I am writing to voice opposition to the new requirement that all private class IIIC wells be grouted using a pumpable grout.  3/8" Bentonite chips have long been allowed to be poured from the surface for wells with a 20' grouting requirement.  They provide 100% solids grout seal and also provide structural support for the well casing.  Bentonite chips are designed by the manufacturer specifically for this purpose, and I see no evidence to change the existing private well regulations regarding their use.

I copied the above and fully agree.
