MODEL AQUATIC HEALTH CODE
30
AND NSF/ANSI 50 CERTIFICATION
The Model Aquatic Health Code (MAHC) is a set
of guidelines published by the Centers for Disease
Control and Prevention (CDC). This document brings
together the latest knowledge based on science and
best practices to help state and local government
offi cials develop and update pool codes. They may
use the code in whole, choose to use parts, or modify
to fi t their needs. Use of the MAHC is intended to save time and
resources spent individually developing and updating codes across
the country, while giving agencies the benefi t of the latest science
and best practices to help keep pools fun, safe, and healthy.
The MAHC requires NSF/ANSI 50 certifi cation of water quality
testing devices (WQTD) used in recreational facilities such as public
swimming pools, interactive fountains, and Waterparks. Third-party
certifi cation to NSF/ANSI 50 allows manufacturers to make verifi ed
claims regarding the performance, accuracy and operating range of
their WQTD. The performance testing of a WQTD involves accuracy
and repeatability testing on two different lots of new production.
Unlike most NSF/ANSI 50 certifi cations, WQTDs require follow-up
testing of the product at the end of the manufacturer's specifi ed
shelf life. Certifi ed products are given an accuracy rating to one of
three levels: L1, L2 or L3, with L1 being the highest accuracy rating.
