Contacted By: BAIRD, GREGG (REGION 1)
Contact Method/Location: Office
Reasons: Coliform
Details: SUMMARY: Repeat +TC DETAILS: Regarding repeat +TC sample, see contact report previous to this. I spoke to Matt at Tigard today because they reported a chlorine residual for their two triggered well samples. Per Matt, the sample for Well #2 was collected post-chlorination because there is no raw water sample tap. I told him that we are going to invalidate that sample and asked him to retest prior to chlorination-- he indicated he would do that today by shutting off the chlorinator and make sure there was no residual prior to sampling. I spoke to him about the need for installing a dedicated raw water sample tap and he indicated that could be done-- I asked him to let me know when that was completed. Note: the sample from ASR #2 shows a residual because the surface water injected into the well has a chlorine residual so it is not surprising that the water pumped out holds a slight residual. ACTION NEEDED: Resample the raw water at Well #2. Install dedicated raw water sample tap at Well #2.
