When it comes to groundwater sampling we've made it our business to know what's what and with regulatory directives such as the European Water Framework Directive (EWFD) impacting protocols and equipment developments we work continuously to ensure that whether you're remediating, sampling or purging; your head of water is 5 or 500 metres; you have a high, low or no flow rate and the volume of suspended sediments is unknown – we have the right groundwater pump, groundwater sampler, hall marked filter or groundwater sampling tubing and monitoring well pipe for you.
