Well first of all both logic and the Regional reports make it clear that there are and have been two separate water systems in Conestogo for decades. Unfortunately the choice of wording in the Township of Woolwich reports is much less clear.

The two long time wells of the Conestogo Plains System, C3 and C4, were replaced in October 2019 with the pipeline from St. Jacobs which is part of the Region's Integrated Urban System (IUS). These two wells have also supplied the village of West Montrose for a very short period of time, albeit a replacement water supply for West Montrose was decades overdue (horrible source water-bacteria). The Region's testing shows zero Coliform or E.Coli bacteria in both the raw and treated water. Again however there is a very low count of two Coliforms in the Heterotrophic Plate Count (HPC) testing. This I assume is simply the result of testing at different times. Sodium concentrations are low and generally so are Nitrates. There are ten different industrial/agricultural chemicals with Method Detection Limits above 1 part per billion (ppb) including Glyphosate (Roundup) at 26 ppb. Interestingly the two Coliforms found by the Region via HPC are magnified to nine Coliforms in Woolwich Townships report via HPC. This is another reason why I find two separate reports (or more) for the same water system to be a poor idea.

The Conestogo Golf Water Supply System consists of wells C5 and C6 located near or on the golf course itself. They have zero detections of E.Coli and total Coliforms in the treated water and one detection of total Coliforms in the raw water in the Region's report. Also the HPC indicates a detection of four Coliforms. The Woolwich Township report however indicates that six Coliforms were detected via HPC. Sodium in this Conestgo water system is a little higher than the Conestogo Plains System however it is still below the guideline of 20 mg/l. Nitrates are also a little higher although below the criteria of 10 mg/l. There are also ten industrial/agricultural chemicals with Method Detection Limits above one part per billion (ppb) with Glyphosate as it is throughout the Region at a stunning MDL of 25 ppb.
