3. Well Points and Deep Wells. Ensure groundwater control performed by deep well and/or well point pumping systems is done without damage to property or structures and without interference with the rights of the public, owners of private property, pedestrians, vehicular traffic, or the work of other contractors. Any pumping methods used for dewatering and control of groundwater and seepage must have properly designed filters to ensure that

SP 15 of 286

Fishbeck 2 of 5 08-07-24 adjacent soil will not be pumped with the water, thus creating voids underground and around the face of the excavation or under existing structures. Ensure the loss of fines is limited to no more than 5 parts per million by volume in the extracted water. Ensure the filter design is reviewed and approved by the Engineer before placement.

Perform the dewatering operations in a proper and predetermined sequence with the excavation operation such that the perimeter, bottom, and face of the excavation are stable.

Dewatering well diameter, pumping rate and well spacing must provide adequate drawdown of the water level. Properly locate wells to intercept groundwater that otherwise would enter the excavation and interfere with the work. Install observation wells at key locations for observation of groundwater levels during the dewatering operation and excavation. Add additional wells as needed to lower the groundwater to the elevation shown on the plans.

A. Contractor shall provide, maintain, and use at all times during construction adequate means and devices to promptly remove and dispose of all water from every source entering the excavations or other parts of the work. Dewatering shall be accomplished by means which will ensure dry excavations, preserve final lines and grades, not disturb or displace adjacent soil, and avoid contamination of any surface water or storm water. All pumping and drainage shall be done with no damage to property, pedestrians, vehicular traffic, or the work of other contractors and in accordance with all pertinent laws, ordinances, and regulations. Existing drainage facilities shall not be overloaded or obstructed.

4. Excess Water Control/Handling Potentially Contaminated Groundwater.

A. If the groundwater is determined by the Engineer to be potentially contaminated (e.g., hydrocarbon sheen or chemical odor), the Contractor shall immediately cease dewatering operations and shall not resume dewatering until equipment appropriate to store the potentially contaminated groundwater is onsite and operational. Additionally, the Contractor shall manage the groundwater as contaminated until directed otherwise by the Engineer.
