Results Continued: Week 4: The pH meter malfunctioned during the final week of testing, leaving it impossible to measure the pH in the field. However, because the pH measured in the lab this week, is similar to the results from previous weeks, it would be acceptable to assume that the field pH would also be showing a similar trend. The TSS results for this week were about an average fore the entire testing period. An interesting result was found, however, while testing for fecal coliforms (Table 5). This time the samples were diluted to 10 -3 which meant there was very little sample filtered. This resulted in it being possible to count, fairly accurately, every site's colonies. Site 1 and all of Site 5's agar plates did not grow any colonies, however, Site 2 and 3's did (again there were a few large clusters of colonies present). The trend of fecal coliforms is assumed to be due to the tide. While sampling it was about mid tide, but on its way back in. This would cause a lot of water from the bay to be entering site one, which pushed all of the sewage entering Marsh Creek from Dutchmen’s Creek, which has a very high concentration of sewage, and from all of the raw sewage outfalls up into Site 2 and 3 but not yet reaching Site 5. Table 5: Summary Table for Week 4 Salinity: The salinity was tested at all five sites on five separate days. The tide greatly affected these results, therefore it was arranged that the salinity was tested at all five sites, four separate times per day between low and high tide. This meant that in one day the sites would be tested from site one to site five every two hours. It was discovered after a couple days of testing that it took approximately an hour after high tide, in the bay, for the water to come through the flood gates and the creek to reach its "high tide". This also took place when the bay reached low tide. It took about an hour for the creek to drain out of the flood gates so that the creek could reach "low tide". The testing was then conducted to match the creek’s "high and low tide". The data was recorded in the field and then copied to an electronic form and put into tables. This made it very easy to calculate averages and also made the relations to the tide more noticeable. The average salinity for each site was then plotted on the following chart to demonstrate the relation with the tide (Graph 1).

ACAP expanded the sphere of stakeholder engagement in the MCRI to include the Gulf of Maine Council on the Marine Environment, as well as the RBC Bluewater program. The MCRI was also promoted to a number of new stakeholders at the 2012 Living Waters Rally in Ottawa Canada. Two noteworthy participants included the New Brunswick Law Society who researched and presented a legal opinion on the liability associated with the creosote contamination in Marsh Creek at their 2012 Annual General Meeting, and he appointment of long-time ACAP advocate Larry Hildebrandt to the position of Professor and Chair in Marine Environment Protection at the World Maritime University in Malmo, Sweden.
