High quality groundwater sampling
Representative Samples A project manager’s goal for groundwater sampling is to collect samples that are representative of actual in-situ conditions, and to maintain sample integrity by minimizing the changes in sample quality and chemistry during collection. Sampling has evolved from earlier techniques of bailing and high rate pumping, to techniques of minimal drawdown and low flow pumping. ...

CL-Out Pilot Study Vandenberg AFB – successful aerobic cometabolism Case Study
A pilot study of the applicability of CL-Out aerobic cometabolism of PCE and other chlorinated solvents was completed at Vandenberg Air Force Base. The pilot study consisted of injection in a single well and groundwater sampling at four surrounding wells to monitor the progress of bioremediation. During the pilot study, samples were analyzed for the contaminants and breakdown products, ...

The Advantages of Passive Groundwater Sampling
Since passive groundwater sampling was introduced over 20 years ago, the reliable, cost-effective sampling collecting alternative to groundwater purging has gained wide acceptance by environmental regulators and consultants. This form of groundwater sampling allows the collection of a representative sample from a discrete position within the well screen without active groundwater transport ...

Better Remediation Through Effective Groundwater Sampling
One of the keys to successful remediation of a contaminated property is effective groundwater sampling. A new ASTM standard will aid groundwater samplers by taking a look at three types of passive samplers and their advantages, disadvantages and limitations. The new standard is D7929, Guide for Selection of Passive Techniques for Sampling Groundwater Monitoring Wells. The three types of samplers ...
