FREE BRIEF · GROUNDWATER
Iron and manganese can change what your chlorine sensor tells you
A 3-page brief for operators who’ve watched sensors foul: how fouling becomes a dosing problem, what the Compton Durville and Lakewood accounts showed, and a pilot plan that answers the fouling question.
What's inside
- ✓How fouling becomes a dosing problem — in five steps
- ✓Signs you’re in the loop — drift that resets after calibration, weekend drift
- ✓Six questions to ask any sensor — in Fe/Mn water
- ✓Compton Durville, high-iron borehole (MP5, historical) — 65 days, 73 cycles, and the 5-month inspection
- ✓Lakewood, CA groundwater (MP5, historical) — six months, minor Mn maintenance, within 0.04 ppm of CL17
- ✓A six-step side-by-side pilot plan — with a pilot record

3-page PDF. Includes a side-by-side pilot plan.
- Compton Durville (Wessex Water): electrodes clean after 5 months; reading essentially unchanged after a wipe (0.70 → 0.67 ppm)
- Lakewood: within 0.04 ppm of the Hach CL17 in a 2021 pilot
- Honest framing: no sensor is immune to deposit-forming water
Who it's for
Groundwater systems with Fe/Mn (wells, booster stations, small plants) that are tired of strip-downs and calibration drift, and engineers specifying analyzers for those sites.
