Tidal water areas (e.g., rivers, streams, creeks, wetlands, culverts, andswales) should be sampled as follows. Collect a minimum of onesediment sample where sediments are expected to accumulate and aminimum of one surface water sample under low and high tideconditions as follows:1. Collect a minimum of one surface-water and one sediment sample upstream of the point or area of discharge;2. Collect a minimum of one surface-water and one sediment sample downstream of the point or area of discharge;3. Collect a minimum of one surface-water and one sediment sample at thepoint or area of discharge; and4. If a potential for sediment deposition exists, then samples should also becollected from the surrounding floodplain.II. WetlandsWetlands (e.g., emergent, shrub-scrub and forested) should be sampled asfollows:A. Collect a minimum of one surface-water (if present) and one sedimentsample at the point or area of discharge;B. Collect a minimum of one surface-water and one sediment sampledowngradient of the point or area of discharge; andC. Collect a minimum of one surface-water and one sediment sample at adepression or depositional area within the wetland.III. UplandsUpland areas containing ESNRs should be sampled as follows:A. Collect a minimum of one soil sample at the point or area of discharge;Ecological Evaluation Technical Guidance Document 24Version 1.2 8/29/12
