New York City, which drew some of its water supply from a point three and a half miles to the south, installed seven shallow test wells near Liberty Aircraft in 1945 and initially found no contamination. When the war ended, further investigations began, with dozens of new monitoring wells installed. In 1948, chromium was detected in three of the city test wells near Liberty, and a plume of contamination was traced for a mile from the plant. At Grumman, chromium had been found in public supply wells more than 100 feet deep. By 1949, all of Long Island s aircraft plants had installed treatment systems to remove chromium from their wastewater.31... [Pg.114]

Drilling. Common drill rigs available for monitor-well installation include cable tool, air rotary, mud rotary, reverse rotary, and hollow-stem auger. The cable tool rig repeatedly lifts and drops a drill bit, drill stem, drilling jars, and rope socket. The drill bit crushes hard rock or loosens unconsolidated material and mixes the loosened particles with water to form a slurry or sludge. The sludge is removed at intervals by a sand pump or a bailer. [Pg.166]

The specific results of well over 1 year of continued monitoring will be discussed in a second paper. It is pointed out here that the AEBIL monitoring system installed in the power plant for the above monitoring purposes has efficiently and continuedly performed during this time interval, with no instrumentation reliability problems. [Pg.71]

Detailed sampling can include, but is not limited to, the installation of monitoring well networks. After the wells have been installed, aquifer tests are typically performed. Once the aquifer tests are performed and the aquifer characteristics are determined, time series sampling for a given contaminant, or a surrogate, is undertaken. The combined results of these efforts provide the basis for development of a treatment strategy. Modeling can be used as part of this effort to help determine the best technical and most cost-effective techniques to be used at a site. [Pg.118]

Suction lysimeters are required for some field-scale groundwater monitoring studies to monitor the transport of compounds of interest through the unsaturated zone. Unlike monitoring wells or water supply wells that sample water from the saturated zone, suction lysimeters sample water from the unsaturated zone. This section provides a summary of the installation and sampling procedures for pressure-vacuum suction lysimeters. A detailed discussion of unsaturated zone sampling devices is available elsewhere. [Pg.812]

Physical and chemical monitoring is carried out through a U-tube downhole installation (Freifeld et al. 2005) that allows the collection of high quality liquid and gas samples from targeted depths. The multi-level U-tube assembly is completed in the Waarre C unit approximately 300 m distant and updip from the injector well (CRC-1). The Naylor-1 monitoring well is perforated from 2028.3 - 2032.2 m RT and 2039 - 2055 m RT. The U-tube assembly is constructed to sample from U1 at 2027 m RT (gas cap), U2 2040 m RT and U3 2045 m RT both initially below the gas-water contact. [Pg.151]

Monitoring wells were installed to a depth of 3-4 m into soft tailings at sites 1 and 2. The wells are constructed of 1.5 inch-OD PVC pipe with the lower 1.2 m perforated for collection of ground water. Water was sampled using a LDPE tubing- foot valve assembly. Ground water and surface waters were sampled monthly from August to November 2008. Temperature, pH, and conductivity were measured in the field and... [Pg.332]

Remediation commenced with the interception of the recoverable gasoline. One 4-in.-diameter vapor extraction well and three 2-in. vapor monitor wells were installed. Each well was constructed with 4 ft of well screen placed and filter packed across the unsaturated portion of the shale. The annulus of the wells was sealed to the surface with bentonite and cement grout according to local standards. The monitor wells were located in a triangular pattern around the vapor extraction well at distances of 5.3, 10.6, and 25.4 ft. [Pg.315]
