WELL DRILLING & DESIGN AND
WELL REHABILITATION

Richard C. Slade and Associates LLC, Consulting Groundwater Geologists, have been retained by numerous water agencies, cities, water districts and private water companies to develop their local groundwater resources. The types of services provided to these agencies have depended on the needs of the client but have tended to include the tasks listed below.

NEW WELLS

Prepare Technical Specifications

identify the location and depth for new onsite wells

assess site logistics for well construction

determine drilling methodology

evaluate conditions for discharge of fluids under NPDES permit regulations

prepare detailed technical specifications and line item estimates of the probable cost for drilling and constructing new wells

assist in bidding process.

Field Monitoring Services

geologically log drill cuttings from pilot hole

evaluate the electric log of the pilot hole

select depth zones and monitor aquifer zone isolation testing for water quality in selected aquifers

provide final recommendations for placement of all well casing, perforations, gravel pack and cement seals

monitor the installation of the recommended casing, gravel pack, and cement seal

monitor well development by mechanical and pumping methods

conduct pumping (aquifer) tests

monitor water levels and utilize water level pressure transducers

identify sampling/laboratory protocol for groundwater sampling

monitor spinner log survey and depth discrete-sampling

determine water quality parameters to test for in the laboratory

recommend pumping rate and depth setting for permanent pump

provide report to document well construction and testing activities

EXISTING WELLS

Well Evaluation for Rehabilitation/Destruction
