Notes
Nephelometer voltage 4.38 equals approx 0 NTU. THIS IS A CHANGE FROM 4.46 volts which corresponds to slightly more turbid water. But for this freshwater lake, I will accept virtually non turbid water. Surface pH was 7.62 and surface TDS was 68.
Bromine and chlorine test slightly present with Taylor strips. Doesn’t make a lot of sense but chlorides are in the lake and have been slightly increasing yr/yr. Likely due to winter salting. No real concerns at this time.
