Sept 5, 2002 - Little Island Pond, Pelham, NH

Testing Results for June 19th, 9:00 am

NOTE: This is only a quick reference, detailed readings and figures are available below.

The following areas were tested;

Dam Outlet at Camp Runnels, Woekel Circle Inlet, a duplicate sample from Woekel Circle Inlet, South East Inlet on South Shore Drive and three separate depth ranges in the deep water area near the Girl Scout Camp. Deep water samples were taken at 2, 7 and 12 meters.

These areas were tested for;

1. Ph, which is important to the survival of fish and aquatic life. A satisfactory reading is 6.1—8.00 All areas tested within this range.

2. Turbidity which is caused by suspended mater (clay, silt, and algae). High turbidity readings are often found in water adjacent to construction sites. Turbidity readings below 0.1 are minimum and over 22 are maximum. All areas tested within accepted levels except Woekel Circle inlet which measured at 156 and 161.

3. Phosphorus is the most important water quality parameter measured in the lake. It is the nutrient that limits the algae's ability to grow and reproduce. Phosphorus sources around a lake typically include septic systems, animal waste, lawn fertilizer, laundry discharge, and road and construction erosion. All areas tested within accepted levels, 11-20 is average, except Woekel Circle inlet measured 168.

4. Chlorophyll is a measure of the pigment found in plants and gives an estimate of the concentration of algae. This test was only conducted in the deep water area. The pond measured 2.01 which is in the good range.

5. Water clarity was also measured in the deep water area and measured at 4.5 meters, which is in the exceptional range.

The pond tested well within accepted levels except at the Woekel Circle inlet. The DES suggests due to high levels of iron bacteria an iron and metals test is suggested and also testing at different points along the stream to pinpoint the source of the problem. Due to low rainfall the inlet dried up before any follow-up testing could be done.

This Woekel Circle area will be extensively tested in the spring of 2003.
