Water Quality Monitoring Program, Airport Construction Site, Moen Island, Truk, Trust Territory of the Pacific Islands, Part C: Post-Construction

No abstract was published. A summary of the Introduction follows.

Expansion of the Truk International Airport runway on Moen Island began in the summer of 1978 and finished in December 1981. The Part C Post-construction water quality (WQ) monitoring program was conducted in July 1982. In this program, the marine WQ stations used in the Part A and B programs were monitored over a 5-day period. Water quality analyses were used to assess post-construction WQ in relation to: 1) the Part A Pre-construction turbidity standard; 2) the TTPI WQ standards; 3) and Part B Construction WQ data and observations. This study of water quality in the Part C Post-construction period was requested by the U.S. Navy in accordance with Contract No. N62742-78-C-0029, Part C. It was a portion of the third part of a three-part environmental monitoring program which consisted of:

  • Part A. Pre-construction Monitoring Program
  • Part B. Construction Monitoring Program
  • Part C. Post-construction Monitoring Program

Each of these parts is further divided into two portions: (1) a water – and, for Parts A and B, noise and air – quality monitoring program and (2) a biological monitoring program. The biological monitoring program for Part C was undertaken by the Marine Laboratory of the University of Guam and is described in a separate report (Amesbury et al., 1982). The Part A water quality monitoring program took place over a 3-month period in 1978 (WERI Technical Report No. 7 by Clayshulte et al., 1979). Eight water quality monitoring stations were established adjacent to the airport construction and dredge sites and ninth station was established as a control. The objectives of the Part A study were to determine baseline water quality and to develop turbidity limits to be used by the contracting agency to control changes caused by construction activity. The objectives of the Part B study (WERI Technical Report No. 35 by Clayshulte and Zolan, 1982) were to monitor WQ in order to assess compliance with the Part A Pre-construction turbidity standard and the TTPZ water quality standards.

Control of Truk International Airport was officially transferred to Truk State from the U.S. Navy (OICC) in December 1981, coinciding with the completion of the Part B monitoring program. However, at the time of official transfer, some construction operations were still in progress in the Part C monitoring program.
