Have the efforts to use a smaller bailer in well DH -67B been successful? <br />Sometime in the past several years DH -67B had a slight offset, enough of an offset that prevented retrieving a <br />water sample. The offset did not completely close the hole and I have been able get a depth to water <br />measurement. To answer your question, I have attempted to use a total 5 variations of bailers in an attempt to <br />get the sample. The first being my standard bailer, a 1 -inch PVC, approximately 6 -ft bailer. The second a 1 <br />flexible clear tube bailer, third a short flexible hose bailer, the fourth a'/2 -in garden hose and the last a'/ inch <br />flexible tube. There were several problems that I encounter when trying to retrieve the water sample, the first <br />obviously the offset in the hole, but the second is the moisture on the sides of the drill hole. When I try the <br />smaller bailers, which are lighter, the string and bailer itself adheres to the wet sides of the drill hole thus <br />preventing the bailer to get past the offset. In an attempt to get these bailers down the hole I have increased <br />the weight attached to the bailer but that presented a different problem, the weight gets caught in the area of <br />the offset. On numerous occasions I nearly lost the bailer because of this. During my visits to this site I always <br />try to make attempt to collect the sample but with no success, that is until my last visit to the sight in December <br />of last year. <br />2. If it has been successful, how long has the smaller bailer been implemented at the site? <br />As mentioned above, I was able to get one of the 1/2 -in. garden hose bailers down the hole last December, <br />why it worked this time and not in the past I'm not sure. Either the moisture on the sides of the hole was <br />different or there was a change in the offset. Either way a sample was collected. <br />https://mail.google.com/mail/b/AKVXdwzSS3GFhuiMiFayiXVwYONa_zmA_oowV-OVgS3oywmaFmQg/u/0/?ui=2&ik=deb7fOcd20&jsver=nwJUtiz7310.e... 1/2 <br />
