ESI has frequently been retained to assist with the development of landfill monitoring networks and protocols and the establishment of data management systems. With the introduction of new regulations, the requirements to monitor landfill gas, leachate, groundwater and surface water quality continue to increase. The range of chemicals that are potential environmental threats is large and complex, and it is important that monitoring points are correctly positioned and precisely installed to ensure that the data collected are necessary, sufficient and reliable.

Once monitoring points are installed, samples must be collected and handled properly, so that the data provide a representative picture of the conditions that are being monitored. Adherence to appropriate guidelines is necessary so that the results are acceptable to regulatory authorities.

ESI uses its skills and expertise to build a clear understanding of the potential contaminant transport routes around a site in order to design monitoring and sampling systems that meet the needs of the operator and of the regulator. We are also able to advise on appropriate assessment criteria (control and trigger levels).

ESI can provide bespoke support to landfill site operators and third parties on the improvement of monitoring networks and installations.

Service: - Landfill Monitoring Support Service

	Design of environmental monitoring networks and suitable borehole design specifications;
	Review and assessment of existing monitoring facilities, including their effectiveness, quality, sufficiency and positioning; design of additional monitoring points as required;
	Supervision of installation of new monitoring facilities;
	Assessment of existing monitoring plans, procedures and activities;
	Identification of the reasons for unreliable or unrepresentative data (such as borehole condition, incorrect positioning of monitoring points, insufficient attention to purging and quality control of sampling);
	Production of monitoring protocols with due consideration of regulatory requirements, best practice and cost-efficiency;
	Advice on appropriate monitoring suites for requisite surveillance at the site; and
	On-going data management, analysis, interpretation and reporting (see data management systems);

	Landfill site improvement condition for PPC permit
	Landfill groundwater monitoring network design and construction quality assurance (CQA)

ESI can help you to ensure that your landfill monitoring is appropriate to the site, gives the appropriate data that provides indicators of any potential contamination and thus limits your environmental liabilities. Our considerable experience in soil and groundwater science enables us to do this in such a way as to minimise your recurrent costs for monitoring (which can be very high). Our proven track record and strong working relationships with regulatory authorities also enables pragmatic discussions and satisfactory solutions to be found where negotiation is needed.

Please contact ESI (01743 276100 / email) for more information on landfill monitoring support service.
