The Environment Agency’s tests of the River Ise as it flows through Kettering have shown up as clear.
The Environment Agency sent out an officer to test the water earlier this month after fears that dogs had been poisoned due to something in the water. So far, tests have shown no problems.
A spokesman for the agency said: “Water quality test results show that levels of nitrogen, ammonia, chlorine and oxygen are all OK and normal.
“We are still waiting for one further test result but do not anticipate this showing anything abnormal. We have had no reports of fish or other aquatic life being adversely affected.”
