About Part 5


These documents are derivative of the various versions available from the New York State Department of Health. Compare the versions at NYSDOH, their division of water (Bureau of Water Supply Protection - BWSP version), the division of water's printable version, and versions obtained from requests to the NYSDOH or NYSDOS.

New York also has an official printed version. Actual wording of the rules is no longer published in the State Register, although notices and other useful information are.

Attempts have been made to correct the errors in Part 5 here. Small errors and omissions have been corrected. The intent of the code has not been altered. Since these documents admittedly do not match the versions available from NYSDOH, do not use them for litigation.

2014-01-27: Recent changes to Part 5 closely follow the National Primary Drinking Water Regulations (40CFR141). In some cases, Part 5 has not caught up with the Federal rules (e.g. Lead and Copper, DBP2). In some cases Part 5 is not as stringent as the Federal rules, which might be another way of saying Part 5 hasn't caught up. Always check 40CFR141 when considering rule based actions.


2012-08-24: Chapters finished.

2012-07-30: New "Ten States" water design manual announced. See their website. In process of updating this version (which includes extra links). Done through Chapter 2. NYSDOH plans to incorporate the 2012 edition into Part 5 (as Appendix A) - 2007 version is currently referenced.

2012-02-03: NYSDOH releases revised November 9, 2011 Part 5-1 (modification date 2012-01-12). In addition to the previously announced changes, various sections have style updates (commas, semicolons, capitalization, section naming convention, or other syntactic changes. These are not reflected in the section effective dates. Some orthographic inconsistencies do still remain. The revised edition may be reflective of the official version.

2007-07-03: The NYSDOS version appears to be up to date. Copies are available at $0.25/page from DOS.

2006-12-12: Updated based upon NYSDOH official revisions.

2006-12-11: Started updating to November 1, 2006 code, which incorporates the"Arsenic Rule". NYSDOH site has formatting errors and points to BWSP versions of the Tables (November 23, 2005) and 5C (May 26, 2004). Have not yet received Rule Maker version of changes from NYSDOH.

2006-01-25: On or about January 13, 2006, NYSDOH put the current versions of 5B, 5C, and 5D on the BWSP version (including the changes to 5-1.22) but did not update the effective dates. 5C has all the typographical errors the original 2004 version had. The NYSDOH site has the correct effective dates, but still points to the BWSP site for the tables and 5C. NYSDOH is missing 5D. The BWSP html and pdf versions generally agree with each other (typos in 5C, wrong dates).

2005-12-29: DOS version received. Adjustments made.

2005-12-27: Version here based on draft - DOS has not sent text yet. NYSDOH version updated (but has formatting, etc. errors).

2005-11-23: Of the complete versions, the NYSDOH web version is most correct, but lacks the tables and most appendices. The Water Division versions are out of date (especially Appendix C - their version is from 2003). The official printed version has not been seen.
