The present invention provides derivatized indicator compounds, such as pH indicator compounds, which can be covalently immobilized to a variety of solid substrates to produce an indicator pad. Such pads can be used to monitor water quality in variety of settings. In particular, the pads of the invention are useful in devices which monitor the quality of recreational water, such as water in swimming pools, hot tubs, and amusement park attractions. including water slides, and water-based rides. The present invention overcomes the limitations of commercially available pad chemistries.
