Abstract: A process for in situ immobilization of metals in waste stack affected zones including a waste stack and any adjacent boundary zone. One form of the process includes: (a) forming at least one treatment passageway which extends within the waste stack affected zone; (b) injecting a treatment liquid into the treatment passageway; said treatment liquid including at least one microbe nutrient which is capable of sustaining activity of the at least one microbe; (c) providing at least one microbe in sufficient proximity to the treatment passageway to receive treatment liquid therefrom; said at least one microbe being capable of growing in the presence of said treatment liquid; said at least one microbe also being capable of producing microbial sulfides which are sulfide by-products of microbial activity in the waste stack affected zone; (d) reacting the microbial sulfides in situ with metal ions or metal-containing compounds contained in said waste stack affected zone to form metal sulfides; (e) reducing solubility of the metal ions or metal-containing compounds contained in the waste stack affected zone as a result of forming the metal sulfides; and (f) inhibiting the migration rate of metal ions or metal-containing compounds within or from the waste stack affected zone.

Abstract: A sliding bolt with stationary safety cover for mounting on a door and for locking with a padlock having a bale portion and including the following structure. A back plate for mounting on the door. An upper pair of flange members extending outwardly from the back plate and with each upper flange member including a first opening. A sliding bolt passing through and guided by the first openings in the upper pair of flange members. A lower pair of flange members extending outwardly from the back plate and with each lower flange member including a second opening for receiving the bale portion of the padlock. A handle and locking member attached to the sliding bolt and including a first upwardly extending portion forming a handle for sliding the bolt within the first openings in the upper pair of flange members and including a second downwardly extending portion located between the lower pair of flange members. The handle and locking member having a third opening corresponding to the second openings in the lower pair of flange members and with the third opening in association with either one of the second opening for receiving the bale portion of the padlock to lock the sliding bolt in either of two positions. A stationary safety cover attached across the front of and spaced from the back plate to enclose the sliding bolt, the upper and lower pairs of flanges and the downwardly extending portion of the handle and locking member.
