Water Quality Sampling Report for 2007

The water testing protocol for the 2007 season employs the same updated protocol which was adopted in 2006. The main change in 2006 was the addition of two extra test samples per testing date. The purpose of these additional samples is to provide comparatives for evaluating sampling and testing procedures to ensure continuity of results. One of the new additional samples is a duplicate sample from an existing site being tested. The site chosen for the duplicate sample will change from one test date to the next. Using the example of the 5-27-07 testing date, Site 8 (Transfer Station/Devil's Elbow) was chosen as the duplicate. The second additional sample in the new protocol is a blank control sample taken from water that is known to be sterile, preferably from the process used to sterilize the water testing sample collection containers themselves.

The TC numbers indicate the most probable number of colony forming units of coliforms per 100 ml sample.

Coliform bacteria are introduced for the most part by warm blooded mammals. A moderate amount of total coliforms is considered a normal background level.

The EC numbers indicate the most probable number of colony forming units of E. Coli per 100 ml sample.

In this area E. coli is introduced almost entirely by human activity. Its presence usually indicates the presence of other serious pathogens.
