend lab confirm.
• Arsenic > site screening level or PID indicating volatiles -> tag; recommend certified-lab confirmation before reuse.
• Suspected asbestos-containing material -> do not disturb; flag and stop.

What counts as done

• >=5-point composite collected at 0-15 cm
• Each screened metal recorded in ppm
• Visible staining/fill/slag noted (or absence)
• GPS waypoint + point photos + grid sketch

Proof is measured against these, not judged by taste.
