Well Development The development procedure for groundwater monitoring wells consists of allowing a bailer to fall freely through the well until striking the surface of the water The contact of the bailer produces an outward surge of water that is forced from the borehole through the well screen and into the formation This tends to break up bndging of fines that may have developed within the well screen The water is then bailed out of the well using a bailer In addition to development by bailing, purging and surging with a surge block is also used The surging action created in the borehole causes the particular matter outside the well intake to flow into the well Continued bailing removes the particulate matter from the well Groundwater produced during development is contained in 55-gallon D O T steel drums and transported to a State-approved water reclamation facility Groundwater Sampling The groundwater sampling procedure consists of first measuring the water level and then visually checking for the presence of sheens using a clear disposable polyethylene bailer Each well is then purged of a minimum of four casing volumes of water (or until dewatered) by pumping using a submersible or centrifugal pump with new disposable polyethylene or PVC hose Groundwater samples are collected using disposable polyethylene PVC or stainless steel bailers after the wells recover to atleast 80% of the pre-purge static water level The samples are placed into appropriate EPA- approved sample containers, labeled, logged onto Chain-of-Custody forms, and transported in a cooler with ice to a Stated-certified analytical laboratory Purge water is contained in 55-Gallon D O T steel drums and transported to a State-approved water reclamation facility Chain-of-Custody documentation is presented with the Certified analytical laboratory reports i
