Emerging Substances of Concern
• Global Organic Contaminants
• Pharmaceuticals and Personal Care
Products
• Endocrine Modulating Chemicals

Pharmaceuticals and Personal Care
Products (PPCPs)
 Includes prescription and over-the-counter (OTC)
medications, cleaning agents, cosmetics, nutritional
supplements, & skin care products
 Produced and used in larger volumes yearly
 Released via small quantity generators

 Commercial labs cannot analyze
PPCPs in the Environment
• DES has been tracking and assessing this
issue for several years
• Recent headlines regarding
pharmaceuticals in drinking water confirm
the importance of our efforts and focus on
this emerging issue

Medicine Use in NH
• In 2006, fifteen millions prescriptions
were filled in New Hampshire
• 2 out of 3 people that visit a doctor
leave with a prescription

Reducing pharmaceuticals in the
environment would require changes in:
1) When and how medicine is prescribed and
used;
2) How pharmaceuticals are designed and
engineered so they do not persist once
released in the environment;
3) Wastewater and drinking water treatment
technologies; and
4) How unused medicines are disposed of.
Medicines in the Environment
2008 AP Study
• 28 of 35 drinking water systems in the US had
detectable levels of pharmaceuticals
U.S. Geological Survey Monitoring Study
• 139 streams analyzed in 30 states
• Contaminants identified in 80% of these streams
• 82 contaminants identified (many were
pharmaceuticals)
• Co-occurrence common; average 7 distinct
contaminants identified per stream
Kolpin, D.W. et al. 2002. “Pharmaceuticals, hormones, & other organic
wastewater contaminants in U.S. streams, 1999-2000: A national
reconnaissance.” Environmental Science & Technology. 36(6):1202-1211.
Effects on Aquatic Organisms:
Cause for Concern
 Aquatic exposure – chemicals in the aquatic
environment can result in continuous,
multigeneration exposure.
 Feminization of fish - link to estrogen exposure?
Ex: Boulder Creek, CO: female white suckers outnumber males
by > 5 to 1; 50% of males have female sex tissue
(David Norris, Univ. of Colorado at Boulder)
 Effects of antidepressants on fish and frog
development?
Ex: Lab studies show low levels of common anti-depressants,
including Prozac, Zoloft, Paxil and Celexa, cause development
problems in fish, and metamorphosis delays in frogs
(Marsha Black, Univ. of Georgia)

Assessment of Medicine Disposal Options
White Paper Developed by DES
Summarizes
• Medicine use trends in the United States;
• Legal issues affecting how unused medicines may be
collected and disposed;
• Potential health and environmental issues associated
with releasing medicines to solid waste facilities and
wastewater disposal systems;
• Typical unused residential medicine disposal and
reuse practices in New Hampshire; and
• Options for managing unused medicines in New
Hampshire.
Expired Medication Disposal Habits
500 patients surveyed:
 54% disposed of
medications in the trash
Used All Prior
to Expiration
Returned to
Pharmacy
Did Not
Dispose
 35.4% flushed drugs down
the toilet or sink
 7.2% did not dispose of
medications
Flushed
Trashed
 2% used all medication prior
to expiration
 1.4% returned medications
to the pharmacy
Boehringer, S. “What’s the Best Way to Dispose of Medications?” (2004)
Unused Medicine Collection Events
• Require extensive planning to address
controlled substance, hazardous waste
and disposal requirements
• Need financial resources for pharmacists,
hazardous waste specialists and disposal
• NHDES recommended SOP available
• A guidance document is available from
Northeast Recycling Center.
DES Medicine Disposal Policies
Developed to Date
• Residential disposal policy developed
working with a workgroup of 80+
stakeholders
• Medicine collection and disposal SOP
• Draft medicine disposal policies for school
nurses
• Draft medicine disposal policies for
hospice
DES Medicine Disposal Policies
that Need to Be Developed
• Non hazardous and non controlled
substances in hospitals & institutions
• Physician offices
• Veterinarian
• Nursing homes

Message
Help Prevent Pollution, Poisonings and Drug Abuse!
Dispose of your Unneeded Medication
6 Steps to Safety
1) Pour medicine into a sealable plastic bag.
2) If the medicine is a solid, add a small amount of water to dissolve it.
3) Add any undesirable substance (such as dirt, coffee grounds or
kitty litter) to the liquid medicine in the plastic bag.
4) Seal the bag and immediately dispose of it in the trash for regular
pick-up.
5) Use marker to black out any personal contact information on the
empty medicine container prior to disposing of it in the trash.
6) For more information, consult www.nh.gov/medsafety.
Do NOT flush medicine down the toilet unless accompanying product
information instructs that it is safe to do so. Don't keep unneeded
medications in the home.
For more information or in case of an accidental poisoning, call the
poison center at 1-800-222-1222.
Medicine Disposal as Solid Waste
• Addresses environmental, drug abuse and drug
poisoning concerns
• Solid Waste in NH
– 15% Incinerated
– 85% in Landfills (almost all landfills are lined and capped)
• Most medicine disposed of in a landfill will be
retained by solids or break down through chemical
processes
• Leachate at lined landfills is collected and can be
treated.
• Solid waste disposal is readily available to
households.
Marketing of the Residential
Disposal Message
• New state website (www.nh.gov/medsafety)
• News articles will be published by various
organizations
• Letters will be sent to licensed health care
workers, municipal officials and solid waste
officials
• Posters will be made available to interested
organizations
