Updates from Wisconsin DNR
Nonpressurized Conduit fact sheet now available!
There is new help for evaluating the compliance of nonpressurized conduits!
A new Nonpressurized Conduit fact sheet is now available on the DNR web site. The fact sheet and flow chart can help you and your customers answer some common NR 812 code compliance questions about how to evaluate the compliance of nonpressurized conduits.
DNR has created several fact sheets designed to make NR 812 compliance easier for you and your customers. Use them online, print them out to keep with your code book as a reference, and share them with your customers. You can find the DNR Driller and Pump Installer fact sheets at: http://dnr.wi.gov/topic/Wells/factsheets.html.
A new Water Sample Requirements fact sheet is now available from DNR. The fact sheet and flow chart can help you and your customers answer some common NR 812 code compliance questions about water sampling requirements for well construction and pump installing activities.
Well Construction Report Form Updates
DNR recently revised Forms 3300-077 and 3300-077A, the multi-ply paper forms used for Well Construction Report and related First Water Quality Test. The revised version of this form contains several important changes, including:
- Latitude and Longitude must be reported in Decimal Degrees format: DD.DDDD
- List of contamination sources is updated to reflect current NR 812 code
- Space added to indicate the number of heat exchange drill holes
- Checkboxes added to make it easier to complete form
- Required license/registration number for both well driller and rig operator
Many sections on the Well Construction Report were not changed, so we hope the revised form will be just as easy to use. In the short term, you can continue to use any old paper forms you have. When you request a new batch of paper forms, DNR will send you a detailed list of form changes. Thank you.
Make sure you are using the current version of NR 812 which was effective October 1 of 2014. Every licensed well driller received a printed copy by mail. You can also use the online version of NR 812, Wis. Adm. Code.
Measuring separation distances
Choose a well location that’s as far as possible from contamination sources and meets all NR 812 separation distances. Measure separation distances from the edge of the well to the closest edge of the contamination source – for example, the toe of a mound system or closest side of an animal barn. [see NR 812.08(4), Wis. Adm. Code]
When cement grouting with a conductor pipe or “tremie” pipe, lower the pipe to the bottom of the annular space and pump from the bottom up. The end of the pipe should be submerged in grout at all times. [see NR 812.20(3)(b), Wis. Adm. Code] If you encounter unexpected problems that prevent one continuous grouting operation, you must report non-continuous grouting and the reason on your well construction report. [see NR812.20(2)(c)] Bentonite chips are not an approved grouting material, so contact your local Private Water Supply Specialist to request a variance if you need to use bentonite chips to seal off voids before continuing cement grouting.
Well construction reports
Include both the Latitude-Longitude and Public Land Survey System (PLSS) information on each well construction report. Try DNR Maps Location Finder to find both. First, open the Location Finder and zoom into your project area. To find latitude-longitude, choose “Get Lat/Long” button, click on your project site on the map, and the latitude and longitude will be displayed in Decimal Degrees (DD) format. To find the PLSS, choose the “Get Info” button, click on your project site, and the section-town-range information will be displayed on the left. Submit your well construction report to DNR within 30 days of the day the well was completed or constructed. [see NR 812.22(7), Wis. Adm. Code]
