This work was carried out as part of the UK Water ● Second part of Chemical Investigation Programme tests for trace substances in wastewater ● Severn Trent programme will see 11,000 samples taken in fi ve years ● Bespoke so ware aids sample management with handheld units larger scale CIP2 scope of works and technical speci‚ cations, meant that we were well placed to deliver the Severn Trent CIP2 project which will identify the occurrence, sources and removal of the substances, and delineate the scale of any improvements in e„ uent quality required in order to meet the objectives under the forthcoming stages of the Water Framework Directive. As the ‚ ndings from CIP1, and revisions to the Priority Substances Directive determined that the detection limits should be set much lower in CIP2 and the list of compounds to be monitored has also been expanded, the sampling and monitoring has become more complex. Under CIP2, our technicians will collect almost 11,000 samples from 130 Severn Trent Water sites. Meeting all the challenges set by CIP2 in terms of logistics is certainly no small feat. Working on numerous Severn Trent Water WwTW and catchment wide sites requires thorough Health and Safety (H&S) operating procedures. To enable the e' ective management of these requirements, we provided ISO 17025 accreditation, Health and Safety certi‚ cation and procedures and lone worker systems whereby the ‚ eld technicians have been issued their own access fobs to each of the WwTWs, enabling time e• cient sample collection. In addition, we developed eniCIP, a bespoke piece of so– ware speci‚ cally developed to aid sample management from sample collection through to analysis of results. The database stores, records and analyses all of the information pertaining to each and every sample including; GPS, photographs, sampling and analysis requirements, H&S, chain of custody, results and KPI reporting. eniCIP simpli‚ es the process of monitoring for Severn Trent Water, as well as the labs at i2 Analytical and the NLS. The traceability of the samples we take and the e• cient analysis and reporting that eniCIP enables has made it easier to meet CIP2's stringent requirements for all parties involved. During sample collection, the technicians use hand held tablets in the ‚ eld which operate using eniCIP. Each sample has a barcode which is scanned and together with photographs of the sample and the site, is uploaded to the eniCIP database along with the GPS Industry Research and Environment Agency led Chemical Investigations Programme (CIP1), in order to uphold both the Water Framework Directive and the new European Priority Substances Directive.
