Storm Water Services conducts both special and routine testing.Water samples gathered by hand and the real-time data received from CMANN can tell us immediately if there is a pollution problem.If water quality suddenly drops, Storm Water Services employees go to the site, look for the cause and see that the problem is addressed.Water quality data from our streams, ponds and lakes is tracked over time. This helps:
|At least six times each year, the water in our three local lakes is tested for pollution such as chemicals, bacteria and sediment levels.
A total of 28 monitoring sites are sampled each time. Those sites are only accessible by boat.
See a video of staff on the Water Quality boat sampling lake water.
||Automated devices in local streams monitor the water quality 24 hours a day. The data is sent to Storm Water Services computers. |
The network of automated stream gauges is called the Continuous Monitoring and Alert Notification Network or CMANN.
How often we test water quality
|Although not part of CMANN, there is also an automated water quality sensor in our lakes. The bright orange buoy is like an unmanned laboratory. If pollution levels increase, it sends an electronic message to Storm Water Services staff.
The lake sensor can be moved to different locations in our three lakes as needed.
Storm Water Services conducts both special and routine testing.
What we do with the information
||Staff collects water samples anytime there is a potential problem. Examples could include a sewage spill that affects a stream, pond or cove. Or an overturned tanker truck that spills its contents into a storm drain--which goes directly into a creek. We also respond when residents report possible pollution in a lake, creek or pond.|
Storm Water Services also does year-round testing at pre-determined times. This includes the stream walks, bugging and fishing, and lake sampling mentioned above.
Water samples gathered by hand and the real-time data received from CMANN can tell us immediately if there is a pollution problem.
If water quality suddenly drops, Storm Water Services employees go to the site, look for the cause and see that the problem is addressed.
Water quality data from our streams, ponds and lakes is tracked over time. This helps:
- determine trends
- measure the effectiveness of pollution-reduction efforts
- develop effective strategies to improve surface water quality.
