Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 611 - PRIMARY DRINKING WATER STANDARDS › Subpart N - INORGANIC MONITORING AND ANALYTICAL REQUIREMENTS › Section 611.609 - Determining Compliance

Current through Register Vol. 48, No. 28, July 12, 2024
Compliance with the MCLs of Section
				  611.300
				  or
				  611.301
				  (as appropriate) must be determined based on the analytical results obtained at
				  each sampling point.
a) For suppliers
				that monitor at a frequency greater than annual, compliance with the MCLs for
				antimony, arsenic, asbestos, barium, beryllium, cadmium, chromium, cyanide,
				fluoride, mercury, nickel, selenium, or thallium is determined by a running
				annual average at each sampling point.
1) If
				the average at any sampling point is greater than the MCL, then the supplier is
				out of compliance.
2) If any one
				sample would cause the annual average to be exceeded, then the supplier is out
				of compliance immediately.
3) Any
				sample below the method detection limit must be calculated at zero for the
				purpose of determining the annual average.
BOARD NOTE: The "method detection limit" is different from
				  the "detection limit," as set forth in Section
				  611.600. The
				  "method detection limit" is the level of contaminant that can be determined by
				  a particular method with a 95 percent degree of confidence, as determined by
				  the method outlined in appendix B to 40 CFR 136, incorporated by reference at
				  Section
				  611.102.
4) If a system fails to collect the required
				number of samples, compliance (average concentration) will be based on the
				total number of samples collected.

Analytical methods are from documents incorporated by
				  reference in Section 611.102. The substantive rules
				  mostly reference these by a short name Section
				  611.102(a)
				  defines. Section 611.101 defines other

				arsenic, barium, beryllium, cadmium, calcium, chloride, chromium, copper, lead,
				nickel, selenium, sodium, sulfate, and thallium with digestion or directly
				without digestion, and other analytical procedures.
BOARD NOTE: Because a laboratory determines MDLs it reports
				  under USEPA 200.7 (94) and
				  USEPA 200.9 (94)
				  using a 2a preconcentration step during sample digestion, MDLs the laboratory
				  determines analyzing samples by direct analysis (i.e., no sample digestion) are
				  higher. For direct analysis of cadmium and arsenic using USEPA
				  200.7 (94) and
				  arsenic using SM 3120 B (89), SM 3120 B (93), or SM 3120 B (99), it may be
				  necessary to engage in sample preconcentration using pneumatic nebulization to
				  achieve lower detection limits. Direct analysis of antimony, lead, and thallium
				  using USEPA 200.9 (94);
				  antimony and lead using SM 3113 B (89), SM 3113 B (99), or SM 3113 B (10); and
				  lead using ASTM D3559-96 D, ASTM D3559-03 D, ASTM D3559-08 D, or ASTM D3559-15
				  D may require preconcentration, unless the laboratory makes multiple in-furnace
				  depositions.

Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 611 - PRIMARY DRINKING WATER STANDARDS › Subpart N - INORGANIC MONITORING AND ANALYTICAL REQUIREMENTS › Section 611.630 - Special Monitoring for Sodium

Current through Register Vol. 48, No. 28, July 12, 2024
a) CWS suppliers must collect and analyze one
				sample per plant at the entry point of the distribution system for the
				determination of sodium concentration levels; samples must be collected and
				analyzed annually for CWSs utilizing surface water sources in whole or in part,
				and at least every three years for CWSs utilizing solely groundwater sources.
				The minimum number of samples required to be taken by the supplier is based on
				the number of treatment plants used by the supplier, except that multiple wells
				drawing raw water from a single aquifer may, with the Agency approval, be
				considered one treatment plant for determining the minimum number of samples.
				The Agency must require the supplier to collect and analyze water samples for
				sodium more frequently in locations where the sodium content is
				variable.
b) The CWS supplier must
				report to the Agency the results of the analyses for sodium within the first 10
				days of the month following the month in which the sample results were received
				or within the first 10 days following the end of the required monitoring period
				as specified by SEP, whichever of these is first. If more than annual sampling
				is required, the supplier must report the average sodium concentration within
				10 days of the month following the month in which the analytical results of the
				last sample used for the annual average was received.
c) The CWS supplier must notify the Agency
				and appropriate local public health officials of the sodium levels by written
				notice by direct mail within three months. A copy of each notice required to be
				provided by this subsection must be sent to the Agency within 10 days after its
				issuance.
d) Analyses for sodium
				must be conducted as directed in Section
				611.611(a).

Analysis of the Phase II, Phase IIB, and Phase V SOCs for the
				  purposes of determining compliance with the MCL must be conducted as
				  follows:
a) Definitions. As used in
				this Section, the following terms will have the following meanings:
"Detect" or "detection" means that the contaminant of
				  interest is present at a level greater than or equal to the "detection
				  limit".
"Detection limit" means the level of the contaminant of
				  interest that is specified in subsection (r).
BOARD NOTE: This is a "trigger level" for Phase II, Phase
				  IIB, and Phase V SOCs inasmuch as it prompts further action. The use of the
				  term "detect" or "detection" in this Section is not intended to include any
				  analytical capability of quantifying lower levels of any contaminant, or the
				  "method detection limit".
b) Required Sampling. Each supplier must take
				a minimum of one sample at each sampling point at the times required in
				subsection (q).
BOARD NOTE: See the Board note appended to Section
				  611.311(c)  for
				  information relating to implementation of requirements relating to aldicarb,
				  aldicarb sulfone, and aldicarb sulfoxide.
c) Sampling Points
1) Sampling Points for GWSs. Unless otherwise
				provided in a SEP, a GWS supplier must take at least one sample from each of
				the following points: each entry point that is representative of each well
				after treatment.
2) Sampling Points
				for an SWS or Mixed System Supplier. Unless otherwise provided in a SEP, an SWS
				or mixed system supplier must sample from each of the following points:
A) Each entry point after treatment;
				or
B) Points in the distribution
				system that are representative of each source.
3) The supplier must take each sample at the
				same sampling point unless the Agency issues a SEP that designates another
				location as more representative of each source, treatment plant, or within the
				distribution system.
4) If a system
				draws water from more than one source, and the sources are combined before
				distribution, the supplier must sample at an entry point during periods of
				normal operating conditions when water is representative of all sources being
				used.
BOARD NOTE: Subsections (b) and (c) derive from

Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 611 - PRIMARY DRINKING WATER STANDARDS › Subpart Q - RADIOLOGICAL MONITORING AND ANALYTICAL REQUIREMENTS › Section 611.731 - Gross Alpha

Current through Register Vol. 48, No. 28, July 12, 2024
Monitoring for Gross Alpha Particle Activity, Radium-226,
				  Radium-228, and Uranium
a) A CWS
				supplier must monitor to determine whether it complies with Section
				611.330(b),
				(c), and (e). For monitoring gross alpha
				particle activity, radium-226, radium-228, uranium, and beta particle and
				photon radioactivity in drinking water, "detection limit" is defined as in
				Section 611.720(c).
1) Applicability and Sampling Location for an
				Existing CWS Supplier. An existing CWS supplier using groundwater, surface
				water, or both groundwater and surface water must sample at every entry point
				to the distribution system representing all sources the supplier uses (a
				sampling point) under normal operating conditions. The supplier must take each
				sample at the same sampling point, unless conditions make another sampling
				point more representative of each source or the Agency designates a
				distribution system location under subsection (b)(2)(C).
2) Applicability and Sampling Location for a
				New CWS Supplier. A new CWS supplier or a CWS supplier using a new source of
				water must begin initial monitoring for the new source within the first quarter
				after beginning to use the source. A CWS supplier must conduct more frequent
				monitoring as directed by the Agency in a SEP due to possible contamination or
				changes in the distribution system or treatment processes that may increase the
				concentration of radioactivity in the supplier's finished water.
Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 611 - PRIMARY DRINKING WATER STANDARDS › Subpart Q - RADIOLOGICAL MONITORING AND ANALYTICAL REQUIREMENTS › Section 611.732 - Beta Particle and Photon Radioactivity

Current through Register Vol. 48, No. 28, July 12, 2024
Monitoring and Compliance for Manmade Radioactivity. To
				  determine compliance with the maximum contaminant levels in Section
				  611.330(d)  for
				  beta particle and photon radioactivity, a supplier must monitor at a specified
				  frequency:
a) If the Agency issues a
				SEP designating a CWS supplier (either a surface water or groundwater supplier)
				as vulnerable, the supplier must sample for beta particle and photon
				radioactivity. The supplier must collect quarterly samples for beta emitters
				and annual samples for tritium and strontium-90 at each entry point to the
				distribution system (hereafter called a sampling point) beginning within one
				quarter after the Agency issued the SEP. A supplier the Agency designates must
				continue to sample until the Agency issues a new SEP removing the designation.
1) If the gross beta particle activity minus
				the naturally occurring potassium-40 beta particle activity at a sampling point
				has a running annual average (computed quarterly) less than or equal to 50
				pCi/L (the screening level), the Agency may reduce the monitoring frequency at
				that sampling point to once every three years. A supplier must collect all
				required samples during the reduced monitoring period.
2) For a supplier in the vicinity of a
				nuclear facility, the Agency may issue a SEP allowing the CWS supplier to use
				environmental surveillance data the nuclear facility collected in lieu of
				monitoring at the supplier's entry points upon determining the nuclear
				facility's data are pertinent to the supplier's system. If a release from a
				nuclear facility occurs, a supplier using surveillance data must begin
				monitoring at the CWS's entry points under subsection (b)(1).
Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 611 - PRIMARY DRINKING WATER STANDARDS › Subpart Q - RADIOLOGICAL MONITORING AND ANALYTICAL REQUIREMENTS › Section 611.733 - General Monitoring and Compliance Requirements

Current through Register Vol. 48, No. 28, July 12, 2024
a) The Agency may issue a SEP requiring more
				frequent monitoring than Sections
				611.731 and
				611.732 specify or requiring
				confirmation samples. The supplier must average the results of the initial and
				confirmation samples to determine whether it complies.
b) A PWS supplier must monitor at the time
				the Agency designates during each compliance period.
c) Compliance. A supplier must determine
				whether it complies with Section
				611.330(b) through
				(e) based on the analytical results it
				obtains at each sampling point. If one sampling point violates an MCL, the
				supplier violates the MCL.
1) A supplier
				monitoring more than once per year must run an annual average at each sampling
				point to determine whether it complies with the MCL. If the average of any
				sampling point is greater than the MCL, the supplier does not comply with the
				MCL.
2) A supplier monitoring more
				than once per year immediately does not comply with an MCL if any sample result
				would cause the running average to exceed the MCL at any single sampling
				point.
3) A supplier must include
				all samples it takes and analyzes under this Section and Sections
				611.731 and
				611.732 to determine whether it
				complies, even if that number is greater than the required minimum.
4) If a supplier does not collect all
				required samples to determine its compliance based on a running annual average
				of quarterly samples, the supplier must determine whether it complies based on
				the running average of the samples it collected.
5) If a sample result is less than the
				detection limit, the supplier must use zero to calculate the annual average,
				unless the supplier uses a gross alpha particle activity in lieu of radium-226
				or uranium. If the gross alpha particle activity result is less than the
				detection limit, the supplier must use one-half the detection limit to
				calculate the annual average.
