Redwood City <br /> Water Quality Monitoring Program Plan <br /> <br /> <br />© 2014 DKF Solutions Group, LLC Page 23 of 41 <br /> No sample or measurement is worth the risk of injury. <br /> All staff shall use proper personnel protective gear as appropriate for the incident (e.g., life <br />preservers, gloves, goggles, etc.) <br /> Field sampling crews should consist of at least two members unless otherwise <br />approved by a supervisor. <br /> Be conscious of the whereabouts of rattlesnakes, mountain lions, and other <br />dangerous animals. <br /> Open body wounds are entry sites for infection; take the necessary precautions for <br />self-protection. <br /> If there is storm activity in the work area, wait for safer conditions to develop or <br />postpone the sampling. <br /> Do not sample at night without approval from your supervisor. <br /> Do not trespass on private property, or posted restricted public lands without prior <br />permission and written approval from property owner or administrator. <br /> If strange or suspicious looking people are in the work area, either wait for them to <br />leave or postpone the work to a later time. Do not force confrontations with strangers <br />and back away from any confrontations with the public. Be courteous and understanding <br />of public concerns of the situation. <br /> Take the necessary precautions against exposure to harmful weather conditions such <br />as heat, wind, snow, cold, rain, etc. <br /> Carefully evaluate a given on-site situation to determine if the task can be performed <br />safely. <br /> Wear protective footwear when entering streams. <br /> Do not enter the stream if the water is flowing too fast. <br /> <br />F. Stream Velocity Measurements <br />If sampling is performed after the SSO has stopped, the velocity of the impacted surface <br />water must be determined in order to estimate SSO travel time and select an accurate Source <br />sample location. One way to measure the SSO travel time is to use a velocity probe (such as <br />a Global Water FP111-S Flow Probe) to determine the rate of flow in the water body. In <br />cases where a water velocity probe is used, the manufacturer’s instructions will be followed. <br /> <br />G. Grab-n-Go Sampling Kit <br />The City maintains a Grab-n-Go sampling kit located at Public Works Wastewater day room, <br />and Emergency Response vehicle/trailer. The kit is to be inspected quarterly, and <br />replenishing after each use. Sampling equipment and field monitoring devices shall be <br />decontaminated after each use. <br /> <br />SSO Sample Collection Kit Inventory: <br /> Cooler <br /> Surface Water Sampling SOP (Attachment B) <br /> Ice Pack (stored in freezer) <br />6.2.A. - Page 189
