Abstract: An automated self service method of and system for cashing checks, typically without human intervention. The system includes a check cashing database that contains customer records for registered customers. A plurality of administration modules are provided with which individuals may register themselves and their checks and communicate with customer service representatives. A check cashing server communicates with the check cashing transaction modules. The check cashing server receives check cashing requests from the check cashing transaction modules. The check cashing server processes check requests by comparing information in the request with criteria derived from the check cashing database. If the check request satisfies the criteria, the check cashing server, without human action or intervention, instructs the check cashing transaction module to dispense cash to the customer.

Abstract: An improved method and apparatus for monitoring the concentration of contaminants, including volatile organic compounds, in groundwater is provided comprising a semipermeable membrane defining an inner chamber therein. The membrane is permeable to contaminants but impermeable to a reference fluid, which is preferably distilled water. The method of sampling comprises placing the semipermeable membrane, which contains the reference fluid, in contact with contaminated groundwater, thereby allowing contaminants to diffuse through the semipermeable membrane and into the inner chamber. Sufficient time is allowed for the contaminant concentrations in the groundwater and in the reference fluid to reach equilibrium. The semipermeable membrane is then removed from contact with the groundwater, and a sample withdrawn from the inner chamber for analysis, preferably through a port communicating with the inner chamber.
