Meet State and Federal Compliance Requirements

CWM’s groundwater team performs groundwater and surface water sampling from landfills and industrial sites five days a week, 52 weeks a year. We’re efficient, cost-effective, and use the latest equipment and approved methods.

Our samplers use submersible pumps, low flow micro purge bladder pumps, and traditional bailers for sampling depending on the client’s requirement.

Field parameters are measured using a state-of-the-art electronic flow cells which can monitor parameters in real time.



Landfills receiving more than 20 tons of solid waste per day are required to monitor underlying groundwater during active life and post-closure for 62 constituents listed in 40 CFR part 258.
