Storm sewers in the Pine Neck Creek drainage area discharge to receiving waters adjacent to a popular public beach. Earlier studies had shown that the concentration of coliform in the receiving waters was elevated, especially after a rain event.

Savin conducted field work to identify and locate potential areas of contamination. The drainage area was densely populated and had a very high traffic volume. Savin worked closely with the Owner, Engineer, public services and area residents during field work.

Manhole Inspection - Savin conducted field inspections to verify the storm and sanitary sewer system maps and inspect unusual manhole configurations. Based on this task, the maps were updated and a number of suspicious sources were investigated.

Smoke Testing - Sanitary and storm sewers were smoke tested. Smoke testing revealed several direct connections that could be sources of contamination.

TV Inspection - TV inspection was conducted on 22,200 linear feet of storm sewers.

Dye Flood Testing - The television inspection, both remote and walk-through, was used to identify direct connections of service laterals to the storm drain.
