ENVIRONMENTAL INVESTIGATIONS, COMPLIANCE AND SITE CLOSURES

Clearwater Group has performed thousands of Phase II Subsurface Investigations. Most of the projects relate to spill responses to surface leaks, industrial processes, or tank removals. The firm operates Geoprobe® and Powerprobe® sampling rigs, as wells as other state-of-the-art techniques to assess and remediate petroleum hydrocarbons, organic solvents and metals contaminated sites. The firm has several proprietary in-situ soil and groundwater remediation methods, including the Remediation Injection Process (RIP®). Site closure is often obtained using a risk based corrective action (RBCA) computer model to evaluate possible human receptors to residual contamination, which is sometimes requested by our clients.

STORMWATER POLLUTION PREVENTION AND MONITORING

Clearwater Group designs and performs stormwater runoff studies and storm water pollution prevention monitoring. From that information, Clearwater Group build stormwater and erosion control related construction projects The firm installs high-efficiency, low-cost hydrocarbon filtration units in drop-in and curb-opening storm basins to capture stormwater runoff contamination. Typical projects include the assessment of potential sources of stormwater pollution at a manufacturing facility, developing a site map and inventory of exposed hazardous materials, evaluation of spills or leaks, identification of non-stormwater discharges or illegal connections, and collection of stormwater discharge data.

EROSION CONTROL

Clearwater Group develops erosion control plans and implements erosion mitigation measures, as by evaluating existing surface water drainage, mapping of vegetation, development, rock outcrops and surface soils. Techniques include stormwater and sediment detention basins, as well as increasing the roughness coefficient on existing drainage systems to decrease stormwater runoff velocities. Water retention areas are occasionally used for a permanent response to peak flow. Cost-effective temporary measures are used for short-term solutions.

DATA MANAGEMENT USING GPS/GIS

Clearwater Group owns and operates mapping-grade Global Positioning System (GPS) survey equipment. California state groundwater reporting laws require GPS information and laboratory data for all monitoring sites. GPS is a satellite navigation tool that captures coordinate data after a differential correction. Soil or groundwater sampling, soil remediation, and even cartographic mapping, site restoration and erosion control projects are performed using GPS with sub-meter accuracy. Clearwater Group downloads the field data into Arc-View Global Information Software (GIS).
