Spa Creek water is tested every Thursday morning at eleven locations on the creek. Red indicates unsafe swimming levels.
2018 begins the third year that there has been regular water testing on Spa Creek. May 3 was the first testing of the year and beginning May 24 the testing will be weekly. The map below shows all eleven sites being tested in 2018
2018 Water Testing
The map below indicates areas where water samples are taken on a weekly basis. Red indicates areas where bacteria levels are elevated and it is unsafe for swimming. The map is updated weekly.
We are switching to bi-weekly in September. Sample collection dates are September 13 and 27.
Sampling was delaying by a week because of impedending hurricane. Sept 20, no rain within the 48 hours prior to collecting samples, testing showed high bacteria levels at South Cherry Grove and the Chesapeake Children's Museum. Water temperatures are averaging 77 degrees F, which is lower than in August. pH is at the lower end of the normal range. Total Suspended Solids are at the higher end of the normal range.
First with the good news, for the first time ever water samples taken under the foot bridge at the end of So. Cherry Grove are within safe levels for enterococci. The site of the spill last week near the Children's Museum, remains at elevated levels (200 cfu/100ml) although substantially reduced. It appears that a boat may have dumped it's sewage tank since there were elevated levels of bacteria at the end of Cheston, which normally tests within safe levels.
There was a very distinct sewage odor at the footbridge that crosses Spa Creek between the Children's Museum and Bates. Test results showed that enterococci levels were at 20,250 cfu/100ml. Anything over 104 is consider unsafe. The City of Annapolis was called Friday August 24 and again on Monday, August 27. A "Sewage Overflow" sign was eventually posted. There are also signs of a fuel oil spill closer to Bates. The county has been notified of that.
Samples were taken Thursday morning after a relatively dry week. The only areas with elevated bacteria levels are at South Cherry Grove and the Chesapeake Children's Museum. Heavy rain is predicted for the weekend which will most likely elevate bacteria levels and make Spa Creek waters unsafe to swim in.
Water samples were taken in Spa Creek on Thursday morning, Aug 2, before the afternoon and evening thunderstorms. At that time only 2 sites had elevated bacteria levels: Chesapeake Children's Museum and South Cherry Grove. There are also changes to salinity, pH, total suspended solids and dissolved oxygen, but on the whole the results aren't as bad as the huge amounts of debris released from the Conowingo Dam and settling in Spa Creek lead us to believe.
Heavy rain over the last week and the creek has elevated levels of enterococci making the water unsafe to swim in.
Average water temperature is now 78.8 degrees. That's up nearly 6 degrees from last week. And the rain has made the more shallows areas of Spa Creek unsafe for swimming. Red points on the map below indicate unsafe levels of bacteria.
Average water temps in Spa Creek now at 73 degrees. Water samples taken on Thursday show unsafe levels of bacteria at the Children's Museum bridge and the footbridge at the end of So. Cherry Grove. Everywhere else tested within safe swimming range.
Samples taken before the rain. Anne Arundel County recommends staying out of the water for 48 hours after a rainfall.
High levels of bacteria in shallow areas of Spa Creek, including the Chesapeake Children's Museum, around Truxtun Park and Hawkins Cove and at the end of So. Cherry Grove. Water temperatures is now at an average 71.6 degrees.
2018 begins the third year that there has been regular water testing on Spa Creek. May 3 was the first testing of the year and beginning May 24 the testing will be weekly. The map below shows all eleven sites being tested in 2018, and the first time since testing began that enterococci levels are at acceptable levels at each testing site. The water temperature is averaging 60 degrees throughout the creek.
