Parkinson's Arco c- ' �_ t Page 2 of 2 <br /> �,. - - fir✓ � �, <br /> Subject: Parkinson's Arco <br /> i <br /> Dan: <br /> In response to your voice message yesterday afternoon, I am attaching an example well construction <br /> diagram for your review. This is what I would like you to provide in your work plan addendum. You do not <br /> have to provide the drilling method as long as the driller meets the well standards provided in the workplan <br /> addendum that you plan to submit to San Joaquin County Environmental Health Department for approval. <br /> One reason for requesting the drilling method is that when augers are used to construct the borehole, the <br /> wobbling motion of the augers creates a hole with more than a 12-inch diameter, and as long as the <br /> borehole diameter is twelve and five-eights inches, it will meet the well standards for the most well <br /> installations. You plan to use Schedule 80 PVC casing; it may have an inside diameter of two inches but <br /> an outside diameter of two and one-half inches. Make sure you indicate the outside diameters in your well <br /> construction diagram. I hope this information is helpful. <br /> <<Well Construction Diagram_.pdf>> <br /> Vicki McCartney,Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> 304 E.Weber Avenue <br /> Stockton,CA 95202-2708 <br /> Phone: (209)468-3456 <br /> Fax: (209)468-3433 <br /> E-mail: vmccartney@sjcehd.com <br /> *****************Internet Email Confidentiality <br /> Footer****************** <br /> Privileged/Confidential Information may be contained in this message. <br /> If you are not the addressee indicated in this message (or responsible <br /> for delivery of the message to such person),you may not copy or <br /> deliver <br /> this message to anyone.
