After pressure grouting,the top three feet of casing was drilled <br /> out and more Portland cement was added to the top of the remaining casing, and allowed to flow <br /> over the edge of the remaining casing to about six inches above the top of the casing.

The <br /> well boxes were then removed and replaced with like-material to match the surrounding area. <br /> EX-1 was not drilled out because it had a stainless steel casing. This well was pressure grouted <br /> on April 18,2012.
